An engineer is investigating an OSPF issue reported by the Cisco DNA Assurance Center.
Which action resolves the issue?
- A . One of the neighbor links is down Bring the interface up by running shut and no shut
- B . One of the interfaces is using the wrong MTU Match interface MTU on both links
- C . An ACL entry blocking multicast on the interfaces Allow multicast through the interface ACL
- D . One of the interfaces is using the wrong authentication Match interface authentication on both links
Refer to the exhibit.
Routers R1, R2, R3, and R4 use EIGRP However, traffic always prefers R1 to R5 backup links in nonfailure scenarios.
Which configuration resolves the issue?
A)
B)
C)
D)
- A . Option A
- B . Option B
- C . Option C
- D . Option D
Refer to the exhibit.
A network engineer must establish communication between three different customer sites with these requirements:
✑ Site-A: must be restricted to access to any users at Site-B or Site-C.
✑ Site-B and Site-C must be able to communicate between sites and share routes using OSPF.
Which configuration meets the requirements?
- A . Option A
- B . Option B
- C . Option C
- D . Option D
What is considered the primary advantage of running BFD?
- A . reduction in time needed to detect Layer 2 switched neighbor failures
- B . reduction in time needed to detect Layer 3 routing neighbor failures
- C . reduction in CPU needed to detect Layer 2 switch neighbor failures
- D . reduction in CPU needed to detect Layer 3 routing neighbor failures
Refer to the exhibit.
An engineer has successfully set up a floating static route from the BRANCH router to the HQ network using HQ_R1 as the primary default gateway When the g0/0 goes down on HQ_R1, the branch network cannot reach the HQ network 192.168.20.0/24.
Which set of configurations resolves the issue?
- A . HQ_R3(config)# ip sla responder
HQ_R3(config)# ip sla responder icmp-echo 172.16.35.1 - B . BRANCH(config)# ip sla 1
BRANCH(config-ip-sla)# icmp-echo 192.168.100.2 - C . HQ R3(config)# Ip sla responder
HQ R3(config)# Ip sla responder Icmp-echo 172.16.35.5 - D . BRANCH(config)# Ip sla 1
BRANCH(config-ip-sta)# Icmp-echo 192.168.100.1
How does MPLS Layer 3 VPN function?
- A . When a VPN route is learned from a CE device and injected into IGP, a VPN route distinguisher attribute is associated with it.
- B . When a destination PE device receives a labeled packet, it pops the label and uses it to forward the packet to the correct CE device.
- C . When an EIGRP internal route is redistributed into BGP by one PE and then back into EIGRP by another PE, the originating router ID for the route is changed to the router ID of the first PE
- D . When a PE device forwards a packet received from a CE device across the provider network, it labels the packet with the label learned from the source PE device.
The network administrator configured R1 to authenticate Telnet connections based on Cisco ISE using TACACS+. ISE has been configured with an IP address of 192.168.1.5 and with a network device pointing toward R1(192.168.1.1) with a shared secret password of Cisco123.
The administrator cannot authenticate to R1 based on ISE.
Which configuration fixes the issue?
- A . ip tacacs-server host 192.168.1.5 key Cisco123
- B . line vty 0 4login authentication TAC-SERV
- C . line vty 0 4login authentication telnet
- D . tacacs-server host 192.168.1.5 key Cisco123
C
Explanation:
The last command “aaa authentication login telnet group TAC-SERV” created the method list name telnet so we need to assign it to line vty.

Refer to the exhibit.
Which action restores the routes from neighbors while still filtering 1.1.1.0/24?
- A . Add a second line in the access list to permit any.
- B . Modify the route map to permit the access list instead of deny it
- C . Modify the access list to deny instead of permit it.
- D . Add a second sequence in the route map permit 20
Refer to the exhibit.
A network engineer is troubleshooting a failed link between R2 and R3 No traffic loss is reported from router R5 to HQ.
Which command fixes the separated backbone?

- B . R2(config_router)#area 21 virtual-link 192.168.125.5
- C . R3(config-router)#area 21 virtual-link 192.168.125.5
- D . R3(config-router)#no area 21 stub
