Question 1

[Cisco IOS Software Basics]

Which common CLI command is used to install Cisco NX-OS Software?

Acopy tftp: running-config

Binstall all

Cinstall kickstart

Dboot system

Correct : B

The install all command is the standard method used to install or upgrade Cisco NX-OS software on Nexus switches. This command streamlines the installation process by automating tasks such as verifying the software image, checking for compatibility, and managing the installation of optional packages or SMUs (Software Maintenance Upgrades). It ensures a comprehensive and efficient upgrade process, minimizing the potential for errors.Cisco

In contrast:

copy tftp: running-config is used to copy configuration files, not software images.

install kickstart is an outdated command from earlier NX-OS versions.

boot system sets the boot variable but does not handle the full installation process.

Question 2

[Cisco Equipment and Related Hardware]

What is the primary role of a switch in a local area network?

Ato route data packets between different networks

Bto encrypt data transmissions for security

Cto divide the network into separate collision domains

Dto provide wireless connectivity to LAN devices

Correct : C

In a local area network (LAN), the primary function of a switch is to operate at Layer 2 (Data Link Layer) of the OSI model. Switches use MAC addresses to forward frames to the appropriate destination ports. This targeted forwarding mechanism divides the network into separate collision domains for each switch port. By isolating collision domains, switches significantly reduce the chance of collisions, enhancing the performance and efficiency of the network.

Unlike hubs, which forward all traffic to all ports (thus creating a single collision domain), switches intelligently forward only the necessary traffic to the correct port. This capability allows multiple simultaneous conversations on different switch ports without interference.

Routers, which operate at Layer 3 (Network Layer), are used to route packets between different networks, not within the same LAN. Wireless connectivity is provided by wireless access points (WAPs), not switches. Encryption is typically handled by security protocols or devices such as firewalls and not by switches directly.
