Question 1

What is a subnet in Amazon VPC?

Accepted Answer

A range of IP addresses within a VPC that resources are placed into, tied to a specific Availability Zone

Answer

A subnet is a range of IP addresses in your VPC that spans a single Availability Zone, allowing you to place groups of isolated resources and control routing and access.

Question 2

Which Route 53 routing policy would you use to route traffic based on the lowest network latency for end users?

Accepted Answer

Latency-based routing

Answer

Latency-based routing directs traffic to the AWS Region that provides the lowest latency for the end user, improving application performance for globally distributed users.

Question 3

What is AWS Transit Gateway?

Accepted Answer

A managed service that connects VPCs and on-premises networks through a central hub, simplifying the network topology

Answer

AWS Transit Gateway acts as a cloud router and central hub to connect multiple VPCs and on-premises networks, replacing complex peering arrangements with a simpler hub-and-spoke model.

Question 4

What is the difference between a public subnet and a private subnet in a VPC?

Accepted Answer

Public subnets have a route to an Internet Gateway allowing direct internet access, while private subnets do not

Answer

A public subnet has a route table entry directing internet-bound traffic to an Internet Gateway, making resources directly reachable from the internet, while a private subnet has no such route.

Question 5

In Amazon CloudFront, what is an 'origin'?

Accepted Answer

The server or AWS service (such as S3 or an ALB) where CloudFront fetches content to cache and distribute

Answer

In CloudFront, an origin is the definitive source of content — such as an S3 bucket, an Application Load Balancer, or a custom HTTP server — from which CloudFront retrieves content to cache at edge locations.
