Question 96

Which solution allows overlay VNs to communicate with each other in an SD-WAN Architecture?

A.External fusion routers can be used to map VNs to VRFs and selectively route traffic between VRFs.

B.GRE tunneling can be configured between fabric edges to connect one VN to another.

C.SGTs can be used to permit traffic from one VN to another.

D.Route leaking can be used on the fabric border nodes to inject routes from one VN to another.

Question 97

Refer to the exhibit. Where must an architect plan for route summarization for the topology?

A.from the aggregation toward the access and the access toward the aggregation

B.from the aggregation toward the core and the aggregation toward the access

C.from the core toward the aggregation and the aggregation toward the core

Question 98

A customer's current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:
* reduce the impact of topology changes
* reduce the time spent on network administration
* reduce manual configuration errors
Which two solutions should the architect include in the new design? (Choose two.)

A.Implement Rapid PVST+ instead of STP.

B.Implement MST instead of STP.

C.Use VTP to propagate VLAN information and to prune unused VLANs.

D.Configure broadcast and multicast storm control on all switches.

E.Configure dynamic trunking protocol to propagate VLAN information.

Question 99

Which design consideration must be made when dual WAN Edge routers are deployed at a branch site?

A.Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.

B.HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.

C.Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.

D.Configure BFD between WAN Edge routers to detect sub-second link failures.

Question 100

Which two statements about VRRP advertisements are true? (Choose two.)

A.They include VRRP timer information.

B.They are sent from the master router and standby routers.

C.They are sent every three seconds by default.

D.They include priority information.

E.They are sent only from the master router.
