To retrieve the scripts from a repository and make them available on a local workstation, the junior Linux administrator can use the command git clone ©. This will create a copy of the repository on the local machine, including all the scripts and history. The other commands will not clone the repository, but either fetch, checkout, or branch from an existing repository. References:

The correct command to list all local accounts in which the UID is greater than 500 is:

awk -F: '$3 > 500 {print $1}' /etc/passwd

This command uses awk to process the /etc/passwd file, which contains information about the local users on the system. The -F: option specifies that the fields are separated by colons. The $3 refers to the third field, which is the UID. The condition $3 > 500 filters out the users whose UID is greater than 500. The action {print $1} prints the first field, which is the username.

The other commands are incorrect because:

find /etc/passwd —size +500 will search for files that are larger than 500 blocks in size, not users with UID greater than 500.

cut —d: fl / etc/ passwd > 500 will cut the first field of the /etc/passwd file using colon as the delimiter, but it will not filter by UID or print only the usernames. The > 500 part will redirect the output to a file named 500, not compare with the UID.

sed '/UID/' /etc/passwd < 500 will use sed to edit the /etc/passwd file and replace any line that contains UID with 500, not list the users with UID greater than 500. The < 500 part will redirect the input from a file named 500, not compare with the UID.

The Internal Certificate Authority (ICA) is created during the primary Security Management Server installation process. The ICA is a component of Check Point’s Public Key Infrastructure (PKI) that issues and manages certificates for Security Gateways and administrators. The ICA is automatically installed and initialized when the primary Security Management Server is installed. The ICA is not created upon creation of a certificate, when an administrator decides to create one, or when an administrator initially logs into SmartConsole. References: Check Point Certified Security Administrator (CCSA) R80.x Study Guide, Chapter 3: Check Point Security Management Architecture, page 32.

To run a script file, the user needs to have execute permission on the file. The command chmod u+x /home/user/script.sh (A) will grant execute permission to the owner of the file, which is the user who created it. The other commands will not give execute permission to the user, and therefore will not allow the script to run properly. References:
