Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q66-Q71):

NEW QUESTION # 66
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: A,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 # 67
Refer to the exhibit.

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 must use the RIB group to move interface routes 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. o table to the VPN-A. inet. 0 table.
  • C. 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.
  • D. 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.

Answer: B,D

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 # 68
When building an interprovider VPN, you notice on the PE router that you have hidden routes which are received from your BGP peer with family inet labeled-unica3t configured.
Which parameter must you configure to solve this problem?

  • A. Under the family inet labeled-unicast hierarchy, add the explicit null parameter.
  • B. Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.
  • C. Under the protocols ospf hierarchy, add the traffic-engineering parameter.
  • D. Under the protocols mpls hierarchy, add the traffic-engineering parameter

Answer: B

Explanation:
Explanation
The resolve-vpn parameter is a BGP option that allows a router to resolve labeled VPN-IPv4 routes using unlabeled IPv4 routes received from another BGP peer with family inet labeled-unicast configured. This option enables interprovider VPNs without requiring MPLS labels between ASBRs or using VRF tables on ASBRs. In this scenario, you need to configure the resolve-vpn parameter under [edit protocols bgp group external family inet labeled-unicast] hierarchy level on both ASBRs.


NEW QUESTION # 69
Exhibit

Referring to the exhibit, PE-1 and PE-2 are getting route updates for VPN-B when neither of them service that VPN Which two actions would optimize this process? (Choose two.)

  • A. Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement on the PEs.
  • B. Configure the family route-target statement on the PEs.
  • C. Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement on the RR.
  • D. Configure the family route-target statement on the RR.

Answer: C,D

Explanation:
BGP route target filtering can be configured on PE devices or on route reflectors (RRs). Configuring BGP route target filtering on RRs is more efficient and scalable, as it reduces the number of BGP sessions and updates between PE devices. To configure BGP route target filtering on RRs, the following steps are required:
Configure the family route-target statement under the BGP group or neighbor configuration on the RRs. This enables the exchange of the route-target address family between the RRs and their clients (PE devices).
Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement under the routing-options configuration on the RRs. This enables the RRs to resolve next hops for VPN routes using the inet.0 routing table.


NEW QUESTION # 70
Exhibit

Click the Exhibit button-Referring to the exhibit, which two statements are correct about BGP routes on R3 that are learned from the ISP-A neighbor? (Choose two.)

  • A. By default, the next-hop value for these routes is not changed by ISP-A before being sent to R3.
  • B. All BGP attribute values must be removed before receiving the routes.
  • C. The next-hop value for these routes is changed by ISP-A before being sent to R3.
  • D. The BGP local-preference value that is used by ISP-A is not advertised to R3.

Answer: C,D

Explanation:
Analyzing the Exhibit
The diagram represents BGP peering between:
AS 65512 (Enterprise Network)
AS 65511 (ISP-A)
R3 and R4 are peering with ISP-A using EBGP.
R1, R2, R3, and R4 are peering within AS 65512 using IBGP.
Understanding BGP Route Behavior
Option A: "By default, the next-hop value for these routes is not changed by ISP-A before being sent to R3." ❌ Incorrect!
EBGP behavior: When a BGP route is advertised via EBGP, the next-hop IP is changed to the router's own IP by default.
Since ISP-A is advertising routes via EBGP to R3, the next-hop is changed to ISP-A's IP.
Thus, this statement is incorrect.
Option B: "The BGP local-preference value that is used by ISP-A is not advertised to R3." ✅ Correct!
BGP Local Preference (LOCAL_PREF) is an IBGP-only attribute.
Local Preference is NOT shared over EBGP because it is used within an AS to influence route selection.
ISP-A will not send LOCAL_PREF to R3, as R3 is in a different AS.
Thus, this statement is correct.
Option C: "All BGP attribute values must be removed before receiving the routes." ❌ Incorrect!
BGP does not remove all attributes when advertising routes. Some attributes are modified (e.g., next-hop, AS-PATH), but others (like MED, community) may be preserved.
Thus, this statement is incorrect.
Option D: "The next-hop value for these routes is changed by ISP-A before being sent to R3." ✅ Correct!
As per default EBGP behavior, the next-hop is changed when a route is advertised to an EBGP peer.
This means ISP-A changes the next-hop to its own IP before sending it to R3.
Thus, this statement is correct.
Final answer:
✅ B. The BGP local-preference value that is used by ISP-A is not advertised to R3.
✅ D. The next-hop value for these routes is changed by ISP-A before being sent to R3.
Verification from Juniper Documentation:
Juniper BGP Configuration Guide confirms that LOCAL_PREF is not advertised over EBGP.
RFC 4271 (BGP-4) specifies that next-hop is changed by default when advertising routes via EBGP.
