Question
Which of the following functions is used to prioritize network traffic based on the type of traffic?
Options
- AQoS
- BVPN
- CCDN
- DTTL
Explanation
Quality of Service (QoS) is the function used to prioritize different types of network traffic, ensuring critical data receives preferential treatment.
Common mistakes.
- B. A VPN (Virtual Private Network) creates a secure, encrypted tunnel over a public network, primarily for confidentiality and integrity, not for prioritizing traffic based on type.
- C. A CDN (Content Delivery Network) distributes content geographically to improve delivery speed and availability, but it does not inherently prioritize traffic types within a network.
- D. TTL (Time To Live) is a mechanism that limits the lifespan of a packet on a network to prevent it from looping indefinitely, not for prioritizing traffic.
