Oracle GoldenGate 12c Implementation Essentials — Question 1

A customer decides to use 2 large servers to load balance a mix of large and small virtual machines. Each server has 64GB of RAM and 8 quad-core CPUs. There are 14 virtual machines, 6 of which use 12GB of virtual memory and 16 vCPU each, and the remaining 8 use 2GB and 4 vCPUs each. What two issues will the customer likely discover when one of the servers fails?

Answer options

• A. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of vCPUs.
• B. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of memory.
• C. Live migration will be unavailable until the second server is restored.
• D. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of vNICs.
• E. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of shared storage.

Correct answer: A

Explanation

The correct answer is A, as the remaining server does not have enough vCPUs to accommodate all the large virtual machines that require 16 vCPUs each. Option B is incorrect because there is sufficient memory available on the second server to handle the smaller VMs. The other options (C, D, E) do not relate to the immediate resource constraints caused by the server failure in this particular scenario.
