300-420 Practice Tests: Which Topics Shoud You Practice with Updated Questions

You can download the most updated 300-420 practice tests from DumpsBase to prepare for your Designing Cisco Enterprise Networks (ENSLD) exam. We updated the materials to V15.02 with 379 questions and answers, which can help you check your understanding, work through design scenarios, and identify topics that need more attention.

Which Topics Should You Practice with the Updated Questions?

300-420 practice tests are updated to align with the latest exam objectives. Currently, Cisco 300-420 ENSLD exam topics organize preparation into five domains. As you complete 300-420 practice tests, track your results by domain so you can spend more time where your understanding is weakest.

• Advanced addressing and routing solutions: IPv4 and IPv6 plans, routing protocol design, BGP, and IPv6 migration.
• Advanced enterprise campus networks: High availability, Layer 2 and Layer 3 design, and software-defined access.
• WAN for enterprise networks: Connectivity options, VPN design, resilience, and SD-WAN considerations.
• Network services: Quality of service, network management, and multicast.
• Automation: Network models, management protocols, telemetry, and cloud connectivity concepts.

The updated 300-420 practice test questions give you a way to apply what you have studied and explain your reasoning. They can also reveal whether you understand why one design fits a scenario better than another.

What Is the Best Way to Use 300-420 Practice Tests?

Use 300-420 practice tests to find knowledge gaps and strengthen design reasoning. Review explanations, return to the relevant exam objectives, and try similar scenarios again after further study. The goal is to make sound enterprise network design decisions, whether you encounter them in a practice question or in your work.

Question 1

An architect must design a plan to manage the enterprise network devices.
The design must accommodate the following requirements:

• Not all network devices have a dedicated management interface.
• All IP-enabled interfaces on all devices must be reachable.
• Encryption must be used with all devices that support it.
  Which solution must the architect choose?
  A. KVM server
  B. In-band management
  C. Out-of-band management
  D. Terminal server
  Answer: B
  Explanation: In-band management uses the devices’ regular IP-enabled interfaces, so it can reach devices that do not have a dedicated management port. Secure protocols such as SSH, HTTPS, and SNMPv3 can provide encryption where supported. A KVM server and a terminal server focus on console-style access, while an out-of-band design normally depends on separate management connectivity.

Question 2

Which type of rendezvous point deployment is standards-based and supports dynamic RP discovery?
A. Bootstrap router
B. Anycast-RP
C. Auto-RP
D. Static RP
Answer: A
Explanation: Bootstrap Router (BSR) is the standards-based PIM-SM method for dynamically distributing rendezvous point information. Auto-RP is Cisco proprietary, a static RP is manually configured, and Anycast-RP improves RP redundancy but does not by itself provide the standards-based dynamic discovery requested here.

Question 3

A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub-and-spoke, and the branches use DMVPN back to the hub using two 100 Mbps internet connections. Both links must be used due to spikes in traffic, and routing must take traffic utilization of the links into account. The branch routers also have limited memory and CPU resources.
Which routing protocol and design solution must the company choose?
A. iBGP with the hub routers set up as route reflectors and branches set up as clients
B. OSPF deployed in area 0 with branch routers connecting from area 1
C. IS-IS with the hub and spoke routers configured in two different areas
D. EIGRP with branch routers as stub routers using ECMP
Answer: D
Explanation: EIGRP stub mode limits route advertisements and query propagation, which reduces control-plane work on resource-constrained branch routers. Equal-cost multipath (ECMP) allows both equal-cost DMVPN links to carry traffic. An iBGP route-reflector design reduces iBGP sessions but does not provide this spoke optimization, while the proposed OSPF and IS-IS designs do not combine EIGRP stub behavior with ECMP as requested.

Question 4

In the SD-WAN underlay network, which WAN Edge VPN ID is defined as the transport VPN and is used to carry control traffic?
A. VPN 0
B. VPN 512
C. VPN 128
D. VPN 256
Answer: A
Explanation: VPN 0 is the Cisco SD-WAN transport VPN. It contains transport-facing interfaces and carries the control traffic used to form the overlay. VPN 512 is reserved for out-of-band management, while VPN 128 and VPN 256 are not the defined transport VPN.

Question 5

A network engineer is redesigning a company’s QoS solution. The company currently uses IP Precedence, but the engineer plans to move to DiffServ. It is important that the new solution provide backward compatibility with the current solution.
Which technology should the design include?
A. Expedited forwarding
B. Assured forwarding
C. Class selector code points
D. Default per-hop behavior
Answer: C
Explanation: Class Selector DSCP values use the xxx000 pattern, preserving the three IP Precedence bits so older IP Precedence markings can map into DiffServ. Expedited Forwarding, Assured Forwarding, and Default PHB define forwarding treatments, but they are not the backward-compatibility mechanism.
