CompTIA CNX-001 Exam - Topic 3 Question 11 Discussion

Actual exam question for CompTIA's CNX-001 exam

Question #: 11
Topic #: 3

A company is expanding its network and needs to ensure improved stability and reliability. The proposed solution must fulfill the following requirements:

Detection and prevention of network loops

Automatic configuration of ports

Standard protocol (not proprietary)

Which of the following protocols is the most appropriate?

ASTP

BSIP

CRTSP

DBGP

Show Suggested Answer

Suggested Answer: A

The Spanning Tree Protocol (IEEE 802.1D) is a non-proprietary standard that automatically detects Layer 2 loops and dynamically places redundant switch ports into a blocking or forwarding state, ensuring loop prevention and automatic port configuration.

BGP is for routing, not for loop prevention. STP is clear.

I thought SIP was for voice communication, not networks.

Wait, isn't BGP more for routing?

BGP? Really? That's like trying to put a square peg in a round hole.

STP is the obvious answer. Anything else would be a real loop-de-loop.

I feel like STP is the most appropriate here, but I wonder if there are any other protocols that could also fit the requirements.

I’m a bit confused because I thought BGP was for routing, not for loop prevention. Is STP definitely the standard protocol we need?

I remember practicing a question about network protocols, and STP was mentioned as a standard one for loop prevention.

I think STP might be the right choice since it’s designed to prevent loops in the network, but I’m not completely sure.

I think I've got this one figured out. STP is the Spanning Tree Protocol, which is designed to prevent network loops. It also supports automatic port configuration, and it's a standard protocol. Yep, I'm pretty confident STP is the right answer here.

Alright, I've got a plan. I'll start by ruling out SIP and RTSP since they don't seem to match the requirements. Then I'll compare STP and BGP more closely to see which one is the best fit.

Ugh, network protocols are not my strong suit. I'm a bit lost on this one. Maybe I'll try to eliminate the options that clearly don't fit the requirements first.

SIP and RTSP are not suitable here. They don't handle loops.

Okay, let's see. The key things I'm looking for are loop prevention, auto-config, and a standard protocol. I think STP might be the way to go, but I'll double-check the other options just to be sure.

Hmm, this seems like a straightforward network protocol question. I'll need to carefully review the requirements and think through the pros and cons of each option.
