Explanation
Overprovisioning is a situation where the allocated resources for a virtual machine exceed the available resources of the physical host. In this case, the storage allocated for Server 1 and Server 2 on VM01 is 8TB and 10TB respectively, which adds up to 18TB. However, the storage available on the VM01 host is only
16TB, which means there is a 2TB deficit. This can cause performance issues and errors for the virtual machines.

A 1000BASE-LX 1Gb single-mode plenum fiber connection would best meet the analyst's needs for a new point-to-point Ethernet connection between a university campus and a newly acquired space downtown that is about 5mi (8km) away. A 1000BASE-LX is a type of Ethernet standard that supports data transmission at 1 gigabit per second over single-mode fiber cables using long wavelength lasers. A single-mode fiber cable is a type of optical fiber cable that has a small core diameter and allows only one mode of light to propagate through it. A single-mode fiber cable can transmit data over long distances at high speeds, but it requires more expensive transceivers and connectors than multimode fiber cables. A plenum fiber cable is a type of optical fiber cable that has a special coating that prevents the spread of fire or toxic fumes in case of burning. A plenum fiber cable is suitable for installation in plenum spaces, which are areas used for air circulation in buildings, such as above ceilings or below floors.

g., network interface card failure), troubleshoot using appropriate tools.

An access control vestibule is a physical security concept that limits personnel access to a restricted area within a data center. It is a small room or hallway that has two doors: one that leads to the outside and one that leads to the restricted area. The doors are controlled by an electronic lock that requires authentication, such as a card reader, biometric scanner, or keypad. Only authorized personnel can enter the vestibule and access the restricted area. References: CompTIA Server+ Certification Exam Objectives, Domain 5.0:
Security, Objective 5.1: Given a scenario, apply physical security methods to a server.

A synthetic full backup is a type of backup that copies changed data from a server and then combines the backups on the backup target. This way, the backup target always has a full backup of the server, without requiring a full backup to be performed over the network. A synthetic full backup reduces the network bandwidth and time required for backups, while also simplifying the restoration process1

The most likely cause of the issue is that the server has not been joined to the domain. A domain is a logical group of computers and devices that share a common directory service and security policy. A domain controller is a server that manages the domain and authenticates users and computers that want to access domain resources. To log on with domain credentials, a server must be joined to the domain and registered in the directory service. If a server has not been joined to the domain, it will not be recognized or authorized by the domain controller.
