Correct answer: Side-by-side Migration

Side-by-side migration involves installing the new version of the product on the same machine as the old version (or a different machine) without uninstalling the old version. This allows both environments to exist simultaneously, facilitating verification and easy rollback (switching back to the old server) if issues arise. graph LR Old[WAS v8.5.5] -->|WASPreUpgrade| Backup[Migration Backup] Backup -->|WASPostUpgrade| New[WAS v9.0.5] style Old fill:#f9f,stroke:#333,stroke-width:2px style New fill:#bbf,stroke:#333,stroke-width:2px

Correct answer: backupConfig.sh -nostop

The `backupConfig` command by default stops the node agent or server to ensure configuration integrity. Adding the `-nostop` parameter forces the backup to proceed without stopping the servers, though it carries the risk of an inconsistent backup if configuration changes are happening simultaneously.

Correct answer: ivt_client.log

The Installation Verification Tool (IVT) logs its specific activity and errors to the `ivt_client.log` file located in the profile's logs directory. While `SystemOut.log` might show server-side processing, `ivt_client.log` is the specific log for the verification tool's execution.

Correct answer: True

This is True. IBM Installation Manager modifies the core product binaries. Therefore, all java processes (Servers, Node Agents, DMGR) using those binaries must be stopped to release file locks and ensure the update is applied correctly to the installation root.

Correct answers: -machineChange; -keepDmgrEnabled

`WASPreUpgrade` uses `-machineChange` (true/false) to indicate if the migration is crossing machine boundaries, which affects how node paths are handled.

`WASPreUpgrade` uses `-keepDmgrEnabled` to determine if the old Deployment Manager should remain active/enabled during the migration process.

Correct answer: Peer-to-Peer mode

In Peer-to-Peer mode, every server in the cluster replicates its sessions to other servers in the cluster. This eliminates the single point of failure and distributes the replication workload, fulfilling the requirement. Client/Server mode would require dedicated session servers. Database persistence was ruled out by the performance requirement. graph TD subgraph Cluster S1[Server 1] S2[Server 2] S2 S3[Server 3] S3 S4[Server 4] S4 S1 end Note[Peer-to-Peer Replication Ring]
