CIFS (Common Internet File System) is a protocol that allows file sharing across different operating systems, such as Unix and Windows. It supports read and write access to files and folders on a network share. It is also known as SMB (Server Message Block). Verified References: [CIFS], [File sharing]

This is the best command to find out which commands can be used by a user with sudo privileges because it lists the allowed and forbidden commands for a given user or role. The -l option stands for list, and the -U option specifies the user name. The output of this command will show what commands can be executed with sudo by that user on that server. References:

Push notifications are messages that are sent from an application or a service to a user’s device without requiring the user to open or request them. They can be used as a cost-effective technique for implementing MFA (Multi-Factor Authentication) on servers by sending verification codes or approval requests to the user’s smartphone or tablet when they try to log in to the server.

The goal is to achieve 2TB total storage, high performance, and support for one drive failure. Using RAID 5 or RAID 10 can provide redundancy while maximizing performance.

1, 2, 4, 5, and 6 (Answer C): This selection includes the highest-capacity and highest-performance drives (600GB and 500GB at high RPM speeds). Using these drives will provide the necessary capacity (500GB + 600GB + 500GB + 600GB + 600GB = 2.8TB) and performance with one drive redundancy (RAID 5 or 10).

Other options (A, B, D): These combinations either lack the necessary capacity or mix slower drives (7,200rpm), reducing overall performance.
