Oracle Linux 8 Advanced System Administration Sample Questions (Q21-Q26):

NEW QUESTION # 21
Which is true about the /etc/sysconfig directory in an Oracle Linux 8 system?

A. Files in this directory hierarchy contain information about running processes.
B. Files in this directory hierarchy contain information about system hardware.
C. Its contents depend on the packages installed on the system.
D. It is used to access device and device driver information.

Answer: C

NEW QUESTION # 22
Examine this command:
# auditctl -w /etc/passwd -p w -k pass
Which two statements are true upon execution?

A. An audit is defined that creates a log entry every time a write occurs to /etc/passwd.
B. An audit rule is defined with the keyword pass.
C. An audit rule is defined that creates a log entry every time /etc/passwd is read.
D. A write occurs to /etc/audit/audit.rules.
E. A write occurs to /etc/audit/rules.d/audit.rules.

Answer: A,B

NEW QUESTION # 23
Which two directories store PAM authentication modules?

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

Answer: A,E

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 # 24
Which two statements are true about container technology?

A. Containers package an application with the individual runtime stack.
B. Podman requires a running daemon to function and to enable containers to start and run without root permissions.
C. A container application is dependent on the host operating system and kernel version.
D. A container application built on a bare metal system cannot run on virtual machines or cloud instances.
E. Podman, Buildah, and Skopeo are independent tools to create, run, and manage container applications across compatible Oracle Linux systems.

Answer: C,E

Explanation:
* Option B (Correct):Container applications are dependent on the host operating system's kernel because containers share the OS kernel, unlike virtual machines, which use a hypervisor. Compatibility of the host OS kernel version is required to run containers.
* Option D (Correct):Podman, Buildah, and Skopeo are container tools for managing container applications. Podman runs containers without requiring a daemon like Docker, Buildah is used to build container images, and Skopeo is used for transferring container images. These tools can operate independently of one another, providing a flexible and modular approach to container management on Oracle Linux.
* Option A (Incorrect):Container applications built on bare metal can run on virtual machines or cloud instances as long as the environment supports the container runtime.
* Option C (Incorrect):Containers do not package the entire runtime stack; they include the application and its dependencies but rely on the host OS for the kernel.
* Option E (Incorrect):Podman does not require a running daemon; one of its advantages over Docker is that it can run containers in rootless mode without needing a persistent daemon.
Oracle Linux Reference:Refer to:
* OracleLinux 8: Podman and Containers Guide
* man podman,man buildah,man skopeofor further details on these tools.

NEW QUESTION # 25
Which two statements are true about the configuration and use of cron or anacron?

A. cron jobs may run only once a minute.
B. All crontabs are held in the /etc/cron.d directory.
C. anacron jobs may run only once a day.
D. anacron jobs are used to run cron jobs if the system was powered off when they were scheduled to run.
E. The crond daemon looks for jobs only in /etc/crontab.

Answer: C,D

Explanation:
Option D: anacron jobs may run only once a day.
* Explanation:
* Anacronis designed for systems that are not running continuously (e.g., desktops or laptops that may be powered off at night). It ensures that scheduled tasks are executed at the specified intervals.
* Anacron jobs are defined with periods indays. The minimal unit of time for scheduling in Anacron isone day. Therefore, Anacron can schedule jobs to runonce a dayat most.
* It is not intended for tasks that need to run multiple times per day.
* Oracle Linux Reference:
* OracleLinux 8: Scheduling Tasks- Section onAnacron Configuration Files:
"Anacron is used to run commands periodically with a frequency specified in days." Option E: anacron jobs are used to run cron jobs if the system was powered off when they were scheduled to run.
* Explanation:
* Anacron complements Cron by ensuring thatscheduled jobs are not missedif the system is powered off or in standby mode at the time they were supposed to run.
* When the system boots up, Anacron checks for any scheduled jobs that did not run and executes them accordingly.
* This is particularly useful for laptops or desktops that are not always on.
* Oracle Linux Reference:
* OracleLinux 8: Scheduling Tasks- Section onUnderstanding Anacron:
"Anacron is designed to run commands periodically with specified frequency, but unlike cron, it does not assume that the system is running continuously." Why Other Options Are Not Correct:
* Option A:cron jobs may run only once a minute.
* Explanation:
* Cron allows scheduling tasks with a minimum granularity ofone minute. However, this means that tasks can be scheduled to runevery minute, not limited to only once a minute.
* Multiple cron jobs can be scheduled to run at the same minute.
* Therefore, the statement is misleading; cron jobs can runas frequently as every minute, but notonly once a minute.
* Option B:All crontabs are held in the /etc/cron.d directory.
* Explanation:
* The /etc/cron.d directory is used for system-wide cron jobs provided by packages or administrators.
* User-specific cron jobs are stored in /var/spool/cron/ or managed via the crontab command and not placed in /etc/cron.d.
* Additionally, the system crontab file is /etc/crontab, and there are also directories like /etc
/cron.hourly, /etc/cron.daily, etc.
* Option C:The crond daemon looks for jobs only in /etc/crontab.
* Explanation:
* The crond daemon checks multiple locations for scheduled jobs:
* User crontabs managed via the crontab -e command (stored in /var/spool/cron/).
* System-wide crontab file (/etc/crontab).
* The /etc/cron.d/ directory.
* The /etc/cron.hourly/, /etc/cron.daily/, /etc/cron.weekly/, and /etc/cron.monthly/ directories.
* Therefore, crond does not look for jobsonlyin /etc/crontab.
Conclusion:
OptionsDandEare correct because they accurately describe the characteristics and purposes of Anacron in the context of scheduling tasks on an Oracle Linux system.
