Which of the following commands should replace the <CONDITIONAL> string?
Which of the following commands should replace the <CONDITIONAL> string?
Correct Answer: A
The correct conditional to check if a file exists and is a regular file is 'if [ -f "$filename" ]; then'. The '-f' flag checks if the supplied filename corresponds to an existing regular file. The correct syntax includes 'then' to specify the start of the block of commands to execute if the file exists. This makes option A the correct choice.

Which of the following technologies is the administrator using?
Which of the following technologies is the administrator using?
Correct Answer: D
The provided code snippet is for deploying resources using Terraform. Key indicators of this include the 'resource' keyword, the use of interpolation syntax with '${}', and the '.tf' file structure conventions. Terraform is a tool used for building, changing, and versioning infrastructure safely and efficiently. It supports various infrastructure providers, including AWS, which is evident from the use of the 'ec2_instance' within the code.

Which of the following technologies can be used as a central repository of Linux users and groups?
Correct Answer: A
LDAP (Lightweight Directory Access Protocol) can be used as a central repository of Linux users and groups. LDAP is a widely used protocol for directory services, allowing the storage and retrieval of information related to users, groups, and other resources in a network. This makes it an ideal choice for managing centralized user and group information across multiple Linux systems.

A systems administrator is troubleshooting connectivity issues and trying to find out why a Linux server is not able to reach other servers on the same subnet it is connected to. When listing link parameters, the following is presented:
Based on the output above, which of following is the MOST probable cause of the issue?
Based on the output above, which of following is the MOST probable cause of the issue?
Correct Answer: D
The most probable cause of the issue is that the network interface cable is not connected to a switch. The output shows that the state of the network interface eth0 is 'DOWN' and it also indicates 'NO-CARRIER', which means that the interface is not currently connected to a network. This typically suggests a physical disconnection, such as an unplugged cable or a problem with the switch.
