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.)
Deploy memory-optimized EC2 instances in a cluster placement group.
Deploy memory-optimized EC2 instances in a spread placement group.
Connect the EC2 instances to an Amazon FSx for Lustre file system.
Connect the EC2 instances to an Amazon FSx for Windows File Server file system.
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
