The Cisco 300-420 ENSLD exam in 2025 has evolved beyond the traditional “design-only” format. Cisco now emphasizes real enterprise architecture, zero-trust models, automation-ready topologies, and hybrid cloud networks. Because the exam content continues to shift toward real-world scenarios, outdated study materials can directly reduce your passing chances.
If you are preparing for the 300-420 exam, you must rely on materials aligned with the latest 2025 updates. Many old guides do not match the current blueprint structure, and relying on them will slow down your progress.

Question 1:
DRAG DROP
Drag and drop the model driven telemetry characteristics from the left onto the mode they belong to on the right.
Select and Place:

Correct Answer:

Question 2:
Refer to the exhibit An engineer working for a telecommunication company with an employee ID 4449:30 959 Is calculating STP scalability for switches to ensure that the numbers are below the maximum supported value for STP logical ports

How many logical interfaces are active for switch A?
A. 4
B. 307
C. 202
D. 100
Correct Answer: C
Question 3:
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. 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
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. Configure outbound route filtering on the enterprise and ISP so that the enterprise tell the ISP which prefixes are required
Correct 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.
Question 4:
Which are two advantages of a “one switch at a time” approach to integrating SD-Access into an existing brown field environment? (Choose two.)
A. appropriate for campus and remote site environments
B. allows simplified roll back
C. involves the least risk of all approaches
D. opens up many new design and deployment opportunities
E. ideal for protecting recent investments while upgrading legacy hardware
F. allows simplified testing prior to cutover
Correct Answer: AE
Question 5:
When designing interdomain multicast, which two protocols are deployed to achieve communication between multicast sources and receivers? (Choose two.)
A. IGMPv2
B. BIDIR-PIM
C. MP-BGP
D. MSDP
E. MLD
Correct Answer: CD
Question 6:

Refer to the exhibit. An engineer proposed this solution for a company that requires a loop-free, Layer 2 network design. The network will run 802.1w, and all links will be 1 Gbps. If all interfaces are up as point-to-point adjacencies, what are the expected port end states based on the design?
A. Eth1/2 on SW3 and SW4 will be in an Altn BLK state
B. Eth1/3 on SW2 and SW3 will be in an Altn BLK state

B. PIM-SM
C. MSDP
D. BIDIR-PIM
Correct Answer: D
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.

D. dedicated management VRF connection per device
Correct Answer: D
Question 15:
An engineer is creating a design to enable IPv6 to run on an existing IPv4 IS-IS network. The IPv4 and IPv6 topologies will match exactly, and the engineer plans to use the same IS-IS router levels for each protocol per interface. Which IS-IS design is required?
A. multi topology without enabling transition feature
B. multi topology with transition feature enabled
C. single topology without enabling transition feature
D. single topology with transition feature enabled
Correct Answer: C
Explanation:
C. single topology without enabling transition feature
In a single topology design, both IPv4 and IPv6 addresses can be carried within the same IS-IS domain without creating separate topologies. IS-IS,
being a Layer 2 protocol, can natively support both IPv4 and IPv6. By utilizing a single topology design without any transition feature, the engineer
can enable IPv6 on the existing IPv4 IS-IS network with the same router levels for each protocol per interface, while still maintaining a single,
integrated topology.
