Free Cisco 300-420 Exam Actual Questions

Note: Premium Questions for 300-420 were last updated On May. 04, 2025 (see below)

Question #1

An engineer is designing a PIM Anycast RP solution between two data centers. The design must ensure that RP1 in DC1 and RP2 in DC2 inform each other about specific sources that have joined locally. Which solution must the engineer choose?

Reveal Solution Hide Solution
Correct Answer: B

In Anycast RP, two or more RPs are configured with the same IP address on loopback interfaces. The Anycast RP loopback address should be configured with a 32-bit mask, making it a host address. All the downstream routers should be configured to 'know' that the Anycast RP loopback address is the IP address of their local RP. IP routing automatically will select the topologically closest RP for each source and receiver.

MSDP used for Anycast RP is an intradomain feature that provides redundancy and load-sharing capabilities. Enterprise customers typically use Anycast RP for configuring a Protocol Independent Multicast sparse mode (PIM-SM) network to meet fault tolerance requirements within a single multicast domain.

https://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ip_multicast/White_papers/anycast.html#wp1029118

https://www.cisco.com/c/en/us/support/docs/ip/ip-multicast/115011-anycast-pim.html

' You need to have a loopback on each prospective RP router, which is different than the loopback that is being used as the RP address.'


Question #2

Which AES mode should be used in a Cisco SD-WAN environment that includes multicast applications?

Reveal Solution Hide Solution
Correct Answer: C

Question #3

An architect is designing a network solution for a customer The network is IPv6-only with 1000 hosts. The design must provide external access to up to 10 concurrent IPv6 hosts to allow communication with legacy IPv4 devices on an adjacent network. The customer set aside 10 IPv4 addresses to allow for one-to-one communication between hosts. Which solution must the architect select?

Reveal Solution Hide Solution
Correct Answer: A

Question #4

In a Cisco SD-Access fabric, switch node Is equivalent to an access layer switch In a traditional three-tier campus network design?

Reveal Solution Hide Solution
Correct Answer: A

Question #5

Refer to the exhibit.

Refer to the exhibit. A customer is planning to onboard three new VPN partner connections in the data center. The new subnets must not overlap with the existing data center network, and the subnet size must not be bigger than necessary. The customer dedicated 10.1.8.0/21 for this design. Ho1// must the subnets be divided to meet these requirements?
