Cisco CCNP Security Core (SCOR) 350-701Content SecurityEasy
A security engineer is tasked with optimizing the performance of a Cisco Secure Web Appliance (WSA) while maintaining robust security. The goal is to reduce latency for frequently accessed legitimate websites by storing copies of web content locally. Which WSA feature is primarily responsible for this performance enhancement?
- AWeb Caching
- BPolicy-Based Routing (PBR)
- CActive Directory Integration
- DProxy Auto-Configuration (PAC) file
Show answer & explanationAnswer & explanation
Correct answer: A. Web Caching
Web Caching on the Cisco WSA stores copies of frequently accessed web content locally. When a user requests content that is already cached, the WSA serves it directly, reducing latency and bandwidth usage by avoiding fetching it from the internet again.
Why the other options are wrong
- B. PBR is a routing mechanism that directs traffic based on policy, not a feature for caching web content to improve performance.
- C. Active Directory Integration is for user authentication and policy enforcement, not for performance optimization through content storage.
- D. A PAC file is used to direct client browser traffic to the WSA, but it doesn't directly enhance performance by storing web content.
WSA Web Caching
A feature of the Cisco Secure Web Appliance (WSA) that stores copies of frequently accessed web content locally to reduce latency and bandwidth consumption.
- Improves user experience by speeding up web access.
- Reduces internet bandwidth usage.
- Can be configured with various caching policies.
Memory trick: Cache the web, speed up the net.
