JNCIA-DC: Juniper Networks Certified Associate – Data Center — Question 14
You are troubleshooting a signal strength issue when you notice that the signal strength changes from -70 to -73 dBm as you move from one room to another.
In this scenario, what is happening?
Answer options
- A. Signal strength has increased by 10x.
- B. Signal strength has decreased by 10x.
- C. Signal strength has doubled.
- D. Signal strength has halved.
Correct answer: B
Explanation
The correct answer is B, as a decrease from -70 dBm to -73 dBm indicates a weaker signal. This change represents a reduction in power, which in logarithmic terms is approximately a 10-fold decrease in signal strength. The other options incorrectly interpret the change in dBm values.
