This VCP-DCV practice question tests your understanding of vsphere lifecycle management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a vLCM remediation, one host fails with error 'Could not complete the operation due to a network error'. What is the first troubleshooting step?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Reset the vLCM image.
Why wrong: Resetting the image is unrelated to network errors.
Check network connectivity between vCenter and the host.
Network errors indicate connectivity issues; checking ping/traceroute is logical first step.
Restart the vLCM service.
Why wrong: Restarting the service may not resolve a network issue.
Reboot the host.
Why wrong: Rebooting does not fix network connectivity.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Check network connectivity between vCenter and the host.
Option B is correct because network connectivity between vCenter and the host is essential for remediation. Option A restarts service but masks the issue; Option C reboots the host unnecessarily; Option D resets image but doesn't address the root cause.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Reset the vLCM image.
Why it's wrong here
Resetting the image is unrelated to network errors.
Check network connectivity between vCenter and the host.
Why this is correct
Network errors indicate connectivity issues; checking ping/traceroute is logical first step.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
CIDR notation defines the prefix length.
Restart the vLCM service.
Why it's wrong here
Restarting the service may not resolve a network issue.
Reboot the host.
Why it's wrong here
Rebooting does not fix network connectivity.
Common exam traps
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related VCP-DCV subnetting questions on CIDR, address ranges, and subnet selection.
