Which two actions must take place for proper operation when using Advanced Networking on Cisco VCS? (Choose two)

The correct answer is C. Manual routes must be added using xCommand RouteAdd E. Network interfaces must reside in separate subnets. Cisco VCS Advanced Networking uses dual network interfaces to separate traffic, requiring separate subnets and manually configured static routes to direct traffic correctly.

Why each option

Cisco VCS Advanced Networking uses dual network interfaces to separate traffic, requiring separate subnets and manually configured static routes to direct traffic correctly.

AAutomatic routing must be enabled

There is no 'automatic routing' feature on VCS that handles dual-NIC routing; static routes must be added manually.

BNAT refection must be enabled on the firewall

NAT reflection is a firewall feature that addresses hairpin NAT traversal and is not a requirement for VCS Advanced Networking to operate.

CManual routes must be added using xCommand RouteAddCorrect

Because VCS does not automatically populate routing tables for a second NIC, an administrator must use xCommand RouteAdd to manually define static routes so that traffic destined for remote subnets egresses the correct interface.

DNetwork interfaces must reside in the same subnet

Placing both interfaces in the same subnet defeats the purpose of Advanced Networking and would create a routing conflict, not enable proper operation.

ENetwork interfaces must reside in separate subnetsCorrect

Advanced Networking is designed to place LAN1 and LAN2 on logically separate subnets, which is the fundamental requirement that enables VCS to differentiate which traffic should use which interface.
