You have three Hyper-V hosts that each have 20 processor cores and 64 GB of RAM. Nine virtual machines
are deployed to the hosts as shown in the following table.
You plan to deploy a two-node Exchange Server 2016 database availability group (DAG)
by using the virtual machines. Each node will have 12 processor cores and 24 GB of
memory.
You are evaluating whether you can use the existing servers for the deployment or whether
you must purchase additional servers.
You need to recommend where to place the Exchange servers. The solution must minimize
costs.
What is the best recommendation to achieve the goal? More than one answer choice may
achieve the goal. Select the BEST answer.
A.
One Exchange server on Host1 and one Exchange server on a new Hyper-V host
B.
One Exchange server on Host1 and one Exchange server on Host3.
C.
Both Exchange servers on Host1.
D.
One Exchange server on Host1 and one Exchange server on Host2.
E.
One Exchange server on Host2 and one Exchange server on Host3
I don’t get this one. Shouldn’t it be A?
Hosts RAM CPU Cores Servers – RAM remaining Servers – CORES remaining
Host1 64 20 44 8
Host2 64 20 16 0
Host3 64 20 20 -12
This is what we have. By the looks of it:
1) Host1 has 44GB RAM available and 8 CPU cores
2) Host2 has 16GB RAM available and no CPU cores to spare
3) Host3 has 20GB RAM available and is over-provisioned by 12CPU cores
While we can add 1 Exchange Server to Host1, there’s no other suitable host that can hold the other server unless we play with migrating some VMs in hopes of balancing the resources better, which it will help much
Which I doubt it will help much*
Hosts RAM / CPU Cores / Servers – RAM remaining / Servers – CORES remaining
Host1 64 20 44 8
Host2 64 20 16 0
Host3 64 20 20 -12
^ a less confusing view of the table
Well I agree with you. While you can over-provision CPUs, you’re not allowed to give more RAM to virtual servers than what you totally have.
So the actual requirement is to have at least one host with enough RAM to handle some exchange server.
We have only Host1 and the only option from ABCDE which doesn’t exceed the RAM capacity is A
The correct is A or (missing answer: move 1 server from Host1 to Host2 and put both Exchange Servers on Host1)
Or REDUCE RAM of DC (who would require 8GB of ram on a DOMAIN CONTROLLER?) 🙂
Both Exchange servers on 1 host? I don’t like single points of failure 😉 I’d go with answer A.
Aligning with best practices would definitely exclude that option 🙂 you’re right
