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.

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.

On the network shown in the figure, OSPF runs on R1, R2, and R3, and OSPF BFD is enabled. R1 and R3 use loopback interfaces to establish an iBGP peer relationship. If GE0/0/1 of R2 is shut down, which of the following is the longest period after which the BGP peer relationship of R1 will change from Up to Down?

• A. 180s
• B. 60s
• C. 40s
• D. 3s

A network engineer provides a troubleshooting report after rectifying a fault. The actual network is simplified into the one shown in the figure, where R1 and R2 both have OSPF enabled and function as the gateways of PC1 and PC2, respectively .
Given this, which of the following statements are true?

Network Topology:
* R1:
* Interface GE0/0/0 : 10.0.12.1/24 (Connected to R2)
* Interface GE0/0/1 : 192.168.1.1/24 (Gateway for PC1)
R2:
* Interface GE0/0/0 : 10.0.12.2/24 (Connected to R1)
* Interface GE0/0/1 : 192.168.1.2/24 (Gateway for PC2)
Options:

• A. R1 cannot ping 192.168.1.12.
• B. R2 cannot ping 10.0.12.1.
• C. R1 cannot ping 192.168.1.2.
• D. PC1 and PC2 cannot ping each other.
