CompTIA Network+ (N10-009) — Question 434

A company's VoIP phone connection is cutting in and out. A senior network engineer is recommending the implementation of a voice VLAN. Which of the following should be configured?

Answer options

• A. 802.1Q tagging
• B. Jumbo frames
• C. Native VLAN
• D. Link aggregation

Correct answer: A

Explanation

The correct answer is A, 802.1Q tagging, as it is necessary for distinguishing voice traffic on a separate VLAN, ensuring better quality and prioritization of VoIP calls. The other options, such as Jumbo frames, Native VLAN, and Link aggregation, do not directly address the need for separating voice traffic from other data traffic, which is essential for maintaining call quality.
