VCP-DCV vSphere Performance and Scaling Practice Question

Exhibit

Refer to the exhibit.

Memory section from resxtop:
  MCTLSZ   MEMSZ    SWCUR    SWR/s    SWW/s
    0.0    4096     512      10       5

Based on the exhibit, which statement about the virtual machine's memory state is TRUE?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The VM is actively swapping memory because of memory pressure.

SWCUR (current swapped memory) is 512 MB, and SWR/s and SWW/s show non-zero swap rates, indicating that the VM is actively swapping memory to disk. MCTLSZ is 0, meaning no ballooning is occurring. The VM's memory size is 4096 MB. Swapping is a sign of memory pressure.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The VM is using the memory balloon driver to reclaim memory.
Why it's wrong here
MCTLSZ is 0, so the balloon driver is not reclaiming memory.
✗
The VM is using transparent page sharing to reduce memory usage.
Why it's wrong here
Transparent page sharing is not shown in this exhibit; it would appear under other metrics.
✗
The VM has no memory pressure and is performing optimally.
Why it's wrong here
Swapping indicates memory pressure and poor performance.
✓
The VM is actively swapping memory because of memory pressure.
Why this is correct
SWCUR and swap rates confirm swapping is occurring.
