The component on the switch that tells you it can be mounted to a rack is rack ears.

If you're shopping for a rack switch, what component on the switch tells you it can be mounted to a rack?

What are some elements that are typically included in network diagrams?

Some elements that are included in a network diagram are the physical layout, logical topology, IP address reserves, names of major network devices, and types of transmission media.

routers, switches, and the KVM switch

Which of the following devices are you likely to find in the MDF? Choose all that apply.

Entrance Facility

A technician from your ISP has arrived to help you troubleshoot a weak WAN connection. To what location do you take them?

A transceiver was recently damaged by a lightning strike during a storm. How might you decide whether the ISP is responsible for replacing this device, or whether your company must foot the bill.

Why is it important to minimize cable clutter in a rack?

It's important to minimize cable clutter because it allows easier access to the rack, reduces likelihood of overheating, and maximizes performance.

How can you go about gathering the information needed to assemble a thorough operations manual?

Look in data rooms for computer information, checking computer systems and workstations, checking receipts for equipment and software, and using a protocol analyzer or network management software package.

In a large organization, how do you typically request permission to perform a network change?

Submit a change request form, follow the approval process, have the project managed, provide additional documentation, and finish the change.
