The system displays the following error:

cp: cannot create verybig: Disc quota exceeded

Which two are implemented using the Internet Control Message Protocol (ICMP)?

Show Answer Hide Answer
Correct Answer: A, F

The Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet Protocol Suite.

ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between systems, nor is it regularly employed by end-user network applications (with the exception of some diagnostic tools like ping and traceroute).

You have installed software updates to a new boot environment (BE) and have activated that the booting to the new BE, you notice system errors. You want to boot to the last known good configuration.

Which option would you use on a SPARC system to boot to the currentBE boot environment?

Show Answer Hide Answer
Correct Answer: F

You can change an inactive boot environment into an active boot environment. Only one boot environment can be active at a time. The newly activated boot environment becomes the default environment upon reboot.

How to Activate an Existing Boot Environment

1. Use the following command to activate an existing, inactive boot environment:

beadm activate beName

beName is a variable for the name of the boot environment to be activated.

Note the following specifications.

beadm activate beName activates a boot environment by setting the bootable pool property, bootfs, to the value of the ROOT dataset of the boot environment that is being activated.

beadm activate sets the newly activated boot environment as the default in the menu.lst file.

2. Reboot.

The newly activated boot environment is now the default on the x86 GRUB menu or SPARC boot menu.
