AWS Cloud Interview Questions and Answers

 

Ques. 1): How effective are Lightsail instances?

Answer:

AWS particularly designed Lightsail instances for usage with web servers, developer environments, and tiny databases. Such tasks occasionally require a performance burst but do not frequently or routinely demand the entire CPU. Burstable performance instances, which Lightsail employs, offer a basic amount of CPU performance with the option to burst over it. This approach protects you from the inconsistent performance or other frequent negative effects that you may normally see from over-subscription in other situations while enabling you to obtain the performance you need, when you need it.

Use Amazon EC2 if you want highly customizable settings and instances with consistently good CPU performance for applications like video transcoding or HPC workloads.

Ques. 2): How do DNS records work?

Answer:

DNS is a widely used service that converts domain names like www.example.com into the numerical IP addresses used by computers to communicate to one another, such as 192.0.2.1. You may quickly link the public IPs of your Lightsail instances to your registered domain names, such as photos.example.com. In this way, Lightsail automatically converts human readable names like example.com that people put into their browsers into the IP of the instance you wish to send them to. These translations are all referred to as DNS queries.

It's crucial to understand that you must register a domain in Lightsail before using it. You can register new domains using Amazon Route 53, or your preferred DNS registrar.

Ques. 3): What can I do in Lightsail using tags?

Answer:

With tags, you can categorise and filter your resources in the Lightsail interface and API, keep track of and arrange your charges in your bill, and set access management rules to control who may see or alter your resources. With the use of tags, you can:

Organize - View and manage resources based on the tags you've given them using the Lightsail interface and API filters. This is helpful if you have a lot of resources of the same type since you can easily recognise a particular resource based on the tags you've given it.

Cost-allocate - By identifying your resources and setting "cost allocation tags" in the billing interface, you may track and distribute expenses across various projects or users. You may, for instance, break out your bill and analyse your expenditures by client or project.

Using AWS Identity and Access Management rules, you can manage access and limit who may create, update, and remove Lightsail resources. You can work more effectively with people on projects without having to grant them complete access to your Lightsail resources thanks to this.

Ques. 5): What are photographs?

Answer:

Point-in-time backups of instances, databases, or block storage devices are known as snapshots. You may take a snapshot of your resources at any moment, or you can instruct Lightsail to take snapshots for you by turning on automatic snapshots for instances and discs. Snapshots can be used as starting points for building new resources or when backing up data. All the information required to recover your resource is in a snapshot (from the moment when the snapshot was taken). The rebuilt resource starts out as an identical clone of the old resource that was used to construct the snapshot when you restore a resource by building it from a snapshot.

You can manually take snapshots of your Lightsail instances, disks, and databases, or you can use automatic snapshots to instruct Lightsail to take daily snapshots of your instances and disks automatically.

Ques. 9): What can I do with the block storage in Lightsail?

Answer:

Similar to an individual hard drive, Lightsail block storage offers extra storage volumes (referred to as "connected discs" in Lightsail) that you may attach to your Lightsail instance. Applications and software that need to split off specialised data from their core services can benefit from attached discs. They can also be used to preserve application data in the event that your instance and system disc experience a failure or other problem. Applications or software that often access their stored data might benefit from the constant performance and reduced latency provided by attached drives.

Solid-state discs are used in Lightsail block storage (SSD). This kind of block storage aims to handle the great majority of Lightsail workloads by balancing affordability and performance. Adopt EC2 with GP2 or Provisioned IOPS SSD storage in place of Lightsail for clients whose applications need consistent IOPS performance, high throughput per disc, or are running sizable databases like MongoDB, Cassandra, etc.

Ques. 19):  What kind of usage does Lightsail CDN encourage?

Answer:

Amazon To make the cost of utilising the service straightforward and predictable, Lightsail CDN distributions are built using fixed-priced bundles of data transport. A month's worth of consumption is covered by a distribution package. Distribution bundles may not be used for purposes other than those for which they were designed, such as repeatedly upgrading or downgrading bundles or employing an abnormally high volume of distributions from a single origin. Workloads that need a lot of requests per second or a lot of streaming video are also not allowed. Your data services or account may be throttled or suspended if you engage in these actions.

 

AWS FinSpace Interview Questions and Answers

AWS MSK Interview Questions and Answers

 

Ques. 20):  What's the difference between removing my container service and halting it?

Answer:

Your container nodes are in a disabled state when you disable your container service, and the public endpoint of the service returns an HTTP status code of '503'. The service returns to the most recent active deployment when it is enabled. Configurations for power and scalability are also kept. Following re-enabling, the public endpoint's name remains unchanged. Container images and deployment history are kept.

You are acting destructively when you remove your container service. All of the service's container nodes will be permanently destroyed. Additionally, your service's container images, deployment history, logs, and HTTPS public endpoint address will all be permanently erased. It is impossible for you to get the endpoint address back.

Ques. 13): How should I think about when to use AWS Wavelength, AWS Local Zones, or AWS Outposts for applications requiring low latency or local data processing?

Answer:

Wherever they are deployed, AWS assists customers in providing a consistent experience to serve applications with low latency requirements or local data processing needs.

By extending AWS infrastructure, services, APIs, and tools to 5G networks, AWS Wavelength is intended to enable ultra-low latency applications to 5G devices. In order to assist developers in creating new applications for 5G end users needing single-digit millisecond latency, such as IoT devices, game streaming, autonomous cars, and live video creation, Wavelength embeds storage and computing into telecom providers' 5G networks.

AWS Local Zones are a new kind of AWS infrastructure created to handle workloads that need single-digit millisecond latency in more places, such as virtual desktop apps with heavy graphics. Some customers may not want to manage their own on-site data centre, while others could choose to completely do away with their nearby data centre. Customers may benefit from operating computing and storage resources closer to end users by using Local Zones without having to own and manage their own data centre infrastructure.

In order to function smoothly alongside customers' AWS workloads, AWS Outposts is made for workloads that must remain on-premises owing to latency limitations. AWS Outposts are fully managed and configurable compute and storage racks built with AWS-designed hardware, which allows customers to run compute and storage on-premises while seamlessly connecting to AWS’s broad array of cloud services.

Top 20 AWS X-Ray Interview Questions and Answers

 

 

Ques. 1): Describe AWS X-Ray.

Answer:

AWS X-Ray aids programmers in the analysis and debugging of distributed, in-use systems like those created with a microservices architecture. In order to pinpoint and resolve the underlying causes of performance problems and failures, you may utilise X-Ray to understand how your application and its supporting services are operating. X-Ray displays a map of the underlying components of your application and offers an end-to-end view of requests as they go through it. From straightforward three-tier apps to intricate microservices projects with thousands of services, you can use X-Ray to examine programmes both in development and in production.

AWS Cloud Interview Questions and Answers

 

Ques. 2): How do traces work?

Answer:

A collection of data points with the same trace ID is referred to as an X-Ray trace. For instance, a client's request for your application receives a special trace ID. Through the use of this particular trace ID, the services in your application that handle the request communicate details about it back to X-Ray. A segment is the information that each service in your application sends to X-Ray, and a trace is a group of segments.

 

AWS AppSync Interview Questions and Answers

AWS Cloud9 Interview Questions and Answers

 

Ques. 3): What AWS services are compatible with X-Ray?

Answer:

Applications running on EC2, ECS, Lambda, Amazon SQS, Amazon SNS, and Elastic Beanstalk are compatible with X-Ray. Additionally, when an API request is performed to an AWS service using the AWS SDK, the X-Ray SDK automatically records the information. The X-Ray SDK also offers add-ons for the PostgreSQL and MySQL drivers.

 

Amazon Athena Interview Questions and Answers

AWS RedShift Interview Questions and Answers

 

Ques. 4): Can I use X-Ray to track requests coming from services or apps that are distributed across several regions?

Answer:

Yes, you may use X-Ray to follow requests as they move between apps or services in different regions. The processed region's local copy of the X-ray data is kept, but it contains enough details for client programmes to aggregate it and present a global picture of the traces. AWS services will automatically include region annotation; however, in order to enable cross-region functionality, clients must instrument bespoke services to add the regional annotation.


AWS Cloud Practitioner Essentials Questions and Answers

AWS EC2 Interview Questions and Answers

 

Ques. 5): Why do I occasionally only see traces in part?

Answer:

The utmost effort is made by X-Ray to provide comprehensive trace information. However, it is likely that the trace information supplied by the X-Ray APIs will only be partial in some circumstances (connectivity problems, a delay in receiving segments, etc.). When this occurs, X-Ray labels the traces as partial or incomplete.


AWS Lambda Interview Questions and Answers

AWS Cloud Security Interview Questions and Answers


Ques. 6): Why ought I to employ X-Ray? 

Answer:

To manage requests for your application as they move between different components that make up your application, you currently have to rely on a per-service or per-resource process if you create and execute distributed applications. The many log formats and storage media used by the frameworks, services, and resources that your application consumes or operates on add to the complexity of this issue. Due to this, it is challenging to connect the many bits of information and build a complete picture of a request from the point at which it originates at the end user or service to the point at which a response is delivered by your application. Instead of using a service- or resource-centric approach to track requests made to your application, X-Ray uses a user-centric model. This model enables you to create a user-centric picture of requests as they travel across services and resources. By correlating and aggregating data on your behalf, X-Ray enables you to focus on improving the experience for end-users of your application.


AWS Simple Storage Service (S3) Interview Questions and Answers

AWS Fargate Interview Questions and Answers

 

Ques. 7): Describe a segment.

Answer:

Each data point for a single distributed application component, such the authorisation service, is included in an X-Ray segment. Segments are made up of one or more sub-segments that reflect the remote calls made from the service and contain system-defined and user-defined data in the form of annotations. As an instance, when your application responds to a request by calling a database, it produces a segment for that request and a sub-segment to represent the database call and its outcome. Data like the query, table utilised, date, and error status can be included in the sub-segment.

 

AWS SageMaker Interview Questions and Answers

AWS DynamoDB Interview Questions and Answers

 

Ques. 8): What is an annotation?

Answer:

System-defined or user-defined information connected to a segment is an X-Ray annotation. An annotation may appear more than once in a section. User-defined annotations are metadata that developers contribute to segments, and system-defined annotations are data that AWS services add to the segment. For calls to AWS services, for instance, a segment formed by your application can be automatically injected with region data; however, for connections to non-AWS services, you may opt to manually provide region data.


AWS Cloudwatch interview Questions and Answers

AWS Elastic Block Store (EBS) Interview Questions and Answers

 

Ques. 9): What are errors?

Answer:

System annotations known as X-Ray errors are attached to a segment for a call that receives an error response. The error contains the error message, stack trace, and any other details (such as the version or commit ID) that help link the error to a specific source file.


AWS Amplify Interview Questions and Answers

AWS Secrets Manager Interview Questions and Answers

 

Ques. 10): What can I use X-Ray for?

Answer:

Create a service map - By monitoring the requests made to your apps, X-Ray can map the services that are utilised by your application. This gives you a picture of the relationships between the services in your application and makes it possible for you to build a dependency tree, identify services that aren't performing as intended, discover delay or issues while working across AWS Availability Zones or Regions, and more.

Finding faults and problems in your application code is easy with X-Ray since it examines the response code for each request made to your application. This makes it simple to debug application code without having to manually replicate errors or bugs.

Build your own analysis and visualization apps – X-Ray provides a set of query APIs you can use to build your own analysis and visualizations apps that use the data that X-Ray records.


AWS Django Interview Questions and Answers

AWS Cloud Support Engineer Interview Question and Answers

 

Ques. 11): Does X-Ray provide an API?

Answer:

Yes, X-Ray offers a collection of APIs for ingesting request data, tracing queries, and service configuration. In addition to the X-Ray apps already available, you may create your own analysis and visualisation programmes using the X-Ray API.


AWS Solution Architect Interview Questions and Answers

AWS Glue Interview Questions and Answers

 

Ques. 12): What is sampling?

Answer:

When making requests to an application, X-Ray does not always gather data in order to deliver a performant and economical experience. Instead, it gathers information for a sizable enough sample of queries. Because X-Ray cannot ensure data completeness, it should not be utilised as an audit or compliance tool.

Ques. 13): What modifications to my application's code must I make in order to use X-Ray?

Answer:

You must integrate the language-specific X-Ray libraries into your application code if you're utilising Elastic Beanstalk. You must install the X-Ray agent and instrument your application code for applications running on other AWS services, such as EC2 or ECS.

 

AWS DevOps Cloud Interview Questions and Answers

AWS Aurora Interview Questions and Answers

 

Ques. 14): The X-Ray agent: What is it?

Answer:

Data from log files are gathered by the X-Ray agent and sent to the X-Ray service for aggregation, analysis, and storage. Instead of utilising the APIs directly, the agent simplifies the process of sending data to the X-Ray service and is compatible with Windows Server 2012 R2 or later, Red Hat Enterprise Linux (RHEL), and Amazon Linux AMI.
