(T/F) Multiple KPIs are aggregated to SLA
False
S1: In resource management, resource allocation is the allocation of a service provider’s resources to a customer
S2: Resource mapping is correspondence between resources required by the users and resources available with the provider
S1 is False and S2 is True
A third party application runs in the cloud for 12 hrs/day. At the end of one month[30 D], it was found that the cloud service suffered 5 outages of durations: 1h 30m, 30m, 2h 15m, 1h 45m and T h, each on different days over the service period. Suppose a cloud guarantees service availability for 97% of time. What are the possible values of T that SLA negotiation gets honored in terms of service availability.

Correct Statements regarding VM Load management
When load increases, new VMs should be scheduled to new nodes.
When load increases, use WOL to start up waiting nodes.
When load decreases, live migrate VMs to more utilized nodes.
Objectives of Resource Management
Improved Quality of Service(QoS)
Scalability
Increased throughput
Correct statements for necessary and sufficient conditions for the detection of inheritance conflict are:
Sufficient condition: current entry role is senior to at least one exit role.
Necessary condition: at least one exit role
Parts of the MapReduce is responsible for processing one or more chunks of data and producing the output results
Map task
(T/F) Consider that the peak computing demand for an organization is 200 units. The demand as a function of time can be expressed as D(t) = 3(1+t). Baseline (owned) unit cost is 120 and cloud unit cost is 125.
Cloud is costlier than owning for a period of 150 time units
True
