1.5-1.6 Flashcards
A tech configures a network to use an E-lines service. Compare and evaluate the choices to determine which network type the tech configures.
WAN
CAN
PAN
MAN
MAN
A metropolitan area network (MAN) is a network that covers an area equivalent to a municipality. A MAN uses a service category such as an E-line, which establishes a point-to-point link or an E-LAN, which establishes a mesh topology.
A tech configures three computers in an office so users can share files. Which type of network does the tech create?
MAN
CAN
WAN
PAN
PAN
A personal area network (PAN) is a network that connects two to three devices with cables and is most often seen in small or home offices.
A building offers extremely poor wireless connectivity and IT support staff routinely deal with user complaints. The lead IT engineer plans to reposition all access points (AP) for better coverage. Of the given choices, which can immediately improve wireless connectivity?
Extended SSID (ESSID) Dynamic rate switching (DRS) Site survey Heat map
Dynamic rate switching (DRS)
Each station can determine an appropriate data rate based on the quality of a signal using Dynamic Rate Switching/Selection (DRS). Currently, the data rate can be automatically adjusted, maintaining functionality.
To increase wireless bandwidth in a large building, an engineer researches solutions. Which of the following implementations refers to using 40 MHz as a solution?
MU-MIMO
Channel bonding
Omnidirectional antenna
Unidirectional antenna
Channel bonding
802.11n can obtain more bandwidth with the option to use two adjacent 20 MHz channels as a single 40 MHz channel, referred to as channel bonding.
A consumer configures a new wireless router at home and only configures the 5 GHz band. Which wireless standard only works with this band?
n
ac
b
g
ac
The 802.11ac standard continues the development of 802.11n technologies. The main distinction is that 802.11ac works only in the 5 GHz band.
A Jr. systems administrator at an organization has just learned to use a multiple input multiple output (MIMO) configuration with a 802.11n wireless network. The administrator now plans on increasing bandwith by adding the maximum number of antennas possible in a 4x4:2 configuration. After evaluating the administrator’s approach, which option defines the planned implementation?
The number of transmit antennas x the number of receive antennas : the number of channels bonded
The number of recieve antennas x the number of transmit antennas : the number of channels bonded
The number of transmit antennas x the number of receive antennas : the number of simultaneous transmit and receive streams
The number of receive antennas x the number of transmit antennas : the number of simultaneous transmit and receive streams
The number of transmit antennas x the number of receive antennas : the number of simultaneous transmit and receive streams
Multiple Input Multiple Output (MIMO) is the use of multiple antennas to boost bandwidth and is identified by AxB:C notation. A is the number of transmit antennas, B is the number of receive antennas, and C is the number of simultaneous transmit and receive streams.
A tech configures a yagi for a wireless network. Which component does the tech configure?
MIMO
Unidirectional antenna
MU-MIMO
Omnidirectional antenna
Unidirectional antenna
A unidirectional antenna type includes the Yagi (a bar with fins) and parabolic (dish or grid) form factors. Unidirectional antennas are useful for point-to-point connections (a wireless bridge).
