Question #: 37
Topic #: 1

A company is implementing a new ESXi host cluster at its New York data center.
✑ The CIO has stated that the new ESXi cluster should be designed with enough failover capacity to sustain two ESXi host failures.
✑ Six ESXi hosts have been approved for this workload.
✑ The ESXi hosts are to be purchased from Dell with these specifications.
✑ 2x10 core 2.2GHz Intel CPU
✑ 128 GB of memory
✑ The workload is defined as 150 employee desktop virtual machines each with 3GB RAM reserves.
All virtual machines should be protected by vSphere High Availability.

Which are two true statements regarding failover capacity? (Choose two.)

A. vSphere HA can be configured to reserve 25% of memory capacity for failover.
B. vSphere HA can be configured to specify two dedicated failover hosts.
C. vSphere HA can be configured to reserve 35% of memory capacity for failover.
D. vSphere HA can be configured to specify one dedicated failover host.

Agreed with provided answer. Technically ,I'd be setting the reserve to 33% or setting Admission Control to compensate for up to 2x host failures.

I believe these options don't take into account memory overhead. Besides if BC are correct, alsa AD are correct, because if it is trute that you can reserve 35% and 35 > 25, also 25% is truse. Same for 2 hosts availabe sinve 2 > 1. For these reasons I would go for AD

In the question it is stated the following "The CIO has stated that the new ESXi cluster should be designed with enough failover capacity to sustain two ESXi host failures" If you do the math properly, you need to have 2 hosts in standby in order to cover for the failure of 2 hosts, or to reserve 331/3% which is more than 25%.

Why 35% and not 25%?

Math 101 I guess ;) the RAM of 2 hosts is 256gb. What percentage is that of the total RAM available... 1/3 or 33 1/3%
