NEW QUESTION # 142
A systems administrator needs to restore a backup to the /usr/app/data directory. Which of the following commands should the administrator use for this task?
Answer: C
Explanation:
The tar (tape archive) utility is the standard tool for archiving and compressing files in Linux.
According to CompTIA Linux+ V8 objectives, administrators must be proficient in extracting data into specific target locations. The command tar -xvzf /tmp/backup.tar.gz -C /usr/app/data is the correct syntax for this operation.
The flags used in the command provide the following functionality:
-x: Instructs tar to extract the contents of the archive.
-v: Enables verbose output, showing the files as they are being extracted.
-z: Tells tar to filter the archive through gzip for decompression (required for .tar.gz files).
-f: Specifies the filename of the archive to be processed (/tmp/backup.tar.gz).
-C: Changes the directory to the specified path (/usr/app/data) before performing the extraction.
Using the -C flag is the most efficient and recommended way to restore a backup to a directory other than the current working directory. Without this flag, tar would extract the files into the current directory, which might not be the intended destination and could clutter the filesystem.
NEW QUESTION # 143
A systems administrator is creating a backup copy of the /home/directory.
Which of the following commands allows the administrator to archive and compress the directory at the same time?
Answer: C
NEW QUESTION # 144
A user reports recurrent issues with an application, which is currently operational. The systems administrator gathers the following outputs to diagnose the issue:
Which of the following is a possible cause of this issue?
Answer: C
Explanation:
The logs show repeated out-of-memory kills involving the mariadb process, and the memory statistics show sustained high memory usage with no swap configured. Since the application is currently running but repeatedly grows until the kernel kills it, the likely cause is a memory leak in the process.
NEW QUESTION # 145
Due to application compatibility issues, the Python 3 OpenSSL library should not be upgraded.
Which of the following commands should the systems administrator use to ensure the package stays at the current version?
Answer: A
Explanation:
This command places the specified package on hold, preventing it from being upgraded during system updates while allowing other packages to be updated normally.
NEW QUESTION # 146
A Linux administrator needs to change the server name to comptia1. Which of the following commands should the administrator use?
Answer: C
Explanation:
The standard tool for managing the system hostname on modern Linux distributions using systemd is hostnamectl. According to the CompTIA Linux+ V8 objectives, the command hostnamectl set-hostname < name > is the correct and permanent way to change the server ' s identity.
When an administrator runs hostnamectl set-hostname comptia1, the utility updates the various types of hostnames recognized by the system:
* Static Hostname: This is stored in /etc/hostname and persists across reboots.
* Transient Hostname: A temporary name received via network configuration (like DHCP).
* Pretty Hostname: A high-level, human-readable name that can include special characters.
Using hostnamectl is preferred over manually editing /etc/hostname because it immediately notifies the kernel and running services of the change, often without requiring a reboot to take effect system-wide.
The other options are incorrect. Option A, export HOSTNAME=comptia1, only changes the environment variable for the current shell session; it does not change the system ' s actual hostname and is lost when the session ends. Option B, adding the name to /etc/resolv.conf, is incorrect because that file is used for DNS resolver settings (nameservers and search domains), not for the local system ' s hostname. Option D, systemctl daemon-reload, is used to refresh systemd after configuration changes to unit files and has no functionality for changing a hostname.
Therefore, hostnamectl is the verified command for this task.
