AWS Cloudwatch interview Questions & Answers


Ques: 5). Tell us about your proudest achievement.

Answer:

My most significant accomplishment was in my former work as a cloud specialist. I worked for a firm that was experiencing a shortage of cloud professionals at the time. Adding more cloud professionals to the tea sounded expensive because the company was small. I recommended to the company's president how we could automate some tasks. I helped him because he didn't know what to do. Some operations, such as backups at specific intervals and resource pattern monitoring, become simple to automate. At the end of the day, the corporation was able to achieve its goal while spending very little money.

AWS(Amazon Web Services) Interview Questions & Answers


Ques: 8). When a person types the domain name into a web browser, how can you bring the website content back to them?

Answer: 

As you may be aware, every website has its own domain name system (DNS). As a result, the DNS and each website would be assigned a unique internet protocol or IP address. When entering a domain name into a web browser, the following scenarios may arise:

  • Your input or signal will be received as a request by the web server hosting services. Following that, the web server hosting firm will undoubtedly respond to your request with appropriate outcomes.
  • When you use a browser, it sends a request to the internet protocol address, which is linked to the domain name automatically.
  • The IP address is sometimes returned to the user by the domain name system.
  • To deliver back the website content to the users, the web browser will contact a domain name system.

The salary of a cloud support engineer in AWS is determined by your abilities and performance during the AWS support interview. So, if you want a higher income in your AWS work, make sure you answer the interviewer's questions properly and confidently.


AWS Database Interview Questions & Answers


Ques: 9). Give some instances of typical networking commands you've used.

Answer:

It's worth noting that the AWS stack is mostly based on Linux, and its cloud design makes it extremely network-dependent. As a result, regardless of your history as a system administrator, database administrator, or bigdata administrator, your AWS interview could be about networking. Learn how to use these basic networking commands:

The first step when a system is unreachable is to ping the host to ensure it is up and functioning.

ping host – This pings the host and output results

Domain related commands as AWS has become preferred hosting for major itnernet based companies, SaaS firms

To get DNS information of the domain use – dig domain

To get whois information on domain use – whois domain

Host reverse lookup – dig -x host

Download file – wget file

To continue stopped download – wget -c file


ActiveMQ Interview Questions & Answers


Ques: 10). What does the term "fault tolerant" mean?

Answer: 

When a set number of failures and issues occur, the fault tolerant process is used to control or manage the faults. It's one of the AWS Cloud's most critical self-healing features. This has become a crucial Amazon AWS cloud support engineer interview question and answer because, while the question appears easy, the answer is really complex.

It is a system property that allows a system to work or continue to work in the face of numerous failures at any moment. It is a computer system capability that makes the work of users much more reliable. Such systems are intended to safeguard any present functional system against numerous failures that may occur at any given time. It ensures that any network or system maintains the needed level of continuity in order to avoid the negative effects of interruptions.

 

Ques: 11). What exactly is a procedure? In Linux, how do you manage processes: -

Answer:

When a command is issued in a Linux/Unix based OS, a process is launched or created. In simple terms, an instance of a programme is produced while it is running in an operating system. This is how it works. Process management commands are useful in Linux for managing processes.

ps – this is the commonly used process management command to start with. ps command provides details on currently running active processes.

top – This command provides details on all running processes. ps command lists active processes whereas top lists all the processes (i.e) activity of processor in real-time. This includes details on processor and memory being used.

kill – To kill a process using the process id kill command is used. ps command provides details on process id. To kill a process issue kill pid.

killall proc – This command is same as kill command. To kill all the processes by name proc we can use this

 

Ques: 12). In Amazon Web Services, Emphasize The Importance Of Buffer.

Answer:

An Elastic Load Balancer ensures that incoming traffic is spread as efficiently as possible across multiple AWS instances. A buffer will synchronise several components and make the setup more elastic in the event of a burst of load or traffic. The components are prone to receiving and processing requests in an unreliable manner. The buffer produces an equilibrium between diverse devices and crafts them to function at the same rate, allowing for faster service delivery.

 

Ques: 13). What Is An Amazon Web Services Availability Zone?

Answer: 

A collection of your AWS resources is made up of availability zones (within a region). For high availability and fault tolerance, properly built applications will use several availability zones. Each AZ has a low-latency direct connection to the others, and each AZ is separated from the others to ensure fault tolerance.

 

Ques: 14). What Happens When A User Types A Domain Name Into A Web Browser? 

Answer:

A DNS server is contacted by the web browser, which requests the IP address associated with the domain name.

The IP address is returned to the Browser by the DNS server.

A request (for content) is sent by the browser to the IP address associated with the domain name.

The request is received by the web server holding web content, which then provides the web content back to the user.

 

Ques: 15). What are the various kinds of routing protocols?

Answer:

The routing protocol is a crucial word that describes how different routers communicate. The routing protocol can be implemented by two nodes in a computer network. The following are some of the most often used routing protocols:

  • Routing information protocols (RIP)
  • Interior Gateway Protocol (IGP)
  • Open shortest path first (OSPF)
  • Exterior Gateway Protocol (EGP)
  • Border Gateway Protocol (BGP)
  • Intermediate system to intermediate system (IS-IS)

These are some of the most commonly utilised routing kinds among system users. The interviewer may pose this topic as one of the most typical AWS cloud support engineer interview questions. So, remove your doubts regarding the network, infrastructure, and other related topics before embarking on such interviews.

 

Ques: 16). What Does The Elasticity Concept Mean For AWS Consumers and Enterprise Users?

Answer:

Elastic systems allow for the rapid addition and subtraction of servers as demand (user base) on a web application increases and drops. Getting rid of unused servers might save a lot of money.

 

Ques: 17). What is the primary distinction between a private and a public subnet?

Answer:

A private subnet normally directs traffic to a NAT instance. In the private subnet, only private IP and internet traffic is routed. A public subnet, on the other hand, requires a public IP address to communicate. The major distinction between a private and a public subnet is this.

 

Ques: 18). How would you persuade a customer to switch to AWS?

Answer: 

These types of questions might be posed during your interview to assess your mental agility, persuasion power, and speaking ability. As a candidate, you must remain cool and optimistic under such circumstances. If this question is asked during your interview, you must respond honestly. You can state things like "I have experience dealing with such customers" and "I have knowledge and expertise dealing with such consumers," and so on in your response. You can persuade customers by describing the capabilities and advantages of using the AWS cloud. As a result, job candidates can readily respond to this question based on their degree of thinking and speaking ability.

 

Ques: 19). Do you understand how the internet works in your area?

Answer: 

There are several internet tiers and web servers available all over the world, which serve as the internet's communication path. Without the internet's ingenuity, sharing could not have progressed as quickly as it has. 

Circuit switching is a word used on the internet to describe how the internet works in your current context. Another internet technology is packet switching, which makes it much easier for the internet to communicate or distribute information. This is one of the most common AWS cloud support engineer interview questions because it gives you some fundamental internet knowledge.

Packing switching is the process of separating a single internet server into numerous servers. There is no requirement for a physical path for the computer. The internet's supporting equipment would be sufficient to enable better and more dependable internet sharing among a large number of computers.

 

Ques: 20). In Linux or UNIX-based operating systems, how can you easily manage processes?

Answer:

When a user types a command into a Unix operating system, it starts working. When an operating system is started, an instance is created automatically. To manage processes in Linux OS, I would use the PS processing command. This command displays information about the currently running processes and activities. When running Linux, I can also use TOPIS as a process management tool. 

This command can be used to acquire statistics about the operating system's activity. To kill running processes, I would also use the Kill command. In a Linux-based operating system, press Ctrl+Alt+Del to terminate all programmes. I would use the killall command. With these commands, I would be able to take full control of the operating system and manage its processes effectively.

Top 20 UX Design Interview Questions & Answers


Ques. 1). How would you improve our product's user experience(UX)?

Answer:

Another area where preparation can truly help you succeed in the interview is here. Before you start, look over the product and think about how the user experience could be enhanced. You'll be able to speak in depth about how the interaction design or overall user experience could be enhanced by the time the question comes up.


Ques. 2). What is the difference between UX, UI, and Other Design Disciplines?

Answer: 

For this particular interview, this is a common question.

• The interviewer wants to know if you understand the tasks and responsibilities of a UX designer and how they differ from those of other designers, as well as if you can use UX design concepts to cooperate with other design disciplines. The trick is to first research the roles that this organisation demands, and then put out your answers.

• Try to explain that other disciplines are subsets of UX design and that design disciplines change with products, but that with UX design, the basic structure will remain consistent.


Ques. 3). How are you going to improve our product?

Answer: 

The interviewer wants to know if you did your homework on the job and the firm. If it's a major company, only provide an other answer if it's absolutely necessary, and only in conformity with the company's current trend. Diplomacy can also be used. Don't be scared to express yourself; yet, subtlety and precise language will be highly received. If it's a start-up, avoid criticising the product and instead focus on making it famous. Make sure you're familiar with the intended audience.


Ques. 4). How do you go about working on and processing a design?

Answer: 

You can also show them your portfolio in this scenario. Discuss some of your best work or a favourite design you've developed. This manner, you'll be able to show them how you work. Again, try to explain in terms of your work as a UX designer for that organisation in either situation.


Ques. 5). What is the User Experience (UX)?

Answer:

When responding to this question, avoid using the standard definition from your textbook. Take a look at the other side of the coin. You've come because you require this position. So consider it from the standpoint of your profession.

Tell them why it's important to the project. Perhaps you could give an intriguing example to demonstrate how well you understand what you're going to perform. Make sure to include user research, information architecture, user interface design, experience strategy, usability, and interaction design in your plan.

Create a scenario in which you may describe how you will design for your audience. What important is that the user experience is centred on the user.


Ques. 6). Have You Run Into Any Issues While Developing Solutions for Your UX Design Project?

Answer:

It is your responsibility as a UX designer to inform them about how you handle your assignments. Your interviewer wants to know how you work on a project, including your software processes and how you break down each project into smaller pieces before tackling it. You must outline how you set goals for each of your projects, as well as how you do research, produce prototypes, effectively communicate with your team about the goals, and how your team's combined efforts will lead to the final product.

You can tell them about a specific experience you had while working on a particularly difficult project. Tell them what went wrong, why it happened the way it did, how you fixed it, and how you'd use your knowledge in the future.


Ques. 7). How do you go about identifying the features you'd like to include in your design?

Answer:

This is one of the most often asked questions in UX design interviews. Make sure you're ready for this. Specifically, they want to know if you can validate or reject a theory. This is to see how you came up with a different answer.

This is a difficult question to answer. It could be asked in a variety of situations. If this question was posed in the context of developing a new piece of software, you can always express your thoughts on what the minimum viable product should be (MVP).

You can concentrate on the principles of product strategy if it centres around an existing product. You can think about the response in terms of 'who the user is,' 'what are the aims of your user,' 'will the user be concerned about the feature, and how competent is the feature of fixing problems,' and so on.

This is where user research can be used to confirm design decisions. A great deal of user data aids designers in determining what has to be done next. If you have adequate data and a clear image of the user's goals, you can figure out which aspects are the most in line with those goals.


Ques. 8). What do you think the next big thing in UX will be?

Answer:

They want to know how well you know what you're doing and whether you're thinking about what might happen in the future.

This is an excellent opportunity for you to demonstrate what you know and what you excel at. You could discuss new technologies that can help convert a design to code and save a lot of time.

On blogs like UXBooth, Design Modo, Intercom blog, User Testing blog, and others, you can always get inspiration and ideas on what drives and inspires you.

There are plenty additional online resources where you may get ideas for the latest trends and inspiration for what you might be asked in your next UX interview. Keep an eye out for motivation.


Ques. 9). What is "Design Thinking" and how does it work?

Answer:

With the recent shift in the kind of employment people are choosing to explore their creative and imaginative sides, the UI/UX Design sector is the greatest option and has been fast growing. People are interested in UI/UX Design employment because of the high demand, as firms recognise the importance of designers in their strategy teams. The top ten UX UI designer interview questions are listed below.

Companies are recruiting more UI/UX designers to produce products that help them achieve their objectives while also meeting the expectations of their customers.

Companies have hired more UX designers as a result of the present COVID-19 issue.

Even if a person has excellent UI/UX design talents, they must have excellent communication skills to impress the interviewer. The online interview system has undoubtedly made it more difficult to communicate with the interviewer.

The interview process is a vital stage in getting a job as a UI/UX designer since it evaluates your logical reasoning, problem-solving ability, and creative thinking abilities, which are the most significant qualities of a UX designer, in addition to your portfolio.


Ques. 10). What is the difference between UI and UX design?

Answer:

It appears to be a too broad and fundamental inquiry. Right? Just keep in mind that the interviewer does not want you to give a textbook definition to this question.

Use a basic example from your everyday life and describe it in a way that even a layperson may comprehend. For example, two teacups, one with a handle and the other without. Explain why the user prefers one cup over the other. Let the interviewer know that the major goal of UX design is to improve and enhance the consumer experience. The greatest way to demonstrate UX Design is to use real-world examples.


Ques. 11). How do you go about designing? Describe the situation in your own words.

Answer:

Make sure you don't take the easy way out here. Simply provide the interviewer with a basic knowledge of the generic process and completely define it in your own words. He or she is curious about your approach to the procedure. Ensure that the research strategy is communicated. Discuss the design process with the interviewer and explain why you chose to design things the way you did. Finally, discuss testing and customer feedback. What methods did you use to test your design?

Explain your definition of UX design and how you see it in relation to people's requirements, as well as the necessity of getting to know the people you're designing for. As a UX designer, you must consider consumer feedback and tailor your product accordingly.

Also, incorporate some of the language features that designers use (not jargon). Describe how you moved from simple sketches (e.g., on a scrap of paper) to complex prototypes (e.g., using Adobe XD or Figma) to interactive prototypes. How many prototype revisions were there, and how did they differ from the final product?


Ques. 12). What is "Design Thinking" and how does it work?

Answer:

Design Thinking is an important word that all UX designers should be familiar with, and it might be a knowledge testing question that is also vital for job selection. Design thinking is a method of problem-solving that is both practical and creative. It's all about gaining insight into your target audience's unmet wants. It's a type of solution-based procedure with the goal of achieving a positive future outcome.

Instead of going completely textbook here, say that it's a method in which people come first, and their preferences, needs, and behaviour affect the entire product design process.As a result, incorporate the following basic steps in your summary: -

1. Take advice from others.

2. Look for trends

3. Principles of Design

4. Make something concrete

5. Constantly iterate

Take a case study that you completed and explain the various stages of the process as well as the methodologies that you used at each step. Remember to explain the "Why" behind each activity as you go through the process.


Ques. 13). Failure of UX projects. What did you discover?

Answer:

Remember that being a UX designer entails a lot of problem solving. As a result, make sure to lead the interviewer through the process. The interviewer will assess your problem-solving abilities, so remain calm and explain what, why, when, and how the project failed.

Address the problem and the grounds for its occurrence. Also, if you made a mistake, accept it and be honest about it. Designers value forthrightness. Giving a failure-related lesson demonstrates your integrity and commitment to your craft.


Ques. 14). Do you work well with others?

Answer:

It's a question that practically every interviewer asks. Don't go too far with your response to this question. Instead, staying somewhere in the middle is always a good choice. If you concentrate on your own job, the interviewers may conclude that you are not suited to operate in a team environment.

As a result, attempt to frame your response by stating that while you appreciate working in collaborative workplaces, you know how to prioritise tasks and set your own deadlines when given individual responsibility. This will demonstrate that you aren't prone to extremes and can work in a variety of settings.


Ques. 15). What are some of your UX design inspirations?

Answer:

When answering this question, be sincere and truthful. Do not be bashful about talking about design podcasts, blog posts, online chats, or in-person meetups. There is no right or incorrect response to this question because each designer finds inspiration in his or her own unique method.

Don't say something that you don't mean. Saying that you read all of the latest novels when you don't is a bad option because you won't be able to answer a specific follow-up inquiry in this scenario. Make things as simple as possible for yourself.


Ques. 16). Tell me about a time when a project didn't go according to plan. What did you do to make it better?

Answer:

Interviewers frequently ask, "Tell me about a time when...", and you may be asked for multiple "times when." In this case, the interviewer is interested in learning more about your problem-solving abilities. They'll also want to see if you can maintain your composure under pressure. Use historical instances. Everyone has been dealt with a difficult undertaking at some point in their lives.

Consider bringing up a period when there was a snag in the process, budget cuts, or unforeseen circumstances. However, avoid pointing fingers. Also, make sure you don't offer an example when the problem was caused by your own irresponsibility.


Ques. 17). What are three of your greatest assets?

Answer:

This is the time to brag about yourself. Just make sure that your skills match what the organisation is seeking for. We recommend going over the job description again to prepare for this question. Consider the following job description from Nextdoor in San Francisco:

Nextdoor is looking for someone who can develop "extremely engaging, enjoyable, and user-centered experiences," as you can see. They're looking for someone who can "guide team members" and "take part in cross-functional brainstorming, discussion, and design reviews." As a result, you may list your top three strengths as follows:

Empathy allows you to take a step back, set your biases aside, and prioritise the customer's requirements.

Leadership: At your previous position, you mentored several junior designers and enjoyed seeing them progress.

Collaboration: You enjoy discussing with other teams because each one has a unique set of skills and adds something new to the table.

When an interviewer asks about your strengths, you may expect them to inquire about your flaws as well.


Ques. 18). What is your greatest flaw?

Answer:

It may seem paradoxical to tell a potential employer something you're not good at. It is, however, a common query. If at all feasible, frame your responses as good flaws. Take a look at NextDoor's job description in San Francisco to discover what qualifications they're seeking for:

They're looking for someone who can handle a "fast-paced startup," as you can see. This is code for "there's a lot going on and a lot of change," therefore one flaw may be: "If I'm not challenged or kept active, I grow bored."

This demonstrates to the interviewer that you can work in a fast-paced, demanding workplace. Alternatively, you may say:

"It's been suggested that I send too many emails outside of business hours."

This demonstrates that you are a hard worker who is always on, even when you are at home. (However, be sure it's the job you want!)


Ques. 19). How Do You Deal With Negative Feedback?

Answer:

Say more than "well." Instead, explain you're open to all kinds of comments as long as it helps you improve as a UX designer. Give a few of examples of comments you've gotten on a project and how you dealt with it.

You could mention a prior supervisor who was quick to give critical input, but you preferred to call it "constructive criticism." Let's say you'd rather get input from internal sources than from actual customers once a product launches. You might inform the interviewer that you and your bosses are all on the same team and that you'd like to talk about anything you could improve on.


Ques. 20). Tell me about a time when you disagreed with a recommendation made by your team. What exactly did you do?

Answer:

The best replies are those that are based on data. Keep that in mind. When possible, discuss how data and proven results can be used to make smart recommendations and business decisions.

In this case, you should discuss whether the recommendation was founded on empirical evidence or was entirely subjective. If possible, give an example of a subjective recommendation (e.g., "the boss likes the colour pink, so we're making the button pink").For instance, you may remark that your user research led you to disagree with the team's recommendation. Perhaps you've observed individuals engaging with prototypes and noticed that they prefer the colour blue over the colour pink. If possible, propose conducting another round of usability testing to compare a pink button against a blue button in an A/B test. Subjective opinions are less effective at resolving disagreements than objective data.

Ques: 3. What type of performance can you expect from Elastic Block Storage? How do you back it up and enhance the performance?

Answer: 

Performance of an elastic block storage varies i.e. it can go above the SLA performance level and after that drop below it. SLA provides an average disk I/O rate which can at times frustrate performance experts who yearn for reliable and consistent disk throughput on a server. Virtual AWS instances do not behave this way. One can backup EBS volumes through a graphical user interface like elasticfox or use the snapshot facility through an API call. Also, the performance can be improved by using Linux software raid and striping across four volumes.
