Question #1677

A company is migrating its real-time analytics workloads, which require low-latency access to shared storage, from an on-premises environment to AWS. The company needs a cloud solution that supports both NFS and SMB protocols while minimizing latency for its compute instances. Which architecture should the company implement to meet these requirements? (Choose two.)

A

Deploy memory-optimized EC2 instances in a cluster placement group.

B

Deploy memory-optimized EC2 instances in a spread placement group.

C

Connect the EC2 instances to an Amazon FSx for Lustre file system.

D

Connect the EC2 instances to an Amazon FSx for Windows File Server file system.

E

Connect the EC2 instances to an Amazon FSx for NetApp ONTAP file system.

Explanation

The company requires low-latency access to shared storage supporting NFS and SMB.

- A: Cluster placement groups place instances in the same AZ with high-speed connectivity, reducing latency for real-time workloads. Memory-optimized instances are ideal for analytics.
- E: Amazon FSx for NetApp ONTAP natively supports both NFS and SMB protocols, providing flexible shared storage.

Other options:
- B: Spread placement groups reduce failure risk but increase latency, unsuitable for low-latency needs.
- C: FSx for Lustre is optimized for HPC but lacks native NFS/SMB support.
- D: FSx for Windows File Server supports SMB but not NFS.

Key Points:
1. Cluster placement groups minimize latency between EC2 instances.
2. FSx for NetApp ONTAP supports both required protocols.
3. Memory-optimized instances handle memory-intensive analytics workloads.

Answer

The correct answer is: AE
