Cisco 300-420: Skills outline
Cisco 300-420 is a certification test that evaluates the individuals’ understanding of a wide range of knowledge areas. The skills measured in this exam are combined in various objectives, which are enumerated below:
- WAN for Enterprise Networks (20%)
This area evaluates one’s skills and knowledge of building frameworks, which make network communication resources and services available to end-users and systems. The questions under this objective also require that the students be able to compare WAN connectivity options, design site-to-site VPN, and design Cisco SD-WAN architecture. It is also important to know about failover, backup connectivity, multihomed, and single-homed.
- Network Services (20%)
To answer the questions in this topic, the individuals should be able to demonstrate that they have the relevant knowledge and are capable of selecting and employing the most appropriate quality strategies, which will help meet the customer’s requirements. Other skills under this section include describing network management techniques, designing multicast services (MSDP, SSM, PIM bidirectional), and describing multicast routing concepts (RPF, source trees, shared trees, and rendezvous points).
- Automation (10%)
This domain is all about testing the applicants on their knowledge of various data model sets that enable service providers to effectively and actively manage the networks of their end-users. In the framework of this subject, they need to demonstrate their competency in comparing dial-in and dial-out approaches to model-driven telemetry, describing the effect of model-driven telemetry on the network, differentiating between RESTCONF and NETCONF, choosing the right YANG data model set according to the requirements and choosing the right QoS strategies to meet the requirements of a customer.
- Advanced Addressing and Routing Solutions (25%)
Within this topic, the applicants are required to demonstrate their knowledge of advanced addressing & routing solutions. This means that they need to be well conversant with creating stable, scalable, and secure routing designs for different routing protocols, including EIGRP, IS-IS, OSPF, and BGP. They should also be conversant with IPv6 migration strategies that include Boundaries, Native, and Overlay.
- Advanced Enterprise Campus Networks (25%)
In the framework of this knowledge area, the learners are expected to show their competency in designing campus networks for high availability, designing campus Layer 2 and multicampus Layer 3 infrastructures. The potential candidates should also know about SD-Access architecture and SD-Access fabric design considerations for both wired and wireless access.

NEW QUESTION 43
Which statements about RSPAN are true? (Choose two.)
- A. only one RSPAN VLAN can be configured per device.
- B. RSPAN VLANS can carry RSPAN traffic only.
- C. RSPAN VLANs are exempt from VTP pruning.
- D. RSPAN uses are GRE tunnel to transmit captured traffic.
- E. It supports MAC address learning.
- F. MAC address learning is not supported
Answer: B,F
Explanation:
The RSPAN VLAN carries SPAN traffic between RSPAN source and destination sessions. It has these special characteristics:
All traffic in the RSPAN VLAN is always flooded.
No MAC address learning occurs on the RSPAN VLAN.
RSPAN VLAN traffic only flows on trunk ports.
RSPAN VLANs must be configured in VLAN configuration mode by using the remote-span VLAN configuration mode command.
STP can run on RSPAN VLAN trunks but not on SPAN destination ports.
An RSPAN VLAN cannot be a private-VLAN primary or secondary VLAN.
For VLANs 1 to 1005 that are visible to VLAN Trunking Protocol (VTP), the VLAN ID and its associated RSPAN characteristic are propagated by VTP. If you assign an RSPAN VLAN ID in the extended VLAN range (1006 to 4094), you must manually configure all intermediate switches.
It is normal to have multiple RSPAN VLANs in a network at the same time with each RSPAN VLAN defining a network-wide RSPAN session. That is, multiple RSPAN source sessions anywhere in the network can contribute packets to the RSPAN session. It is also possible to have multiple RSPAN destination sessions throughout the network, monitoring the same RSPAN VLAN and presenting traffic to the user. The RSPAN VLAN ID separates the sessions.
