VCP-VVF Deploy Configure And Operate Vvf Practice Question
An administrator is replacing default VMCA-signed certificates with custom Certificate Authority (CA) signed certificates on a vCenter 9.0 instance using the vSphere Certificate Manager utility. During the process, the utility fails while generating the Certificate Signing Request (CSR). What is the primary cause of this 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
✓
The configuration file (certool.cfg) contains incorrect or missing mandatory parameters.
The certificate manager utility relies on the configuration values defined in the certool.cfg file. Incorrect parameters or special characters in fields such as organization, locality, or country code will cause the CSR generation to fail.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Port 443 is blocked by a local firewall on the ESXi management vmkernel interface.
Why it's wrong here
Certificate generation and CSR creation are local processes on the vCenter appliance and do not rely on ESXi firewall rules.
- ✗
The root CA certificate has expired on the external enterprise CA server.
Why it's wrong here
An expired root CA causes signing failures, not local CSR generation failures within the certool utility.
- ✓
The configuration file (certool.cfg) contains incorrect or missing mandatory parameters.
Why this is correct
certool.cfg must be properly populated with organization details before generating the CSR.
- ✗
The vCenter Appliance Management Interface (VAMI) service is stopped.
Why it's wrong here
vSphere Certificate Manager runs via SSH/CLI on the vCenter appliance and does not require the VAMI web service to be running.
