A virtual machine is slow, and the memory assigned to it is far below what its application needs. The host still has free memory. Which change fits?
Select an answer to reveal the explanation.
Short Explanation
The guest was given a tiny desk in a building that still has empty rooms. You assign it more memory. A faster screen, a port-test plug, and a disk stripe do not hand the guest more RAM.
Full Explanation
A guest can use only the memory the hypervisor assigns to it. This guest is far below what its application needs, and the host has free memory, so assigning more memory to the guest is the change. Refresh rate is a display setting. It does not add RAM to a virtual machine. A loopback plug tests a network port. It does not change a memory assignment. RAID 0 stripes disks. It does not turn disk space into guest RAM. Exam caveat: do not assign so much that the host itself starts swapping. Leave the host enough memory to run. Operational check: raise the guest's memory, boot it, and confirm the application stays responsive while the host still has free memory. Raise the guest's memory, boot it, and confirm the host still has memory free. Record the result on the ticket before you close the call. Do not give the guest so much memory that the host starts paging.
