Q1. In a storage area network (SAN), the interconnected collection of HBAs, Fibre Channel switches, and storage devices forms a specific type of topology. What is this topology called?
Correct answer: A. Fabric
A SAN is divided into zones, and devices within the same zone can communicate with each other. The full collection of these zones, connected via routers and switches, is referred to as the SAN fabric.
Q2. Data centers must maximize the number of servers that fit within a given physical footprint. Which metric is used to evaluate how efficiently space is being utilized?
Correct answer: D. Density
Density refers to how many components are packed onto a physical board or blade. Higher density means more computing power per square foot, reducing costs for capital purchases and energy consumption.
Q3. You are planning to install a new network interface card into a physical server. What should you verify on the server first to ensure the card will be compatible?
Correct answer: C. PCI expansion slot
Network interface cards connect via PCI slots. Because different generations of NICs operate at different speeds and are designed for specific slot types, you must confirm the server has a compatible PCI expansion slot before installation.
Q4. Heavy server racks in data centers require floors capable of supporting significant weight. What safety practice is used to keep the racks from tipping over?
Correct answer: C. Bolting
Bolting racks to the floor is a data center best practice. In earthquake-prone or otherwise geologically unstable regions, anchoring racks is often a regulatory compliance requirement.
Q5. Mobile and consumer devices have limited power, cooling, and thermal capacity. Which type of processor instruction set architecture is typically used in these devices?
Correct answer: D. RISC
Reduced Instruction Set Computing (RISC) processors use a compact, highly-optimized instruction set, making them well-suited for devices with limited power and cooling budgets, such as mobile and consumer electronics.
Q6. A disk in a RAID group failed and was immediately replaced with a standby disk while the system continued operating without interruption. What is this procedure called?
Correct answer: D. Hot swapping
Hot swapping is the process of replacing or adding hardware components while the system remains powered on and fully operational, without any need to shut down or reboot.
Q7. Public cloud storage is attractive for its low cost and elastic scalability. However, some organizations cannot migrate all their data to the public cloud. What is the most common reason for this restriction?
Correct answer: D. Regulatory requirements
Many industries and countries enforce data protection, privacy, and data sovereignty laws that prohibit storing sensitive data in the public cloud. Government agencies, financial institutions, and healthcare organizations are common examples.
Q8. Rack-mounted equipment uses a standard height measurement abbreviated as "U," where 1U equals 1.75 inches. What is the total height in inches of a device rated at 4U?
Correct answer: D. Seven inches
Each rack unit (U) equals 1.75 inches. Multiplying 1.75 by 4 gives 7 inches, so a 4U device occupies seven inches of vertical rack space.
Q9. Storage area networks support business-critical, high-performance workloads. Which disk interface protocol is most commonly used in SANs to achieve the required performance levels?
Correct answer: D. FC
Fibre Channel (FC) is a high-speed data transfer protocol designed to deliver block-level data to applications with minimal latency. It is the standard interface used in commercial data center SANs. SAS, SCSI, and SATA are alternative disk interfaces used in other contexts.
Q10. Your data center storage supports mission-critical systems requiring high fault tolerance. Which disk interface supports hot swapping, allowing failed disks to be replaced without downtime?
Correct answer: B. SAS
Serial Attached SCSI (SAS) interfaces natively support hot swappable devices. If a disk fails, a replacement can be inserted while the system continues running, making SAS a fault-tolerant choice for critical storage environments.
