Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q76-Q81):

NEW QUESTION # 76
In IS-IS, which two statements are correct about the designated intermediate system (DIS) on a multi-access network segment? (Choose two)

  • A. On the multi-access network, each router forms an adjacency to every other router on the segment
  • B. A router with a priority of 1 wins the DIS election over a router with a priority of 10.
  • C. On the multi-access network, each router only forms an adjacency to the DIS.
  • D. A router with a priority of 10 wins the DIS election over a router with a priority of 1.

Answer: C,D

Explanation:
Explanation
In IS-IS, a designated intermediate system (DIS) is a router that is elected on a multi-access network segment (such as Ethernet) to perform some functions on behalf of other routers on the same segment. A DIS is responsible for sending network link-state advertisements (LSPs), which describe all the routers attached to the network. These LSPs are flooded throughout a single area. A DIS also generates pseudonode LSPs, which represent the multi-access network as a single node in the link-state database. A DIS election is based on the priority value configured on each router's interface connected to the multi-access network. The priority value ranges from 0 to 127, with higher values indicating higher priority. The router with the highest priority becomes the DIS for the area (Level 1, Level 2, or both). If routers have the same priority, then the router with the highest MAC address is elected as the DIS. By default, routers have a priority value of 64. On a multi-access network, each router only forms an adjacency to the DIS, not to every other router on the segment. This reduces the amount of hello packets and LSP


NEW QUESTION # 77
Referring to the exhibit, which two statements are correct regarding the output shown in the exhibit? (Choose two.)

  • A. The multicast traffic is using the SPT.
  • B. The multicast group is an SSM group.
  • C. The multicast traffic is using the RPT.
  • D. The multicast group is an ASM group.

Answer: A,B

Explanation:
The group address is from SSM address block range (232.0.0.0 through 232.255.255.255).


NEW QUESTION # 78
Exhibit.

Referring to the exhibit, which path would traffic passing through R1 take to get to R4?

  • A. R1 -> R2 -> R3 -> R4
  • B. R1 -> R3 -> R4
  • C. R1 -> R2 -> R4
  • D. R1 -> R4

Answer: C

Explanation:
The OSPF cost is carried in the LSAs that are exchanged within an OSPF area. When a router calculates the cost to a destination it uses the cost of the exit interface of each router in the path to the destination.


NEW QUESTION # 79
Exhibit

The network shown in the exhibit is based on IS-IS
Which statement is correct in this scenario?

  • A. The NSEL byte for Area 0001 is 00.
  • B. The system IDofR1_2 is 192.168.16.1
  • C. The routers are using unnumbered interfaces
  • D. The area address is two bytes.

Answer: A

Explanation:
Explanation
IS-IS is an interior gateway protocol that uses link-state routing to exchange routing information among routers within a single autonomous system. IS-IS uses two types of addresses to identify routers and areas:
system ID and area address. The system ID is a unique identifier for each router in an IS-IS domain. The system ID is 6 octets long and can be derived from the MAC address or manually configured. The area address is a variable-length identifier for each area in an IS-IS domain. The area address can be 1 to 13 octets long and is composed of high-order octets of the address. An IS-IS instance may be assigned multiple area addresses, which are considered synonymous. Multiple synonymous area addresses are useful when merging or splitting areas in the domain1. In this question, we have a network based on IS-IS with four routers (R1_1, R1_2, R2_1, and R2_2) belonging to area 0001. The area address for area 0001 is 49.0001. The NSEL byte for area 0001 is the last octet of the address, which is 01. The NSEL byte stands for Network Service Access Point Selector (NSAP Selector) and indicates the type of service requested from the network layer2. Therefore, the correct statement in this scenario is that the NSEL byte for area 0001 is 01.

NEW QUESTION # 80
Exhibit.

Referring to the exhibit; the 10.0.0.0/24 EBGP route is received on R5; however, the route is being hidden.
What are two solutions that will solve this problem? (Choose two.)

  • A. Add the external interface prefix to the IGP routing tables
  • B. Add the internal interface prefix to the BGP routing tables.
  • C. On R4, create a policy to change the BGP next hop to 172.16.1.1 and apply it to IBGP as an export policy
  • D. On R4, create a policy to change the BGP next hop to itself and apply it to IBGP as an export policy

Answer: A,D

Explanation:
Explanation
the default behavior for iBGP is to propagate EBGP-learned prefixes without changing the next-hop. This can cause issues if the next-hop is not reachable via the IGP. One solution is to use the next-hop self command on R4, which will change the next-hop attribute to its own loopback address. This way, R5 can reach the next-hop via the IGP and install the route in its routing table.
Another solution is to add the external interface prefix (120.0.4.16/30) to the IGP routing tables of R4 and R5.
This will also make the next-hop reachable via the IGP and allow R5 to use the route. According to 2, this is a possible workaround for a pure IP network, but it may not work well for an MPLS network.
