This set of IOT Multiple Choice Questions & Answers (MCQs) focuses on “Cloud – Runtime Adaption Engine”.
1. QoE stands for _________
a) Quality of Energy
b) Quality of Experience
c) Quality of Envelop
d) Quality of Encryption
View Answer
Explanation: If the light weight query engine returns a poor result, then the user may have to issue my query redundantly to the cloud based query processing engine with the hope of getting a better result. This may hurt the overall Quality of Experience.

Explanation: OAD (Optimal Application Distribution) proposes a formal framework which allows to explore the possibility space of optimally distributing application components across cloud offerings in an efficient and flexible manner.
7. _________ enables the application developer to enhance the application design.
a) Cloud Blueprint
b) TOSCA standard
c) Both Cloud blueprint and TOSCA standard
d) Utility function
View Answer
Explanation: TOSCA standard and Cloud Blueprint enable the application developer to enhance the application design by providing the means to model which cloud offering is used to host which parts of the application stack.
8. _________ process must support the analysis and evaluation of the application topology.
a) Support of different Migration types
b) Enrichment of Topology specification
c) Management and Configuration
d) Top-down and bottom-up
View Answer
Explanation: Top-down and bottom-up application evaluation process must support the analysis and evaluation of the application topology alternatives both based on previous knowledge and empirical analysis, and during the application productive phase.
9. _________ process has to support the definition of application topologies in various formats.
a) Top-down and bottom-up
b) Enrichment of Topology specification
c) Management and Configuration
d) Support of different Migration types
View Answer
Explanation: Enrichment of Topology specification process has to support the definition of application topologies in various formats such as TOSCA or Blueprints and must consider non-functional aspects specified as extension of the previous formats.
10. Any tool providing _________ process must provide management and configuration for cloud services.
a) Top-down and bottom-up
b) Enrichment of Topology specification
c) Management and Configuration
d) Support of different Migration types
View Answer
Explanation: Any tool providing Management and Configuration process must provide management and configuration for cloud services from different providers covering all cloud service and delivery models.

a) Top-down and bottom-up
b) Enrichment of Topology specification
c) Management and Configuration
d) Support of different Migration types
View Answer
Explanation: In order to re- distribute an application support of different migration types process has to support all cloud native and non cloud native application types identified.
