CompTIA Network+ (N10-008) — Question 78

An engineer is configuring redundant network links between switches. Which of the following should the engineer enable to prevent network stability issues?

Answer options

• A. 802.1Q
• B. STP
• C. Flow control
• D. CSMA/CD

Correct answer: B

Explanation

The correct answer is B, STP (Spanning Tree Protocol), which helps prevent loops in a network by creating a tree structure that avoids redundancy issues. The other options do not directly address loop prevention: 802.1Q is for VLAN tagging, Flow control manages data transmission rates, and CSMA/CD is an access method used in Ethernet networks.
