Mobile Devices
Use this page to practise mobile devices questions. The A+ exam tests practical troubleshooting — connecting a symptom to the most likely cause and the safest fix without unnecessary data loss.
📅 Days 23–27🎯 ~43 questions/day⚖ 15% of exam- ✓Connection types: cellular (4G/5G), Wi-Fi, Bluetooth, NFC, USB, hotspot.
- ✓Mobile OS management: MDM, MAM, corporate vs personal data separation.
- ✓Common symptoms: battery drain, overheating, connectivity, slow performance.

Networking
Networking is 20% of CompTIA A+ Core 1 220-1101, covering TCP/IP ports and protocols, IP addressing and subnetting, wireless and wired standards, network services, and troubleshooting tools. The exam tests this through scenario questions asking you to identify a port, choose a cable or wireless standard, configure a client, or diagnose connectivity with the right command.
📅 Days 23–28🎯 ~36 questions/day⚖ 20% of exam- ✓Matching TCP and UDP ports to services such as SSH 22, DNS 53, HTTPS 443, RDP 3389
- ✓Distinguishing 802.11 wireless standards, frequencies, and 2.4 GHz versus 5 GHz channel behavior
- ✓Configuring IPv4 addressing, subnet masks, default gateways, DNS servers, and DHCP versus static assignment

Hardware
Hardware is 25% of CompTIA A+ Core 1 220-1101, covering laptop components, mobile device ports and accessories, RAM types, storage (HDD, SSD, flash), motherboards, CPUs, power supplies, and multifunction printers. Questions present real-world scenarios asking you to identify connectors, select compatible parts, interpret POST beep codes, or troubleshoot print defects and overheating issues.
📅 Days 23–28🎯 ~28 questions/day⚖ 25% of exam- ✓Match USB, Thunderbolt, Lightning, and RJ45 ports to laptop and mobile device functions
- ✓Differentiate DDR3, DDR4, DDR5, SODIMM, and ECC RAM by speed, voltage, and use case
- ✓Identify motherboard form factors (ATX, microATX, Mini-ITX) and header functions like front-panel connectors

Virtualization and Cloud Computing
Domain 4 of CompTIA A+ Core 1 220-1101 covers cloud service and deployment models, client-side virtualization, and the resource requirements that make virtual machines work. The exam tests these through scenario questions: matching IaaS, PaaS, and SaaS to a business need, picking public, private, hybrid, or community clouds, and identifying CPU virtualization extensions, RAM, and storage needs for hosted VMs.
📅 Days 23–25🎯 ~71 questions/day⚖ 11% of exam- ✓Distinguish IaaS, PaaS, and SaaS by which layer the provider manages versus the customer
- ✓Match public, private, hybrid, and community cloud models to given business scenarios
- ✓Identify client-side virtualization requirements: CPU virtualization extensions, RAM, and storage
