CompTIA Linux+ Certification Exam Sample Questions (Q889-Q894):

NEW QUESTION # 889
A systems administrator is creating new user accounts on several Linux machines and wants to automate the process from a Linux system used for operations. In this operations system, the list of servers is located in the /home/user/serverslist file and the list of user accounts is located in the /home/user/userslist file. Which of the following scripts will help accomplish this task?

A. bash
for server in $(cat /home/user/serverslist)
do
scp /home/user/userslist user@$server:/tmp
ssh -i user@$server "for user in $(cat /tmp/userslist)
do
sudo useradd $user
done; exit"
done
B. bash ssh user@$(cat /home/user/serverslist) "sudo useradd $(cat /home/user/userslist); exit"
C. bash
for server in $(cat /home/user/serverslist)
do
for user in $(cat /home/user/userslist)
do
sudo useradd $user
done
done
D. bash
for server in $(cat /home/user/serverslist)
do
ssh -i user@$server "for user in $(cat /home/user/userslist)
do
sudo useradd $user
done; exit"
done

Answer: D

Explanation:
The script in option B performs the task by SSH-ing into each server listed in serverslist and then adding each user listed in userslist. This is an effective way to remotely create user accounts without manually logging into each server. The ssh command allows the execution of the useradd commands on the remote machines.

NEW QUESTION # 890
A systems administrator is tasked with creating a cloud-based server with a public IP address.

Which of the following technologies did the systems administrator use to complete this task?

A. Ansible
B. Puppet
C. Terraform
D. Git

Answer: C

Explanation:
Explanation
The systems administrator used Terraform to create a cloud-based server with a public IP address. Terraform is a tool for building, changing, and versioning infrastructure as code. Terraform can create and manage resources on different cloud platforms, such as AWS, Azure, or Google Cloud. Terraform uses a declarative syntax to describe the desired state of the infrastructure and applies the changes accordingly. Terraform can also assign a public IP address to a cloud server by using the appropriate resource attributes. This is the correct technology that the systems administrator used to complete the task. The other options are incorrect because they are either not designed for creating cloud servers (Puppet or Git) or not capable of assigning public IP addresses (Ansible).

Managing Cloud and Virtualization Technologies, page 559.

NEW QUESTION # 891
Which of the following is the main purpose of SSO?

A. To allow a user to authenticate once and have access to multiple applications or systems without having to log in again
B. To serve as an information protection mechanism that protects identities with administrative access
C. To add an extra layer of protection, reducing the risk of unauthorized access, requiring more than just a password to access
D. To be an essential component for managing authentication, authorization, and identity information

Answer: A

Explanation:
SSO (Single Sign-On) allows users to authenticate once and gain access to multiple systems or services without re-authenticating. This improves user experience and reduces the number of credentials users must manage.

NEW QUESTION # 892
A Linux administrator needs to analyze a failing application that is running inside a container.
Which of the following commands allows the Linux administrator to enter the running container and analyze the logs that are stored inside?

A. podman run -d app /bin/bash
B. docker exec -d app /bin/bash
C. podman exec -ti app /bin/sh
D. docker run -ti app /bin/sh

Answer: C

Explanation:
Podman exec -ti app /bin/sh allows the Linux administrator to enter the running container and analyze the logs that are stored inside. This command uses the podman tool, which is a daemonless container engine that can run and manage containers on Linux systems. The exec option executes a command inside an existing container, in this case app, which is the name of the container that runs the failing application. The -ti option allocates a pseudo-TTY and keeps STDIN open, allowing for interactive shell access to the container. The /bin/sh argument specifies the shell command to run inside the container, which can be used to view and manipulate the log files. The other options are not correct commands for entering a running container and analyzing the logs. Docker run -ti app /bin/sh creates a new container from the app image and runs the
/bin/sh command inside it, but does not enter the existing container that runs the failing application. Podman run -d app /bin/bash also creates a new container from the app image and runs the /bin/bash command inside it, but does so in detached mode, meaning that it runs in the background without interactive shell access. Docker exec -d app /bin/bash executes the /bin/bash command inside the existing app container, but also does so in detached mode, without interactive shell access.

NEW QUESTION # 893
A Linux user reported the following error after trying to connect to the system remotely:
ssh: connect to host 10.0.1.10 port 22: Resource temporarily unavailable The Linux systems administrator executed the following commands in the Linux system while trying to diagnose this issue:
Which of the following commands will resolve this issue?

A. firewall-cmd --zone=public --permanent --add-port=22/udp
B. firewall-cmd --zone=public --permanent --add-service=22
C. firewall-cmd --zone=public --permanent --add-service=ssh
D. systemct1 enable firewalld; systemct1 restart firewalld

Answer: C

Explanation:
The firewall-cmd --zone=public --permanent --add-service=ssh command will resolve the issue by allowing SSH connections on port 22 in the public zone of the firewalld service. This command will add the ssh service to the permanent configuration of the public zone, which means it will persist after a reboot or a reload of the firewalld service. The firewall-cmd --zone=public --permanent --add-service=22 command is invalid, as 22 is not a valid service name. The systemct1 enable firewalld; systemct1 restart firewalld command will enable and restart the firewalld service, but it will not change the firewall rules. The firewall-cmd --zone=public -- permanent --add-port=22/udp command will allow UDP traffic on port 22 in the public zone, but SSH uses TCP, not UDP.
