A customer has six hosts available in a cluster. When running at full capacity, all virtual machines can be run on two hosts.
How many hosts can the customer place into maintenance mode at the same time while still providing N+2 resiliency to the cluster?
To ensure N+2 resiliency in a cluster with six hosts, you need to have two hosts handling the current virtual machine load and another two hosts available for failover, which accounts for a total of four hosts. This leaves two hosts that can be placed into maintenance mode at any given time without compromising the required N+2 resiliency.
A for sure! 2 Hosts to hold the running VM at full capacity 2 As resiliency N+2 2 In maintenance mode
Isn't it A= 2 ? 2 with VMs + 2 In maintenance mode + 2 as resiliency (N+2)
Shall be A
A is correct
Not sure why all answered are incorrect in this dump.
To make discussions about each question and answer. That is my view.
A is correct
Answer is A (2)
A. 6 - 2 = 4 N+2=4 N=4-2 N=2 easy math
well guys this is a tricky question, I think when he said "at the same time" it matter here, we've got : 2Host for VM load, when will put 2 host in the same Time in MM this n+1==> which Mean for n+2 it will Left None
Correcting my answer to A= 2 hosts
Answer is A of course.
IT is C. It states N+2 resiliency as a requirement: 2 hosts for the running load + 2 more. There will remain two hosts: from which one can be put in maintenance mode. while the other host remains available for a failover scenario (because the condition is to have N+2 all the time).
Why can't the customer put both remaining hosts in maintenance mode? The requirement is N+2. They need 2 hosts to run the workload, 2 for failover, that leaves 2 hosts with spare capacity. Imagine customer puts both hosts in maintenance mode, and loses the two production hosts it still leaves 2 hosts to run all the workload. Hence A is the right answer.
Do they mean the 2 hosts are at full capacity with no room, or do they mean they still provide HA (n+1) ? If the latter, then it would be 3 hosts - 1 to run the VMs and 2 for the N+2, which leaves 3 hosts able to put in MM.
