- A. Configure IGP and redistribute the route from BGP.
- B. Configure BGP address family VPNv4.
- C. Configure LDP and redistribute the route from EIGRP.
- D. Configure IGP LDP synchronization
Answer: D
NEW QUESTION # 22
Refer to the exhibit:
Which statement about the status of the neighbor relationship between R1 and R2 is true?
- A. The neighbor relationship is up because R2 is level 1 and level 2 router.
- B. The neighbor relationship is down because the two routers are configured with different area types
- C. The neighbor relationship is down because the two routers are in the same subnet.
- D. The neighbor relationship is down because R2 is operating as a Level 1 router and the two routers are in different area
Answer: D
NEW QUESTION # 23
Refer to the exhibit:
A network engineer is implementing a BGP protocol. Which effect of the local-as keyword in this configuration is true?
- A. It enables peer 192.168.1.2 to establish a BGP relationship with R1 using AS 65112 and the VPNv4 address family
- B. It enables peer 192.168.1.2 to establish a BGP relationship with R1 using AS 65012 without additional configuration
- C. It enables peer 192.168.1.2 to establish a BGP relationship with R1 using AS 65112 without additional configuration.
- D. It enables peer 192.168.1.2 to establish a BGP relationship with R1 using AS 65012 and the VPNv4 address family
Answer: C
Explanation:
The local-as keyword is used in BGP configurations to change the local AS number that is used in the BGP OPEN message when establishing a BGP session with a specific neighbor. In this case, even though the router is configured with AS 65000, it will use AS 65112 when establishing a connection with neighbor 192.168.1.2 due to the local-as keyword configuration.

Additionally, the customer provided these VLAN to EVC mapping requirements:
* EVC 1 between CE-1 and CE-2 must be provisioned with C-VLAN 12 at the HQ location.
* EVC 2 between CE-1 and CE-3 must be provisioned with C-VLAN 13 at the HQ location.

Answer: A
NEW QUESTION # 27
Refer to the exhibit:
In which way does router R1 operate differently than router R2?
- A. R1 sends LSA type 2 only and R2 sends LSA type 1 only
- B. R1 sends LSA types 5 and 7, while R2 sends type 1, 2, and 7 LSAs
- C. R1 sends LSA type 2 only, while R2 sends type 1 and type 7 LSAs
- D. R1 sends LSA types 1 and 2, while R2 sends type 1. 2. and 7 LSAs
Answer: D
Explanation:
Router R1 is configured as a stub area with the "no-summary" option, which means it will not receive summary LSAs (Type 3) from the Area Border Router (ABR). It will only have Type 1 (Router LSAs) and Type 2 (Network LSAs) in its OSPF database for the area it belongs to. Router R2 is configured as an NSSA (Not So Stubby Area), which allows it to import AS external routes as Type-7 LSAs. These Type-7 LSAs can then be converted to Type-5 LSAs by the ABR when propagated into other areas. Therefore, R2 has Types 1,
2, and 7 LSAs in its OSPF database.
For more detailed information, please refer to the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) course materials, specifically the sections covering OSPF area types and LSA types.
NEW QUESTION # 28
Refer to the exhibit. A network engineer with an employee ID: 5086:72:817 is configuring a connection to manage CE1 from the OAM server on VLAN 100. PE1 must push S-VLAN tag 10 toward PE2 while forwarding traffic from CE1 to the OAM server. PE1 must push S-VLAN tag 20 toward PE2 while forwarding traffic from CE2 to the data traffic gateway. Which configuration must the engineer implement on PE2?
- A. Interface Ge0/0
encapsulation dot1q 100
rewrite ingress tag push dot1q 10 symmetric
Interface Ge0/1
encapsulation dot1q 200
rewrite ingress tag push dot1q 20 symmetric - B. Interface Ge0/1
encapsulation dot1q 10
rewrite ingress tag push dot1q 10 symmetric
Interface Ge0/0
encapsulation dot1q 20
rewrite ingress tag push dot1q 20 symmetric - C. Interface Ge0/1
encapsulation dot1q 100
rewrite ingress tag translate 1-to-1 dot1q 20 - D. Interface Ge0/1
encapsulation dot1q 100
rewrite ingress tag pop 10
rewrite ingress tag push 20
Answer: C
Explanation:
On PE2 you must map the incoming S-VLAN tags directly into the CE-VLAN. The one-to-one translate command does exactly that - any packet arriving with S-VLAN-20 is rewritten into C-VLAN-100 on the CE-facing subinterface.
PE2(config)# interface GigabitEthernet0/1
PE2(config-if)# encapsulation dot1q 100
PE2(config-if)# rewrite ingress tag translate 1-to-1 dot1q 20
This ensures that traffic PE1 has S-tagged with 20 (from CE2) is presented to the CE3/OAM server on VLAN-100.
NEW QUESTION # 29

NEW QUESTION # 30
Which statement about the Cisco MPLS TE forwarding adjacency feature is true?
- A. It enables the headend and tailend routers to establish a bidirectional tunnel
- B. It enables the tailend router to advertise routes to the headend router over the tunnel
- C. It enables the MPLS core to use EIGRP as the routing protocol
- D. It enables the Cisco MPLS TE tunnel to be advertised into the running IGP.
Answer: D
Explanation:
The Cisco MPLS TE forwarding adjacency feature allows a TE tunnel to be advertised into the IGP, effectively making the tunnel appear as a network link in the IGP topology. This integration helps in the optimal utilization of the TE tunnel by other routers for IP routing purposes.
NEW QUESTION # 31
Refer to the exhibit:
Router R1 and its peer R2 reside on the same subnet in the network, If does it make connections to R27
- A. R1 establishes UDP connections that are authenticated with a clear-text password
- B. R1 establishes UDP connections that are authenticated with an MD5 password
- C. R1 establishes TCP connections that are authenticated with an MD5 password
- D. R1 establishes TCP connections that are authenticated with a clear-text password
Answer: C
Explanation:
Router R1 establishes TCP connections that are authenticated with an MD5 password. In the context of BGP (Border Gateway Protocol), TCP is used for establishing connections, and MD5 passwords can be used for authentication to enhance security.
