PXE (Preboot eXecution Environment) boot is an orchestration tool that allows a desktop administrator to deploy a standard image to multiple computers over a network. It requires a PXE server that hosts the image and a PXE client that boots from the network interface card (NIC). USB drive and DVD installation media are not orchestration tools, but manual methods of installing an image on each computer individually. Recovery partition is not an orchestration tool, but a hidden partition on the hard drive that contains an image of the factory settings. Verified References:

When a smartphone is lost, especially one that might contain sensitive or private data, the primary concern is to ensure that any data on the device cannot be accessed by unauthorized persons. Among the options provided:
* Remote lock: This option will lock the device remotely, preventing access. However, it does not remove the data and might not be effective if the device is powered off or reset.
* Remote wipe: This is the best option as it allows the technician to erase all data from the device remotely, ensuring that sensitive information is not accessible to anyone who finds or steals the device.
* Remote access: This option would allow a technician to access the device remotely, but it would not directly prevent unauthorized access or data breaches.
* Remote encrypt: Encrypting the device remotely might not be possible if the device is not accessible or turned on, and it does not remove existing data which could be at risk.

Explanation
Resetting the network adapter is the best way to apply the changes made to the hosts file on a few PCs. The hosts file is a text file that maps hostnames to IP addresses and can be used to block certain domains by redirecting them to invalid or local addresses. Resetting the network adapter will clear the DNS cache and force the PC to use the new entries in the hosts file.
