CompTIA Server+ SK0-005 Release Date

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.

Scenario: Migrating a stand-alone application storing PII to the cloud.

Data to Encrypt: Data at rest (Option B) should be encrypted:

Data in transit (Option A) and backups (Option C) are also important but not the primary concern here.

Data archives (Option D) may or may not contain sensitive data.

A rescan on the server’s RAID controller is a possible troubleshooting step to detect the existing RAID configurations on the connected storage arrays. A firmware upgrade may cause the RAID controller to lose the RAID metadata or settings, and a rescan may restore them. A rescan is preferable to restoring the default RAID configuration, as the latter may erase the existing data on the arrays. Power cycling the storage arrays or booting the OS into recovery mode may not help if the RAID controller does not recognize the RAID sets.

iSCSI is a protocol that allows SCSI commands to be transmitted over IP networks, enabling remote access to storage devices. iSCSI uses IP addresses to identify and communicate with the storage array, so having multiple IP addresses for the array indicates that iSCSI is being used. eSATA, USB, and FC are other types of connections that use different protocols and connectors than iSCSI. References: CompTIA Server+ Certification Exam Objectives, Domain 3.0: Storage, Objective 3.1: Given a scenario, install and deploy primary storage devices based on given specifications and interfaces.
