Q33. A company is deciding between an HVR and SVR solution in order to finalize a virtualization project proposal. Which is an advantage of a HVR solution versus a SVR solution? 

A. A HVR solution implements dedicated data plane resources. 

B. A HVR solution implements shared control plane resources. 

C. A HVR solution introduces significant contention of resources. 

D. A HVR solution implements dedicated chassis resources. 

Answer: A 

Explanation: 

Comparison of Virtualized Routing Architectures 

Category Hardware-Isolated Virtual Router Software-Isolated Virtual Router 

Control plane resources (CPU, memory) 

Dedicated 

Shared 

Data plane resources (forwarding engine, queues) 

Dedicated 

Shared 

Chassis resources (power supplies, blowers, fabric) 

Shared 

Shared 

Management, configuration 

Dedicated 

Typically shared, but varies depending on degree of virtualization 

Connections between virtualized routing entities 

Typically external 

Typically internal, but possibly external 

Per-chassis scalability (routing adjacencies, prefixes) 

Increased with additional logical routers 

Unaffected by additional virtual routers
