CompTIA Linux+ Certification Exam XK0-006 Pr¨¹fungsfragen mit Lösungen (Q150-Q155):150. Frage
A Linux administrator observes a low network throughput on a Linux system. The Linux administrator gathers the following output:

Which of the following is the cause of a low network throughput?
Antwort: C
Begr¨¹ndung:
The interface is configured with a jumbo MTU, and the ping test with the do-not-fragment flag shows fragmentation errors, indicating that packets larger than the path MTU cannot be transmitted. This MTU mismatch causes fragmentation or dropped packets, resulting in reduced network throughput.

151. Frage
Which of the following commands should an administrator use to see a full hardware inventory of a Linux system?
Antwort: A
Begr¨¹ndung:
Hardware inventory and system information gathering are core responsibilities in Linux system management and are explicitly covered in CompTIA Linux+ V8 objectives. Among the listed commands, dmidecode is the most comprehensive tool for retrieving detailed hardware inventory information.
The dmidecode command reads data directly from the system's DMI (Desktop Management Interface) / SMBIOS tables, which are provided by the system firmware (BIOS or UEFI). It reports detailed information about system hardware components, including motherboard details, BIOS version, system manufacturer, CPU sockets, memory slots, installed RAM modules, serial numbers, and asset tags. This makes it the preferred tool when a full hardware inventory is required.
The other options provide only partial or specific information. lsmod lists currently loaded kernel modules and does not provide physical hardware inventory. dmesg displays kernel ring buffer messages, which may include hardware detection logs but are not structured or complete inventory data. lscpu reports CPU architecture and processor details only, not the entire system hardware.
Linux+ V8 documentation highlights dmidecode as the authoritative utility for system hardware discovery and inventory auditing. It is commonly used in enterprise environments for documentation, troubleshooting, capacity planning, and compliance reporting.
Because it provides the most complete and authoritative hardware information available from the system firmware, the correct answer is A. dmidecode.

152. Frage
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?
Antwort: A
Begr¨¹ndung:
A centralized log aggregation solution (such as Elasticsearch, Graylog, or Splunk) provides reliable and secure management of logs across multiple servers. It consolidates OS and application logs, simplifies analysis, and improves monitoring and security compared to on- demand retrieval, backups, or simple log rotation.

153. Frage
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?
Antwort: C
Begr¨¹ndung:
This command places the specified package on hold, preventing it from being upgraded during system updates while allowing other packages to be updated normally.

154. Frage
Which of the following is a reason multiple password changes on the same day are not allowed?
Antwort: A
Begr¨¹ndung:
Password policy enforcement is a critical component of system security covered in the CompTIA Linux+ V8 objectives. One common control implemented in Linux systems is restricting how frequently users can change their passwords, often referred to as minimum password age enforcement.
The primary reason multiple password changes within a short time frame are not allowed is to prevent password cycling attacks. Without this restriction, a user could repeatedly change their password in quick succession to bypass password history controls and eventually reuse a previously compromised or weak password. Option C accurately describes this scenario and aligns directly with Linux+ V8 security guidance.
Linux systems enforce this behavior through tools such as chage and PAM (Pluggable Authentication Modules). Administrators can configure minimum password age values to ensure users must wait a defined period before changing passwords again. This ensures that password history requirements are effective and meaningful.
The other options are incorrect. Option A confuses password expiration with brute-force mitigation, which is typically addressed through account lockout policies. Option B refers to password complexity, which is enforced through character requirements rather than change frequency. Option D is unrelated, as password expiration policies do not enforce multifactor authentication.
Linux+ V8 documentation emphasizes layered access controls, and preventing password reuse through enforced timing restrictions is a core principle of secure authentication design.
Therefore, the correct answer is C.
