CV0-003 Question #476: Real Exam Question with Answer & Explanation

The correct answer is C: IP address depletion. All 10 VMs appear in the dashboard because they were provisioned at the hypervisor/orchestration layer, but the last 2 cannot respond to pings because they were never assigned valid IP addresses. This happens when the subnet's available address pool is exhausted. For example, a /

Question

An administrator is using a script to create ten new VMs in a public cloud. The script runs and returns no errors. The administrator confirms that all ten VMs show up in the dashboard, but only the first eight reply to pings. Which of the following is the MOST likely cause of the issue?

Options

AWorkflow credential errors
BAPI request limitations
CIP address depletion
DBatch job scheduling issue

Explanation

All 10 VMs appear in the dashboard because they were provisioned at the hypervisor/orchestration layer, but the last 2 cannot respond to pings because they were never assigned valid IP addresses. This happens when the subnet's available address pool is exhausted. For example, a /29 subnet provides only 6 usable host addresses; a /28 provides 14. If the subnet only had 8 IPs remaining, the first 8 VMs get addresses and the last 2 do not, leaving them unreachable at the network layer. Workflow credential errors or API limits would typically cause the script to fail or error out, not silently produce partially functional VMs. Batch scheduling issues would not produce a clean 8-of-10 network split.
