CompTIA XK0-005 Exam With Confidence Using Practice Dumps

The httpd.service is the Apache HTTPD Server, which is a web service that runs on Linux systems. The output 1 shows that the httpd.service is inactive (dead), which means that it is not running. The output 1 also shows that the httpd.service is disabled, which means that it is not enabled to auto start at boot time. Therefore, the statements C and D best describe the root cause of the issue. The statements A, B, E, and F are incorrect because they do not match the output 1. References: [How to Manage Systemd Services on a Linux System]

Comprehensive and Detailed Explanation From Exact Extract:

The correct way to temporarily allow specific services in a particular zone with firewalld is to use firewall-cmd --add-service=service --zone=zone. Multiple services can be specified in curly braces and separated by commas. The correct syntax is:

bash

CopyEdit

firewall-cmd --add-service={dns,http,https} --zone=internal

This command will allow DNS (port 53), HTTP (port 80), and HTTPS (port 443) through the firewall for the "internal" zone temporarily (for the current runtime session).

Other options:

A. The command syntax is incorrect; firewalld is a service, not a command-line tool.

B. iptables does not use the --enable-service flag, nor does it have zones in this way.

D. systemctl mask disables services, and the rest of the command is invalid.

A is correct syntax to bring up a network interface.

Incorrect Options:

B, C, D: Invalid or misused ip link subcommands.
