CompTIA Tech+ (FC0-U71) Practice Exam

Correct: A — 26. Hexadecimal is base 16, so 1A = (1 × 16) + (A, which is 10) = 16 + 10 = 26. Notational-system conversion between binary, hexadecimal and decimal is a named V6 objective.

Why not the others: 16 (B) is just the value of the leading digit’s place, ignoring the A. 32 (C) would be 2 × 16, treating the first digit as 2. 110 (D) is the binary-to-decimal result for 1101110 or a misread — it does not follow from base-16 place value.

Correct: B — establish a plan and implement the solution. Once a theory is confirmed, the methodology moves to establishing a plan of action and implementing the fix. The ordered steps are exactly what this objective tests.

Why not the others: Documenting (A) is the final step, after the fix is verified. Identifying the problem (C) has already happened — it is the first step, not the one after confirming a theory. Establishing a new theory (D) only applies if the theory had been disproven; here it was confirmed.

Correct: C — NVMe SSD. NVMe drives are solid-state (no moving parts) and communicate over the PCIe bus, giving them the highest throughput of the local options the objective lists. That combination is exactly what the requirement describes.

Why not the others: An HDD (A) has spinning platters and a moving head — it has moving parts and is far slower. NAS (B) is network storage, not local, so it fails the “directly on the workstation” requirement. An optical drive (D) is slow removable-media storage, not fast local storage.

Correct: D — SaaS. SaaS delivers finished applications over the internet with the provider managing everything beneath them, which is precisely “use the software without maintaining servers or apps.” Cloud service models are a named V6 objective.

Why not the others: IaaS (A) provides raw compute and storage that the customer must still build on. PaaS (B) gives developers a platform to deploy their own applications — more management than the business wants. On-premises (C) is the opposite of the requirement: they would own and maintain everything.

Correct: A — private browsing. Private or incognito mode is designed so that history, cookies and cached files from the session are not retained locally once the window is closed — exactly the requirement. Web-browser features including private browsing and cache clearing are a listed objective.

Why not the others: An ad-blocker (B) filters ads but does nothing about local history. Manual cache clearing (C) is error-prone and misses cookies and history unless each is cleared separately. Bookmarking (D) actively stores a reference on the machine, the opposite of what is wanted.

Correct: A — generative AI. Generative AI produces new content — text, images, and more — from prompts, which is what the tool does. The V6 refresh added generative AI to the applications and software domain explicitly.

Why not the others: A fixed-response chatbot (B) selects from pre-written replies rather than generating new content. OCR (C) reads existing text from images; it does not create anything. A spam filter (D) classifies existing messages into categories — classification, not generation.

Correct: C — an array. An array stores an ordered collection of values under one name, each reachable by an index — precisely the twelve-monthly-totals case. Arrays are a named programming concept in the objective.

Why not the others: A constant (A) holds one fixed value that never changes. A single variable (B) holds one value at a time, not twelve indexed ones. A function (D) is a reusable block of code that performs a task — it is not a data container.

Correct: D — a foreign key. A foreign key in the orders table points at the primary key of the customers table, enforcing that each order references a customer that actually exists. Primary and foreign keys are a listed database concept.

Why not the others: A primary key on the orders table (A) uniquely identifies each order but says nothing about the customer relationship. A non-relational store (B) is a different database model, not a relationship-enforcement element. A backup schedule (C) protects data but has nothing to do with referential links.

Correct: B — HTTPS. HTTPS encrypts data in transit between the browser and the server, so intercepted traffic is unreadable. Encryption for data at rest and in transit, including HTTPS, is a named security objective.

Why not the others: Strong passwords (A) protect account access, not the confidentiality of traffic on the wire. Anti-malware (C) defends the server host but does not encrypt the connection. Backups (D) protect against data loss, not interception.

Correct: C — confidentiality. Confidentiality is about restricting access to information to authorised parties; an unauthorised person reading records is the textbook confidentiality breach. The CIA triad is a foundational security objective.

Why not the others: Integrity (A) concerns whether data has been altered, not who can read it. Availability (B) concerns whether authorised users can access data when needed. Non-repudiation (D) is a related security concept but is not one of the three core CIA principles the question asks about.
