Which command history feature allows users to view a list of commands entered in a previous session?

BOOT Environment Variable

The command boot system is used to set the BOOT environment variable that defines where to find the IOS image file on a switch.
The BOOT environment variable is used by a switch to locate and load the IOS image.

Security Protocol

SSH (Secure Shell) is a protocol that adds security to remote connections.

IPv4 Loopback Interface

A characteristic of an IPv4 loopback interface on a Cisco IOS router is that it is a logical interface internal to the router.
It is not assigned to a physical port and cannot be connected to other devices.

Ethernet Frame Size

The minimum Ethernet frame size that will not be discarded by the receiver as a runt frame is 64 bytes.

Command History Feature

The command history feature allows you to view a list of commands entered in a previous session.
It also allows you to recall up to 15 command lines by default.

Boot Sequence

The first action in the boot sequence when a switch is powered on is to load the power-on self-test (POST) program.

Resetting a Lost Password

To reset a lost password on a router, an administrator must have physical access to the router.

SSH Access

When configuring a switch for SSH access, the command login local must be entered on the switch.
The command username secret is also required to be entered on the switch.

Auto-MDIX Setting

The command show interfaces displays information about the auto-MDIX setting for a specific interface.

Ethernet Connection

If one end of an Ethernet connection is configured for full duplex and the other end of the connection is configured for half duplex, late collisions will be observed on the half-duplex end of the connection.

Test your knowledge on command history feature tasks and the boot sequence of a switch. Questions cover tasks like viewing past commands, setting buffer size, and boot sequence actions like loading default software and performing CPU initialization.
