Practice Test 1 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
You are creating a new architecture for a financial firm. The architecture consists of some EC2 instances with the same type and size (M5.large). In this architecture, all the EC2 mostly communicate with each other. Business people have asked you to create this architecture keeping in mind low latency as a priority. Which placement group option could you suggest for the instances?
A. Partition Placement Group
B. Clustered Placement Group
C. Spread Placement Group
D. Enhanced Networking Placement Group
Explanation:
Answer: B
- Option A is incorrect. Partition Placement Groups distribute the instances in different partitions. The partitions are placed in the same AZ, but do not share the same rack. This type of placement group does not provide low latency throughput to the instances. More details-

- Option B is CORRECT. Clustered Placement Group places all the instances on the same rack. This placement group option provides 10 Gbps connectivity between instances ( Internet connectivity in the instances has a maximum of 5 Gbps). This option of placement group is perfect for the workload that needs low latency. More details-
