Designing Cisco Data Center Infrastructure (DCID) — Question 78

An engineer must design a Cisco HyperFlex solution to support a virtualized environment in a single data center location. The design must consider these customer requirements:

• a large-scale cluster with eight or more nodes
• distributed high-performance file system for virtualized servers
• high fault tolerance to multiple node failures

Which action meets these objectives?

Answer options

• A. Configure data destaging and deduplication.
• B. Implement a replication factor of four.
• C. Enable logical availability zones.
• D. Create multiple datastores for storage of VM.

Correct answer: C

Explanation

Enabling logical availability zones helps to achieve high fault tolerance by isolating nodes into zones, which allows for continued operation even if multiple nodes fail. The other options, such as configuring data destaging and deduplication, establishing a replication factor, or creating multiple datastores, do not directly address the requirement for fault tolerance or the architecture of a large-scale cluster.
