• Question 83:

  An organization is categorizing their existing services against service characteristics to determine how ready each one might be for the catalog. Part of this effort involves looking at the following three attributes for each service characteristic: considerations, benefits, and tradeoffs.

  What attributes correspond to the following characteristics: Reusable and Composable?

  A. Consideration: service usually has to be agnostic to context Tradeoff: complexity grows as number of services increases
  B. Consideration: late or dynamic binding of services Benefit: requires collaborative service design
  C. Benefit: can be human readable metadata Tradeoff: improved recovery from failure
  D. Benefit: improves reliability and scale TradeOff: high degree of cooperation and agreement of design standards and conventions
  A. Consideration: service usually has to be agnostic to context Tradeoff: complexity grows as number of services increases

• Question 84:

  A company has an IT organization that is separated into teams that support different underlying technologies. Each team has its own budget and manages its own tools. They have a clear understanding of current performance, capacity, and

  events. Team response to assigned help desk tickets is satisfactory.

• Question 87:

  An IT organization has hired you as a cloud architect to assist them in planning for cloud services. Your first goal is to help the IT organization categorize existing services against service characteristics. You have provided a table that shows common service characteristics and their attributes for considerations, benefits, and trade-offs.

  The following attributes from the table have been identified: -Consideration standardized service contracts and metadata definitions -Benefit: development and implementation cost reduction -Tradeoff: very finite capability

  What characteristics correspond to the identified attributes?

  A. Loosely Coupled, Composable, and Autonomy
  B. Discoverable, Reusable, and Autonomy
  C. Idempotent, Composable, and Discoverable
  D. Idempotent, Loosely Coupled, and Reusable
  A. Loosely Coupled, Composable, and Autonomy

• Question 88:

  Which chargeback model best fits this scenario?

  A. Fixed cost and guaranteed resources with threshold limits for usage
  B. Both guaranteed and variable resources allowing for overuse
  C. Variable resources that allows flexibility for LOBs, with threshold limits for usage
  D. Pay-as-you-use capability that allows IT to maximize utilization of resources.
  D. Pay-as-you-use capability that allows IT to maximize utilization of resources.
