Refer to the exhibit.
An IP SLA was configured on router R1 that allows the default route to be modified in the event that Fa0/0 loses reachability with the router R3 Fa0/0 interface. The route has changed to flow through router R2.
Which debug command is used to troubleshoot this issue?
- A . debug ip flow
- B . debug ip sla error
- C . debug ip routing
- D . debug ip packet
Which configuration enabled the VRF that is labeled “Inet” on FastEthernet0/0?
- A . R1(config)# ip vrf Inet
R1(config-vrf)#interface FastEthernet0/0
R1(config-if)#ip vrf forwarding Inet - B . R1(config)#router ospf 1 vrf Inet
R1(config-router)#ip vrf forwarding FastEthernet0/0 - C . R1(config)#ip vrf Inet FastEthernet0/0
- D . R1(config)# ip vrf Inet
R1(config-vrf)#ip vrf FastEthernet0/0
Refer to the exhibit.
After redistribution is enabled between the routing protocols; PC2, PC3, and PC4 cannot reach PC1.
Which action can the engineer take to solve the issue so that all the PCs are reachable?
- A . Set the administrative distance 100 under the RIP process on R2.
- B . Filter the prefix 10.1.1.0/24 when redistributed from OSPF to EIGRP.
- C . Filter the prefix 10.1.1.0/24 when redistributed from RIP to EIGRP.
- D . Redistribute the directly connected interfaces on R2.
Which command allows traffic to load-balance in an MPLS Layer 3 VPN configuration?
- A . multi-paths eibgp 2
- B . maximum-paths 2
- C . Maximum-paths ibgp 2
- D . multi-paths 2
Refer to the exhibit.
After applying IPsec, the engineer observed that the DMVPN tunnel went down, and both spoke-to-spoke and hub were not establishing.
Which two actions resolve the issue? (Choose two.)
- A . Configure the crypto isakmp key cisco address 192.1.1.1 on R2 and R3
- B . Configure the crypto isakmp key cisco address 0.0.0.0 on R2 and R3.
- C . Change the mode from mode tunnel to mode transport on R3
- D . Change the mode from mode transport to mode tunnel on R2.
- E . Remove the crypto isakmp key cisco address 10.1.1.1 on R2 and R3
Which statement about route distinguishers in an MPLS network is true?
- A . Route distinguishers allow multiple instances of a routing table to coexist within the edge router.
- B . Route distinguishers are used for label bindings.
- C . Route distinguishers make a unique VPNv4 address across the MPLS network.
- D . Route distinguishers define which prefixes are imported and exported on the edge router.
Which statement about MPLS LDP router ID is true?
- A . If not configured, the operational physical interface is chosen as the router ID even if a loopback is configured.
- B . The loopback with the highest IP address is selected as the router ID.
- C . The MPLS LDP router ID must match the IGP router ID.
- D . The force keyword changes the router ID to the specified address without causing any impact.
Refer to the exhibit.
Which interface configuration must be configured on the spoke A router to enable a dynamic DMVPN tunnel with the spoke B router?
- A . Option A
- B . Option B
- C . Option C
- D . Option D
Which list defines the contents of an MPLS label?
- A . 20-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
- B . 32-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
- C . 20-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
- D . 32-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
Refer to the exhibit.
