Which two commands are valid for copying a saved configuration to RAM? (Choose two.)

In Cisco IOS, the active device configuration, known as the running-config, is stored in RAM. A saved configuration can either be the startup-config stored in NVRAM or a file on a remote server. The question asks for commands that copy a saved configuration to RAM. The command copy startup-config running-config directly copies the locally saved configuration from NVRAM into RAM, merging it with the current running configuration. The command copy tftp running-config copies a configuration file from a remote TFTP server into the running configuration in RAM. This is another valid method for loading a saved configuration onto a device.

B. copy running-config startup-config: This command saves the active configuration from RAM to NVRAM. It is the reverse of the requested action.
D. copy running-config tftp: This command backs up the active configuration from RAM to a TFTP server, rather than loading a saved configuration.
E. copy tftp startup-config: This command copies a configuration to NVRAM (startup-config), not directly to RAM (running-config). The device must be reloaded for this configuration to become active.

1. Cisco Systems, "Cisco IOS Configuration Fundamentals Command Reference". This document details the copy command and its syntax.

Reference for A: Under the copy command description, the syntax copy startup-config running-config is specified with the purpose "To merge the startup configuration with the configuration in running memory."

Reference for C: The syntax copy tftp[:[[//location]/directory]/filename] running-config is specified with the purpose "To copy a configuration file from a TFTP server to the running configuration."

2. Cisco Systems, "Cisco IOS XE Fuji 16.9.x (Catalyst 9300 Switches) - Basic Device Management Command Reference".

Section: copy command. This reference explicitly documents the usage of copy startup-config running-config to load the startup configuration into RAM and copy tftp running-config to load a configuration from a network server into RAM. It clarifies that running-config is the configuration in RAM.

3. Cisco Systems, "Managing Configuration Files Configuration Guide, Cisco IOS XE Release 3S".

Section: "Configuration File Management Overview". This guide explains that the running configuration file resides in RAM.

Section: "Copying a Configuration File from a Network Server to the Running Configuration File". This section provides the exact steps and command syntax for copy tftp running-config.
