CompTIA Server+ (SK0-005)Server Hardware Installation and ManagementHard
A server administrator needs to upgrade the firmware on several mission-critical servers remotely. The servers are currently running on an older firmware version that requires a specific boot order and manual intervention for previous updates. To streamline future updates and enable more advanced remote management capabilities, which firmware interface should the administrator ensure is available and properly configured?
- AUEFI (Unified Extensible Firmware Interface)
- BPXE (Preboot Execution Environment)
- CLegacy BIOS
- DIPMI (Intelligent Platform Management Interface)
Show answer & explanationAnswer & explanation
Correct answer: A. UEFI (Unified Extensible Firmware Interface)
UEFI offers significant advantages over Legacy BIOS, including support for larger boot drives (GPT), faster boot times, and a more robust and flexible interface that often integrates with or facilitates more advanced remote management features for firmware updates and system configuration.
Why the other options are wrong
- B. PXE is a network booting standard, primarily used for deploying operating systems over the network, not for managing or updating server firmware directly.
- C. Legacy BIOS has limitations such as MBR partition table support (2TB drive limit), slower boot, and a text-based interface that lacks advanced remote management capabilities for firmware.
- D. IPMI is a hardware-level interface for out-of-band management (monitoring, power control, KVM over IP) but it is a management protocol/interface, not the core firmware interface that UEFI replaces or enhances.
UEFI (Unified Extensible Firmware Interface)
A modern firmware interface that replaces the traditional BIOS. UEFI provides enhanced capabilities such as support for large hard drives (GPT), faster boot times, secure boot, and a more flexible pre-boot environment, often with a graphical interface.
- Replaces Legacy BIOS.
- Supports GPT partition tables (drives > 2TB).
- Enables Secure Boot for enhanced security.
- Offers a more advanced and extensible pre-boot environment.
