Your company has a requirement for launching instances for an application. The instances need to have a low latency between them and have a high packet network performance. Which of the following would you do to ensure these requirements are met? Choose 2 answers from the options given below.

Answer options:

A.Create a cluster placement group grouping the instances in multiple availability zone.
B.Create a cluster placement group grouping the instances in a single availability zone.
C.Choose an GPU optimized Instance type for the underlying instance.
D.Choose an Instance type that supports Enhanced Networking for the underlying instance type.

Correct Answers: B and D
This is given in the AWS Documentation.
A cluster placement group is a logical grouping of instances within a single Availability Zone.
Cluster Placement groups are recommended for applications that benefit from low network latency, high network throughput, or both, if the majority of the network traffic is between the instances in the group. To provide the lowest latency and the highest packet-per-second network performance for your placement group, choose an instance type that supports enhanced networking.
Option A is incorrect since the instances need to be placed in a single Availability Zone.
Option C is incorrect this is used for graphic-intensive applications.
