300-415 Question #318: Real Exam Question with Answer & Explanation

The correct answer is C: Application, SLA, VPN, Prefix. To configure application-aware routing, the network team must define SLA classes to specify path preferences, the VPN to which the policy applies, and the data prefixes to identify the traffic scope.

Policies

Question

Refer to the exhibit. The network team must configure application-aware routing for the Service VPN 50.0.0.0/16. The SLA must prefer MPLS for video traffic, but the remaining traffic must use a public network. What must be defined other than applications before the application-aware policy is created?

Options

AColor, SLA Class, Site, VPN
BData Prefix, Site, VPN, TLOC
CApplication, SLA, VPN, Prefix
DSLA Class, Site, VPN, Prefix

Explanation

To configure application-aware routing, the network team must define SLA classes to specify path preferences, the VPN to which the policy applies, and the data prefixes to identify the traffic scope.

Common mistakes.

A. "Color" and "Site" are attributes of the transport or device, not direct components defined as prerequisites for the application-aware policy itself in this context.
B. "TLOC" is a transport location identifier, which is part of the underlying network but not a configuration element defined before the application-aware policy creation itself.
D. "Site" is a device-level attribute and not a direct component that needs to be defined as part of the application-aware routing policy configuration.
