Question 1 of 358

Which electrical characteristic is displayed with the correct preferred value?

Answer choices
Show answer

Correct answer: B

Dielectric strength should have a high value, as it represents the material's ability to withstand electric stress without breaking down. A high dielectric strength means the material can handle higher voltages, which is desirable.

Question 2 of 358

Assume that the optical power transmitted by a 62.5/125 multimode fiber is distributed uniformly across its core. If this fiber is perfectly coupled (i.e., the two fibers are aligned and abutted) to a 50/125 fiber, what is the percent of power that is lost?

Answer choices
Show answer

Correct answer: B

When a 62.5/125 multimode fiber is perfectly coupled to a 50/125 multimode fiber, there will be a power loss due to the difference in core sizes. The core area of the 62.5/125 fiber is larger than that of the 50/125 fiber. Specifically, the cross-sectional area of the 62.5/125 fiber core is (π * (62.5/2)^2) and the cross-sectional area of the 50/125 fiber core is (π * (50/2)^2). The ratio of these two areas gives the fraction of the power that is coupled from the 62.5/125 fiber to the 50/125 fiber. This ratio is (50/62.5)^2, which equals 0.64. This means that 64 percent of the power from the 62.5/125 fiber is successfully coupled into the 50/125 fiber, indicating a 36 percent power loss.

Question 3 of 358

On a project with three small conference rooms, a break room, and twelve private offices, what is the MINIMUM number of telecommunications outlet boxes required?

Answer choices
Show answer

Correct answer: C

For each of the twelve private offices, a minimum of two telecommunications outlet boxes is required, totaling 24 outlets. For each of the three small conference rooms, at least one outlet box is needed for each room, adding 3 outlets. The break room requires at least one outlet box. Therefore, the minimum number of telecommunications outlet boxes required is 28.

Question 4 of 358

In the ceiling zone method of distribution, the usable floor area should be divided into zones each measuring:

Answer choices
Show answer

Correct answer: C

In the ceiling zone method of distribution, the usable floor area is typically divided into zones that measure between 23 square meters (250 square feet) and 84 square meters (904 square feet). This range ensures efficient use of space and allows for manageable zone sizes in terms of access and connectivity.

Question 5 of 358

On a survey of one of your client's buildings, you discover that one of the TRs, housing a considerable quantity of switching equipment, is at 25 degrees C (77 degrees F) with a relative humidity of 59 percent. This is considered to be:

Answer choices
Show answer

Correct answer: C

The temperature of 25 degrees C (77 degrees F) falls within the accepted range for normal operating conditions, typically considered to be between 18-27 degrees C (64-81 degrees F). However, a relative humidity of 59 percent is towards the higher end of the acceptable range, which generally should not exceed 55 percent. Therefore, the conditions described are normal for temperature but slightly high for humidity.

Stories from the certified

Charles Sirois
Canada
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.
Lance Chambers
United States
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.
Alisha Kelly
Italy
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.
Casper Claassen
Netherlands
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.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.
Remi Nuyts
