Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q30-Q35):

NEW QUESTION # 30
Your organization manages a Layer 3 VPN for multiple customers To support advanced route than one BGP community on advertised VPN routes to remote PE routers.
Which routing-instance configuration parameter would support this requirement?

A. vrf-target import
B. vrf-target export
C. vrf-export
D. vrf-import

Answer: B

Explanation:
The vrf-target export parameter is used to specify one or more BGP extended community attributes that are attached to VPN routes when they are exported from a VRF routing instance to remote PE routers. This parameter allows you to control which VPN routes are accepted by remote PE routers based on their import policies. You can specify more than one vrf-target export value for a VRF routing instance to support advanced route filtering or route leaking scenarios.

NEW QUESTION # 31
Exhibit

Referring to the exhibit, what do the brackets [ ] in the AS path identify?

A. They identify an AS set, which are groups of AS numbers in which the order does not matter
B. They identify the local AS number associated with the AS path if configured on the router, or if AS path prepending is configured
C. They identify that the autonomous system number is incomplete and awaiting more information from the BGP protocol.
D. They identify that a BGP confederation is being used to ensure that there are no routing loops.

Answer: B

NEW QUESTION # 32
Exhibit.

Referring to the exhib.t, what must be changed to establish a Level 1 adjacency between routers R1 and R2?

A. Change the level 1 disable parameter under the R2 protocols isis interface ge-1/2/3 .0 hierarchy to the level 2 disable parameter
B. Add IP addresses to the interface ge-l/2/3 unit 0 family iso hierarchy on both R1 and R2.
C. Remove the level i disable parameter under the R2 protocols isis interface loo . 0 configuration hierarchy.
D. Change the level l disable parameter under the R1 protocols isis interface lo0.0 hierarchy to the level 2 disable parameter.

Answer: C

Explanation:
IS-IS routers can form Level 1 or Level 2 adjacencies depending on their configuration and network topology.
Level 1 routers are intra-area routers that share the same area address with their neighbors. Level 2 routers are inter-area routers that can connect different areas. Level 1-2 routers are both intra-area and inter-area routers that can form adjacencies with any other router.
In the exhibit, R1 and R2 are in different areas (49.0001 and 49.0002), so they cannot form a Level 1 adjacency. However, they can form a Level 2 adjacency if they are both configured as Level 1-2 routers. R1 is already configured as a Level 1-2 router, but R2 is configured as a Level 1 router only, because of the level 1 disable command under the lo0.0 interface. This command disables Level 2 routing on the loopback interface, which is used as the router ID for IS-IS.
Therefore, to establish a Level 1 adjacency between R1 and R2, the level 1 disable command under the R2 protocols isis interface lo0.0 hierarchy must be removed. This will enable Level 2 routing on R2 and allow it to form a Level 2 adjacency with R1.

NEW QUESTION # 33
You have an L2VPN connecting two CEs across a provider network that runs OSPF. You have OSPF configured on both CEs.
Which two statements are correct in this scenario? (Choose two.)

A. OSPF neighborship is formed between the two CEs.
B. The CE and PE OSPF areas can be different.
C. The CE and PE OSPF areas must match.
D. OSPF neighborship is formed between the CEs and PEs.

Answer: A,B

Explanation:
In an L2VPN scenario, the provider network connects two customer edge (CE) devices across a Layer 2 virtual private network. Let's analyze how OSPF operates in this setup.
1. **OSPF Neighborship in L2VPN**:
- An L2VPN provides a Layer 2 connection between two sites, making it transparent to Layer 3 protocols like OSPF. This means the CEs can form OSPF adjacencies directly with each other as if they were on the same local network.
2. **OSPF Configuration on CEs and PEs**:
- **Statement A: OSPF neighborship is formed between the CEs and PEs**:
- Incorrect. In an L2VPN, the provider's network is transparent to the OSPF running on the CEs. OSPF neighborship forms directly between the CEs, not between the CEs and PEs.
- **Statement B: The CE and PE OSPF areas can be different**:
- Correct. Since OSPF adjacencies form directly between the CEs and not between CEs and PEs, the OSPF areas on the CEs and PEs can be different. The provider network acts as a transparent bridge, and OSPF doesn't see the PEs.
- **Statement C: The CE and PE OSPF areas must match**:
- Incorrect. As noted above, because the OSPF neighborship forms directly between the CEs, the OSPF areas on the CEs and PEs do not need to match.
- **Statement D: OSPF neighborship is formed between the two CEs**:
- Correct. The L2VPN makes the connection between the two CEs appear as a direct Layer 2 link, allowing them to form an OSPF adjacency directly.
**Conclusion**:
Given the above analysis, the correct statements are:
**B. The CE and PE OSPF areas can be different.**
**D. OSPF neighborship is formed between the two CEs.**

NEW QUESTION # 34
Which two statements are correct regarding the PIM DR in a PIM-SM domain? (Choose two.)

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

Answer: A,D

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.
