Certification Path

To earn the CCNP Enterprise certification, the applicant first needs to take one core exam that is 350-401. It mainly focuses on one's knowledge related to network assurance, automation, security, infrastructure, architecture, and virtualization.

Once aced that test, the candidate can choose the concentration exam from the set of six options, and Cisco 300-420 is one of them. Moreover, by passing this exam, you are qualified for the Cisco Certified Specialist – Enterprise Design certification. The rest of the offered tests focus on advanced routing and services, designing and implementing wireless networks, SD-WAN, and automation solutions.

Cisco 300-420 exam covers a wide range of topics, including network design methodologies, routing and switching protocols, network security, wireless networking, and network virtualization. Candidates must have a deep understanding of Cisco products and technologies, as well as the ability to design and implement complex network solutions.

 

NEW QUESTION # 137
An engineer is working for a large cable TV provider that requires multiple sources streaming video on different channels using multicast with no rendezvous point. Which multicast protocol meets these requirements?

• A. any-source multicast
• B. BIDIR-PIM
• C. PIM-SM
• D. PIM-SSM

Answer: D

Explanation:
Explanation
PIM-SSM is suitable for when well-known sources exist within the local PIM domain and for broadcast applications. Also, PIM-SSM eliminates the RPs and shared trees

NEW QUESTION # 138
Which design consideration should be observed when EIGRP is configured on Data Center switches?

• A. Prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces.
• B. Lower EIGRP hello and hold timers to their minimum settings to ensure rapid route reconvergence.
• C. Perform manual summarization on all Layer 3 interfaces to minimize the size of the routing table.
• D. Configure multiple EIGRP autonomous systems to segment Data Center services and applications.

Answer: C

NEW QUESTION # 139
An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state. Which solution limits impact on the device and provides the required data?

• A. periodic subscription
• B. IPFIX
• C. on-change subscription
• D. static telemetry

Answer: C

Explanation:
Explanation
There are two types of subscriptions: periodic and on-change. With periodic subscription, data is streamed out to the destination at the configured interval. It continuously sends data for the lifetime of that subscription.
With on-change, data is published only when a change in the data occurs such as when an interface or OSPF neighbor goes down.https://developer.cisco.com/docs/ios-xe/#!streaming-telemetry-quick-start-guide/streaming-telemetry

NEW QUESTION # 145

Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)

• A. a new OSPF area for R3 and R4 connections, with R3 and R4 as ABRs
• B. a new OSPF area for R1 and R2 connections, with R5 and R6 as ABRs
• C. a new OSPF area for R3 and R4 connections, with R5 and R6 as ABRs
• D. a new OSPF area for R1 and R2 connections, with R1 and R2 as ABRs
• E. a new OSPF area for R1, R2, R3, and R4 connections, with R1, R2, R3, and R4 as ABRs

NEW QUESTION # 147
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?

• A. both routers running OSPFv2
• B. both routers running EIGRP
• C. one router running OSPFv2 and other OSPF v3
• D. one router running ISIS and other OSPF v3

Answer: B

Explanation:
EIGRP has a function called "EIGRP Ipv6" (But that can still be called "EIGRP")
