A systems administrator manages multiple Linux servers and needs to set up a reliable and secure way to handle the complexity of managing event records on the OS and application levels. Which of the following should the administrator do?
Answer(s): B

A Linux systems administrator is running an important maintenance task that consumes a large amount of CPU, causing other applications to slow. Which of the following actions should the administrator take to help alleviate the issue?

A systems administrator attempts to edit a file as root, but receives the following error:Which of the following commands allows the administrator to edit the file?
The lsattr output shows the immutable (i) attribute set on /etc/resolv.conf. This prevents any modifications, even by root. Running chattr -i removes the immutable flag, allowing the administrator to edit the file.
A systems administrator is having issues with a third-party API endpoint. The administrator receives the following output:Which of the following actions should the administrator take to resolve the issue?
The dig comptia.com output shows NXDOMAIN and that the query is being sent to 10.255.255.254, which is not a valid DNS server. This indicates a misconfigured DNS client configuration (e.g., /etc/resolv.conf). Fixing the DNS settings will allow proper hostname resolution.
Which of the following commands should an administrator use to see a full hardware inventory of a Linux system?
Answer(s): A
dmidecode retrieves detailed hardware information from the system's DMI/SMBIOS, including BIOS, CPU, memory, and motherboard details, providing a full hardware inventory.
A Linux administrator needs to analyze a compromised disk for traces of malware. To complete the analysis, the administrator wants to make an exact, block-level copy of the disk. Which of the following commands accomplishes this task?
Answer(s): D
The dd command performs a low-level, block-by-block copy of a device. Using if=/dev/sdc (input file) and of=/ tmp/image (output file) with a block size (bs) ensures an exact replica of the disk, suitable for forensic analysis.
