Exam CV0-003 topic 1 question 62 discussion

Answer should be C. It is clearly hinted at in the question, and why would only 1 server be affected if it was a network driver issue.

A. Server unresponsiveness to remote login requests and absence of the server's IP address in the cloud management console—are consistent with a network interface issue. If the network driver updates failed to apply correctly, it could result in the network interface being in a down state, effectively rendering the server unreachable over the network. C. The server was assigned a new IP address, and the DNS entry for the server name was not updated. While plausible, the fact that DNS resolution correctly resolves the hostname to an IP address suggests that DNS is functioning correctly. If the server's IP address had changed, DNS resolution would likely fail. Additionally, DHCP typically handles DNS updates automatically, reducing the likelihood of a misconfigured DNS entry.

A. The network driver updates did not apply successfully, and the interface is in a down state. Based on the given information, the most likely cause of the server being unavailable is that the network driver updates did not apply successfully, and the interface is in a down state. The fact that the cloud management console does not show an IP address for the server suggests that the network interface is not functioning correctly. The fact that a DNS lookup shows the hostname resolving to an IP address indicates that DNS is working correctly, but the server is not responding to network requests.

Answer should be A. Question clearly states "The cloud management console does not show an IP address for that server."

I am going with A because the network drivers were just updated. I think the update failed on this server alone. Updating the drivers shouldn't cause DNS to assign a new IP address. Most if not all VMs I have seen in real-world have their IP addresses statically assigned.
