Question 1 of 268

A network engineer is preparing for an office site survey with a height of 2.5 meters. Which three components are recommended to complete the survey? (Choose three.)

Answer choices
Show answer

Correct answers: A, B, F

When conducting an office site survey, it's essential to have certain components to ensure accuracy and efficiency. Using a battery pack to power APs is important for mobility and flexibility during the survey. A drawing of the office space is crucial as it allows for planning and documentation of AP and client placements. APs with built-in antennas are often preferred for their simplicity and ease of placement, which is practical for initial surveys. Using these components helps in creating an accurate site survey for optimal network performance.

Question 2 of 268

An engineer is designing a wireless network that will support many different types of wireless clients. When conducting the survey, which client must be used to ensure a consistent experience for all of the wireless clients?

Answer choices
Show answer

Correct answer: D

When designing a wireless network to support a wide range of clients, it is crucial to ensure that even the clients with the worst RF characteristics are able to connect and perform adequately. This approach ensures that all clients, regardless of their capabilities, can have a consistent and reliable network experience. Designing for the worst-performing client establishes a baseline that accommodates all other, more capable clients.

Question 3 of 268

An engineer has performed a predictive site survey for high-speed data and voice in an indoor office. What is the recommended data rate with גˆ’67 dBm signal level for optimal VoWLAN design?

Answer choices
Show answer

Correct answer: C

In designing a VoWLAN (Voice over WLAN) system, special considerations need to be taken to ensure optimal performance. The recommended data rate for voice or real-time application support typically starts at 12 Mbps, which balances reliable throughput with the need to minimize latency and jitter. The 24 Mbps data rate is generally more appropriate for real-time video applications rather than just voice. Therefore, for optimal VoWLAN design, 12 Mbps on 802.11 an provides a good balance as the lowest mandatory data rate while avoiding overcrowding and ensuring efficient use of the 5 GHz band which is less crowded than the 2.4 GHz band.

Question 4 of 268

A customer is concerned about mesh backhaul link security. Which level of encryption does the backhaul link use?

Answer choices
Show answer

Correct answer: B

The backhaul link uses AES (Advanced Encryption Standard) for encryption. AES is a widely adopted symmetric encryption algorithm known for its security and efficiency, making it an appropriate choice for securing wireless mesh backhaul links.

Question 5 of 268

As part of a wireless site survey in a hospital, an engineer needs to identify potential Layer 1 interferers. In which two areas is the engineer MOST likely to find sources of 2.4 GHz and 5 GHz RF noise? (Choose two.)

Answer choices
Show answer

Correct answers: B, E

In a hospital setting, two likely sources of 2.4 GHz and 5 GHz RF noise are kitchens and patient rooms. Kitchens often contain microwave ovens, which operate around 2.4 GHz and can cause significant interference with wireless networks. In patient rooms, various personal electronic devices such as mobile phones, tablets, and laptops frequently use the 2.4 GHz and 5 GHz frequencies for Wi-Fi and Bluetooth communication, contributing to RF noise in those bands. Other medical equipment like MRI machines, Gamma Knife radiation treatment, and X-ray radiography operate at frequencies outside the 2.4 GHz and 5 GHz range, making them less likely to be sources of interference.

Stories from the certified

As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.

Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.

Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.

Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
