1Which component of a computer is responsible for executing instructions?

A.RAM

B.Hard disk drive

C.CPU

D.Power supply

Explanation: The CPU (Central Processing Unit) executes instructions by fetching, decoding, and executing them. RAM holds data/instructions temporarily for fast access. The HDD/SSD stores data long-term. The power supply delivers electrical power but does not execute instructions.

2Which is a volatile form of memory?

A.SSD

B.HDD

C.RAM

D.ROM

Explanation: RAM (Random Access Memory) is volatile — it loses contents when power is removed. SSDs, HDDs, and ROMs are non-volatile. This distinction matters for forensics: volatile memory must be captured first when collecting evidence from a live machine.

3What does 'BIOS' stand for and what does it do?

A.Basic Input/Output System — initializes hardware at boot

B.Binary Input/Output Standard — encodes binary data

C.Boot Integrity Operating Security — secures the OS

D.Background Interface for Operating Systems — runs services

Explanation: BIOS (Basic Input/Output System) firmware initializes and tests hardware when a computer powers on, then loads the boot loader. UEFI is the modern replacement, offering a larger partition size limit (GPT), secure boot, and a graphical interface.

4Which file system is native to modern Windows installations?

A.ext4

B.NTFS

C.HFS+

D.APFS

Explanation: NTFS (New Technology File System) is Microsoft's primary file system for Windows, supporting permissions, encryption (EFS), compression, journaling, and large files. ext4 is Linux, HFS+/APFS are macOS. Understanding file systems matters for forensics and data recovery.

5What is an operating system?

A.The CPU's firmware

B.Software that manages hardware resources and provides services to applications

C.A programming language

D.A networking protocol

Explanation: An operating system (Windows, Linux, macOS) manages CPU scheduling, memory, file systems, devices, and provides APIs to applications. Core components: kernel, drivers, system libraries, shell, and user interfaces.

6Which Linux command lists files in the current directory?

A.cd

B.ls

C.pwd

D.mv

Explanation: ls lists files and directories in the current (or specified) directory. cd changes directory, pwd prints the working directory path, and mv moves/renames files. Common flags: -l (long), -a (show hidden), -h (human-readable sizes).

7What does a hypervisor do?

A.Encrypts files

B.Allows multiple virtual machines to share a physical host

C.Manages Active Directory

D.Serves web pages

Explanation: A hypervisor (Type 1 like ESXi/Hyper-V or Type 2 like VirtualBox) abstracts physical hardware to run multiple virtual machines, each with its own OS. This underpins cloud computing, development environments, and server consolidation.

8Which container platform popularized the Dockerfile format?

A.Kubernetes

B.Docker

C.Podman

D.Vagrant

Explanation: Docker popularized containerization and the Dockerfile build spec. Kubernetes orchestrates containers at scale, Podman is a daemonless Docker alternative, and Vagrant manages VM dev environments. A Dockerfile is a declarative recipe for building container images.

9Which cloud service model provides full infrastructure (VMs, storage, networking)?

A.SaaS

B.PaaS

C.IaaS

D.FaaS

Explanation: IaaS (Infrastructure as a Service — AWS EC2, Azure VMs, GCP Compute Engine) provides virtualized compute, storage, and networking. PaaS provides managed platforms (App Service, Heroku), SaaS provides software (Gmail, Salesforce), FaaS provides serverless functions.

10In the shared responsibility model for cloud, which of these does the customer ALWAYS own?

A.Physical data center security

B.Hypervisor patching

C.Data classification and access management

D.Switch firmware updates

Explanation: Regardless of IaaS/PaaS/SaaS, the customer always owns data classification, identity and access management for their users, and data handling. The provider handles physical, hypervisor, and (in PaaS/SaaS) the platform/application stack.

About the ITCA Exam

The Information Technology Certified Associate (ITCA) is ISACA's foundational, entry-level IT and cybersecurity credential. Candidates earn the full ITCA by passing all five individual domain exams: Computing Fundamentals, Networks and Infrastructure, Cybersecurity, Software Development, and Data Science. Each domain exam stands as its own stackable micro-credential. There are no prerequisites.

ITCA Study Tips from Top Performers

1Take Computing Fundamentals first — it provides foundational context for the other four domains

2For Networks: memorize the OSI model layers and master subnetting with /24, /25, /26, /27 examples

3For Cybersecurity: know the CIA triad inside-out and understand symmetric (AES) vs asymmetric (RSA, ECC) vs hashing (SHA-256, bcrypt)

4For Software Development: practice Python basics on free platforms (Codecademy, freeCodeCamp) and learn Git commands

5For Data Science: practice SQL SELECT/JOIN/GROUP BY queries and understand mean, median, mode, standard deviation

6Use ISACA's official study materials and free Microsoft Learn or Cisco Networking Academy for supporting content

Frequently Asked Questions

What is the ITCA certification?

The Information Technology Certified Associate (ITCA) is ISACA's foundational IT certification for students, career changers, and early-career professionals. It is earned by passing five domain exams (Computing Fundamentals, Networks and Infrastructure, Cybersecurity, Software Development, and Data Science). Each domain earns a stackable credential; passing all five earns the full ITCA.

How much does ITCA cost?

Each ITCA domain exam costs approximately $199 USD. To earn the full ITCA credential you must pass all five domains, bringing the total to approximately $995. Candidates can take the exams in any order and at their own pace — no time limit applies between domains.

Are there prerequisites for ITCA?

No — ITCA is designed for beginners with no prior IT experience. There are no formal education, work experience, or certification prerequisites. This makes it an ideal first professional IT credential for students, career changers, and those entering cybersecurity.

Which ITCA domain should I take first?

Most candidates start with Computing Fundamentals because it covers foundational concepts (hardware, operating systems, cloud) that support the other domains. Networks and Infrastructure is typically next, followed by Cybersecurity. Software Development and Data Science can be taken in any order after the first three.

How long should I study for each ITCA domain?

Plan for 30-50 hours per domain depending on your background. Computing Fundamentals and Cybersecurity may take 30-40 hours for beginners. Software Development and Data Science typically require 40-60 hours if you have no programming or statistics background. Most candidates complete all five domains in 4-8 months.

What jobs can I get with ITCA?

ITCA is designed to demonstrate foundational IT knowledge and can help you qualify for entry-level roles: IT Support, Help Desk Technician, Junior SOC Analyst, Jr. Systems Administrator, IT Intern, or Technical Support. It is a stepping stone to higher ISACA credentials like CCOA, CISA, CISM, or other vendor certifications.
