In the HCIA–Cloud Computing syllabus, Linux command-line operations are part of theOperating System Basicsdomain. Viewing file contents is one of the most common Linux administration tasks.

Theless (A)command is used to view file contents page by page. It supports forward and backward scrolling and searching, making it suitable for viewing large files. HCIA materials often recommend less as a preferred file-viewing tool.

Themore (B)command is an earlier paging command that displays file contents one screen at a time. Although it has fewer features than less, it is still a valid file-viewing command.

Thecat (D)command is used to display the entire content of a file directly to standard output. It is commonly used for viewing small files or concatenating files.

Thevim (C)command is primarily atext editor, not a file-viewing command. While it can open and display files, its main purpose is editing rather than viewing, which is how HCIA differentiates it.

Therefore, the correct answers areA, B, and D.

In HCIA–Cloud Computing (Operating System Basics), Linux network interface configuration is a foundational skill, and openEuler follows the standard Red Hat–style network configuration syntax.

To configure a static IP address, the parameter BOOTPROTO must be set to static. This tells the operating system not to request an IP address from a DHCP server and instead use the manually configured values such as IPADDR and NETMASK.

To ensure that the NIC is automatically activated when the system boots, the parameter ONBOOT must be set to yes. If ONBOOT is set to no, the interface will remain down after boot and must be manually started.

Therefore, the completed and correct configuration is:

BOOTPROTO=static

ONBOOT=yes

BOOTPROTO=static → Uses a fixed IP address

ONBOOT=yes → Enables automatic startup at system boot

This configuration exactly matches HCIA–Cloud Computing requirements for static IP configuration on openEuler.
