Several new coverage cells are required to improve the Wi-Fi network of an organization. Which two standard designs are recommended? (Choose two.)
To improve the Wi-Fi network of an organization, two standard designs are recommended. First, using the 5GHz band provides increased network capacity with up to 23 nonoverlapping channels. This significantly reduces interference and maximizes throughput, making it more suitable for environments with multiple overlapping cells. Second, configuring cells that overlap one another to use nonoverlapping channels helps prevent co-channel interference, ensuring stable and efficient network performance. These two strategies are essential for optimizing Wi-Fi networks.
If I have understood correctly, C and E have somehow the same meaning: avoid signal overlapping, since E separate the channel to avoid using the same channel and having signal collision. See "Dynamic Channel Assignment" in https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-5/config-guide/b_cg85/radio_resource_management.html A and B are kind of tricky to mention 5GHz, which must have non-overlapping channels, and actually accomplish what C/E have done, but they're saying incorrect stuff. For A: 2.4GHz has 11 Channels, 5GHZ has 45 Channels For B: There are two types of APs: autonomous AP/controllerless AP/"Fat AP" and lightweight AP/AP with Controller. Ref:https://stormwindstudios.com/wireless-access-points/ And lightweight AP can be applied to 2.4GHz and 5Hz (there's command for both in cisco lightweight AP, just google it.... For D: I think the repeater cannot solve the problem of "overlapping channels" since it just re-transmit or "repeat" the signal, aka the overlapping channels will still be overlapping!
A-C the correct answers based on the ccna 200-301 official cert guide volume 1 page 627, they mentioned 5GHz channels briefly but clearly with figure 26-22 lists all 23 non-overlapping channels (36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,128,132,136,140,149,153,157,161). That's according to the official guide of the CCNA and I don't care about any other resources.
The correct answers are A and C. Although it is true that the 5Ghz band has more than 23 channels, depending on each country, it is understood that this option meets the minimum requirements of the question. Option E, as formulated, could lead to interference if the dynamically assigned channels match those used by neighboring access points, the best practice is usually careful channel planning to avoid interference and optimize performance. Dynamic channel assignment by the WLC may not be the optimal strategy in environments where interference with neighboring APs is sought to be avoided.
I though it is A and C but than i understood A is wrong. Because 5Ghz has 24 non-ovelapping channel. Some countries dont use all of them. Please be careful about it is differen channels and NON-overlapping channels. And i learned that Cisco WLCs (Wireless LAN Controllers) can be configured to dynamically set adjacent access points to the channel. This feature is called Dynamic Channel Assignment (DCA), and it helps to improve the overall performance of the wireless network by reducing co-channel interference.
C & E are correct https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/118833-wlc-design-ftrs-faq.html?dtid=osscdc000283
Correct answer AC
CE is correct Contact me for full questions <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="177a7663637e637e64577862637b78787c3974787a">[email protected]</a>
While A may be stating a fact, it is simply that - a statement, NOT an action. Meanwhile, C and E is actually about "configuring" and making changes to IMPROVE the network.
In Wi-Fi networking, the 5GHz band typically provides up to 24 nonoverlapping channels. However, the statement provided in option A mentioning 23 nonoverlapping channels is likely a typo or a slight variation from the standard understanding, but it still generally aligns with the concept of having numerous noninterfering channels in the 5GHz spectrum. So, the correct answers considering the options provided are: A. 5GHz provides increased network capacity with up to 23 nonoverlapping channels. C. Cells that overlap one another are configured to use nonoverlapping channels. Option A's mention of 23 channels is considered acceptable as it aligns with the intent of providing information about the 5GHz band's capability to support multiple nonoverlapping channels, despite the standard typically stating up to 24 channels.
Does anyone have a definitive answer to date? Please
Question A isn't a typo. so C and E is correct
AC should be correct
A. 5GHz provides increased network capacity with up to 23 nonoverlapping channels. The 5GHz band indeed offers more nonoverlapping channels compared to the 2.4GHz band, which helps in reducing interference and increasing network capacity. This allows for better performance in dense environments where many access points (APs) are deployed. C. Cells that overlap one another are configured to use nonoverlapping channels. When coverage cells overlap, it is crucial to configure them with nonoverlapping channels to minimize interference. This design principle helps in maintaining a stable and efficient Wi-Fi network by preventing co-channel interference, which can degrade performance. The other options are not recommended for standard Wi-Fi network designs:
AC are correct
because i think that A has a typo, 5GHz provides 24 nonoverapping channels not 23.
sorry, C & E are more correct
"For the 5 GHz radio, up to 23 non-overlapping channels are offered. Assigning a specific value statically assigns a channel to that AP." https://www.cisco.com/c/en/us/support/docs/smb/wireless/CB-Wireless-Mesh/2069-tz-Changing-RF-Channels.html#:~:text=For%20the%205%20GHz%20radio,including%20and%20surrounding%20that%20number.
A-C is correct.
E. Dynamically setting adjacent access points to the same channel is generally not recommended because it can lead to interference and reduced performance. Proper channel planning is more effective.
correct answer A and C
