Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q35-Q40):

NEW QUESTION # 35

Click the Exhibit button.
Referring to the exhibit, you must provide VRF Internet access over a single connection for VPN-A Site 1, which connects to PE-1.
Which two statements are correct in this scenario? (Choose two.)

  • A. You do not need to use the RIB group to move interface routes from the inet. o table to the VPN-A. inet.
    0 table.
  • B. You do not need to use the RIB group default route, which is learned through BGP, from the inet. o table to the VPN-A. inet. 0 table.
  • C. You must use the RIB group to move a default route, which is learned through BGP, from the inet. o table to the VPN-A. inet. 0 table.
  • D. You must use the RIB group to move interface routes from the inet . 0 table to the VPN-A. inet. 0 table.

Answer: A,C

Explanation:
In the provided exhibit, the configuration involves using a RIB (Routing Information Base) group to facilitate internet access for VPN-A Site 1 through PE-1. The goal is to provide VRF Internet access over a single connection.
1. **Understanding RIB Groups**:
- RIB groups allow for the import and export of routes between different routing tables.
- In this scenario, we have two RIBs: `inet.0` (the main routing table) and `VPN-A.inet.0` (the VRF-specific routing table).
2. **Statement Analysis**:
- **A. You must use the RIB group to move a default route, which is learned through BGP, from the inet.0 table to the VPN-A.inet.0 table.**
- Correct. To provide Internet access to VPN-A, the default route (0.0.0.0/0) learned via BGP in the `inet.0` table must be made available in the `VPN-A.inet.0` table. This is done using the RIB group to import the default route.
- **B. You do not need to use the RIB group to move interface routes from the inet.0 table to the VPN-A.inet.0 table.**
- Correct. Interface routes (connected routes) are typically directly added to both the global and the VRF routing tables without needing a RIB group. These routes are known to the VRF because the interfaces are part of the VRF configuration.
- **C. You do not need to use the RIB group default route, which is learned through BGP, from the inet.0 table to the VPN-A.inet.0 table.**
- Incorrect. As discussed, the default route needs to be imported into the VRF's routing table using a RIB group to enable Internet access for the VRF.
- **D. You must use the RIB group to move interface routes from the inet.0 table to the VPN-A.inet.0 table.**
- Incorrect. Interface routes are directly associated with the VRF interfaces and are automatically known to the VRF routing table. There is no need to use a RIB group for these routes.
**Conclusion**:
The correct answers are:
**A. You must use the RIB group to move a default route, which is learned through BGP, from the inet.0 table to the VPN-A.inet.0 table.**
**B. You do not need to use the RIB group to move interface routes from the inet.0 table to the VPN-A.inet.0 table.**

NEW QUESTION # 36
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 only forms an adjacency to the DIS.
  • B. On the multi-access network, each router forms an adjacency to every other router on the segment.
  • C. A router with a priority of 1 wins the DIS election over a router with a priority of 10.
  • D. A router with a priority of 10 wins the DIS election over a router with a priority of 1.

Answer: B,D


NEW QUESTION # 37
Exhibit

You want to implement the BGP Generalized TTL Security Mechanism (GTSM) on the network Which three statements are correct in this scenario? (Choose three)

  • A. You can implement BGP GTSM between R2, R3, and R4
  • B. You can implement BGP GTSM between R2 and R1.
  • C. BGP GTSM requires a TTL of 255 to be configured between neighbors.
  • D. BGP GTSM requires a firewall filter to discard packets with incorrect TTL.
  • E. BGP GTSM requires a TTL of 1 to be configured between neighbors.

Answer: B,C,D

NEW QUESTION # 38

  • A. You do not need to use the RIB group default route, which is learned through BGP, from the inet. o table to the VPN-A. inet. 0 table.
  • B. You must use the RIB group to move a default route, which is learned through BGP, from the inet. o table to the VPN-A. inet. 0 table.
  • C. You do not need to use the RIB group to move interface routes from the inet. o table to the VPN-A.
    inet. 0 table.
  • D. You must use the RIB group to move interface routes from the inet . 0 table to the VPN-A. inet. 0 table.

NEW QUESTION # 39
Which two statements are correct regarding the PIM DR in a PIM-SM domain? (Choose two.)

  • A. The receiver DR sends PIM join and PIM prune messages from the receiver network toward the RP.
  • B. The source DR sends PIM register messages from the source network to the RP.
  • C. If the DR priorities match, the router with the lowest IP address is selected as the DR.
  • D. By default, PIM DR election is performed on point-to-point links.

Answer: A,B

Explanation:
In PIM-SM (Protocol Independent Multicast - Sparse Mode), the Designated Router (DR) plays a crucial role in multicast forwarding. The DR is responsible for various tasks depending on whether it is connected to the source or the receiver. Let's analyze each statement regarding the PIM DR in a PIM-SM domain.
1. **Statement A: The source DR sends PIM register messages from the source network to the RP.**
- Correct. In PIM-SM, the DR on the source's local network is responsible for encapsulating multicast packets in PIM Register messages and sending them to the Rendezvous Point (RP). This process ensures that the RP is aware of active sources.
2. **Statement B: If the DR priorities match, the router with the lowest IP address is selected as the DR.**
- Incorrect. The correct rule is that if the DR priorities match, the router with the **highest** IP address is selected as the DR. The election process first compares priorities; if priorities are equal, the IP addresses are compared to select the DR.
3. **Statement C: The receiver DR sends PIM join and PIM prune messages from the receiver network toward the RP.**
- Correct. In PIM-SM, the DR on the receiver's local network sends PIM Join messages toward the RP to join the multicast distribution tree. Similarly, it sends PIM Prune messages to leave the tree when there are no interested receivers.
4. **Statement D: By default, PIM DR election is performed on point-to-point links.**
- Incorrect. By default, PIM DR election is performed on multi-access networks (e.g., Ethernet). On point-to- point links, there is no need for a DR election as there are only two routers involved.
**Conclusion**:
The correct statements regarding the PIM DR in a PIM-SM domain are:
**A. The source DR sends PIM register messages from the source network to the RP.**
**C. The receiver DR sends PIM join and PIM prune messages from the receiver network toward the RP.**
**References**:
- Juniper Networks Documentation on PIM-SM: [PIM-SM Overview](https://www.juniper.net/documentation
/en_US/junos/topics/concept/pim-sparse-mode-overview.html)
- RFC 7761, Protocol Independent Multicast - Sparse Mode (PIM-SM): [RFC 7761](https://tools.ietf.org/html
/rfc7761) which details the PIM-SM protocol, including DR roles and election procedures.
