NEW QUESTION # 41
As root you configured a file system using AutoFS with default settings. In the first session, you changed to a directory under AutoFS control. In a second session, you changed to /etc. Now the idle time for the session expires. Which two statements are true about the status of the file system mounted in the first session?

A. It remains mounted until you log out from the first session.
B. It was unmounted from the first session when the timer expired.
C. It was unmounted when the second session began.
D. It remains mounted until you switch to a directory outside the current mount point.
E. It remains mounted as long as the system is running.

Answer: A,D

Explanation:
Understanding AutoFS Behavior:
* AutoFSautomatically mounts file systems when accessed and unmounts them after a period of inactivity (default is 5 minutes).
* A file system remains mounted as long as it isactive, meaning processes are accessing files or directories within it.
Scenario Analysis:
* First Session:
* Changed to a directory under AutoFS control (mount point is active).
* Second Session:
* Changed to /etc (does not affect the first session).
* Idle Time Expires:
* AutoFS checks for idle mounts to unmount.
Implications:
* The mount point remainsactivebecause the shell in the first session is in the AutoFS directory.
* AutoFS willnotunmount the file system while it is active.
Oracle Linux Reference:
* OracleLinux 8: Configuring File Systems-Using the Automounter:
"A file system remains mounted as long as there are open files or directories within it." Correct Options:
* Option B:The file system remains mounted until you log out from the first session.
* Option E:The file system remains mounted until you switch to a directory outside the current mount point.
Why Other Options Are Incorrect:
* Option A:Incorrect because the mount does not persist indefinitely; it's unmounted when no longer active.
* Option C:Incorrect because the mount is still active; the timer does not cause unmounting in this case.
* Option D:Incorrect because the second session does not influence the mount status in the first session.

NEW QUESTION # 42
Which two directories store PAM authentication modules?

A. /var/lib
B. /usr/lib
C. /lib64/security
D. /lib/security
E. /etc/pam.d

Answer: C,D

Explanation:
* Option A (Correct):/lib64/securityis a common directory where PAM (Pluggable Authentication Module) libraries are stored for 64-bit systems.
* Option D (Correct):/lib/securityis another directory where PAM libraries are stored, usually on 32-bit systems or as a fallback for 64-bit systems.
* Option B (Incorrect):/etc/pam.dcontains configuration files for PAM modules but does not store the modules themselves.
* Option C (Incorrect):/usr/libis a general directory for libraries but does not specifically store PAM modules.
* Option E (Incorrect):/var/libis typically used for variable state information and is not relevant for storing PAM modules.
Oracle Linux Reference:Refer to:
* OracleLinux 8: Managing Authentication

NEW QUESTION # 43
Examine these requirements for a host with a user oracle:
* Network services must run in a confined domain.
* The oracle user must be confined.
* The oracle user must be able to use Mozilla Firefox.
* Access to files and directories must be granted based only on SELinux contexts.
* The SELinux configuration must be persistent across system restarts.
* Users must be able to publish private HTML content.
Now examine these commands and output:
# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: permissive
Policy MLS status: enabled
Policy deny_unknown status: allowed
Memory protection checking: actual (secure)
Max Kernel policy version: 31
# setenforce enforcing
# semanage login -a -s guest_u oracle
# setsebool -P http_enable_homedirs on
Which requirements are satisfied?

A. 1, 2, 6
B. 1, 2, 3, 4, 5, 6
C. 1, 2, 3, 6
D. 1, 2, 4, 6
E. 1, 2, 3, 5, 6
F. 1, 2, 4, 5, 6

Answer: F

Explanation:
Explanation of Answer A:
* Network services running in a confined domain: SELinux provides domain confinement for services, ensuring they run with restricted access based on their defined policies.
* The oracle user must be confined: The commandsemanage login -a -s guest_u oracleconfines theoracleuser to theguest_uSELinux user role, which is a confined role.
* Access to files and directories based only on SELinux contexts: With SELinux enabled and the policy loaded, access is governed by SELinux contexts.
* Persistent SELinux configuration across reboots: Thesetenforce enforcingcommand, combined with the appropriate policy configuration, ensures that SELinux remains in enforcing mode across reboots.
* Users able to publish private HTML content: Thesetsebool -P http_enable_homedirs oncommand enables the use of user home directories for web content, allowing users to host personal web pages.
