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.
