Top 20 AWS Transit Gateway Interview Questions and Answers


AWS Transit Gateway is a central hub that links your Amazon Virtual Private Clouds (VPCs) and on-premises networks. This streamlines your network and eliminates complicated peering arrangements. It functions as a cloud router, establishing new connections only once.

AWS(Amazon Web Services) Interview Questions and Answers

Ques. 1): How do I decide which Amazon Virtual Private Clouds (VPCs) are allowed to speak with one another?


Create numerous route tables in an AWS Transit Gateway and attach Amazon VPCs and VPNs to them to partition your network. This allows you to construct isolated networks within an AWS Transit Gateway, similar to how VRFs are used in traditional networks. There will be a default route table for the AWS Transit Gateway. Multiple route tables can be used if desired.

AWS SageMaker Interview Questions and Answers

Ques. 13): What is the process for propagating routes into the AWS Transit Gateway?


In the AWS Transit Gateway, routes are propagated in two ways:

Propagation of routes to/from on-premises networks: Routes will propagate between the AWS Transit Gateway and your on-premises router utilising Border Gateway Protocol when you connect VPN or Direct Connect Gateway (BGP).

Routes to/from Amazon VPCs: When you attach or resize an Amazon VPC to an AWS Transit Gateway, the Amazon VPC Classless Inter-Domain Routing (CIDR) will propagate into the AWS Transit Gateway route table utilising internal APIs (not BGP). CIDR is a technique of allocating IP addresses and IP routing that helps to reduce the expansion of routing tables on routers throughout the Internet and the quick expiration of IPv4 addresses. The Amazon VPC's route table will not receive routes from the AWS Transit Gateway route table. To transmit traffic to the AWS Transit Gateway, the VPC owner must construct a static route.

Route propagation is not supported via peering links between Transit Gateways. To send traffic on peering attachments, you must construct static routes in the Transit gateway route tables.

AWS DynamoDB Interview Questions and Answers

Ques. 14): AWS Transit Gateway complies with which compliance programmes?


AWS Transit Gateway inherits Amazon VPC compliance and fulfils PCI DSS Level 1, ISO 9001, ISO 27001, ISO 27017, ISO 27018, SOC 1, SOC 2, SOC 3, FedRAMP Moderate, FedRAMP High, and HIPAA compliance requirements.

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?


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: -


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.


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?


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? 


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?


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?


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?


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?


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?


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?


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.
