Cisco Designing Cisco Enterprise Networks Sample Questions (Q99-Q104):

NEW QUESTION # 99

Refer to the exhibit. An architect is developing a solution to consolidate networks while retaining device redundancy. The routing protocol for the WAN routers must be open standard, ensure high availability, and provide the fastest convergence time. Which solution must the design include?

Answer: B

Explanation:
Both WAN routers should run OSPFv2. The requirement explicitly says that the routing protocol must be open standard, provide high availability, and offer fast convergence. OSPF is an open-standard link-state routing protocol and is broadly supported across vendors. It builds a link-state database, calculates best paths with SPF, supports equal-cost multipath, and can be tuned with BFD, SPF throttling, LSA throttling, and hierarchical areas for resilient enterprise WAN designs. EIGRP is fast and operationally efficient in Cisco- only environments, but it is not the best answer when the requirement emphasizes an open-standard routing protocol. Running OSPFv2 on one router and OSPFv3 on another is invalid for a single IPv4 routing design because they would not form the intended common routing domain. Mixing IS-IS and OSPFv3 also fails the requirement for a unified design between the redundant routers. Therefore, both routers should run OSPFv2.
Reference topics: OSPFv2, open-standard routing, WAN routing high availability, link-state convergence, ECMP and BFD integration.


NEW QUESTION # 100
Refer to the exhibit. Which process does the Ethernet LMI protocol follow that is defined by the MEF 16 Technical Specification?

Answer: D


NEW QUESTION # 101
An engineer uses Postman and YANG to configure a router with:

Which get-config replay verifies that the model set was designed correctly?



Answer: C


NEW QUESTION # 102
Refer to the exhibit.

An architect is designing a network for a customer supporting a Wake-on-LAN application. Which solution must the architect choose?

Answer: C

Explanation:
"IP directed broadcast" must be supported on the last router to the destination subnet. Since the sleeping PC's dont have IP adresses, the machines must be calles awake by broadcast that behaves like an unicast untill they reach the destination network. There the directed broadcast is handled like a proper broadcast to wake all WOL machines.

NEW QUESTION # 103
Refer to the exhibit.

EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

Answer: B


NEW QUESTION # 104
