Your team is planning to create a set of instances in a VPC. They need to ensure high network performance for the underlying instances and enhanced communication between the instances. Which of the following steps would you take? Choose 2 answers from the options given below.

Answer options:

A.Enable Enhanced Networking for the underlying Instances.
B.Set the MTU for the Instances to 1500.
C.Create the Instances in separate Availability Zones and put them in a cluster placement Group.
D.Create the Instances in the same Availability Zones and put them in a cluster placement group.

Answer – A and D
The AWS Documentation mentions the following.
A cluster placement group is a logical grouping of instances within a single Availability Zone. Placement groups are recommended for applications that benefit from low network latency, high network throughput, or both. 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 B is invalid because this is the default MTU available.
Option C is invalid because the instances need to be in the same available zone for being part of a placement group.
