NEW QUESTION # 79 
Click the Exhibit hutton.
You are configuring an interprovider Option C Layer 3 VPN to connect two customer sites.
Referring to the exhibit, which three statements are correct? (Choose three.)
Answer: A,C,E
Explanation:
Interprovider Option C for Layer 3 VPNs involves the use of Autonomous System Boundary Routers (ASBRs) to exchange labeled VPN-IPv4 routes between different Autonomous Systems (AS). This option requires BGP sessions between ASBRs, and the VPN routes are carried end-to-end using MPLS labels. Here' s a detailed analysis of the roles of different routers in this scenario:
1. **ASBR Routers**:
- ASBRs are responsible for exchanging VPN-IPv4 routes between different ASes.
- **A. ASBR routers maintain the internal routes from its own AS and the loopback addresses from the other AS PEs.**
- Correct. ASBRs maintain routes to internal destinations within their own AS, and they also need to know the loopback addresses of PEs in the other AS to set up the BGP sessions and MPLS tunnels.
2. **PE Routers**:
- PE routers are responsible for maintaining VPN routes and label information to forward VPN traffic correctly.
- **B. PE routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.**
- Correct. PE routers need to maintain:
- Internal routes within their AS for routing.
- Loopback addresses of other AS PEs for establishing MPLS LSPs.
- L3VPN routes to provide end-to-end VPN connectivity.
3. **P Routers**:
- P routers are the core routers that do not participate in BGP VPN routing but forward labeled packets based on MPLS labels.
- **C. P routers only maintain the internal routes from their own AS.**
- Correct. P routers maintain the internal routing information to forward packets within the AS and use MPLS labels for forwarding VPN packets. They do not maintain VPN routes or routes from other ASes.
4. **Incorrect Statements**:
- **D. P routers maintain the internal routes from its own AS and the loopback address from the other AS PEs.
**
- Incorrect. P routers do not need to maintain the loopback addresses of other AS PEs. They only maintain internal routing and MPLS label information.
- **E. ASBR routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.**
- Incorrect. ASBR routers do not maintain L3VPN routes. They exchange labeled VPN-IPv4 routes with other ASBRs and forward them to PE routers.
**Conclusion**:
The correct answers are:
**A. ASBR routers maintain the internal routes from its own AS and the loopback addresses from the other AS PEs.**
**B. PE routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.**
**C. P routers only maintain the internal routes from their own AS.**

NEW QUESTION # 80
A router running IS-IS is configured with an ISO address of 49.0001.00a0.c96b.c490.00.
Which part of this address is the system ID?
Answer: D
Explanation:
In IS-IS (Intermediate System to Intermediate System) routing, each router is identified by a unique ISO (International Organization for Standardization) address, also known as a Network Entity Title (NET). The NET consists of three parts:
1. **Area Identifier**: Indicates the area to which the router belongs.
2. **System Identifier**: Uniquely identifies the router within the area.
3. **NSAP Selector (NSEL)**: Typically set to 00 for a router, indicating the Network Service Access Point.
The format of the ISO address is `49.XXXX.YYYY.YYYY.ZZZZ.ZZZZ.00`, where:
- `49` is the AFI (Authority and Format Identifier) indicating a private address.
- `XXXX` is the Area Identifier.
- `YYYY.YYYY.YYYY` is the System Identifier.
- `ZZZZ.ZZZZ` is the NSAP Selector.
Given the address `49.0001.00a0.c96b.c490.00`:
- **Area Identifier**: `49.0001`
- **System Identifier**: `00a0.c96b.c490`
- **NSAP Selector**: `00`
**Explanation**:
- **A. 00a0.c96b.c490 is the system identifier**:
- Correct. The System Identifier in an ISO address is a 48-bit (6-byte) field used to uniquely identify the router. In this address, `00a0.c96b.c490` is the correct 6-byte System Identifier.
- **B. 0001.00a0.c96b.c490 is the system identifier**:
- Incorrect. This includes the Area Identifier as part of the System Identifier, which is not correct.
- **C. c96b.c490 is the system identifier**:
- Incorrect. This is only part of the System Identifier. The full System Identifier must be 6 bytes long.
- **D. c490 is the system identifier**:
- Incorrect. This is an incomplete and incorrect part of the System Identifier.
**Conclusion**:
The correct part of the address that represents the System Identifier is:
**A. 00a0.c96b.c490 is the system identifier.**
**References**:
- Juniper Networks Documentation on IS-IS: [IS-IS Configuration](https://www.juniper.net/documentation
/en_US/junos/topics/task/configuration/isis-configuring.html)
- ISO/IEC 10589, the IS-IS routing protocol standard.
NEW QUESTION # 81
You are responding to an RFP for a new MPLS VPN implementation. The solution must use LDP for signaling and support Layer 2 connectivity without using BGP. The solution must be scalable and support multiple VPN connections over a single MPLS LSP. The customer wants to maintain all routing for their private network.
In this scenario, which solution do you propose?
Answer: D
NEW QUESTION # 82
After a recent power outage, your manager asks you to investigate ways to automatically reduce the impact caused by suboptimal routing in your OSPF and OSPFv3 network after devices reboot.
Which three configuration statements accomplish this task? (Choose three.)
Answer: A,B,D
NEW QUESTION # 83
Exhibit
Referring to the exhibit, you are receiving the 192.168 0 0/16 route on both R3 and R4 from your EBGP neighbor You must ensure that R1 and R2 receive both BGP routes from the route reflector In this scenario, which BGP feature should you configure to accomplish this behavior?
Answer: C
Explanation:
BGP add-path is a feature that allows the advertisement of multiple paths through the same peering session for the same prefix without the new paths implicitly replacing any previous paths. This behavior promotes path diversity and reduces multi-exit discriminator (MED) oscillations. BGP add-path is implemented by adding a path identifier to each path in the NLRI. The path identifier can be considered as something similar to a route distinguisher in VPNs, except that a path ID can apply to any address family. Path IDs are unique to a peering session and are generated for each network3. In this question, we have a route reflector (RR) that receives two routes for the same prefix (192.168.0.0/16) from an EBGP neighbor. By default, the RR will only advertise its best path to its clients (R1 and R2). However, we want R1 and R2 to receive both routes from the RR. To achieve this, we need to configure BGP add-path on the RR and enable it to send multiple paths for the same prefix to its clients.
