Sample Questions
Question:
A company is deploying an application on AWS that requires low-latency communication between EC2 instances. The application consists of multiple microservices running in separate Amazon VPCs. Which AWS service should the company use to achieve low-latency communication between these VPCs?
A) Amazon VPC peering
B) AWS Direct Connect
C) Amazon CloudFront
D) Amazon Route 53
Explanation:
Correct Answer: A) Amazon VPC peering
VPC peering allows direct communication between VPCs within the same AWS region. It operates at the network layer (Layer 3) and provides low-latency connectivity.
VPC peering does not support transitive routing, meaning traffic cannot flow through a peered VPC to reach another VPC.
B) AWS Direct Connect
AWS Direct Connect provides dedicated network connections between on-premises data centers and AWS. While it ensures reliable and consistent performance, it is not designed for low-latency communication between VPCs.
C) Amazon CloudFront
Amazon CloudFront is a content delivery network (CDN) service that accelerates content delivery by caching data at edge locations. It is not suitable for direct VPC-to-VPC communication.
D) Amazon Route 53
Amazon Route 53 is a managed DNS service and does not provide low-latency communication between VPCs.
Question:
A company is deploying a highly available web application on AWS. The application consists of multiple EC2 instances distributed across different Availability Zones (AZs). The company wants to ensure that if an AZ becomes unavailable, traffic is automatically rerouted to healthy instances in other AZs. Which AWS service should the company use to achieve this?
A) Amazon Route 53
B) Amazon CloudFront
C) Amazon Elastic Load Balancer (ELB)
D) Amazon VPC peering
Explanation:
Correct Answer: C) Amazon Elastic Load Balancer (ELB)
Amazon ELB (specifically, the Application Load Balancer or Network Load Balancer) automatically distributes incoming traffic across multiple healthy instances in different AZs.
If an AZ becomes unavailable, ELB reroutes traffic to healthy instances in other AZs, ensuring high availability.
A) Amazon Route 53
Amazon Route 53 is a DNS service and can route traffic based on health checks, but it does not automatically handle instance failover.
B) Amazon CloudFront
Amazon CloudFront is a content delivery network (CDN) and does not provide automatic failover between instances.
D) Amazon VPC peering
VPC peering connects VPCs within the same region but does not handle load balancing or failover.
