  A. Pool 1 - SSD and SAS drives with storage tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - SAS and NL SAS drives with storage tiering and cache tiering

  B. Pool 1 - SSD and SAS drives with storage tieringPool 2 - SSD and NL SAS drives with storage tieringPool 3 - SAS drives with cache tiering

  C. Pool 1 - SSD and SAS drives with storage tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - NL SAS drives with cache tiering

  D. Pool 1 - SSD and SAS drives with storage tiering and cache tieringPool 2 - SAS and NL SAS drives with storage tiering and cache tieringPool 3 - NL SAS drives with cache tiering

  Correct Answer: C

• Question 196:

  Which is a valid method for modifying an application environment to support more clients and increased data throughput?

  B. Migrate the application from SSD to SAS storage

  C. Vertically scale by adding more nodes to support the application

  D. Horizontally scale by increasing system resources on the same number of nodes

  Correct Answer: A

• Question 197:

  You are planning to deploy a virtualized application in a high-availability configuration with automated VM restart on a hypervisor cluster. Your sizing estimates show that peak workload conditions will saturate the processing power of three hypervisor servers.

  To meet the SLA, N+2 redundancy is required on the hypervisor servers, with server utilization not to exceed 75% under any conditions.

  What is the minimum number of nodes that you should configure in the hypervisor cluster?

  A. 5

  B. 6

  C. 7

  D. 8

  Correct Answer: B
