100-150 Question 128
Single answerA small business network consists of IoT devices (smart thermostats and cameras), computers, mobile devices, IP phones, printers, and a server. Employees report that their IP phones frequently lose connectivity during video streams from the IoT cameras. What is the most likely cause of this issue?
- A
Insufficient bandwidth allocation for critical devices like IP phones
- B
Malfunctioning IoT cameras causing network congestion
- C
Incorrect IP configuration on the server
- D
Printer firmware not being updated
Show answer and explanation
Correct answer: A
Explanation
The problem described is likely a result of insufficient bandwidth allocation for critical devices like IP phones. IoT cameras are bandwidth-intensive, and without proper network configuration (such as implementing Quality of Service), they can consume excessive bandwidth, leading to connectivity issues for other devices. Configuring QoS to prioritize IP phone traffic would resolve this issue.
- A. Correct.
IP phones losing connectivity during video streams suggests that insufficient bandwidth allocation for critical devices like IP phones is the most likely cause. Bandwidth-intensive devices like IoT cameras can overwhelm the network without proper Quality of Service (QoS) settings.
- B. Incorrect.
While malfunctioning IoT cameras could cause some network issues, this is less likely to specifically affect IP phones during video streams. The issue is more related to bandwidth management.
- C. Incorrect.
Incorrect IP configuration on the server would not typically cause intermittent connectivity issues for IP phones during IoT camera video streams.
- D. Incorrect.
Printer firmware not being updated would not cause any impact on IP phone connectivity or video streams from IoT cameras.
