[Q11-Q33] 300-420 Certification – The Ultimate Guide [Updated 2022]

NO.11 Refer to the exhibit. An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routes belonging to the network, including EIGRP, except the ones originated in the RIP domain. Which action should the engineer take?

NO.12

Refer to the exhibit. An architect must design a solution to connect the network behind R3 with the EIGRP network. Which mechanism should be included to avoid routing loops?

NO.13 In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?

NO.14 Which type of rendezvous point deployment is standards-based and support dynamic RP discovery?

NO.15 An engineer must design an addressing plan for a small business using a single /24 network. Each department must have its own subnet. Drag and drop the subnets from the left onto the departments requirements that they fulfill on the right. Not all options are used.

NO.16 An engineer must propose a solution for a campus network that includes the capability to create multiple Layer
3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding.
The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?

NO.17 Refer to the exhibit.

An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routes belonging to the network, including EIGRP, except the ones originated in the RIP domain. Which action should the engineer take?

NO.18 A customer’s current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:

NO.19 An engineer is working for a large cable TV provider that requires multiple sources streaming video on different channels using multicast with no rendezvous point. Which multicast protocol meets these requirements?

NO.20 Drag and drop the characteristics from the left onto the configuration protocols they describe on the right.

NO.21 A customer requests a VPN solution to connect multiple sites with the company headquarters. All the sites use the same IP subnet. The engineer plans to use VPLS. Which solutions must the engineer include in the design?

NO.22 Which control-plane technology allows the same subnet to exist across multiple network locations?

NO.23 Drag and drop the properties from the left onto the protocols they describe on the right.

NO.24 A customer’s environment includes hosts that support IPv6-only. Several of these hosts must communicate with a public web server that has only IPv4 domain name resolution. Which solution should the customer use in this environment?

NO.25 Which method will filter routes between EIGRP neighbors within the same autonomous system?

NO.26 See the solution below
Explanation/Reference:
There are two ways to configure interVLAN routing in this case:
+ Use RouterC as a “router on a stick” and SwitchC as a pure Layer2 switch. Trunking must be established between RouterC and SwitchC.
+ Only use SwitchC for interVLAN routing without using RouterC, SwitchC should be configured as a Layer 3 switch (which supports ip routing function as a router). No trunking requires.
The question clearly states “No trunking has been configured on RouterC” so RouterC does not contribute to interVLAN routing of hosts H1 & H2 -> SwitchC must be configured as a Layer 3 switch with SVIs for interVLAN routing.
We should check the default gateways on H1 & H2. Click on H1 and H2 and type the “ipconfig” command to get their default gateways.

NO.27 What is the purpose of an edge node in an SD-Access network fabric?

NO.28 A company is running BGP on a single router, which has two connections to the same ISP. Which BGP feature ensures traffic is load balanced across the two links to the ISP?

NO.29 A customer’s current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:
* reduce the impact of topology changes
* reduce the time spent on network administration
* reduce manual configuration errors
Which two solutions should the architect include in the new design? (Choose two.)

NO.30

Refer to the exhibit. An engineer is designing an OSPF network for a client. Requirements dictate that the routers in Area 1 should receive all routes belonging to the network, including EIGRP, except the ones originated in the RIP domain. Which action should the engineer take?

NO.31 A network administrator is troubleshooting a DMVPN setup between the hub and the spoke. Which action should the administrator take before troubleshooting the IPsec configuration?

NO.32 Which feature must be incorporated into the campus LAN design to enable Wake on LAN?

NO.33 How do endpoints inside an SD-Access network reach resources outside the fabric?
