Operating Systems1 / 5

A Windows workstation has two NICs (network interface cards) -- one wired and one wireless. Both are connected to the same network. Which Windows setting determines which NIC is used for network traffic by default?

AlexFull explanation from Alex

Windows uses the interface metric to determine which NIC handles default network traffic when multiple adapters are connected. A lower metric value indicates higher priority. Windows auto-calculates metrics based on link speed (e.g., Gigabit Ethernet gets a lower metric than Wi-Fi), but administrators can manually override via adapter properties > TCP/IPv4 > Advanced. The routing table (viewable with 'route print') shows the active default gateway. Why other options are wrong: Computer name identifies the machine on the network but does not affect routing. MAC address is a Layer 2 hardware identifier with no role in traffic prioritization. Display resolution is entirely unrelated to networking. Ref: Microsoft TCP/IP routing documentation.

Software Troubleshooting2 / 5

A user reports that their Android phone shows 'Insufficient Storage' even though they have only a few apps installed. What should the technician recommend checking FIRST?

AlexFull explanation from Alex

When an Android device reports 'Insufficient Storage' despite few installed apps, the most likely culprit is accumulated app cache and downloaded files. Browsers, social media, and messaging apps cache large amounts of temporary data. The technician should check Settings > Storage to identify space consumers, then clear cache (Settings > Apps > [App] > Storage > Clear Cache) and review the Downloads folder. Why other options are wrong: CPU speed affects performance, not storage capacity. Screen resolution settings consume negligible storage. Bluetooth version is a connectivity specification unrelated to storage. None of these hardware specs can cause storage exhaustion. Ref: Android developer documentation, Google Support.

Security3 / 5

A company's security policy requires that passwords must be at least 12 characters, include uppercase, lowercase, numbers, and special characters, and be changed every 90 days. Which security concept does this represent?

AlexFull explanation from Alex

The described policy—minimum 12 characters, mixed character types, 90-day rotation—exemplifies password complexity requirements. These are administrative security controls configured through Group Policy (secpol.msc) in Windows or directory services. CompTIA defines password complexity as enforcing minimum length, character diversity, expiration, history, and lockout thresholds. Why other options are wrong: Certificate-based authentication uses digital certificates (PKI), not passwords. Multi-factor authentication requires multiple verification methods (something you know, have, or are)—not password rules alone. Biometric policy governs fingerprint/facial recognition enrollment, not password composition. Ref: CompTIA A+ 220-1102 objectives, NIST SP 800-63B.

Operational Procedures4 / 5

A company wants to implement AI-based tools to assist their help desk. Which of the following is a VALID consideration when implementing AI in IT support?

AlexFull explanation from Alex

When implementing AI tools in IT support (chatbots, automated ticket routing, knowledge base search), organizations must evaluate accuracy, bias, and data privacy implications. AI models can produce incorrect responses (hallucinations), inherit biases from training data, and process sensitive information requiring regulatory compliance (GDPR, HIPAA). The CompTIA A+ 220-1102 objectives cover the purpose and limitations of AI/ML tools. Why other options are wrong: AI does not eliminate documentation needs—it requires maintained knowledge bases. AI cannot immediately replace all human staff; complex issues need human judgment. AI tools require significant configuration, training data, and ongoing tuning. Ref: CompTIA A+ 220-1102 objectives, NIST AI Risk Management Framework.

    Is clearing cache the same as clearing app storage?

  4. Alex · AI tutor

    No. Cache is temporary data; clearing app storage removes the app’s data.

About the COMPTIA-ACORE2 exam

Where can I take the COMPTIA-ACORE2 exam?

Pearson VUE testing center or online proctored (OnVUE).

How long is the CompTIA A+ Core 2 exam?

The CompTIA A+ Core 2 exam has 90 questions and a 90-minute time limit.

How do you pass CompTIA A+ Core 2?

Core 2 is the software half: operating systems and security are 28% each, so more than half the exam sits in those two domains alone. The catalog budget is around 80 hours. The common failure is treating it as a second hardware exam, because the questions are about Windows behaviour, permissions and procedure rather than components.

Should you take Core 1 or Core 2 first?

Either order works, because neither exam is a prerequisite for the other and CompTIA only issues A+ once both are passed. Most people sit Core 1 first because its hardware material is the easier entry point. If your background is help-desk software support, starting with Core 2 plays to what you already do.

Does A+ Core 2 expire?

The A+ certification is valid for three years from the pass date. You renew it through continuing education or by passing a higher-level CompTIA certification, which resets the clock without another A+ sitting.

What happens if you fail A+ Core 2?

You can rebook immediately for a second attempt. From the third attempt onwards there is a 14-day wait between tries, and CompTIA sets no maximum number of attempts.
