Disabling the 2.4GHz radios is the most cost-efficient way to increase network performance. The 2.4GHz frequency band is often crowded and subject to interference from neighboring networks and devices, which can negatively affect performance. By operating solely on the 5GHz band, which typically has less interference and congestion, the network performance can improve for devices that support 5GHz connectivity without incurring additional costs.
They do not want to increase the throughput to associated devices. So no channel bonding. Most COST effective solution is to disable 2.4ghz and use 5.0. Wifi is 802.11n which used 2.4 and 5.0. This has no cost to this solution.
channel bonding doesnt increase throughput
By enabling channel bonding, the office can increase the data rate of its WiFi network to 108 Mbps, which can provide a significant boost in performance.
How can it possibly not cost money to go from 2.4ghz to 5ghz?
Because 802.11n uses both 2.4 and 5.0. Disabling 2.4 will ensure only 5.0 is transmitting
however, you will have devices that are not compatible with 5ghz, so disabling 2.4ghz isnt the right play
In reality, sure you're right. But you have to answer these questions using CompTIA's logic.
Because WiFi 4 is dual band; it has both 2.4Ghz and 5Ghz frequency.
Channel bonding combines multiple channels—or lanes—to increase the amount of traffic that a modem's highway can comfortably support.
"Channel bonding is a networking technique that combines multiple communication channels or pathways to INCREASE the overall bandwidth and THROUGHPUT." "Channel bonding is employed in Wi-Fi networks to INCREASE the data THROUGHPUT for wireless devices" "Channel Bonding is a technique used in data communication that involves combining multiple network connections or channels into a single logical connection. This results in INCREASED network THROUGHPUT" Ok, now that THAT'S done, the question very explicitly states "neighboring offices DO NOT want to INCREASE the THROUGHPUT..." The answer CANNOT be C.
The 2.4GHz frequency band is often crowded and subject to interference from neighboring networks and devices, which can negatively impact network performance. By disabling the 2.4GHz radios and focusing solely on the 5GHz frequency band, the network can potentially experience better performance and reduced interference, which aligns with the goal of increasing network performance in a cost-efficient manner. Enabling channel bonding (option C) can indeed be a valid consideration to increase network performance. Channel bonding involves combining multiple adjacent channels in the 2.4GHz or 5GHz frequency bands to increase the available bandwidth, which can lead to improved data rates and throughput. Enabling channel bonding can be a cost-efficient way to enhance network performance, especially if the neighboring offices do not object to increased throughput. However, it's worth noting that while channel bonding can provide benefits, it might also introduce higher potential for interference in congested environments, particularly if not managed properly.
Keywords : " do not want to increase the throughput" Channel bonding increases throughput. With that being said, disabling the 2.4ghz will increase performance as they will all use 5ghz instead
Ok, so I think this is more about the "NEIGBORING OFFICES" portion. I don't disagree with the channel bonding assessment, but this feels like either CompTIA is throwing in a red herring, or they are pointing you towards an answer with this detail. So I am gonna say B. Disabling 2.4Ghz. This is more of a listening to test writers prompting the correct direction than it is base level factual knowledge. So good luck everyone, hope this isn't on our test cause it looks like BS
We dont have to do anything with neighboring offices. statement "neigboring offices do not want to increase their throughput" means they dont want to do anything to their existing setup. Read question without caring for neighboring offices and choose best answer to increase your small office wifi performance. wifi 4 has 2.4 & 5 spectrums but enabling channel bonding will increase performance.
The most cost-efficient way for a small office running WiFi 4 Access Points (APs) to increase network performance, without increasing the throughput to associated devices, is: C. Enable channel bonding Channel bonding allows two channels within the same frequency band to be combined to increase throughput and network performance. This can be a cost-effective solution because it doesn’t require purchasing new hardware and can be configured on existing APs
B. Disable the 2.4GHz radios. Disabling the 2.4GHz radios would likely be the most cost-efficient solution because it does not involve purchasing new hardware or upgrading existing infrastructure. By disabling the 2.4GHz radios, the network would operate solely on the 5GHz band, which typically experiences less interference and congestion compared to the 2.4GHz band. This could potentially improve network performance for devices that support 5GHz connectivity without incurring additional costs.
To assist with the issue and prevent any interruption in the neighboring offices, removing the 2.4GHz lanes are the best option. It will take care of both points mentioned.
B for sure
The most cost-efficient way to increase network performance in this scenario would likely be: C. Enable channel bonding. Channel bonding involves combining multiple adjacent channels into a single, wider channel. This can increase the overall data transfer rate and improve network performance. It's a more cost-effective option compared to adding another AP or upgrading to WiFi 5, as enabling channel bonding can be done through configuration changes on the existing equipment.
Wireless N supports the use of multiple-input-multiple-output (MIMO) technology to use multiple antennas to transmit and receive data at higher speeds. Wireless N supports channel bonding by combining two 20 MHz channels into a single 40 MHz channel to provide additional bandwidth.
NIC teaming Two or more NIC aggregated into a single channel link for fault tolerance and increased throughput. Also known as NIC bonding
Channel bonding is a wireless networking technique that combines channels to increase bandwidth.
While channel bonding can increase throughput, it may also increase interference for neighboring offices and is not as cost-effective as simply upgrading to WiFi 5. Upgrading to WiFi 5 is a cost-effective way to improve network performance within the existing infrastructure, benefiting from the enhancements and efficiencies of the newer standard. However, it's important to ensure that client devices are compatible with WiFi 5 for the best results.
Answer: C is correct. Going back to the Core 1 book: "The 802.11n standard allows two adjacent 20 MHz channels to be combined into a single 40 MHz channel, referred to as “channel bonding.” Due to the restricted channel layout of 2.4 GHz, on a network with multiple APs, channel bonding is a practical option only in the 5 GHz band.". So in short, the best answer is channel bonding which would require you to change your channel to 5ghz regardless. This would give you increased reliability.
