Policies

Question

Refer to the exhibit. An enterprise requires spoke sites 102 and 103 to use the MPLS circuit to reach the 172.16.101.0/24 subnet (Service VPN 100) advertised by site 101 (Hub Site). Which policy configuration meets this requirement?

Options

Aapply-policy site-list Spokes control-policy Route-Policy site-list Hub control-policy Route-Policy in
Bapply-policy site-list Spokes control-policy Route-Policy out
Capply-policy site-list Hub control-policy Route-Policy in
Dapply-policy site-list Hub control-policy Route-Policy out

Explanation

To ensure spoke sites utilize the MPLS circuit to reach a specific subnet at the hub site, an inbound control policy must be applied to the spokes.

Common mistakes.

B. Applying an outbound policy on spokes would affect routes advertised by the spokes, not how they reach a subnet advertised by the hub.
C. Applying an inbound policy on the hub would affect routes received by the hub, not how spokes reach the hub.
D. Applying an outbound policy on the hub would affect routes advertised by the hub, but the requirement is for spokes to use MPLS, which means spokes need to process the received routes accordingly.
