220-1202 — frequently asked questions

OS upgrades can reset security tokens, certificates, or provisioning profiles that the MDM agent relies on to verify device identity and compliance.

No. Restarting clears temporary states but does not re-authenticate the device with the MDM server. Re-enrollment is required to establish a new trust relationship.

Game consoles often require multiple open ports for chat and matchmaking. Placing them in the screened subnet isolates these risks from the internal LAN, protecting personal data on other devices.

The Wireless AP should use a static private IP address within the LAN subnet range (e.g., 192.168.1.x). It should not use an APIPA address (169.254.x.x) as that indicates a lack of DHCP connectivity.

No. Robocopy is a file-level copy utility. It cannot replicate partition structures, boot sectors, or system registry hives required for a bootable operating system.

Both are command-line file copying tools. Robocopy offers more features like mirroring, multi-threading, and resume capability, but neither performs disk imaging.

Remote wipe requires an active command to be sent to the device. If the user is unaware the phone is lost, they cannot send this command, leaving the data vulnerable until the loss is discovered.

No. Facial recognition only secures the login process. If the device is already unlocked or if the attacker accesses the file system directly, biometrics offer no protection for the data at rest.

The problem is battery discharge during use, not charging. Checking the port addresses connectivity, not drain. Software utilization directly impacts power consumption.

No. Since the phone was recently replaced, the battery should be healthy. Diagnostic steps should focus on software causes like rogue apps before hardware replacement.

Yes, using registry edits or command-line tools during installation, but this is not recommended for production environments and may void support.

Modern systems often use Firmware TPM (fTPM) or PTT, which appear as TPM devices in BIOS/UEFI but might not show up as a discrete hardware chip in Device Manager.

'Net view' lists shared resources on a remote computer without mapping them locally. 'Net use' actively connects a local drive letter to a remote share, making it accessible via File Explorer.

Yes, you can use the New-SmbGlobalMapping cmdlet in PowerShell. However, the CompTIA A+ exam often focuses on traditional CMD commands like 'net use' for basic troubleshooting scenarios.

Testing is a technical validation step that should only occur after the change has been formally requested, reviewed, and approved through the change management process.

Request forms document the proposed change, allowing stakeholders to assess risk, schedule maintenance windows, and authorize the deployment before it happens.
