Free SK0-005 sample questions

1. A server technician is deploying 40 dual-socket nodes into a single data center rack and needs to maximize compute density and centralized power distribution per rack unit. Which server form factor best meets this requirement?

   • A. Tower server chassis
   • B. Rack-mount 4U chassis server
   • C. Blade server inside a high-density blade enclosure
   • D. Standalone pedestal server chassis
   Show answer

   Correct: C. Blade server inside a high-density blade enclosure is correct because blade chassis share redundant power, cooling, and network backplanes to deliver maximum compute density per rack unit. Tower server chassis and standalone pedestal server chassis are incorrect because they use free-standing enclosures not designed for rack density. Rack-mount 4U chassis server is incorrect because consuming 4U per node rapidly exhausts rack space.

2. A system administrator needs to replace a degraded hard drive in a production RAID 5 array without interrupting server operations or powering down the system. Which hardware feature enables this operation?

   • A. Hot-swap drive bays
   • B. Cold-spare drive provisioning
   • C. Wake-on-LAN (WoL) capability
   • D. Out-of-band management interface
   Show answer

   Correct: A. Hot-swap drive bays is correct because drive backplanes with hot-plug controllers permit drive insertion and removal while the storage controller and operating system remain active. Cold-spare drive provisioning is incorrect because cold spares require system shutdown before installation. Wake-on-LAN (WoL) capability is incorrect because it sends remote power-on network frames. Out-of-band management interface is incorrect because it provides remote console access rather than hot-pluggable disk bus operations.

3. A storage administrator is configuring a local array using four identical 4 TB disks. The business requirement dictates that the storage array must survive the simultaneous failure of any two disks without data loss. Which RAID level should be selected?

   • A. RAID 0 (Disk Striping without parity)
   • B. RAID 1 (Disk Mirroring)
   • C. RAID 5 (Disk Striping with single distributed parity)
   • D. RAID 6 (Disk Striping with dual distributed parity)
   Show answer

   Correct: D. RAID 6 (Disk Striping with dual distributed parity) is correct because it calculates two distinct parity blocks per stripe, enabling the volume to maintain data integrity during concurrent dual-drive failures. RAID 0 is incorrect because it provides no data redundancy. RAID 1 is incorrect because it only mirrors pair sets across two disks. RAID 5 is incorrect because single distributed parity only withstands a single drive failure.

4. A database administrator is designing storage for an online transaction processing (OLTP) server using six SAS drives. The workload demands high IOPS for write operations alongside fault tolerance. Which RAID configuration best balances these needs?

   • A. RAID 5 (Disk Striping with single parity)
   • B. RAID 6 (Disk Striping with dual parity)
   • C. RAID 10 (Striped Set of Mirrored Disks)
   • D. RAID 0 (Disk Striping without parity)
   Show answer

   Correct: C. RAID 10 (Striped Set of Mirrored Disks) is correct because combining RAID 1 mirroring with RAID 0 striping delivers fast write performance without the parity write penalty associated with parity RAID. RAID 0 is incorrect because it lacks fault tolerance. RAID 5 and RAID 6 are incorrect because parity calculations impose noticeable write performance penalties during database transaction writes.

5. During the initial firmware setup of a new dual-socket server, a system administrator must prepare the hardware to host a bare-metal Type 1 hypervisor and boot from a SAN LUN. Which firmware settings should be configured in UEFI? (Choose TWO)

   • A. Enable CPU hardware virtualization extensions (Intel VT-x / AMD-V)
   • B. Set the target boot device order in UEFI firmware settings
   • C. Configure guest operating system product licensing keys
   • D. Create virtual network switches inside the hypervisor management console
   Show answer

   Correct: A and B. Enabling CPU hardware virtualization extensions and setting the target boot device order are correct because both options are configured directly within the system BIOS/UEFI firmware interface prior to OS loading. Guest OS licensing keys and virtual network switch creation are incorrect because they are software configuration tasks performed inside the hypervisor OS operating layer.
