CompTIA Security+ (SY0-601) — Question 392

An organization relies on third-party videoconferencing to conduct daily business. Recent security changes now require all remote workers to utilize a VPN to corporate resources. Which of the following would best maintain high-quality videoconferencing while minimizing latency when connected to the VPN?

Answer options

• A. Using geographic diversity to have VPN terminators closer to end users
• B. Utilizing split tunneling so only traffic for corporate resources is encrypted
• C. Purchasing higher bandwidth connections to meet the increased demand
• D. Configuring QoS properly on the VPN accelerators

Correct answer: D

Explanation

Configuring QoS on the VPN accelerators ensures that videoconferencing traffic is prioritized, thereby maintaining high quality and reducing latency. While split tunneling and bandwidth upgrades can help, they don't specifically address the prioritization of videoconferencing traffic as effectively as QoS. Geographic diversity can improve access speed, but it doesn't directly enhance the quality of the videoconferencing experience.
