Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q88-Q93):

NEW QUESTION # 88
Exhibit

R4 is directly connected to both RPs (R2 and R3) R4 is currently sending all ,o,ns upstream to R3 but you want all joins to go to R2 instead Referring to the exhibit, which configuration change will solve this issue?

A. Change the default route in inet.2 on R4 from R3 as the next hop to R2
B. Change the bootstrap priority on R2 to be higher than R3
C. Change the local address on R2 to be higher than R3.
D. Change the group-range to be more specific on R2 than R3.

Answer: D

NEW QUESTION # 89
Exhibit

A network is using IS-IS for routing.
In this scenario, why are there two TLVs shown in the exhibit?

A. Both IPv4 and IPv6 are being used in the topology
B. The interface specified a metric of 100 for L2.
C. Wide metrics have specifically been requested
D. There are both narrow and wide metric devices in the topology

Answer: D

Explanation:
TLVs are tuples of (Type, Length, Value) that can be advertised in IS-IS packets. TLVs can carry different kinds of information in the Link State Packets (LSPs). IS-IS supports both narrow and wide metrics for link costs. Narrow metrics use a single octet to encode the link cost, while wide metrics use three octets. Narrow metrics have a maximum value of 63, while wide metrics have a maximum value of 16777215. If there are both narrow and wide metric devices in the topology, IS-IS will advertise two TLVs for each link: one with the narrow metric and one with the wide metric. This allows backward compatibility with older devices that only support narrow metrics12.

NEW QUESTION # 90

Click the Exhibit button.
You have an EVI implemented between PE-1, PE-2, and PE-3 to allow communication between CE-1 and CE-2. CE-2 receives unicast traffic from CE-1 on both links to PE-2 and PE-3. When CE-1 sends broadcast traffic, CE-2 receives it on only one of the multihomed links.
Referring to the exhibit, which EVPN route type enables this behavior?

A. Type 3
B. Type 2
C. Type 4
D. Type 1

Answer: A

Explanation:
In the context of Ethernet VPN (EVPN) and the behavior described in the exhibit, it's essential to understand the different EVPN route types and their specific functionalities. Here, CE-2 is receiving unicast traffic on both of its multihomed links to PE-2 and PE-3, but broadcast traffic is received only on one of these links.
**Explanation of EVPN Route Types**:
1. **Type 1 (Ethernet Auto-Discovery Routes)**:
- These routes are used for auto-discovery of Ethernet segments and for advertising VLAN membership.
- They do not directly influence the behavior described in the question.
2. **Type 2 (MAC/IP Advertisement Routes)**:
- These routes are used to advertise MAC addresses and IP-to-MAC bindings within the EVPN.
- They handle unicast traffic forwarding and are crucial for populating the MAC address tables on the PE devices.
- While important, they do not explain the selective broadcast behavior.
3. **Type 3 (Inclusive Multicast Ethernet Tag Routes)**:
- These routes are used to build multicast distribution trees for delivering broadcast, unknown unicast, and multicast (BUM) traffic.
- They ensure that BUM traffic is sent only once per Ethernet segment, preventing duplicate frames from being sent to multihomed CEs.
- This aligns with the behavior described where CE-2 receives broadcast traffic on only one link to prevent duplication.
4. **Type 4 (Ethernet Segment Routes)**:
- These routes are used to advertise the presence of an Ethernet segment and are crucial for Designated Forwarder (DF) election processes in multihoming scenarios.
- While relevant to multihoming, they are not directly responsible for the selective broadcast behavior.
**Conclusion**:
The behavior described, where CE-2 receives broadcast traffic on only one of its multihomed links, is controlled by Type 3 routes. These routes are specifically designed to handle inclusive multicast and broadcast traffic efficiently in EVPN environments, ensuring that such traffic is not duplicated across multiple links to the same CE.

NEW QUESTION # 91
You want to ensure that a single-area OSPF network will be loop free.
In this scenario, what are two requirements that satisfy this requirement? (Choose two.)

A. The Shortest Path First algorithm must prune looped paths.
B. Nodes within an area must connect in a full mesh.
C. The DR/BDR ensures that each node within an area has the same information in their LSDBs.
D. All nodes within an area must have the same information in their LSDBs.

Answer: A,D

NEW QUESTION # 92
Exhibit

R1 and R8 are not receiving each other's routes
Referring to the exhibit, what are three configuration commands that would solve this problem? (Choose three.)

A. Configure loops and advertise-peer-as on routers in AS 64497 and AS 64450.
B. Configure remove-private on advertisements from AS 64497 toward AS 64498.
C. Configure as-override on advertisement from AS 64500 toward AS 64512.
D. Configure remove-private on advertisements from AS 64500 toward AS 64499.
E. Configure loops on routers in AS 65412 and advertise-peer-as on routers in AS 64498.

Answer: B,C,D
