VCP-VVF Deploy Configure And Operate Vvf Practice Question
An administrator is deploying VMware vSphere Foundation 9.0 using the Cloud Builder appliance. During the environment bring-up validation phase, the precheck fails due to an insufficient number of IP addresses assigned to the ESXi management network pool. Which action must the administrator take to resolve this validation failure?
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
✓
Modify the JSON specification file to expand the IP address pool range with valid unused IP addresses and restart prechecks.
The Cloud Builder deployment requires a specific contiguous block of IP addresses for ESXi management, vCenter, NSX, and SDDC Manager components depending on the scale. The administrator must add valid, unused IP addresses to the IP pool configuration file or JSON specification and re-run the prechecks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reboot the Cloud Builder appliance to clear cached allocation tables from previous failed validation runs.
Why it's wrong here
Rebooting does not resolve an actual lack of available IP addresses within the defined network segment.
- ✗
Bypass the IP validation phase by editing the Cloud Builder local deployment service configuration properties.
Why it's wrong here
Bypassing precheck validations is not supported and will lead to failures during the automated deployment phase.
- ✗
Deploy an external DHCP server on the management VLAN to dynamically lease addresses to the ESXi hosts.
Why it's wrong here
VMware Cloud Builder requires static IP addressing for core infrastructure components during deployment.
- ✓
Modify the JSON specification file to expand the IP address pool range with valid unused IP addresses and restart prechecks.
Why this is correct
The JSON input file defines the IP allocation; correcting the range allows Cloud Builder prechecks to pass.
