Category: A+ Core 2 (220-1202)

The CompTIA A+ Core 2 (220-1202) examination tests the practical, day-to-day software and administrative skills required of modern technical support specialists. Entry-level and transitioning IT professionals must manage diverse client environments—including Windows, macOS, Linux, ChromeOS, and mobile operating systems—while defending systems against malware and adhering to strict change management protocols.

This category delivers structured study resources, practical walkthroughs, and performance-based question (PBQ) review material mapped directly to Core 2 exam domains. Explore step-by-step operating system recovery guides, command-line interface (CLI) cheat sheets, malware remediation procedures, and scripting basics to ensure you pass your exam and excel in operational support roles.

  • SY0-701 Lab: Linux Live-Response DFIR Triage

    A Linux web host is beaconing out. Do live-response triage: list processes to find the masquerading binary, find its C2 connection, uncover cron persistence, then kill the process to contain — collecting volatile evidence in the right order.

  • Architecting High Availability: Active-Active vs Active-Passive Clusters

    High availability (HA) keeps a service reachable when a node, a path, or a site fails.

  • CAS-005 Lab: Vault & Kubernetes Secrets Management

    Stop hardcoding database credentials in manifests. Store them in Vault’s KV engine, then create and verify a Kubernetes secret the app pod can mount.

  • Never Hardcode Secrets: Scaling Enterprise Secrets Management with HashiCorp Vault

    Hardcoded secrets turn source code, images, and pipelines into credential stores. CompTIA SecurityX (CAS-005) treats that as an identity problem and as an attack-surface problem. Domain 3.1 names secrets management as tokens, certificates, passwords, and keys, plus rotation and deletion.

  • 220-1202 Lab: Encrypting Drives with BitLocker & EFS

    The HR laptop stores sensitive files. Encrypt the whole OS drive with BitLocker (TPM + recovery key), then encrypt just the HR folder with EFS — and learn exactly when to reach for each.

  • Security Best Practices: BitLocker & EFS

    A stolen drive still holds every file on it unless the technician encrypted the data first. CompTIA A+ Core 2 (220-1202) groups three Windows controls for that job under objective 2.2: BitLocker, BitLocker-To-Go, and Encrypting File System (EFS).

  • 220-1201 Lab: MDM Configuration Basics

    The company is rolling out managed iPhones and Android tablets. Build the MDM security baseline: pick the policies that actually harden a fleet, then map MDM concepts and complete an enrollment profile.

  • Mobile Device Hardware & Screen Replacements

    A cracked lid is a ticket, not a 1.1 parts list. Core 1 asks you to monitor the hardware CompTIA names, pick the right replacement technique for those parts, and tell a broken panel apart from a dead digitizer, a dim backlight, or a swollen battery.

  • N10-009 Lab: HAProxy Load Balancing & Health Checks

    A single web server is a bottleneck and a SPOF. Inspect the HAProxy config, add a second backend server with round-robin balancing and health checks, validate, reload, and prove requests alternate across servers.

  • Wireless Networking: Wi-Fi 6, 7 & WPA3

    Wireless fails when the access point (AP) sits on a crowded channel, uses a weak passphrase, or advertises the same name as a rogue radio. CompTIA Network+ (N10-009) tests whether you can select the band, the channel plan, the encryption mode, and the AP type before clients join.
