Section 1: Information Technology Fundamentals (Questions 1-20)
Q1: Which of the following storage technologies uses NAND flash memory and has no moving
parts, resulting in faster boot times and data access compared to traditional magnetic drives?
A. SATA HDD
B. SSD (Solid State Drive)
C. NVMe
D. RAID 5 Array
B. SSD (Solid State Drive) [CORRECT]
Correct Answer: B
Rationale: SSDs use NAND flash memory and have no moving platters, making them
significantly faster and more durable than SATA HDDs. While NVMe is a protocol often used
with SSDs, the defining characteristic of no moving parts compared to HDDs is the SSD itself.
RAID 5 is a configuration of multiple drives, not a storage technology type.
Q2: What is the primary difference between Type 1 (bare-metal) and Type 2 (hosted)
hypervisors?
A. Type 1 runs directly on hardware, while Type 2 runs on top of a host OS.
B. Type 2 allows for better resource allocation than Type 1.
C. Type 1 is only used for Linux, while Type 2 is used for Windows.
D. Type 2 runs directly on hardware, while Type 1 runs on top of a host OS.
A. Type 1 runs directly on hardware, while Type 2 runs on top of a host OS. [CORRECT]
,2
Correct Answer: A
Rationale: Type 1 hypervisors (e.g., VMware ESXi, Microsoft Hyper-V) install directly on the
system hardware, providing better performance and security. Type 2 hypervisors (e.g., VMware
Workstation, VirtualBox) run as software applications on top of a host operating system.
Q3: Which RAID level offers the best performance by striping data across multiple drives but
provides no fault tolerance?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
A. RAID 0 [CORRECT]
Correct Answer: A
Rationale: RAID 0 stripes data across two or more drives to improve speed (I/O operations per
second), but if one drive fails, all data is lost because there is no redundancy or parity. RAID 1
mirrors data, and RAID 5/10 provide fault tolerance.
Q4: In the context of operating systems, which file system is required for installing Windows 11
and supports features like file encryption and disk quotas?
A. FAT32
B. exFAT
C. NTFS
D. ext4
C. NTFS [CORRECT]
Correct Answer: C
Rationale: NTFS (New Technology File System) is the standard file system for Windows,
supporting security features (ACLs), encryption (BitLocker/EFS), compression, and large file
sizes. FAT32 and exFAT have file size limits (4GB for FAT32) and lack security features.

Q5: Which backup strategy involves copying all data that has changed since the last full backup,
regardless of any intermediate backup jobs?
A. Full Backup
B. Differential Backup
C. Incremental Backup
D. Snapshot
B. Differential Backup [CORRECT]
Correct Answer: B
Rationale: A differential backup copies all data changed since the last full backup. It is faster than
a full backup but requires more storage space and longer restore time than an incremental
backup. An incremental backup only copies data changed since the last backup (whether full or
incremental).
Q6: What is the function of the Central Processing Unit (CPU) component known as the
"Cache"?
A. Long-term storage of user files
B. High-speed volatile memory that reduces the time the CPU waits for data from RAM
C. Management of network traffic
D. Cooling the processor core
B. High-speed volatile memory that reduces the time the CPU waits for data from RAM
[CORRECT]
Correct Answer: B
Rationale: CPU cache (L1, L2, L3) is extremely fast memory located on or near the CPU core. It
stores frequently accessed data to prevent the CPU from idling while waiting for slower main
system RAM.
Q7: In cloud computing, what does the "SaaS" model stand for?
, 4
A. Security as a Service
B. Software as a Service
C. Storage as a Service
D. Structure as a Service
B. Software as a Service [CORRECT]
Correct Answer: B
Rationale: SaaS (Software as a Service) delivers applications over the internet (e.g., Microsoft
365, Google Workspace). IaaS provides infrastructure (servers, storage), and PaaS provides a
platform for developers.
Q8: Which of the following describes a "Container" in the context of virtualization?
A. A fully isolated virtual machine with its own OS kernel.
B. A lightweight, standalone package of software that includes everything needed to run an
application, sharing the host OS kernel.
C. A physical server dedicated to a single task.
D. A type of hypervisor.
B. A lightweight, standalone package of software that includes everything needed to run an
application, sharing the host OS kernel. [CORRECT]
Correct Answer: B
Rationale: Containers (e.g., Docker) are more lightweight than full Virtual Machines (VMs)
because they share the host operating system's kernel, allowing for faster startup and greater
density on hardware.
Q9: Which programming concept allows a class to inherit properties and methods from another
class, promoting code reusability?
A. Encapsulation
B. Polymorphism
