A technician needs to upgrade storage in a laptop. Which interface provides the FASTEST data transfer speeds?
Show answer & full rationale
A: M.2 SATA uses the NVMe form factor but is still limited to SATA III speeds (~550 MB/s).
B: SATA III tops out at ~550 MB/s — fast for SATA but far below NVMe speeds.
C: USB 3.0 maxes at 5 Gbps (~625 MB/s) and adds external latency, making it slower than internal NVMe.
D (Correct): M.2 NVMe PCIe Gen 4 delivers up to 7,000+ MB/s sequential read — the fastest commonly available laptop storage interface.
Which port does HTTP use by default?
Show answer & full rationale
A (Correct): HTTP (Hypertext Transfer Protocol) uses port 80 for unencrypted web traffic.
B: Port 443 is HTTPS (encrypted web traffic).
C: Port 21 is FTP control.
D: Port 8080 is a common alternative HTTP port used by proxies and development servers — not the default.
What is the PRIMARY function of a motherboard?
Show answer & full rationale
A (Correct): The motherboard is the main circuit board providing sockets, slots, and buses that interconnect the CPU, RAM, storage, expansion cards, and peripherals.
B: AC to DC conversion is the PSU's job.
C: The OS is stored on a storage drive — not the motherboard.
D: Network connectivity is provided by a NIC — not the motherboard directly.
What is virtualization?
Show answer & full rationale
A: Running separate OSes on separate hardware is just multiple machines — not virtualization.
B (Correct): Virtualization abstracts physical hardware resources (CPU, RAM, storage, network) and presents them to virtual machines, allowing multiple isolated environments on one host.
C: Data compression is a storage optimization — not virtualization.
D: Encryption is a security function — not virtualization.
What is the FIRST step in any professional troubleshooting process?
Show answer & full rationale
A: Restoring from backup is a recovery action, not the first troubleshooting step.
B: Replacing components without understanding the problem wastes time and money.
C: OS reinstallation is a last resort, not the first response.
D (Correct): Identifying the problem — gathering details from the user, observing symptoms, and duplicating the issue — is essential before any fix is attempted.
After identifying the problem, what is the NEXT step in the troubleshooting methodology?
Show answer & full rationale
A: Replacing all RAM is a drastic hardware action — not a methodical step.
B: Documentation is the final step after the solution is verified.
C: Implementing a solution before theorizing the cause may fix the wrong thing.
D (Correct): After identifying the problem, the next step is forming a theory about the probable cause based on symptoms, to guide targeted testing.
A Mac needs to reinstall macOS by downloading recovery tools from Apple servers. Which startup method is BEST?
Show answer & full rationale
A: Safe Mode is for troubleshooting an installed macOS, not reinstalling from Apple servers.
B: Macs use different firmware/recovery mechanisms than a "BIOS recovery partition."
C: Windows PE is for Windows systems.
D (Correct): Internet Recovery downloads recovery tools/installer from Apple servers.
A technician is asked to move a workstation from Windows 11 Home to Windows 11 Pro while keeping all applications, settings, and user data. Which method should be used?
Show answer & full rationale
A: Restoring another machine's image replaces the user's environment entirely and raises driver and licensing problems.
B: Reset with keep-nothing deliberately removes applications and data and does not change edition.
C (Correct): Home to Pro is a supported in-place edition upgrade; entering a Pro product key or purchasing through the Store unlocks the edition and preserves apps, settings, and data.
D: A clean install wipes the existing installation, losing applications and settings.
A technician needs to reduce malware risk from websites that try to exploit outdated browsers. Which is BEST?
Show answer & full rationale
A: Disabling the browser sandbox increases risk.
B: Turning off Windows Update increases vulnerability.
C (Correct): Keeping browsers updated and enabling built-in anti-phishing features reduces exposure to known web exploits.
D: Letting users bypass security warnings increases risk.
A user says they cannot access a website by name, but other sites work. The technician suspects a cached bad DNS entry. What should be done?
Show answer & full rationale
A (Correct): Flushing DNS clears cached entries and can resolve name resolution issues.
B: Formatting is destructive and unnecessary.
C: Monitor hardware is unrelated.
D: The firewall isn't the typical cause of DNS caching issues.
A ticketing system is enhanced so that AI automatically suggests a category and severity as the technician types the issue description. This BEST describes which concept?
Show answer & full rationale
A: Identity synchronization replicates user accounts between directories.
B: Data loss prevention inspects and blocks sensitive data from leaving the organization.
C (Correct): Embedding AI capability directly into an existing business application so it assists within the normal workflow is application integration.
D: Zero Trust is an access control model requiring continuous verification.
A technician needs to restore a single folder from a backup without overwriting newer files elsewhere. Which restore type is BEST?
Show answer & full rationale
A: A bare-metal restore overwrites the full system state.
B: Firmware rollback is unrelated.
C: Defragmentation is unrelated.
D (Correct): File-level restores allow selecting specific folders/files without restoring the whole system.
