Exam 200-301 topic 1 question 872 discussion

Should be "C". 802.11g uses 2.4GHz and throughput up to 54 Mbit/s. “enhanced SSID security” = hiding SSID, so we must uncheck Broadcast SSID option

Stupid Cisco question and stupid Cisco answer. Synonym game instead of testing real networking skills. Hiding SSID is not some high tech, and it does not make it safe at all. Many free mobile apps can be used to detect the hidden SSIDs. WiFi security can be achieved by regularly changing passwords, enforcing strong passwords, employing certificate based authentication, and upgrading to WPA3 etc.

"""enhanced SSID security""" is disable broadcast SSID, 300IQ move

it´s C

it must be C

C. Uncheck the Broadcast SSID check box and set the Radio Policy to 802.11g only. (enhanced SSID security) ( must operate at 2.4 Ghz)

Based on Cisco's article, disabling SSID broadcast provides some security, so answer C should be correct. "This article guides you on how to successfully disable SSID broadcast on your access point for added security" https://www.cisco.com/c/en/us/support/docs/smb/wireless/cisco-small-business-100-series-wireless-access-points/smb5177-disable-ssid-broadcast-on-a-wireless-access-point.html

both 802.1a/g have a maximum data rate of 54Mbps, unfortunately only 802.1g provides for 2.4, 802.1a provides for 5Ghz

Option C is correct:(Answer from ChatGPT) Unchecking the Broadcast SSID check box will hide the network name (SSID) from being broadcasted to wireless clients. Setting the Radio Policy to 802.11g only will allow the network to operate at 2.4 GHz with 54 Mbps of throughput. Option A is incorrect because setting the Radio Policy to 802.11a/g only will enable both 2.4 GHz and 5 GHz bands, which may not be necessary for the requirements given. Option B is incorrect because checking the Broadcast SSID check box will broadcast the network name, which could potentially make it easier for attackers to target the network. Option D is incorrect because setting the Radio Policy to 802.11a only will disable the 2.4 GHz band, which is required for the requirements given.

as hiding your SSID does not provide complete security, and other methods such as encryption and a strong password should also be used1. In practice, hiding the SSID makes no difference whatsoever to the security of your network2. Therefore, it is recommended that you do not hide your SSID also any hacker with a simple network sniffing tool can find out your SSID in seconds, even if you are not broadcasting it.

802.11a operating frequency is 5GHz - it is not correct answer

The answer is C

For me, the correct answer is the b. https://it.wikipedia.org/wiki/IEEE_802.11 It uses the same frequencies as the 802.11b standard i.e. the 2.4 GHz band and provides a theoretical speed of 54 Mb/s which in reality translates into a net speed of 24.7 Mb/s, similar to that of the 802.11a standard .

802.11a is 5 Ghz and we want 2.4 only ("must" operate at 2.4) so A is incorrect.
