CompTIA Network+ (N10-008) — Question 525

A company’s VoIP phone connection is cutting in and out. Which of the following should be configured to resolve this issue?

Answer options

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

Correct answer: A

Explanation

Configuring 802.1Q tagging is essential for ensuring that VoIP traffic is properly prioritized and maintained across VLANs, which can help prevent interruptions. The other options, such as Jumbo frames, Native VLAN, and Link aggregation, do not directly address the need for traffic prioritization for VoIP applications, making them less effective for resolving this specific issue.
