10. Refer to the exhibit.

A network administrator views the configuration files on an ArubaOS switch and sees the output in the exhibit. The administrator enters this command: Switch# boot system flash primary config config2 After the switch boots, the administrator makes some configuration changes and saves the configuration with the write memory command. The administrator then enters this command: Switch# boot After the switch boots, the configuration changes just made are not present.

How can the administrator restore the configuration with the changes?

Use the boot set-default command to configure the switch to use the secondary software. Then reboot the switch.

Reboot the switch and interrupt the boot process. Find the temporary file with the configuration changes and apply that file to the startup-config.

Rename the config2 file to config1. Then reboot the switch.

Use the startup-default command to configure the switch to use the config2 file with the primary software. Then reboot the switch.

Only the commander runs routing protocols and builds the IP routing table, and all routed traffic must pass through the commander.

Both members run routing protocols and build their own IP routing tables, and they synchronize the tables over VSF links.

16. A server connects to a port on an ArubaOS switch. The network administrator wants to ensure that the port remains forwarding during MSTP topology changes, and changes in the port status do not cause MSTP topology changes.

20. A company has a single routing protocol environment.

What is one reason to use OSPF routing instead of static routing?

OSPF allows ArubaOS switches to use default routes, while static routes cannot use 0.0.0.0/0 as the destination network.

OSPF has a lower default administrative distance than static routing on ArubaOS switches.

OSPF reduces the risk of accidentally introducing routing loops, while static routing does not.

OSPF permits load sharing traffic over multiple routes, while static routing does not.
