Study Notes

CompTIA A+ Certification Exam: Core 1 (Exam 220-1101)

Duplex printing reduces paper usage by printing on both sides.
DSL (Digital Subscriber Line) relies on POTS (Plain Old Telephone Service) lines; if POTS are down, internet access will be affected.
A sluggish PC with a constantly lit HDD light likely indicates that the hard drive (HDD) has no free space.
The 2.4GHz frequency effectively penetrates solid objects, while 5GHz offers faster data connections and has a higher bandwidth.
Virtual machine escape primarily concerns compromising the hypervisor, allowing unauthorized access to other virtual machines.
Verify the compatibility of the CPU socket and motherboard if pins do not align.
The MX record is stored in DNS (Domain Name System), which manages domain-to-IP address translations and email routing.
Upgrading RAM is crucial for improving performance when running multiple applications simultaneously.
Cat 6a is the minimum cable category capable of supporting a 10Gbps throughput.
ECC (Error-Correcting Code) RAM is recommended for VM hosts to prevent errors and crashes.
A defective inverter can cause a laptop's LCD panel to appear blank while still displaying a faint image under direct light.
Requesting a traffic exemption from the IT department is the best approach when a company's proxy blocks software updates.
DHCP should be configured on a router to enable internet connectivity for devices if they display a 169.254.x.x IP address.
Cool down the fuser by removing stuck paper before proceeding with repairs on a printer.
Charging cable issues in smartphones often result from foreign materials in the charge port.
M.2 NVMe SSDs provide the fastest data access for laptops, making them the best choice for performance enhancement.

A toner probe is useful for identifying unlabelled ports on a patch panel.
A 1TB NVMe SSD is the best recommendation for users needing fast storage.
The 802.11ac wireless standard supports both 5GHz and 2.4GHz channels.
802.11ax (Wi-Fi 6) offers the best range and throughput among wireless technologies.
Shielded Cat 6 cables are most cost-effective for mitigating electromagnetic interference (EMI) while sustaining performance.
Installing a PoE (Power over Ethernet) injector can quickly resolve power issues with IP phones connected to unmanaged switches.
The first step in RAM upgrades should be to verify the memory requirements of the motherboard.### RAM Upgrade and Compatibility
Verify the memory requirements of the motherboard before upgrading RAM to ensure compatibility.
Check the type, speed, and maximum capacity of RAM supported by the motherboard.

Connectivity Issues

Limited connectivity on a laptop may indicate a DHCP failure, which can be diagnosed using the ipconfig /all command.

Troubleshooting Fingerprint Scanners

Inquire about possible changes made to the scanner's environment or settings before taking further action.

Power Issues in Desktop Computers

Inspect the Molex connector when assessing suspected power issues with the motherboard, as it provides power to the motherboard and components.

Printer Issues

Streaking on printed pages could be due to a defective or dirty fuser, even if paper type and toner have been replaced.

Cloud Deployment Models

A private cloud deployment model offers complete control for managing company data, as it is managed solely by the organization.

Laser Printer Double Image

A maintenance kit issue due to a lack of installation can lead to double images on printouts, likely caused by the fuser.

Mobile Device Authentication

NFC (Near Field Communication) must be enabled on mobile devices to utilize 13.56MHz frequency short band authentication methods.

Troubleshooting Windows BSOD

A visual inspection of motherboard capacitors should be conducted if a desktop randomly shows BSOD or powers off unexpectedly.

Optimizing Wi-Fi Mesh Networks

A Wi-Fi analyzer can assist in identifying the best channel for performance improvement in a mesh network experiencing latency.

Mitigating Spam Emails

Enabling DMARC (Domain-based Message Authentication, Reporting and Conformance) would help mitigate the issue of spam emails that slip through filters.

GPS Failures in Mobile Phones

Loss of cellular service can cause the phone's GPS to malfunction, unlike older in-car GPS systems that operate independently.

Hard Drive Installation

M.2 is a form factor for SSDs allowing direct installation onto the motherboard without cables.

Uses of PaaS

PaaS (Platform as a Service) provides a platform suitable for application development, streamlining app creation without managing infrastructure.

Audio and Video Cables

HDMI cables are capable of carrying audio signals as well as video, unlike VGA, S-Video, and DVI which do not support audio.

Lightning Connector

The Lightning connector is a reversible connector introduced by Apple in 2012, replacing the older 30-pin connector.

Wi-Fi Coverage Issues

When users face bandwidth issues in a mesh network, checking for channel overcrowding using a Wi-Fi analyzer is essential for optimizing performance.

Cross-Platform Virtualization

Running Windows software on macOS can be achieved through cross-platform virtualization, enabling installation and execution of a Windows environment on a virtual machine.

Initial Troubleshooting Steps

Upon receiving an unspecified beep code and shutdown on startup, the next step should be verifying the header panel connector's connection to ensure power is supplied correctly.

Mobile Device Battery Drain

To minimize battery drain while using weather applications, configuring less frequent location checks in the app settings is advisable.

Mirrored Storage Requirements

RAID 1 setup utilizes two drives for mirrored storage, allowing redundancy with one drive failure, suitable for maintaining data.

Storage Area Network (SAN)

In server rooms, a SAN connects servers to high-speed storage devices dedicated to enhancing data access.

Investigating Workstation Boot Issues

If a hard drive diagnostics confirm functionality, the next step is to explore other potential causes for a workstation that is not booting, including BIOS settings and RAM.

Documenting Resolution Steps

Writing a knowledge base article on application errors and their resolutions is vital for future incident management and sharing solutions among technicians.### Hardware Issues and Troubleshooting
Beep codes from the onboard speaker indicate possible hardware problems, often related to overheating from an improperly installed processor fan.
If a projector fails to display images despite good signal output, testing the output resolution is critical as compatibility issues can prevent image display.
Dark blotches on a smartphone screen are likely due to digitizer damage rather than liquid or charging issues.

Networking Solutions

To avoid high latency in a SOHO wireless solution, configure all devices with different channels to prevent interference among access points.
A technician should use a patch panel to connect individual pairs of a Cat 6 cable, allowing for organized cable management when connecting to a switch.
Metered utilization in cloud computing means paying only for the resources used, encouraging efficient cost management.

Mobile and Device Management

Mobile Device Management (MDM) solutions can remotely wipe smartphone data and manage installed applications, meeting corporate security needs.
Users can increase total RAM through virtual memory without hardware upgrades, allowing the system to utilize hard disk space as additional RAM.

RAID and Storage Solutions

RAID 10 arrays combine striping and mirroring, providing redundancy and performance benefits, making them ideal for virtual machine hosts.
Before purchasing an NVMe drive, ensure the PC has both M.2 slots available and PCIe interfaces, as these factors are crucial for compatibility.

Audio and Video Equipment Issues

Connecting an HDMI-ARC port between a TV and a soundbar is critical for audio output; failing to do so may result in sound only coming from the TV speaker.

Problem Resolution Steps

When troubleshooting a suspected faulty power supply, the technician should establish a clear plan of action for resolution, including potential replacement procedures.

Connectivity Solutions

In cases where local internet connectivity fails, using a mobile hotspot can quickly establish an internet connection, bypassing issues with the ISP modem.
