The Cisco 300-420 exam is one of the requirements for the CCNP Enterprise certificate. Since candidates can choose their certification path according to their area of interest, those aiming to design Cisco enterprise networks should choose to take 300-420 test for sure. It validates one's ability to successfully handle different networks, perform advanced routing and addressing, work with WAN, ensure security, and many more.
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.

NEW QUESTION # 66
An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements:
* Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times.
* A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle.
* Download traffic must never experience a delay.
Which solution must the architect choose?
- A. rate-limiting and shaping
- B. shaping and policing
- C. bandwidth percentage and policing
- D. bandwidth percentage and rate-limiting
Answer: C
Explanation:
Explanation
Selected answer: B
"Download traffic must never experience a delay."
This means we shouldn't be using Shaping at any point (since that puts packets into a buffer and sends them out later on when congestion has been reduced) Also: "Rate-limiting" is a bigger term and under it we have 2 things: "Policing" and "Shaping"

NEW QUESTION # 69
Which two routing protocols allow for unequal cost load balancing? (Choose two.)
- A. BGP
- B. RIPng
- C. OSPF
- D. IS-IS
- E. EIGRP
Answer: C,E
Explanation:
Unequal cost load balancing is a feature that allows traffic to be distributed across unequal-cost paths to the same destination, which can increase network utilization and improve overall performance.
EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path First) are two routing protocols that support unequal cost load balancing.
In EIGRP, unequal cost load balancing can be achieved by adjusting the "variance" parameter, which is a multiplier that determines the maximum metric of a feasible successor. The feasible successor is a backup route that meets the feasibility condition, which means its reported distance (the sum of the metric from the successor router and the advertised distance to the destination) is less than the current best path's metric. By default, EIGRP only considers successors with the same metric as the best path, but by increasing the variance, EIGRP can include feasible successors with higher metrics.
In OSPF, unequal cost load balancing can be achieved by enabling the "variance" command, which allows OSPF to use paths with metrics that are up to a certain multiple of the best path's metric. For example, if the variance is set to 2, OSPF can use paths with a metric that is up to twice the metric of the best path.
IS-IS (Intermediate System to Intermediate System) and BGP (Border Gateway Protocol) do not support unequal cost load balancing.
RIPng (Routing Information Protocol next generation) is a distance-vector routing protocol that does not support unequal cost load balancing.
NEW QUESTION # 70
An engineer must design a multicast network for a financial application. Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not use source trees. Which multicast protocol satisfies these requirements?
- A. BIDIR-PIM
- B. PIM-SM
- C. MSDP
- D. PIM-SSM
Answer: A
Explanation:
Explanation
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipmulti_pim/configuration/xe-16/imc-pim-xe-16-book/imc-te Bidir-PIM is designed to be used for many-to-many applications within individual PIM domains. Multicast groups in bidirectional PIM mode can scale to an arbitrary number of sources without incurring overhead due to the number of sources.

NEW QUESTION # 74
An engineer must peer with an ISP for internet connectivity using BGP, initially, the engineer wants to receive only specific prefixes from the ISP and a default route. However, the solution must provide the flexibility to add prefixes in the future at short notice. The ISP has a two-week change process in place. Which route filtering solution must the engineer employ?
- A. Configure outbound route filtering on the enterprise and ISP so that the enterprise tell the ISP which prefixes are required
- B. Request only the required prefixes and default route be advertised from the ISO with whitelisted networks
- C. Request a full internet routing table and a default route from the ISP and configure inbound route filtering with a prefix list that permits the default route and required prefixes
- D. Request a limited internet routing table and a default route from the ISP and configure the BGP max-limit to 1 with an access list that permits only the specific internet prefixes and blocked networks
Answer: C
Explanation:
anychange on the prefix list, engineer only need to update the preifx list and restart the BGP peer to the ISP. soft-reconfiguration inbound could be used to reduce down time of reset BGP peer, but it require lots of memory and in this case, connection to ISP and tons of route learnt will not be apporitated.
