You are in the process of setting up an Ethernet network for a new building at your company's headquarters. You need to connect the wires from the different Ethernet office wall plates to your network rack. Which of the following components on the network rack should you use to connect the wires from the office wall plates?

Ethernet patch panel

You are assembling components in a network rack and need a device that connects three network segments. Which of the following devices will meet your networking needs?

Ethernet router Explanation An Ethernet router is a device that connects two or more network segments or subnets. This would meet your networking needs. An Ethernet switch lets you connect multiple devices to the same network segment, but does not connect the network segments. A wireless controller monitors and manages wireless access points in a wireless network architecture. An Ethernet patch panel provides an easy way to connect devices and accommodate different types of cabling, such as twisted-pair and fiber optic cables.

Drag each computer function on the left with its associated hardware component on the right. (Each option may be used more than once.) Hard disk Printer Keyboard CPU Speakers RAM DVD-RW Microphone

Hard disk Long-term storage Printer Output Keyboard Input CPU Processing Speakers Output RAM Processing DVD-RW Long-Term Storage Microphone Input Each computer hardware component performs a specific function. Input is defined as the movement of data or commands to the internal computer hardware. Input devices include: Mouse Keyboard Scanner Microphone Processing is defined as the flow of data through a series of procedures as defined by a set of instructions. Major processing components include: CPU (Central Processing Unit) RAM (random access memory). RAM is temporary, short-term storage used by the CPU to store processed information for quick access. RAM is considered volatile memory because it is not persistent. When the computer is turned off, all the data that was stored in RAM is lost. Long-term storage is defined as the act of saving or maintaining data. Long-term storage devices include: Hard disk drives Solid-state drives Optical drives (CD-ROM, DVD-ROM, and Blu-ray) Flash drives Output is defined as the process of a computer presenting, displaying, or otherwise giving data. Output devices include: Monitor Speaker Printer

Which of the following are considered computer hardware? (Select two.)

Printer & Motherboard

Which computer function takes data through a series of procedures as defined by a set of instructions?

Processing Explanation Processing is data flowing through a series of procedures as defined by a set of instructions. Storage is the act of saving or maintaining data. Output is the processes of presenting, displaying, or giving data. Networking is the practice of connecting two or more computers.

Which of the following are considered input devices? (Select three.)

Scanner Keyboard Microphone

You need to replace a broken monitor on a desktop system. You decide to replace it with a spare monitor that wasn't being used. Even though the monitor is made by a different manufacturer than the desktop computer, it still works with the computer. Which computer design concept makes this possible?

Standardization Standardization allows components from different manufacturers to be interchangeable. If a component meets the specified standards, it will work in the computer, regardless of manufacturer. Componentization means that a computer is a combination of several constituent parts that can be easily replaced by a field-replaceable unit (FRU). Firmware is a special type of software that has been embedded in the memory of a hardware component. Plug and play allows devices to work with computers without the need for additional configuration on the computer.

Your local area experiences brownouts or blackouts during frequent electrical storms. Which of the following components could you add to your network rack to help protect your servers from brownouts or blackouts?

UPS

The router below provides several ports for connecting two or more network segments or subnets. The port circled in red is a small form-factor pluggable (SFP) connector. Which type of network can connect to this port?

WAN Explanation A wide area network (WAN) is connected to the router using a small form-factor pluggable (SFP) connector. A local area network (LAN) is connected to the router using an RJ45 cable. A wireless network uses a wireless controller on the network rack to monitor and manages wireless access points. DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to automate the process of configuring devices on IP networks. It is not a type of network.
