The state in which Mark encrypted the data in the above scenario is data in use. Data in use refers to data that is being processed or manipulated by an application or a system, such as data stored on RAM or CPU registers. Data in use is the most vulnerable state of data, as it is exposed to various threats, such as memory scraping, buffer overflow, or side-channel attacks, that can compromise the confidentiality, integrity, or availability of the data. Data in use encryption is a technique that protects the data while it is being processed by encrypting it in memory using hardware or software solutions. Data in use encryption prevents unauthorized access or modification of the data, even if the system is compromised or the memory is dumped.Data in use encryption is one of the three types of data encryption, along with data at rest encryption and data in transit encryption123.References:

A wireless repeater is a wireless network component that takes a signal from one access point and boosts its signal strength to create a new network. A wireless repeater can extend the range of a wireless network by repeating the signal from the original access point. This way, the wireless repeater can provide network connectivity to areas that are inaccessible to capture direct signals from the access point.In the scenario, Robert used a wireless repeater to provide network connectivity to all areas12.References:Network Defense Essentials - EC-Council Learning,Understanding the Wireless Network Components
