Question 1 No single network technology is well-suited for all IoT applications. The reason(s) is/are: No network technology is widely available today No network technology has the combination of battery lifetime, communication range, and data rates for the wide range of IoT applications No network technology is inexpensive enough for IoT applications All of the above Question 2 Bluetooth Low Energy (BLE) has become popular for IoT applications because: It is widely available on Wi-Fi access points in homes, which can function as an IoT gateway It is widely available on popular smartphones It has low-enough power consumption to be used in many IoT devices Both B and C Question 3 Which of the following is not one of the "three Bs" of IoT resource constraints: Battery Bandwidth Business processes Bytes Question 4 Which of the following would use the most energy? A LTE radio transmitting for 1 minute An accelerometer sampling for 1 minute A WiFi radio transmitting for 1 minute A GPS receiver running for 1 minute Question 5 Which of the following was given as an example of noisy data in IoT: An FM radio station with static A GPS receiver showing a location in the middle of a house A camera sensor with a purple halo around bright objects Question 6 What is needed in order to accurately estimate the pose of an object? Nothing, the pose of an object can always be estimated One landmark and a range sensor or a bearing sensor Two landmarks and a range sensor or a bearing sensor More than two landmarks and a range sensor or a bearing sensor Question 7 Why is range measurement noise a challenge for localization with triangulation methods? It is not a challenge Because of flip ambiguities Because the sensors are not accurate enough Because it is hard to assign beacons to known positions Question 8 We have GPS. Why do we not use GPS for localization everywhere? GPS does not work indoors Outdoors, GPS does not work well in urban canyons There are applications that require higher localization precision than what we can get from GPS All of the above Question 9 The 2D curb-based localization algorithm localizes accurately a moving vehicle: On stretches of straight roads At intersections Off road All of the above
