CompTIA Network+ (N10-007) — Question 641

Company A has leased a second office located two floors below its main office. Company B is located on the floor in between Company A's office and is performing research on electromagnetic fields. The core switch at the MDF is connected to the switch at the IDF with a 131ft (40m) Cat 6 UTP cable. Both gigabit switches support Cat 7a and have SFP ports available. Company A's second office has reported intermittent issues with slow and sometimes dropped connections to the main office network. Which of the following steps will MOST likely resolve the connectivity issues? (Choose two.)

Answer options

• A. Connect the switches using an 802.11ac bridge.
• B. Connect the switches with a fiber cable via SFP.
• C. Connect the switches with a Cat 6 STP cable.
• D. Connect the switches with a Cat 7a UTP cable.
• E. Connect the switches using a plenum-rated Cat 7a UTP cable.
• F. Connect the switches using a gigabit powerline adapter.

Correct answer: B, C

Explanation

Connecting the switches with a fiber cable via SFP (Option B) provides a higher bandwidth and eliminates electromagnetic interference, addressing the connectivity issues. While using a Cat 6 STP cable (Option C) can reduce interference compared to UTP, it may not offer the same performance benefits as fiber, making B the superior choice. The other options do not sufficiently address the issues or may introduce additional complications.
