R1 is configured with IP SLA to check the availability of the server behind R6 but it kept failing.
Which configuration resolves the issue?
- A . R6(config)# ip sla responder
- B . R6(config)# ip sla responder udp-echo ip address 10.10.10.1 port 5000
- C . R6(config)# ip access-list extended DDOS
R6(config ext-nac)# 5 permit icmp host 10.66 66.66 host 10.10.10.1 - D . R6(config)# ip access-list extended DDOS
R6(config ext-nac)# 5 permit icmp host 10.10.10.1 host 10.66.66.66
D
Explanation:
In this IP SLA tracking, we don’t need a IP SLA Responder so the command “ip sla responder” on R6 is not necessary.
We also notice that the ACL is blocking ICMP packets on both interfaces E0/0 & E0/1 of R6 so we need
to allow ICMP from source 10.10.10.1 to destination 10.66.66.66.
An engineer configured the wrong default gateway for the Cisco DNA Center enterprise interface during the install.
Which command must the engineer run to correct the configuration?

- B . sudo maglev install config update
- C . sudo maglev reinstall
- D . sudo update config install
Refer to the exhibit.
# Show IP route on R1
All the serial between R1, R2, and R3 have the Same bandwidth. User on the 192.168.1.0/24 network report slow response times while they access resource on network 192.168.3.0/24. When a traceroute is run on the path. It shows that the packet is getting forwarded via R2 to R3 although the link between R1 and R3 is still up.
What must the network administrator to fix the slowness?
- A . Change the Administrative Distance of EIGRP to 5.
- B . Add a static route on R1 using the next hop of R3.
- C . Remove the static route on R1.
- D . Redistribute theR1 route to EIGRP
Refer to the exhibit.
A network engineer is troubleshooting an AAA authentication issue for R1 from R2 When an engineer tries to open a telnet connection to R1 it opens the connection but shows a %Authorization failed error message on the terminal and closes the connection silently.
Which action resolves the issue?
- A . Resolve tacacs+ server host IP authentication miss configuration on the R1 router
- B . Resolve tacacs+ server reachability from the R1 router.
- C . Configure the tacacs+ server host IP on the R1 router
- D . Configure authorization commands in the tacacs* server for the R1 router.
Refer to the exhibit.
A network administrator redistributed the default static route into OSPF toward all internal routers to reach to Internet.
Which set of commands restores reachability to the Internet by internal routers?
- A . router ospf 1default-information originate
- B . router ospf 1network 0.0.0.0 0.0.0.0 area 0
- C . router ospf 1redistribute connected 0.0.0.0
- D . router ospf 1redistribute static subnets
Which control plane process allows the MPLS forwarding state to recover when a secondary RP takes over from a failed primary RP?
- A . MP-BGP uses control plane services for label prefix bindings in the MPLS forwarding table
- B . LSP uses NSF to recover from disruption *i control plane service
- C . FEC uses a control plane service to distribute information between primary and secondary processors
- D . LDP uses SSO to recover from disruption in control plane service
Refer to the exhibit.
Mutual redistribution is enabled between RIP and EIGRP on R2 and R5.

Refer to the exhibit.
Which two actions should be taken to access the server? (Choose two.)
- A . Modify the access list to add a second line of permit ip any
- B . Modify the access list to deny the route to 192.168.2.2.
- C . Modify distribute list seq 10 to permit the route to 192.168.2.2.
- D . Add a sequence 20 in the route map to permit access list 1.
- E . Add a floating static route to reach to 192.168.2.2 with administrative distance higher than OSPF
An engineer configured a DHCP server for Cisco IP phones to download its configuration from a TFTP server, but the IP phones failed to toad the configuration.
What must be configured to resolve the issue?
- A . BOOTP port 67
- B . DHCP option 66
- C . BOOTP port 68
- D . DHCP option 69
B
Explanation:
DHCP options 3, 66, and 150 are used to configure Cisco IP Phones. Cisco IP Phones download their configuration from a TFTP server. When a Cisco IP Phone starts, ifit does not have both the IP address and TFTP server IP address preconfigured, it sends a request with option 150 or 66 to the DHCP server to obtain this information.
+ DHCP option 150 provides the IP addresses of a list of TFTP servers.
+ DHCP option 66 gives the IP address or the hostname of a single TFTP server.
