100-160 Question 79
Select 2A company is experiencing frequent network outages impacting its internal communication. As part of your investigation, you examine the network infrastructure and find that a single switch is being used to connect all devices in the network. Which of the following network technologies should be implemented to improve reliability and reduce single points of failure?
- A
Redundant switches connected in a loop-free topology
- B
A load balancer to distribute traffic across multiple servers
- C
Network segmentation using VLANs
- D
Implementing a firewall between the switch and the router
- E
Configuring Spanning Tree Protocol (STP)
Show answer and explanation
Correct answers: A, E
Explanation
To improve reliability and reduce single points of failure, redundant switches should be implemented to provide backup connectivity in case of a failure. Additionally, Spanning Tree Protocol (STP) must be configured to prevent network loops when multiple switches are interconnected. These measures ensure a more robust and fault-tolerant network infrastructure.
- A. Correct.
Redundant switches connected in a loop-free topology improve reliability by ensuring that if one switch fails, another can take over, thus reducing single points of failure.
- B. Incorrect.
A load balancer is used to distribute traffic across servers, which improves server availability rather than addressing single points of failure in the network infrastructure.
- C. Incorrect.
Network segmentation using VLANs improves security and performance but does not address the issue of single points of failure in the network infrastructure.
- D. Incorrect.
A firewall enhances security by filtering traffic but does not address the reliability of the network infrastructure or single points of failure.
- E. Correct.
Configuring Spanning Tree Protocol (STP) prevents network loops when redundant switches are introduced, ensuring a stable and loop-free topology.
