Cisco 300-420 exam evaluates the candidate’s knowledge and skills in designing and implementing advanced routing and switching technologies, security, wireless, and network services. 300-420 exam aims to test the candidate’s ability to design a scalable and robust network infrastructure that can meet the demands of modern-day businesses.

NEW QUESTION 89

Refer to the exhibit A customer wants to adopt a dynamic site-to-site VPN solution to secure communication for VoIP, video, and FTP traffic between the remote branches and the headquarters. The customer also wants the branches to communicate directly, thereby reducing traffic at the headquarters location. The solution must consider that the branch routers are limited in available memory. Which VPN solution meets these requirements?

DMVPN Phase 2 Hub and Spoke design

DMVPN Phase 3 Hub and Spoke design

DMVPN Phase 1 Hub and Spoke design

DMVPN Phase 3 Hierarchical design

NEW QUESTION 90
An engineer must use YANG with an XML representation to configure a Cisco IOS XE switch with these specifications:
IP address 10.10.10.10/27 configured on the interface GigabitEthernet2/1/0 connectivity from a directly connected host 10.10.10.1/27 Which YANG data model set must the engineer choose?

NEW QUESTION 91
Refer to the exhibit. An architect must design a solution to connect the two ASs. To optimize bandwidth, the design will implement load sharing between router R6 and router R4. Which solution should the design include?

Use update-source to specify the Loopback interface.

Use next-hop-serf attributes only for routes that are learned from eBGP peers.

Configure the eBGP TTL to support eBGP multihop.

Use maximum-paths to install multiple paths in the routing table.

NEW QUESTION 92
Drag and drop the properties from the left onto the protocols they describe on the right.

NEW QUESTION 93

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?

split-horizon

summarization

down bit

route tags

NEW QUESTION 94
Which design consideration must be made when using IPv6 overlay tunnels?

Overlay tunnels that connect isolated IPv6 networks can be considered a final IPv6 network architecture.

Overlay tunnels should only be considered as a transition technique toward a permanent solution.

Overlay tunnels can be configured only between border devices and require only the IPv6 protocol stack.

Overlay tunneling encapsulates IPv4 packets in IPv6 packets for delivery across an IPv6 infrastructure.

NEW QUESTION 95
Refer to the exhibit. Where must an architect plan for route summarization for the topology?

from the aggregation toward the access and the access toward the aggregation

from the aggregation toward the core and the aggregation toward the access

from the core toward the aggregation and the aggregation toward the core

NEW QUESTION 96
An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a
100Mbps CIR. The ISP aggressively drops all traffic received over which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution engineer choose?

Policing

Traffic shaping

Policer with markdown

Queuing

NEW QUESTION 97
Refer to the exhibit.
C0FD9 F48C9ACDC725EA850EC2476EE1E

An architect must design a solution that uses the direct link between R1 and R2 for traffic from 10.10.10.0/24 toward network 10.10.20.0/24. Which solution should the architect include in the design?

Configure the OSPF cost of the link to a value lower than 30.

Lower the Administrative Distance for OSPF area 0.

Place the link into area 2 and install a new link between R1 and R2 in area 0.

Configure the link to provide multiarea adjacency.

NEW QUESTION 98
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?

PIM-SM

PIM-SSM

any-source multicast

BIDIR-PIM

NEW QUESTION 99
Which statements about RSPAN are true? (Choose two.)

It supports MAC address learning.

RSPAN VLANS can carry RSPAN traffic only.

only one RSPAN VLAN can be configured per device.

RSPAN VLANs are exempt from VTP pruning.

MAC address learning is not supported

RSPAN uses are GRE tunnel to transmit captured traffic.

NEW QUESTION 100
How are wireless endpoints registered in the HTDB in a Cisco SD-Access architecture?

Fabric edge nodes update the HTDB based on CAPPWAP messaging from the AP

Fabric WLCs update the HTDB as new clients connect to the wireless network

Border nodes first register endpoints and then update the HTDB

Fabric APs update the HTDB with the clients’ ElD and RLOC

NEW QUESTION 101
The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to of mark traffic traveling between branch sites?

LLQ with DSCP EF

CBWFQ with DSCP AF3

CBWFQ with DSCP AF2

LLQ with DSCP AF4

NEW QUESTION 102
Which design element should an engineer consider when multicast is included in a Cisco SD-Access architecture?

PIM SSM must run in the underlay.

Multicast clients reside in the underlay, and the multicast source is outside the fabric or in the overlay.

Rendezvous points must be used in a PIM SSM deployment.

Multicast traffic is transported in the overlay and the EID space for wired and wireless clients.

NEW QUESTION 103
Which method does Cisco SD-WAN use to avoid fragmentation issues?

PMTUD is used.

Traffic is marked with the DF bit set.

Jumbo frames are enabled.

Access circuits are configured with 1600 byte MTU settings.

NEW QUESTION 104
Drag and drop the characteristics from the left onto the YANG modules they describe on the right. Not all options are used.

NEW QUESTION 105
An architect is working on a design to connect a company’s main site to several small to medium-sized remote branches. The solution must include redundant WAN links, but the customer has a limited budget and wants the ability to increase the link speed easily in the future. QoS will not on the branch routers so there is no need for consistent end-to-end QoS. Which solution does the architect propose?

dual-homed WAN MPLS with single edge router

dual-homed Internet with a single edge router running a site-to-site VPN topology

dual-homed WAN MPLS and Internet links via dual edge routers
