B. Layer 2
C. Layer 1
D. Layer 3
Correct Answer: B
Question 5:
A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link. Which approach achieves this goal and does not impact router CPU utilization?
A. Utilize BFD and tune the multiplier to 50
B. Lower the BGP hello interval
C. Decrease the BGP keepalive timer
D. Utilize BFD and keep the default BGP timers
Correct Answer: D
Question 6:
Which component is part of the Cisco SD-Access overlay architecture?
A. border node
B. spine node
C. leaf node
D. Cisco DNA Center
Correct Answer: D
Question 7:
Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?
A. DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.
B. A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.
C. DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD-Access fabric with anycast gateway.
D. DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discovery originated.
Correct Answer: D
Question 8:
Refer to the exhibit. The distribution switches serve as the layer 3 boundaries. HSRP preemption is enabled. When the primary switch comes back after a failure, traffic is initially dropped. Which solution must be implemented to improve the design?
A. Increase the hello timers on both HSRP devices
B. Use the preempt delay feature on the primary HSRP device.
C. Use the preempt delay feature on the backup HSRP device
D. Configure a higher mac-refresh interval on both HSRP devices
Correct Answer: B
Question 9:
An organization plans to deploy multicast across two different autonomous systems. Their solution must allow RPs to:
1.
discover active sources outside their domain
2.
use the underlying routing information for connectivity with other RPs
3.
announce sources joining the group Which solution supports these requirements?
A. SSM
B. MSDP
C. PIM-DM
D. PIM-SM
Correct Answer: B
Question 10:
Refer to the exhibit.
A network engineer is designing a network for AS100. The design should ensure that all traffic enters AS100 via link 1 unless there is a network failure. In the event of a failure, link 2 should function as the path for incoming traffic. Which solution should the design include?
A. Modify the next-hop attribute on R3.
B. Use AS-Path prepending on R3.
C. Modify the next-hop attribute on R4.
D. Use AS-Path prepending on R4.
Correct Answer: D
Question 11:
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 be on the branch routers so there is no need for consistent end-to-end QoS. Which solution does the architect propose?
A. dual-homed WAN MPLS with single-edge router
B. dual-homed Internet with a single edge router running a site-to-site VPN topology
C. dual-homed WAN MPLS and Internet links via dual-edge routers
D. dual-homed Internet with dual edge routers running a hub-and-spoke VPN topology
Correct Answer: B
Question 12:
Which two statements about VRRP object tracking are true? (Choose two)
A. The priority of a VRRP device can change in accordance with the up or down status of a VRRP object
B. The VRRP interface priority must be manually configured by the administrator
C. A VRRP group can track only one object at a time
D. VRRP can track the status of interfaces and routes
E. VRRP supports only internal tracking
Correct Answer: AD

B. greater scalability
C. support for anycast gateway
D. lower traffic overhead
E. dynamic spoke-to-spoke tunnels
Correct Answer: BE
Question 15:
An engineer is upgrading a company\’s main site to include a connection to a second ISP. The company will receive full Internet routing tables from both ISPs via BGP. The engineer must ensure that the company does not become a transit autonomous system. Which solution should be included in this design?
