220-1101 Question 50
Single answerRecognizing data capsA technician is troubleshooting repeated reports that a remote employee's video meetings become choppy near the end of each month. The employee uses a mobile hotspot as the primary internet connection while traveling. Signal strength is excellent, the hotspot reboots successfully, and speed tests are fast at the start of the billing cycle but much slower after several weeks of use. Which issue is the technician MOST likely identifying?
- A
The hotspot is reaching the ISP's monthly data cap or high-speed allotment, causing throttled speeds
- B
The wireless adapter is switching from 5 GHz to 2.4 GHz, which blocks video conferencing traffic
- C
The employee's laptop battery health is degrading, which reduces network throughput over time
- D
The mobile hotspot is overheating only at the end of the month because of calendar-based firmware tasks
Show answer and explanation
Correct answer: A
Explanation
The best answer is the mobile plan's data cap or high-speed data allotment being exceeded. In real-world troubleshooting, a strong signal combined with degraded performance later in the billing period is a classic sign of ISP throttling after a usage threshold has been reached. This is especially common with cellular hotspots and metered mobile broadband plans. A technician should verify monthly usage in the carrier account or hotspot management portal, review the plan details for reduced-speed thresholds, and discuss options such as upgrading the plan, reducing high-bandwidth activities, scheduling large downloads on unmetered connections, or enabling metered-connection settings on client devices. This aligns with common vendor and carrier documentation describing monthly data allowances and reduced speeds after the limit is reached.
- A. Correct.
Correct. This scenario strongly suggests a data cap or reduced-speed threshold on a cellular or hotspot plan. Many mobile broadband plans include a monthly high-speed data allowance. After that allowance is consumed, the provider may throttle throughput, which can make video meetings unstable even when signal strength remains strong.
- B. Incorrect.
Incorrect. A band change from 5 GHz to 2.4 GHz can affect performance due to interference or lower throughput, but it would not typically line up with the end of each billing cycle. Also, changing Wi-Fi bands does not specifically block video conferencing traffic.
- C. Incorrect.
Incorrect. Poor battery health can affect portability or power settings, but it does not normally create a predictable monthly pattern tied to internet speed tests. This distractor reflects a hardware-focused troubleshooting mistake when the evidence points to a service-plan limitation.
- D. Incorrect.
Incorrect. Overheating can reduce performance, but there is no realistic reason it would occur specifically near the end of every month because of calendar timing. The repeatable pattern tied to usage over the billing cycle is the key clue that points to a data cap.
