Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q67-Q72):

NEW QUESTION # 67
Exhibit

Which two statements about the output shown in the exhibit are correct? (Choose two.)

  • A. The connection has not flapped since it was initiated.
  • B. The PE is attached to a single local site.
  • C. There has been a VLAN ID mismatch.
  • D. The PE router has the capability to pop flow labels

Answer: A,B

Explanation:
The output is from the show l2vpn connections command on a Juniper router. This command is used to verify the status of Layer 2 VPN (L2VPN) pseudowires between Provider Edge (PE) routers.
Breakdown of Key Information:
* Instance: vpn-A
* This is the L2VPN instance being monitored.
* Connection Status (St)
* The connection status is "Up", meaning the pseudowire is operational.
* Local Site: CE1-2 (2)
* The PE router is attached to a single local site (CE1-2).
* Uptime & Connection Flaps
* The output shows the last time the connection was up:
Time last up: Apr 11 14:35:27 2020
* The "# Up trans" value is 1, meaning this connection has been established once and has not flapped since it was initiated.
* VLAN ID Mismatch Check
* The legend includes "VM - VLAN ID mismatch", but this status is not present in the connection output.
* This means there is NO VLAN ID mismatch.
* Flow Labels
* The Flow Label Transmit is No, and the Flow Label Receive is No.
* This means the PE router does NOT have the capability to pop flow labels.


NEW QUESTION # 68
Exhibit

Which two statements are true about the OSPF adjacency displayed in the exhibit? (Choose two.)

  • A. There is a mismatch in the poll interval parameter between routers R1 and R2.
  • B. There is a mismatch in the dead interval parameter between routers R1 and R2.
  • C. There is a mismatch in the hello interval parameter between routers R1 and R2
  • D. There is a mismatch in the OSPF hold timer parameter between routers R1 and R2.

Answer: B,C

Explanation:
The hello interval is the time interval between two consecutive hello packets sent by an OSPF router on an interface. The dead interval is the time interval after which a neighbor is declared down if no hello packets are received from it. These parameters must match between two OSPF routers for them to form an adjacency. In the exhibit, router R1 has a hello interval of 10 seconds and a dead interval of 40 seconds, while router R2 has a hello interval of 30 seconds and a dead interval of 120 seconds. This causes a mismatch and prevents them from becoming neighbors23.


NEW QUESTION # 69

Click the Exhibit button.
Referring to the exhibit, the PE-to-CE protocol being used is OSPF for the L3VPN. Also, there is an OSPF neighborship between CE-1 and CE-2.
Which statement is correct in this situation?

  • A. Hosts at Site-1 will reach hosts at Site-2 through the CE-1 and CE-2 link by default.
  • B. You must set a high metric on the CE-1 to PE-1 link for hosts at Site-1 to use the CE-1 to CE-2 link to reach hosts at Site-2.
  • C. You must set a high metric on the CE-1 to CE-2 link for hosts at Site-1 to use the L3VPN to reach hosts at Site-2.
  • D. Hosts at Site-1 will reach hosts at Site-2 through the L3VPN by default.

Answer: A

Explanation:
In the exhibit, the PE-to-CE protocol used is OSPF, and there is an OSPF neighborship between CE-1 and CE-2 within the same Area 0. Let's analyze the default OSPF routing behavior in this setup to determine the correct statement.
1. **OSPF Neighborship**:
- CE-1 and CE-2 have an OSPF neighborship directly within Area 0.
- OSPF prefers intra-area routes over inter-area and external routes.
2. **Default Routing Behavior**:
- Since CE-1 and CE-2 are directly connected through an OSPF link within the same area, OSPF will prefer this direct intra-area path over any other paths learned via the PE routers and the L3VPN.
- This is because intra-area routes have a lower metric compared to inter-area or external routes.
3. **Metric Considerations**:
- By default, OSPF will route traffic between Site-1 and Site-2 through the direct link between CE-1 and CE-2, unless the link's metric is artificially increased to make it less preferable.
- There is no need to adjust metrics for the CE-1 to PE-1 link to prefer the CE-1 to CE-2 path, as OSPF already prefers direct intra-area paths.
**Conclusion**:
Given the default behavior of OSPF and the topology shown in the exhibit, the correct statement is:
**B. Hosts at Site-1 will reach hosts at Site-2 through the CE-1 and CE-2 link by default.**

NEW QUESTION # 70
In which two ways does OSPF prevent routing loops in multi-area networks? (Choose two.)

  • A. All areas are required to connect to area 0.
  • B. All areas are required to connect as a full mesh.
  • C. The SPF algorithm prunes looped paths within an area.
  • D. The LFA algorithm prunes all looped paths within an area.

Answer: A,C


NEW QUESTION # 71
Refer to the exhibit.

Click the Exhibit button.
Referring to the exhibit, which two statements are true? (Choose two.)

  • A. The multihop configuration is used for load balancing.
  • B. This route is learned from two different AS numbers.
  • C. This route is learned from the same AS number.
  • D. The multipath configuration is used for load balancing.

Answer: C,D

Explanation:
In the exhibit, the output of the `show route protocol bgp` command is shown for the prefix `172.16.20.4/30`. Let's analyze the provided BGP routing table to determine which statements are correct.
1. **AS Path Analysis**:
- The AS path for the route `172.16.20.4/30` is shown as `2 I`.
- This indicates that the route was learned from AS 2 and it is an internal (iBGP) route within the same AS.
2. **Multiple Paths**:
- The route has two next-hop IP addresses: `10.0.18.2` via interface `ge-1/0/4.0` and `10.0.19.2` via interface `ge-1/0/5.0`.
- This indicates that BGP multipath is configured, which allows multiple equal-cost paths to be used for load balancing.
- BGP multipath must be explicitly configured to use multiple paths for the same prefix.
3. **Multihop vs. Multipath**:
- **Multihop Configuration**: This is typically used for establishing BGP sessions with peers that are not directly connected. It is not related to load balancing.
- **Multipath Configuration**: This is used to enable load balancing across multiple paths for the same prefix, which is the case here.
**Conclusion**:
Given the above analysis:
- **C. This route is learned from the same AS number**: Correct. The AS path `2 I` indicates the route was learned from the same AS number (AS 2).
- **D. The multipath configuration is used for load balancing**: Correct. The presence of multiple next-hops indicates that BGP multipath is configured for load balancing.
Thus, the correct answers are:
**C. This route is learned from the same AS number.**
**D. The multipath configuration is used for load balancing.**
