Cisco 300-420 Exam covers a wide range of topics related to designing enterprise networks, including network design methodologies, network security, routing protocols, switching technologies, wireless LANs, and WAN technologies. Candidates are expected to have a deep understanding of network protocols, including TCP/IP, OSPF, BGP, and EIGRP. They must also have a good grasp of network security concepts, such as firewalls, VPNs, and secure network design.

Cisco Designing Cisco Enterprise Networks Sample Questions (Q300-Q305):

NEW QUESTION # 300

Refer to the exhibit. An architect must design a solution to connect bank site A with bank site B and support:
* network operation center monitoring end-to-end L3VPN and L2VPN traffic
* company adding thousands of routes in the next two years
Which two BGP solutions must the design include? (Choose two.)

Answer: A,C


NEW QUESTION # 301
Refer to the exhibit.

An architect must design an IGP solution for an enterprise customer. The design must support:
Physical link flaps should have minimal impact.
Access routers should converge quickly after a link failure.
Which two ISIS solutions should the architect include in the design? (Choose two.)

Answer: B,C

Explanation:
The correct IS-IS design combines tuned SPF/PRC behavior with a proper Level 1 and Level 2 hierarchy.
Reducing SPF and PRC intervals, within platform and stability limits, helps routers react more quickly to topology changes after a link failure. However, fast timers alone are not enough; the hierarchy must contain instability so physical link flaps in the access layer have limited impact on the rest of the network. Access routers should form Level 1 adjacencies inside their local area, while aggregation routers should operate as Level 1/Level 2 routers to connect the access area to the Level 2 backbone. This design gives access routers a simple local view and uses aggregation as the interarea boundary. Running all access and aggregation routers as L1/L2 across the network increases the size of the backbone and exposes more routers to wider flooding, which is the opposite of the requirement. Redistributing Internet routes into Level 1 is also poor design because it bloats the access area. Therefore, the right choices are C and E. Reference topics: IS-IS hierarchy, L1/L2 design, SPF and PRC tuning, access-layer convergence, fault containment.


NEW QUESTION # 302
A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup. Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?

Answer: B


NEW QUESTION # 303
Refer to the exhibit. Which two solutions maximize the use of the links between the core and distribution layers? (Choose two.)

Answer: A,D


NEW QUESTION # 304

Refer to the exhibit. AS65533 and AS65530 are announcing a partial Internet routing table as well as their IP subnets. An architect must create a design that ensures AS64512 become a transit AS. Which filtering solution must the architect choose?

Answer: D
