Which would be the best approach to meet their needs?

Refer to the exhibit.

You are expanding the compute layer of a VDC, and need to add more access layer switches to provide connectivity to the hypervisors. However, there are no available ports on the two aggregation layer switches to accommodate the uplink connections from the new access layer switches, and there is no available funding to purchase additional aggregation layer switches. The active uplinks are operating at 95% of capacity.

You are deploying a virtualized application in a high-availability configuration with automated VM restart on a hypervisor cluster. Your sizing estimates show that peak workloads will saturate the processing power of four hypervisor servers. To meet the SLA, N+2 redundancy is required on the hypervisor servers, with server utilization not to exceed 80% under any conditions.

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

Which two capacity management objectives often conflict with each other?

As part of a VDC deployment, you are examining the existing storage configurations. On one storage system, you discover over fifty storage pools. The pools contain a single type of drive (SSD, SAS or NL SAS), but many of them contain only a few drives and share the same RAID configuration. The Storage Administrator admits that they have been creating separate pools for each application because they did not want the applications contending for the disks.

As part of the design, you propose to consolidate the existing pools into larger pools of mixed drive types and RAID configurations.

What technology will you need to implement to utilize the new pool design?
