The system date/time is maintained by the CMOS battery when the PC is powered off. If this battery fails, time resets will occur. Additionally, since the system is connected to a UPS, ensuring the UPS is functioning correctly (i.e., the backup power source) is essential.

Mobile Device Management (MDM)software often controls access to corporate resources based onlocation, network, or VPN status. If the MDM is not configured to allow access from outside the office or via home networks, the apps may be blocked. This is the most probable cause if apps work only on-premises.

Option A:GPS is used for location services, not access control.

Option C:WPA is a Wi-Fi security protocol, not related to access restrictions.

Option D:NFC enables close-range communication irrelevant to app access.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.6: Given a scenario, configure basic mobile device network connectivity and application support.

To provision and run multiple virtual machines on a physical server, the administrator must use a hypervisor. A hypervisor is the virtualization layer that creates, runs, and manages virtual machines by abstracting physical hardware resources such as CPU, RAM, storage, and network adapters into virtual resources presented to each VM. Once the server is configured with the required hardware support (such as sufficient RAM/CPU capacity and virtualization features enabled in firmware), the hypervisor is the component that enables VM creation, allocation of resources, virtual disk creation, and VM lifecycle actions like start, stop, suspend, snapshots, and virtual networking configuration.

Device Manager is used to view and manage hardware devices and drivers on an operating system, but it is not a VM provisioning tool. Disk Management can partition and format disks, which may support storage preparation, but it does not create or run VMs. A Virtual LAN is a network segmentation method at Layer 2 and may be used in VM networking designs, but it does not provide virtualization itself. Therefore, the correct tool for provisioning virtual machines is the hypervisor.
