220-1101 Exam Results

Mobile Device Management (MDM) enables administrators to enforce controls on enterprise devices, such as restricting apps, ensuring compliance, and remotely managing security policies.

Why Not B (MFA): Multi-Factor Authentication secures user access but does not control device configurations.

Why Not C (VPN): VPN secures communication but does not enforce device controls.

Why Not D (SSL): SSL secures data in transit but does not provide device management.

CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.7, device management concepts​.

TPM 2.0 (Trusted Platform Module) is often disabled by default in the UEFI BIOS. Enabling it is necessary to meet the requirements for certain Windows installations, including Windows 11.

Why Not B (Install an HSM): A Hardware Security Module (HSM) is a separate device used for cryptographic functions and is not related to TPM on the motherboard.

Why Not C (Perform a clean install): A clean installation will not bypass the TPM 2.0 requirement.

Why Not D (Implement BitLocker): BitLocker requires TPM but does not resolve its absence or lack of activation.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 3.4, BIOS/UEFI configuration​.

Port 20 is used for FTP data transfer (along with port 21 for control), so enabling this port is required. Ports 23, 53, and 68 are unrelated to FTP functionality, as they correspond to Telnet, DNS, and DHCP respectively. CompTIA A+ Core 1 objectives outline the importance of knowing standard port numbers for network services.

An IP address starting with the first octet "169" immediately suggests an issue, indicating that the device has been assigned an Automatic Private IP Address (APIPA). APIPA addresses are self-assigned by a computer or device when it's unable to obtain an IP address from a DHCP server, which is common in situations where the device is unable to connect to the network or the DHCP server is not functioning properly. The range for APIPA addresses is 169.254.0.1 to 169.254.255.254, and seeing an IP address within this range is a clear indicator of connectivity issues related to DHCP.
