A large scale IP SLA deployment is causing memory and CPU shortages on the routers in an enterprise network. Which solution can be implemented to mitigate these issues?
The correct answer is A. a shadow router. A shadow router is a dedicated device whose sole purpose is to generate and process IP SLA probes. By offloading IP SLA operations from production routers to the shadow router, CPU and memory pressure on the main routers is eliminated. A CPE device managed by the provider (B)…

Explanation
A shadow router is a dedicated device whose sole purpose is to generate and process IP SLA probes. By offloading IP SLA operations from production routers to the shadow router, CPU and memory pressure on the main routers is eliminated. A CPE device managed by the provider (B) is a customer-premises device and is unrelated to IP SLA offloading. A standby router (C) provides failover, not IP SLA offloading. An offline disaster recovery router (D) is also irrelevant to real-time SLA probe resource consumption.
