CompTIA Linux+ Certification Exam Sample Questions (Q372-Q377):

NEW QUESTION # 372
A junior administrator is setting up a new Linux server that is intended to be used as a router at a remote site.
Which of the following parameters will accomplish this goal?

Answer: D

Explanation:
Explanation
The parameter net.ipv4.ip_forward=1 will accomplish the goal of setting up a new Linux server as a router.
This parameter enables the IP forwarding feature, which allows the server to forward packets between different network interfaces. This is necessary for a router to route traffic between different networks. The parameter can be set in the /etc/sysctl.conf file or by using the sysctl command. This is the correct parameter to use to accomplish the goal. The other options are incorrect because they either do not exist (net.ipv4.ip_forwarding or net.ipv4.ip_route) or do not enable IP forwarding (net.ipv4.ip_forward=0).

Managing Network Connections, page 382.

NEW QUESTION # 373
A systems administrator installed a new software program on a Linux server. When the systems administrator tries to run the program, the following message appears on the screen.

Which of the following commands will allow the systems administrator to check whether the system supports virtualization?

A. dmidecode -s system-version
B. lscpu
C. sysctl -a
D. cat /sys/device/system/cpu/possible

Answer: B

Explanation:
The command that will allow the systems administrator to check whether the system supports virtualization is lscpu. This command will display information about the CPU architecture, such as the number of CPUs, cores, sockets, threads, model name, frequency, cache size, and flags. One of the flags is vmx (for Intel processors) or svm (for AMD processors), which indicates that the CPU supports hardware virtualization. If the flag is present, it means that the system supports virtualization. If the flag is absent, it means that the system does not support virtualization or that it is disabled in the BIOS settings.
The other options are not correct commands for checking whether the system supports virtualization. The dmidecode -s system-version command will display the version of the system, such as the product name or serial number, but not the CPU information. The sysctl -a command will display all the kernel parameters, but not the CPU flags. The cat /sys/devices/system/cpu/possible command will display the range of possible CPUs that can be online or offline, but not the CPU features.

NEW QUESTION # 374
Which of the following settings for umask ensures that new files have the default permissions -rw- r----- ?

A. 0027
B. 0640
C. 0017
D. 0038

Answer: A

Explanation:
The permissions we want are 750 for directories and 640 for files.
To calculate the umask value simply subtract the desired permissions from the default one:
Umask value: 777-750 = 027

NEW QUESTION # 375
Users report that connections to a MariaDB service are being closed unexpectedly. A systems administrator troubleshoots the issue and finds the following message in /var/log/messages:

Which of the following is causing the connection issue?

A. The process mysqld is using too many semaphores.
B. The server is running out of file descriptors.
C. Something is starving the server resources.
D. The amount of RAM allocated to the server is too high.

Answer: B

Explanation:
The message in /var/log/messages indicates that the server is running out of file descriptors. A file descriptor is a non-negative integer identifier for an open file in Linux. Each process has a table of open file descriptors where a new entry is appended upon opening a new file. There is a limit on how many file descriptors a process can open at a time, which depends on the system configuration and the user privileges. If a process tries to open more files than the limit, it will fail with an error message like "Too many open files". This could cause connections to be closed unexpectedly or other problems with the application.
The other options are not correct causes for the connection issue. The process mysqld is not using too many semaphores, which are synchronization mechanisms for processes that share resources. Semaphores are not related to file descriptors or open files. Something is not starving the server resources, which could mean high CPU usage, memory pressure, disk I/O, network congestion, or other factors that affect performance. These could cause slowdowns or timeouts, but not file descriptor exhaustion. The amount of RAM allocated to the server is not too high, which could cause swapping or paging if it exceeds the physical memory available.
This could also affect performance, but not file descriptor availability. References: File Descriptor Requirements (Linux Systems); Limits on the Number of Linux File Descriptors
