CompTIA Server+ (SK0-005) — Question 338

A server administrator is completing an OS installation for a new server. The administrator patches the server with the latest vendor-suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity. Which of the following is the MOST likely reason for the lack of connectivity?

Answer options

• A. The VLAN is improperly configured.
• B. The DNS configuration is invalid.
• C. The OS version is not compatible with the network switch vendor.
• D. The HIDS is preventing the connection.

Correct answer: A

Explanation

The most likely cause of the lack of connectivity is an improper VLAN configuration, as VLAN settings determine the network segment the server is on. While invalid DNS settings and OS version incompatibility could cause issues later, they wouldn't prevent initial network access. HIDS could potentially block traffic, but it's less common than VLAN misconfigurations in new setups.
