Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 266

A network engineer is configuring two dedicated Internet connections within the Internet module. One connection is the primary connection to all wired business communications, while the other is the primary connection for all customer wireless traffic. If one of the links goes down, the affected traffic needs to be redirected to the redundant link.
Which current technology should be deployed to monitor the scenario?

Answer options

• A. PBR
• B. IP QoS
• C. MMC
• D. IP SLA
• E. IP SAA

Correct answer: D

Explanation

The correct answer is IP SLA because it is designed to monitor the performance of network connections and can detect failures, allowing for traffic to be redirected. The other options, such as PBR (Policy-Based Routing) and IP QoS (Quality of Service), do not inherently provide monitoring capabilities for link failures, while MMC and IP SAA are not relevant to this specific scenario.
