Fill in the blank.

You are watching: Which network device regenerates the data signal without segmenting the network?

broadband technology uses different frequencies to transmit multiple signals simultaneously over the same cable.

Answers Explanation & Hints:

Broadband technology uses different frequencies, divided into different channels, to allow simultaneous transmission of multiple different signals on the same cable. DSL, cable, and satellite are examples of broadband network connections.

A switch is a networking device that will record MAC addresses by inspecting every incoming data frame.

Answers Explanation & Hints:

A switch will maintain a switching table that contains a list of available MAC addresses on the network, The switching table will record MAC addresses by inspecting the source MAC address of every incoming frame.

Which type of network will extend a short distance and connects printers, mice, and keyboards to an individual host?

PANLANMANWLAN
Answers Explanation & Hints:

A personal area network (PAN) connects devices, such as mice, keyboards, printers, smartphones, and tablets. These devices are often connected with Bluetooth technology. Bluetooth allows devices to communicate over short distances.

A technician has captured packets on a network that has been running slowly when accessing the internet. Which port number should the technician look for within the captured material to locate HTTP packets?

20215311080
Answers Explanation & Hints:

HTTP uses TCP port 80 and HTTPS uses TCP port 443. HTTP and HTTPS are protocols commonly used to access web pages.

Which three Wi-Fi standards operate in the 2.4GHz range of frequencies? (Choose three.)

802.11n802.11ac802.11g802.11a802.11b
Answers Explanation & Hints:

802.11b and 802.11g operate in the 2.4GHz range, and 802.11n can operate in either the 2.4GHz or the 5GHz range. 802.11a and 802.11ac operate only in the 5GHz range of frequencies.

What are two common media used in networks? (Choose two.)

coppernylonwaterfiberwood
Answers Explanation & Hints:

Common media used in networks include copper, glass or plastic optical fiber, and wireless.

Which network device regenerates the data signal without segmenting the network?

routermodemswitchhub
Answers Explanation & Hints:

Hubs are sometimes called repeaters because they regenerate the signal. All devices connected to the hub share the same bandwidth (unlike a switch, which gives each device dedicated bandwidth).

Which smart home technology requires the use of a device, known as a coordinator, to create a wireless PAN?

802.11ac802.11nZigbeeZ-Wave
Answers Explanation & Hints:

The ZigBee Coordinator is a device that manages all the ZigBee client devices to create a ZigBee wireless personal-area network (PAN) using the 868 MHz to 2.4 GHz range.

Which security technology is used to passively monitor network traffic with the objective of detecting a possible attack?

IPSIDSproxy serverfirewall
Answers Explanation & Hints:

An IDS system is implemented to passively monitor the traffic on a network. Both an IPS and a firewall actively monitor network traffic and take immediate actions when previously defined security criteria match. A proxy server, when it functions as a firewall, also actively monitors the traffic that travels through it and takes immediate actions.

A company is expanding its business to other countries. All branch offices must remain connected to corporate headquarters at all times. Which network technology is required to support this scenario?

LANMANWANWLAN
Answers Explanation & Hints:

A WAN connects multiple LANs that are in geographically separated locations. A MAN connects multiple LANs in a large campus or in a city. WLAN is a wireless LAN that covers a rather small geographic area.

Fill in the blank.

The technology that allows a switch to deliver power to a device like an IP phone or an access point through the data cable is known as PoE .

Which technology uses existing electrical wiring to connect devices to a network?

IPS802.11Z-WaveEthernet over Power
Answers Explanation & Hints:

Ethernet over Power, or powerline networking, uses a device that attaches to a power outlet and a cable to connect a device to a network. IEEE 802.11 is a standard for wireless networks. An intrusion prevention system (IPS) is a security device that monitors all inbound and outbound traffic. Z-Wave is a type of network used in a smart home.

Which two protocols operate at the transport layer of the TCP/IP model? (Choose two.)

UDPICMPTCPFTPIP
Answers Explanation & Hints:

The TCP/IP model includes four layers. The application layer, the transport layer, the internet layer, and the network access layer. The functions at each layer include different protocols. The transport layer includes both the TCP and the UDP protocols.

Which network service automatically assigns IP addresses to devices on the network?

tracerouteDNSDHCPTelnet
Answers Explanation & Hints:

Dynamic Host Configuration Protocol (DHCP) can be used to allow end devices to automatically configure IP information, such as their IP address, subnet mask, DNS server, and default gateway. The DNS service is used to provide domain name resolution, mapping hostnames to IP addresses. Telnet is a method for remotely accessing a CLI session of a switch or router. Traceroute is a command used to determine the path a packet takes as it traverses the network.
