100-160 Question 80
Select 3A company is experiencing frequent delays in accessing internal resources hosted on their on-premises servers. Upon inspection, the network team identifies that the issue stems from improper segmentation of the network infrastructure. Which of the following technologies or strategies would most effectively improve performance and enhance security?
- A
Implementing VLANs to segment network traffic
- B
Using a firewall to block all incoming traffic
- C
Deploying SD-WAN for optimized traffic routing
- D
Installing additional physical servers to reduce load
- E
Configuring ACLs (Access Control Lists) to restrict unauthorized access
Show answer and explanation
Correct answers: A, C, E
Explanation
To address the delays caused by improper network segmentation, VLANs and SD-WAN can optimize traffic flow and improve performance, while ACLs enhance network security. These solutions focus on managing and securing the network infrastructure as opposed to adding hardware or indiscriminately blocking traffic.
- A. Correct.
Correct: VLANs (Virtual Local Area Networks) allow the segmentation of network traffic, reducing broadcast traffic and improving performance and security.
- B. Incorrect.
Incorrect: Blocking all incoming traffic with a firewall would disrupt legitimate communication and is not a practical solution for this issue.
- C. Correct.
Correct: SD-WAN can optimize traffic routing through more intelligent path selection, thereby improving performance.
- D. Incorrect.
Incorrect: Adding physical servers may reduce load on specific servers but does not address the fundamental issue of network segmentation or routing.
- E. Correct.
Correct: Configuring ACLs helps to restrict unauthorized access, enhancing security for a segmented network.
