This set of IOT Multiple Choice Questions & Answers (MCQs) focuses on “API Based Architecture”.
1. API enables services portability between ____________
Explanation: API enables services portability between sysyems, I.e., service may be allocated to end-systems or servers, with possible relocation and replication throughout its lifecycle.
2. Ubiquitous service provision depends on _________
Explanation: Ubiquitous service provision depends on interoperability, not only for provisioning of a standard QoS controlled IP bearer, but also for cross domain naming, security, mobility, multicast, including fair compensation for utility provisioning.
3. API architecture not only includes critical elements but also caters for _________
d) Multi homing
Explanation: API architecture not only includes critical elements but also caters for multi homing, mobile networks with dynamic membership, and third party persistent storage based on indirection.
4. All portals are embedded into a single supercomputer, known as _________
Explanation: The web is now one, enormous, global computer. Our devices are them phones, tablets, TVS, watches, glasses, etc. These all are all portals into this single computer, known as Web.
5. _________ is uniquely identifiable embedded computing devices.
Explanation: The IoT is the part of the Internet that is made up of “uniquely identified embedded computing devices,” as Wikipedia status. Just like the world Wide Web is a Internet, so does the IoT.
6. Web is a mesh of computers, so too is _________
Explanation: Just like the World Wide Web runs over the Internet, so does the IoT. Similarly to how the Web is a mesh of computers, so too is the IoT.
7. Without _________ computers embedded in house keys are worthless.
c) Both Data and Services
d) Neither data nor services
Explanation: Without data and services, the little computers embedded in thermostat, house keys, baby monitors, trash cans, fire extinguishers, and store shelve are nearly worthless.
8. _________ Services are the way in which the IoT is connected to data.
Explanation: Cloud based services are the way in which the IoT is connected to data. Just like World Wide Web runs over the Internet, so does the IoT.
9. APIs are the skybridge.
Explanation: APIs are the skybridge – IoT on one side, useful information and plentiful data crunching capabilities on the other. APIs make IoT useful, turning limited little things into powerful portals of possibilities.
10. IoT solutions are at the heart of IDC’s view of the _________
Explanation: IoT solutions are at the heart of IDC’s view of the four pillars:
Resulting in the millions of applications available to the billions at the end point.
11. _________ are the inter connectors.
Explanation: APIs are the inter connector which provides the interface between the Internet and Things.
12. Is APIs are glue?
Explanation: JavaWorld’s Andrew Oliver calls APIs “the glue and interesting part where the Internet of Things starts to become useful and more than a buzzword.”
13. Most IoT problems are addressed at _________ layer
Explanation: As more and more devices are connected to the net, however, certain recurring problems must be solved. These problems are addressed at the API layer.
14. IoT-A stands for ________
a) Internet of Things Address
b) Internet of Things Architecture
c) Internet of Things Area
d) Industrial of things Architecture
Explanation: The EU’s Internet of Things Architecture is another example of the way in which we can solve IoT related challenges.
15. IoT-A reference model is a _________
c) Both scalable and secure
d) Neither scalable nor secure
Explanation: IoT-A architectural reference model is a scalable and secure solution intended to guide the design of protocols, interface and algorithms necessary to scale the IoT.
