An administrator is implementing a backup strategy for a Samba server that uses the 'tdbsam' passdb backend. The goal is to ensure that user accounts and passwords can be restored without restoring the entire operating system. Which file or directory is essential to include in the backup for this purpose?

/var/lib/samba/private/passdb.tdb

An organization is planning a disaster recovery test for its Samba file server. The administrator needs to ensure that the Samba configuration and the user database can be fully restored on a new server. The current server uses the tdbsam passdb backend. Which backup strategy will provide a complete and consistent restore of both the configuration and the user accounts?

Use 'pdbedit -L' to list all users and save the output to a text file for later re-creation.

Run 'net backup' while the server is under load to capture a point-in-time snapshot of the TDB files.

Back up only the /etc/samba/smb.conf file, as the user database is automatically recreated from the domain controller.

Copy /etc/samba/smb.conf and the /var/lib/samba/private/passdb.tdb file while the smbd service is stopped.

A Samba server is running an older version that has a known security vulnerability. The administrator needs to apply the security update but must minimize downtime for users who are actively using the file shares. What is the safest and most appropriate procedure to follow?

Schedule a maintenance window, stop the smbd service, apply the update, and restart the service.

Copy the new binaries over the old ones and rely on the kernel to load the new version on the next connection.

Apply the update while the service is running, as Samba supports hot-patching of its binaries.

Use the 'smbcontrol smbd reload' command to load the new binaries without interrupting current sessions.

An administrator is about to perform a minor version upgrade of Samba (e.g., from 4.17.5 to 4.17.7). The server is in production and has many active users. The administrator has a recent backup of the configuration and user database. What is the most appropriate approach to minimize risk during this upgrade?

Use 'smbcontrol smbd reload' to load the new binaries without interrupting sessions.

Skip the upgrade if the release notes do not mention any security fixes.

Apply the upgrade while the service is running, as minor version upgrades are designed to be hot-swappable.

Perform the upgrade during a maintenance window, stopping the smbd service, and restarting it after the upgrade is complete.
