Independent educational resource. This is not an official WGU or CompTIA exam and contains no recalled or proprietary test
questions. Confirm the exam code assigned in your WGU portal before studying.
Suggested use: Study the cram sheet, take the mock exam closed-book in 75 minutes, review every
rationale, then rebuild your weak-domain notes from memory.

, Final Cram Strategy
Core 1 questions reward disciplined selection, not random recall. Identify the environment, symptom, scope, constraints, and the
least invasive next step. A technically possible answer is not necessarily the best answer.
Six-step troubleshooting sequence
Step Action Exam behavior
1 Identify the problem Question user, inspect, reproduce, check changes, back up if needed
2 Establish a theory Start with obvious/common causes; consider multiple causes
3 Test the theory Confirm before replacing; if disproved, form a new theory or escalate
4 Plan and implement Assess impact, gain authorization, use least disruptive safe fix
5 Verify and prevent Test full functionality, user acceptance, preventive measures
6 Document Record findings, actions, outcomes, parts, and follow-up
Question language: FIRST = initial safe diagnostic action. BEST = satisfies every constraint. MOST LIKELY = strongest symptom
match. NEXT = follows logically from what has already been tested.
72-hour final review plan
When Task
T-72 to T-48 Rebuild ports, Wi-Fi bands, connectors, RAID, storage, printer process, cloud models.
T-48 to T-24 Complete mock exam timed. Categorize misses: knowledge, misread, reasoning, or speed.
T-24 to T-6 Review weak domains and explain each missed item aloud without notes.
Final 6 hours Light recall only; verify appointment requirements, rest, hydrate, and avoid new sources.

, Cram Sheet 1 - Mobile Devices
Topic Must know
Laptop RAM SODIMM; generation and platform compatibility matter. No POST/instability may be module or slot.
Laptop storage 2.5-inch SATA; M.2 SATA; M.2 NVMe/PCIe. M.2 is a form factor, not a guarantee of protocol.
Display Faint image = backlight/power; hinge-dependent image = cable; external display test separates panel path from
GPU/system.
Power USB-C Power Delivery depends on charger, cable, port, negotiated profile. Swollen battery = stop use and follow
safe disposal.
Wireless card Usually M.2 with delicate antenna leads; document lead positions.
Input Keyboards/touchpads often use ribbon/ZIF cables; digitizers support pen/touch.
Docking One connection may provide power, monitors, Ethernet, USB, and storage; capability varies by host/port.
Mobile radios and connections
• NFC: centimeters; tap-to-pay, tags, quick pairing.
• Bluetooth: short-range PAN; headsets, peripherals, tethering.
• Wi-Fi hotspot: shares cellular data over WLAN; USB/Bluetooth tethering are alternatives.
• GPS receives satellite timing/location; maps and assisted services may use data.
• Airplane mode disables radios rapidly; some platforms permit selective re-enable.
• MDM supports policy, inventory, configuration, app deployment, remote lock/wipe, and enterprise separation.
Mobile troubleshooting order
• Check airplane/radio state, range, account/service, credentials, saved profile, date/time, and updates.
• Determine scope: one app, one radio, one device, or all nearby devices.
• Forget/rejoin only after preserving required settings; reset all network settings later, not first.
• For liquid exposure: power off, disconnect, do not charge, follow vendor/service procedure.
