CompTIA Linux+ Certification Exam Sample Questions (Q880-Q885):

NEW QUESTION # 880
A systems administrator is deploying three identical, cloud-based servers. The administrator is using the following code to complete the task:

Which of the following technologies is the administrator using?

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

Answer: B

Explanation:
Explanation
The code snippet is written in Terraform language, which is a tool for building, changing, and versioning infrastructure as code. Terraform uses a declarative syntax to describe the desired state of the infrastructure and applies the changes accordingly. The code defines a resource of type aws_instance, which creates an AWS EC2 instance, and sets the attributes such as the AMI ID, instance type, security group IDs, and key name. The code also uses a count parameter to create three identical instances and assigns them different names using the count.index variable. This is the correct technology that the administrator is using. The other options are incorrect because they use different languages and syntaxes for infrastructure as code.

NEW QUESTION # 882
A Linux administrator is troubleshooting SSH connection issues from one of the workstations.
When users attempt to log in from the workstation to a server with the IP address 104.21.75.76, they receive the following message:

The administrator reviews the information below:

Which of the following is causing the connectivity issue?

A. The sshd service is disabled.
B. The workstation has the wrong IP settings.
C. The server's firewall is preventing connections from being made.
D. The server has an incorrect default gateway configuration.

Answer: C

Explanation:
The server's firewall is preventing connections from being made, which is causing the connectivity issue. The output of iptables -L -n shows that the firewall is blocking all incoming traffic on port 22, which is the default port for SSH. The output of ssh -v user@104.21.75.76 shows that the connection is refused by the server. To resolve the issue, the administrator needs to allow port 22 on the firewall. The other options are incorrect because they are not supported by the outputs. The workstation has the correct IP settings, as shown by the output of ip addr show. The sshd service is enabled and running, as shown by the output of systemct1 status sshd. The server has the correct default gateway configuration, as shown by the output of ip route show. Reference: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 13: Managing Network Services, pages 406-407.

A. ls -al test/
B. getfacl test/
C. getsebool test/
D. getenforce test/

Answer: B

Explanation:
getfacl is the command used to view the Access Control List (ACL) of a file or directory, which shows extended permissions beyond the basic owner, group, and others. This is essential for checking permissions that are set using ACLs on the directory test.

A. fdisk -V
B. lsscsi -s
C. lsusb -t
D. partprobe -a

Answer: B

The lsscsi command can list the SCSI devices on the system, along with their size and device name. The -s option shows the size of each device. The administrator can look for the device that has a size of 500G and note its device name.
