Which installation method for SONiC is most suitable when a switch does not have network connectivity to a provisioning server and the engineer has physical access to the device?

Package-based installation using apt-get

USB-based installation from a bootable USB drive

Cloud-based installation via a management portal

Network-based installation using DHCP and TFTP

A network engineer needs to install SONiC on a bare-metal switch that has no operating system preinstalled. The switch hardware supports the Open Network Install Environment (ONIE). Which installation method is most appropriate for this scenario?

Copy the SONiC image to the switch's flash and reboot

Use ONIE to discover and install the SONiC image from a network server

Install SONiC by running a package manager command on the switch

Use a USB drive with a SONiC image and boot from it

Which upgrade method for SONiC is most appropriate when the goal is to update only specific software components, such as a particular daemon, without changing the entire OS image?

Image-based upgrade using 'sonic-installer install'

Downgrade to a previous image using 'sonic-installer set'

Configuration reload using 'config reload'

Package-based upgrade using 'apt-get upgrade'

A switch is currently running a custom SONiC image built in-house. The team wants to move to the standard community SONiC image. The switch has no previous SONiC image installed. What is the most appropriate process to achieve this?

Copy the community image to the switch and reboot to load it from the flash.

Use the sonic-installer to upgrade from the custom image to the community image.

Downgrade the custom image to an older version first, then upgrade to the community image.

Perform a fresh installation of the community image using ONIE, which will replace the custom image.

A switch was upgraded from SONiC 202012 to 202111. After the upgrade, a critical routing feature is not working as expected. The engineer needs to revert to the previous version quickly. The switch has the previous image still available in its image list. What is the most appropriate action?

Reinstall the previous image using ONIE from a network server.

Use the sonic-installer to set the previous image as the default and reboot the switch.

Restore the previous configuration from a backup and reboot.

Downgrade individual packages using apt-get to match the previous version.
