A company is deploying a new wireless network and requires 800Mbps network throughput.
Which of the following is the MINIMUM configuration that would meet this need? used. With MIMO, multiple antennas are used for transmission and reception. MIMO was available in 802.11nbut its capabilities have been extended in 802.11ac. minimum bandwidth of 800Mbps. Two antennas and 80 MHz channel bandwidth provides a bandwidth of

A network technician has been tasked with designing a WLAN for a small office. One of the requirements of this design is that it is capable of supporting HD video streaming to multiple devices.
Which of the following would be the appropriate wireless technology for this design? therefore need the fastest wireless network speed available. band.

A user with a 802.11n WLAN card is connected to a SOHO network and is only able to connect at 11 Mbps with full signal strength.
Which of the following standards is implemented on the network? speeds up to 300Mbps, the user is only able to connect at 11Mbps because the user is connected to a wireless network configured to use 802.11b.

The management team wants to set up a wireless network in their office but all of their phones operate at the2.4 GHz frequency. They need a wireless network that would be able to operate at a higher frequency than their phones.
Which of following standards should be used?

Which of the following devices implements CSMA/CA virtually through the RTS/CTS protocols? where computers connected to the wireless network attempt to avoid collisions by transmitting data only when the channel is sensed to be “idle”. Carrier Sense Multiple Access/Collision Detect (CSMA/CD) is unreliable in wireless networks because computers connected to the wireless network often cannot see each other so goes some way to alleviating the problem of computers not being able to see each other because in a wireless network, the Wireless Access Point only issues a “Clear to Send” to one node at a time.

Which of the following will negotiate standoff timers to allow multiple devices to communicate on congested network segments? transmitting data on the network. and therefore available for the transmission of data. The network device then transmits a data frame onto the network. If another device sends a frame at exactly the same time, a collision occurs and the frames are discarded. The network devices will then wait for a random period of time before attempting to send the frame again.

A network administrator is using a packet analyzer to determine an issue on the local LAN. Two separate computers are showing an error message on the screen and are unable to communicate with other computers in the same lab. The network administrator looks at the following output:
SRC MAC SRC IP DST MAC DST IP
00:1D:1F:AB:10:7D 192.168.1.10:2000 15:BE:9F:AB:10:1D 192.168.1.14:120005:DD:1F:AB:10:27 192.168.1.10:1000 22:C7:2F:AB:10:A2 192.168.1.15:1300
Given that all the computers in the lab are directly connected to the same switch, and are not using any virtualization technology, at which of the following layers of the OSI model is the problem occurring? has a unique MAC address. These are the network cards in the two separate computers. that “An IP conflict exists”. Every network card connected to the network needs to be configured with a different occurring at the Network layer (layer 3) of the OSI model. The network layer is responsible for Internet Protocol

When troubleshooting a network problem, browsing through the log of a switch, it is discovered that multiple frames contain errors.
In which of the following layers does the problem reside? (Select TWO). component in the data-link layer is a network switch.

A network engineer is dispatched to an employee office to troubleshoot an issue with the employee’s laptop.
The employee is unable to connect to local and remote resources. The network engineer flips the laptop’s wireless switch on to resolve the issue.
At which of the following layers of the OSI model was the issue resolved? was unable to connect to the wireless network because the wireless network interface card was switched off. wireless network interface card is a physical layer device.

When a client calls and describes a problem with a computer not being able to reach the Internet, in which of the following places of the OSI model would a technician begin troubleshooting? cabling, the network card etc. In other words, the computer’s physical connection to the network.
