CompTIA Exam Prep - ITF+, A+, Network+, Security+, CySA+

Nearly every enterprise breach retrospective these days turns up the same culprit somewhere in the chain: a vendor, a subcontractor, or an open-source dependency nobody was watching closely enough. CompTIA's SecurityX (CAS-005) exam treats this reality as core architecture work, not an afterthought bolted onto procurement. Objective 1.2, inside the Governance, Risk, and Compliance domain — worth 20% of the exam — asks candidates to "perform risk management activities" against a named set of organizational requirements, and third-party risk sits squarely inside that objective alongside supply chain risk, vendor risk, and subprocessor risk. This guide breaks down what SecurityX expects you to know about managing risk that lives outside your own network boundary, building on the enterprise architecture and operations concepts covered in our Zero Trust Architecture for CAS-005 guide and our look at Enterprise Data Loss Prevention strategies . Why Third-Party Risk Gets It...

Software licensing rarely gets the attention that hardware or networking topics do, but CompTIA puts it squarely inside the Security domain of the Tech+ (FC0-U71) exam, which carries a hefty 19% weight — the second-largest domain on the test. Objective 6.1 expects candidates to explain basic software licensing concepts, including open source versus proprietary models, end user license agreements (EULAs), product keys, and the difference between a one-time purchase and a recurring subscription. These concepts come up constantly in real IT work too: every time you install an application, renegotiate a renewal, or onboard a new employee's laptop, a licensing decision is sitting underneath it. This guide builds on the ideas introduced in our Security Fundamentals for CompTIA Tech+ article, which covers the CIA triad and AAA, and pairs naturally with our breakdown of Virtualization and Cloud Computing Fundamentals , since cloud services are almost always sold under subscription lic...

CompTIA SecurityX (CAS-005) treats Zero Trust as far more than a buzzword. Objective 2.6, "Integrate Zero Trust concepts into architecture," sits inside the Security Architecture domain — worth 27% of the exam, the single heaviest domain on the test — and it expects candidates to reason about continuous authorization, context-based reauthentication, segmentation and microsegmentation, always-on VPN, asset attestation, security boundaries, deperimeterization, and subject-object relationships at an enterprise-architect level. This is a meaningful step up from the Zero Trust vocabulary tested on Security+ and Network+. This guide walks through each of those CAS-005 sub-concepts, building on the policy engine and policy administrator model from our NIST SP 800-207 breakdown and our Zero Trust Architecture primer . Why CAS-005 Pushes Zero Trust Further Than SY0-701 Security+ candidates need to recognize the Policy Decision Point / Policy Enforcement Point model and define ter...

Why Storage Types Matter on the Tech+ Exam CompTIA Tech+ (FC0-U71) Domain 2.0, Infrastructure, asks candidates to distinguish between the many kinds of storage a modern IT environment uses — from the volatile memory inside a running computer to the cloud buckets a business backs its files up to. This is one of those topics that looks simple on the surface but trips up new candidates because the exam likes to test the distinctions : volatile versus non-volatile, local versus network, and block versus file-level access. Get the categories straight and the specific device names (HDD, SSD, NVMe, NAS, SAN) fall into place naturally. This guide walks through every storage category Tech+ expects you to know, explains how each one is actually used in the field, and closes with exam-style scenarios so you can practice telling them apart. If you haven't already, it's worth reviewing the Computer Internal Components guide first, since storage is one of the six core components discussed...

Enterprise Data Loss Prevention (DLP) is one of those CompTIA SecurityX (CAS-005) topics that sounds simple on the surface — "stop sensitive data from leaving the organization" — but turns into a scenario-heavy nightmare once the exam starts mixing in deployment models, detection methods, and integration points with CASB, SWG, and SASE. CAS-005 expects security architects to design DLP programs that scale across endpoints, networks, email, and cloud services, not just define the acronym. This guide walks through how enterprise DLP actually works, where it gets deployed, how it detects sensitive data, and what SecurityX wants you to recognize when a scenario question drops you into the middle of a DLP rollout or a tuning problem. What Enterprise DLP Actually Does At its core, DLP is a set of technologies and policies that identify, monitor, and control the movement of sensitive data — intellectual property, PII and PHI , financial records, source code — so it c...

CompTIA Tech+ (FC0-U71) devotes nearly a quarter of the exam to the Infrastructure domain, and a large chunk of that domain comes down to one deceptively simple question: how do devices actually talk to each other and to the people using them? Candidates who can recite CPU specs or RAM types sometimes stumble when asked to pick the right cable for a 4K monitor or explain why a wireless mouse keeps dropping its connection. This guide walks through the wired and wireless connection interfaces Tech+ expects you to know, then covers the peripheral setup skills — printers, scanners, and monitors — that show up just as often on the real exam. Why Connection Interfaces Matter on the Tech+ Exam FC0-U71's Infrastructure objectives explicitly call out "device connection interfaces" alongside computing device types and internal hardware, which we covered in our guide to common computing devices and our breakdown of internal components . The exam is not asking you to become a cab...

Enterprise security teams no longer get to review an application after it ships. CompTIA's SecurityX (CAS-005) exam reflects that reality by testing whether candidates can build security into the software development lifecycle itself — not bolt it on afterward. This is the discipline known as DevSecOps , and it shows up across the exam's security architecture and security engineering objectives as a scenario-based topic: pipeline hardening, automated testing, dependency management, and infrastructure-as-code (IaC) security. This guide walks through what DevSecOps and secure SDLC integration actually mean in practice, how the pieces fit together, and what SecurityX expects you to recognize on exam day. Why DevSecOps Matters for SecurityX (CAS-005) Traditional application security review happened at the end of a release cycle, often as a single gate before production. That model breaks down when releases ship daily or hourly. DevSecOps answers the problem by treating securit...

Every device on a network — whether it's the laptop on your desk or the smart thermostat in your hallway — needs three things to talk to other devices: an address, a way to be reached on that address, and an agreed network to be part of. CompTIA Tech+ (FC0-U71) tests exactly this under Domain 2.0 (Infrastructure), in the objective that asks candidates to identify basic networking concepts. It's one of the highest-value sections on the exam, because almost everything that comes later — wireless, cloud, even security — assumes you already understand how two devices find and talk to each other in the first place. This guide walks through the building blocks of basic networking the way Tech+ expects you to know them: network types, the client-server model, IP addressing, MAC addressing, and the ports that let many services share one connection. By the end, you'll be able to trace a request from your laptop to a website and back, naming every piece along the way. Why Network...

Mobile devices now sit on the same attack surface as laptops and servers, but they are provisioned, patched, and monitored through a completely different stack. For CompTIA SecurityX (CAS-005) , "managing enterprise mobility" is called out explicitly under the Security Engineering domain, and it shows up on the exam as scenario questions about device enrollment, containerization, and conditional access policy. This post walks through the vocabulary and the architecture decisions a SecurityX candidate needs to recognize, and ties each concept back to exam-style framing. Why Enterprise Mobility Belongs on the SecurityX Exam Earlier CompTIA certifications treat mobile security mostly as a device-hardening topic: screen locks, remote wipe, full-disk encryption. SecurityX goes a layer deeper. It expects candidates to evaluate an entire mobility program — the enrollment workflow, the policy engine that enforces compliance, the way corporate data is isolated from personal data, ...

Before you can troubleshoot a device, configure it, or secure it, you have to recognize what it is and what it's built to do. That recognition is exactly what Domain 2.0 (Infrastructure) of the CompTIA Tech+ (FC0-U71) exam tests first, and objective 2.1 specifically asks candidates to identify common computing devices and their purposes. This single objective quietly underpins a huge share of the rest of the exam: you can't talk about internal components, storage types, or wireless connectivity without first knowing which device you're talking about. This guide walks through every device category FC0-U71 expects you to recognize — phones, tablets, laptops, servers, IoT devices, VR/AR systems, and wearables — and explains the distinguishing traits CompTIA wants you to be able to call out on exam day. Why Device Identification Matters on the Tech+ Exam Domain 2.0 carries the single largest weight on the FC0-U71 exam at 24%, and it opens with device recognition before mo...
