CompTIA Network+ (N10-008) — Question 179

A user reports that a new VoIP phone works properly, but the computer that is connected to the phone cannot access any network resources. Which of the following MOST likely needs to be configured correctly to provide network connectivity to the computer?

Answer options

• A. Port duplex settings
• B. Port aggregation
• C. ARP settings
• D. VLAN tags
• E. MDIX settings

Correct answer: D

Explanation

The most likely issue is related to VLAN tags, as the VoIP phone may be configured to place the computer in a separate VLAN for voice traffic. If VLAN tagging is not properly set, the computer will not be able to communicate on the network. The other options do not directly relate to the issue of network connectivity for the computer in this scenario.
