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.

A hybrid cloud combines private infrastructure (on-premises, self-operated data centers) with public cloud services, providing flexibility and scalability.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Cloud concepts:

“A hybrid cloud model integrates private and public cloud infrastructure to allow applications and data to be shared between them.”

============

BitLocker Drive Encryption in Windows requires aTrusted Platform Module (TPM)to encrypt the boot drive securely. The TPM is a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. It validates system integrity during boot and securely stores the encryption keys. If BitLocker cannot find a TPM or it is disabled in BIOS/UEFI, drive encryption cannot proceed.

BitLocker can function without TPM using a USB startup key, but this compromises some security and is not recommended for managed enterprise environments.

ECC (Error-Correcting Code) RAM is commonly used in servers to provide error detection and correction, improving reliability in critical systems. It is designed to detect and correct single-bit errors, ensuring data integrity in environments where stability is paramount.

Option A (SODIMM): Incorrect. SODIMM is typically used in laptops, not servers.

Option B (Rambus): Incorrect. Rambus is an outdated RAM type and not commonly used today.

Option C (DDR3): Incorrect. While DDR3 is a type of RAM, it is not specific to servers and does not provide error correction.
