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.
