Study Notes

RJ45 Connectors and Tools

A crimper is essential for attaching RJ45 connectors securely to patch cables.
A cable tester checks the functionality of a network cable but does not help with connector attachment.
A punchdown tool is used for terminating network cables in panels, not for patch cables.
A loopback plug tests network interfaces by simulating data traffic.

VLANs and Network Segmentation

Virtual LANs (VLANs) segment a single switch into multiple logical networks.
VLANs create multiple broadcast domains, enhancing network performance and security.
They allow isolation of departments, applications, or users from one another.

Corporate Smartphone Connectivity Issues

A smartphone without a SIM card cannot connect to cellular networks, losing cloud service access off-site.
Mobile Device Management (MDM) is not essential for basic connectivity.
Other common issues (S/MIME certificate corruption, Bluetooth errors) are less likely in this context.

Hot-Swappable Components and RAM Replacement

Always verify that the operating system supports hot-swapping before replacing RAM in servers.
Hot-swappable RAM allows replacement without turning off the server, but OS compatibility is crucial.

Data Access After Hardware Upgrade

To access data on an encrypted hard drive after replacing the motherboard, enable the TPM in BIOS.
The Trusted Platform Module (TPM) is required for accessing encrypted keys.

Wireless Technologies

802.11ax (Wi-Fi 6) has the best range and throughput among wireless technologies listed, surpassing 802.11ac and older standards.

Laser Printer Issues

Vertical streaks in laser printer output are usually caused by a damaged or worn-out photosensitive drum rather than other components.
To resolve ghost images on printed pages of a laser printer, the first action should be to clean the toner drums and rollers.

Security Features Against Unauthorized Booting

Enable Secure Boot to prevent systems from booting unauthorized media like live Linux CDs.
Secure Boot verifies the digital signature of bootloaders, ensuring only trusted software runs at startup.

Impact Printer Maintenance

Impact printers utilize ribbons for printing; faded output might indicate the ribbon needs replacement.
Common impact printers include dot matrix printers, which rely on ribbons for image production.

Cloud Models and Data Retention

A hybrid cloud model combines on-site data with cloud storage, providing flexibility and improved security based on organizational needs.
Public clouds do not support on-site data retention as they store all data managed by third-party providers.
