What is GPT (GUID Partition Table)?
This server role translates human-readable domain names into IP addresses.
What is DNS (Domain Name System)?
This RAID level provides striping without redundancy, offering 100% usable capacity but no fault tolerance.
What is RAID 0?

What is vmbr0?
What does POST stand for and what does it check?
A diagnostic process performed by the firmware during startup to verify that critical hardware components (CPU, RAM, storage) are functioning correctly.
This type of hypervisor runs directly on physical hardware without an underlying operating system.
What is a Type 1 hypervisor (bare-metal)?
This default port is used by SSH for secure remote command-line access.
What is port 22?
This enterprise drive interface supports full-duplex communication and a command queue depth of 256.
What is SAS (Serial Attached SCSI)?
This percentage of CPU ready time is considered healthy for a VM.
What is below 5%?
This type of RAM detects and corrects single-bit memory errors, making it essential for enterprise servers
What is ECC RAM?
This network protocol allows a server to boot and install an operating system over the network using DHCP and TFTP.
What is PXE (Preboot Execution Environment)?
In the DHCP DORA process, this step occurs when the server proposes an IP address to the client.
What is Offer?

What is iDRAC (Integrated Dell Remote Access Controller)?
This open-source Type 1 hypervisor combines KVM for virtualization and LXC for containers, managed via a web interface.
What is Proxmox VE?
This out-of-band management technology is HPE's equivalent to Dell's iDRAC.
What is iLO (Integrated Lights-Out)?
This two-part acronym stands for the unique identifier assigned to an iSCSI target.
What is IQN (iSCSI Qualified Name)?
