Exam 300-425 topic 1 question 15 discussion

D is the correct one. https://support.ekahau.com/hc/en-us/articles/115004974107-Configuring-Active-Surveys

Answer D - "When you perform an ACTIVE site survey to validate the network’s performance, packet loss or the packet error rate (PER) should be no greater than about 1 percent." Cisco Press Book ENWLSD - Ch5 Applying Wireless Design Requirements - You don't get performance results with a Passive Site Survey, it helps you to discover what its in the wireless network but not the performance of it.

The best way to validate network performance based on the provided alternatives

D is correct for end to end

The question said "Type of Survey" and "Passive" is the only type survey available between the answers

D is correct

Source: https://support.ekahau.com/hc/en-us/articles/115004974107-Configuring-Active-Surveys The end-to-end network performance testing (Ping) is always made with the wireless network adapter that is currently associated with the network.

Clearly D.

D has to be correct, ping is the only way to test end to end. Spectrum will only indicate issues on the RF portion of the link.

Active Ping Surveys The end-to-end network performance testing (Ping) is always made with the wireless network adapter that is currently associated with the network. Typically it is the laptop's integrated Wi-Fi network adapter, but you may also use external adapter such as an 802.11ac adapter. Before you start the survey, make sure wireless network adapter is connected to the Wi-Fi network to be able to measure the network performance. So D.

"To collect active survey data, you must have an external network adapter collecting passive survey data in addition to the internal NIC for active survey data. For example, Ekahau Sidekick or SA-1 adapter in passive mode in addition to the internal NIC in throughput mode." Active ping is not used by the engineer but done by the Wireless network adapter. An external analyzer, like SA, should be in Passive Mode for this to happen. Tricky question but the given answer is correct.

Correct answer is D

Spectrum Analysis and Passive Surveys are typically pre-installation surveys (or troubleshooting) Active ping is a way of active survey. Active survey is a post-installation survey. In my opinion the answer must be D

Ekahau utilizes spectrum analyzer to perform end-to end wireless and non wireless issues affecting the network. Provided answer is correct.

Answer: C

I think it must be D
