CompTIA Network+ (N10-008) — Question 444

A network technician is deploying multiple switches for a new office. The switches are separately managed and need to be cabled in to support dual firewalls in a HA setup. Which of the following should the technician enable to support proper stability of the network switches?

Answer options

• A. NTP
• B. CDMA
• C. STP
• D. LACP
• E. 802.1Q

Correct answer: C

Explanation

The correct answer is STP (Spanning Tree Protocol), which prevents loops in the network topology and ensures stability among the switches. NTP is for time synchronization, CDMA is a communication protocol, LACP is for link aggregation, and 802.1Q is for VLAN tagging, none of which specifically address the issue of preventing network loops.
