An administrator is managing an IOx application that has been running for several weeks. They need to upgrade the application to a new version. The new version is packaged as a .pak file. What is the correct procedure to upgrade the application?

Stop, deactivate, uninstall the old version, then install and activate the new version

Reboot the switch and then install the new version

Activate the new version while the old one is still running

Install the new version over the old one without stopping it

What happens when an IOx application is deactivated?

The application is stopped but remains installed.

The application's configuration is deleted.

The application is paused and can be resumed without reactivation.

The application is permanently removed from the device.

A network engineer is monitoring the resource usage of an IOx application on a Catalyst 9000 switch. They notice that the application is using more memory than expected and could potentially impact the switch's performance. What should they do to prevent this?

Move the application to a different VRF

Disable the application's logging to reduce memory usage

Reboot the switch to clear the memory

Set a memory limit for the application in its resource profile

Why is it important to monitor resource usage of hosted applications on network devices?

To increase the number of VLANs on the device

To reduce the device's power consumption

To prevent applications from consuming excessive resources that impact network performance

To improve the device's routing protocol convergence
