H13-511_V5.5 Exam Dumps - HCIA-Cloud Computing V5.5 Exam

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.

The HCIA–Cloud Computing syllabus explains that routers are responsible forinter-network communicationand packet forwarding based onIP addresses. In the TCP/IP reference model, this function corresponds to theNetwork layer.

Routers analyze the destination IP address of a packet and use routing tables and routing protocols to determine thebest pathfor forwarding the packet to its destination. This behavior is distinct from switches, which forward frames based on MAC addresses at the data link layer.

TheData link layer (A)is associated with switches, theTransport layer (D)handles end-to-end communication (such as TCP and UDP), and theApplication layer (C)provides services to applications.

Therefore, according to HCIA–Cloud Computing network fundamentals, the correct answer isNetwork layer.
