Click the Exhibit button. In the exhibit, all routers are sending routes to Router B
Which routes will be advertised from Router B to Router D?
- A. BGP routes learned from Router A only
- B. BGP routes learned from Routers A, C and E only
- C. BGP routes learned from Router E only

NEW QUESTION # 169
Click the Exhibit button.
Referring to the exhibit, from which device(s) does R3 learn about Route X?
- A. R2 only
- B. both R2 and R1
- C. directly from the router in AS 64502
- D. R1 only
Answer: A
Explanation:
R2 can not forward IBGP learned routes to another IBGP neighbor correct R3 will learn about Route X from R2 only. R1 is in a separate AS and Route X is advertised to R2 through eBGP. R2 will then advertise the route to R3 using iBGP. R3 cannot learn routes directly from another AS without having a direct eBGP session with that AS.References:

NEW QUESTION # 174
Exhibit
The exhibit shows a topology with 1 Gbps interfaces between routers, and four RSVP LSPs operating with the respective bandwidth reservations.
Which path will be selected for a new LSP from R4 to R6 with a bandwidth reservation of 400 Mbps?
- A. R4 -> R1 -> R2 -> R5 -> R6
- B. R4 -> R5 -> R2 -> R3 -> R6
- C. R4 -> R1 -> R2 -> R3 -> R6
- D. R4 -> R5 -> R6
Answer: A
Explanation:
Considering the bandwidth reservations shown, the only path from R4 to R6 that has sufficient available bandwidth for a new LSP with 400 Mbps reservation is via R1, R2, and R5. This is because the R4-R5 direct link and the R4-R1-R2-R3-R6 path do not have enough unreserved bandwidth to accommodate an additional
400 Mbps LSP.

- D. Enable traffic engineering for the OSPF protocol.
Answer: B
NEW QUESTION # 177
You are asked to create connections between routing instances on the same Junos device and route between the connected Instances. What are two ways to accomplish this task? (Choose two.)
- A. Use an IRB interface.
- B. Use physical interfaces.
- C. Use logical tunnel interfaces.

NEW QUESTION # 178
Which two steps are required to enable MPLS on a physical interface in Junos? (Choose two.)
- A. Add the interface under protocols mpls.
- B. Add the loopback interface under protocols mpls.
- C. Add family mpls on the interface.
- D. Add family mpls on the loopback interface.
Answer: A,C
Explanation:
To enable MPLS on a physical interface in Junos, the family mpls statement must be added to the interface configuration. Additionally, the interface itself must be specifiedunder the protocols mpls section of the configuration.References:

Answer: D
NEW QUESTION # 180
You are implementing traffic engineering in your MPLS network. You must ensure that the MPLS routes are used to traverse your network. Your solution should not affect IGP routes in your route tables.
In this scenario, which traffic engineering setting will accomplish this behavior?
- A. mpls-forwarding
- B. bgp-igp-both-ribs
- C. bgp-igp
- D. bgp
Answer: D
Explanation:
bgp-On BGP destinations only. Ingress routes are installed in the inet.3 routing table.
bgp-igp-On both BGP and IGP destinations. Ingress routes are installed in the inet.0 routing table. If IGP shortcuts are enabled, the shortcut routes are automatically installed in the inet.0 routing table.
bgp-igp-both-ribs-On both BGP and IGP destinations. Ingress routes are installed in the inet.0 and inet.3 routing tables. This option is used to support VPNs.
mpls-forwarding-On both BGP and IGP destinations. Use ingress routes for forwarding only, not for routing.
NEW QUESTION # 181
Click the Exhibit button. Which two topologies shown in the exhibit could be implemented without a spanning-tree protocol? (Choose two.)
- A. ring
- B. star
- C. mesh
- D. tree
Answer: B,D
NEW QUESTION # 182
Exhibit
The routers shown in the exhibit ate configured for segment routing.
In this scenario, what is the adjacency SIO that Router B advertises to Router A?
- A. 10.1.1.2
- B. 10.1.1.1
- C. 0
- D. 1
Answer: C
Explanation:
The adjacency SID in segment routing is advertised by one router to inform another about the label that should be used to forward traffic to it over a particular link. In this scenario, Router B would advertise an adjacency SID to Router A, which would be usedby Router A to forward traffic to Router B. Based on the exhibit, the adjacency SID that Router B advertises to Router A would be 12.
