QUESTION NO: 4
On an MPLS network where LDP is used to establish LSPs, a transit node directly connected to the ingress node that sends a label request distributes labels to the ingress node only after receiving a label mapping message from the egress node. In this case, which of the following is the correct combination of the label advertisement mode and label distribution control mode?

QUESTION NO: 5
In the preparation phase of a migration project , the software and hardware need to be checked. Match the operation objects in the preparation phase with the corresponding operation contents.
In the preparation phase of a migration project , the software and hardware need to be checked. Match the operation objects in the preparation phase with the corresponding operation contents.
Correct Answer:
Explanation:
Network cable # Use a tester to check connectivity.
Device version file # Check the size of the software package and check whether the file matches the device model.
Board # Install the board on a device that is not connected to the network and observe the running status of the device.
License # Check whether the license is in the validity period to prevent device functions from being affected.
Migration personnel list # Check whether responsibilities and permissions are clearly assigned.
Comprehensive and Detailed In-Depth Explanation:
1. Network Cable - Connectivity Testing:
* Before starting a migration project, all network cables should be tested for physical connectivity issues
.
* Network testers can be used to detect any breaks, shorts, or incorrect wiring.
* Ensuring proper connectivity avoids delays and troubleshooting issues during the migration.
2. Device Version File - Software Compatibility Check:
* Firmware and software versions must be verified before upgrading or migrating network devices.
* The device version file should match the model and hardware specifications to avoid compatibility issues.
* If incorrect software is used, the device may not function properly or could become inoperable.
3. Board - Installation and Hardware Verification:
* Before installing new hardware modules (boards, line cards, etc.) into a production environment, they should be tested in isolation .
* Testing ensures the board is operational and does not introduce faults into the system.
* If a board is faulty, it can cause device failure or unexpected behavior in the migration.
4. License - Validity and Activation Check:
* Some network devices require licenses for full functionality (e.g., advanced routing, security features).
* If a license is expired or missing, critical functions may be disabled after migration.
* Checking license status in advance prevents unexpected downtime or service disruptions.
5. Migration Personnel List - Roles and Responsibilities Assignment:
* Large network migrations require clear responsibility assignments for each team member.
* A migration personnel list ensures that everyone knows their role, tasks, and permissions .
* Proper coordination avoids miscommunication, errors, and project delays.
Key Takeaways:
# Network cables should be tested for connectivity.
# Software versions should match the hardware model to prevent incompatibility.
# Hardware boards should be tested before installing into production.
# Licenses should be verified to prevent service disruptions.
# Migration personnel roles should be clearly defined for smooth execution.

QUESTION NO: 6
On the OSPFv3 network shown in the figure, area 1 is a common area. R2 generates an Inter-Area-Prefix- LSA to describe the routes of a network segment in the area. Such an LSA exists in both area 0 and area 1.

QUESTION NO: 7
On a stable network that requires fast route convergence, you can change the value of the interval at which OSPF LSAs are updated to 0 so that topology or route changes can be immediately advertised on the network through LSAs, which speeds up route convergence.

QUESTION NO: 10
On the network shown in the figure, R1 and R2 cannot establish an EBGP peer relationship through directly connected interfaces. To locate this fault, a network engineer checks BGP configurations on R1 and R2, as shown in the figure. Based on these configurations, it can be determined that the fault cause is the inconsistent router IDs and interface IP addresses.
