Please read this scenario prior to answering the question
An airline operates a Flight Scheduling process supported by a Scheduling Engine and Crew Management application.
Flight schedules and staff availability are stored in separate databases. Both applications run in redundant server clusters connected via dual LAN switches and independent storage arrays.
Refer to the scenario.
Which option best represents the relationships across layers?

• A. Model Flight Scheduling as a Business Process served by Application Services realized by Application Functions assigned to Application Components, accessing Data Objects, deployed on Server Nodes connected through Communication Networks to Storage Devices.
• B. Model crew availability as a Business Actor.
• C. Use Aggregation only for all relationships.
• D. Model applications only as Technology Nodes.

The IT Operations (IT Ops) department at ArchiSurance has five core responsibilities, each encompassing a dedicated business process: (1) Batch Operations (Batch Ops), (2) Online Operations (Online Ops), (3) Security Operations (Security Ops), (4) User Support and (5) Continuous Improvement. Service level agreements (SLAs) are in place for Batch Ops and Online Ops, and each Ops process generates monitoring data that is utilized by the Continuous Improvement process.
The System Ops category consists of Batch Ops, Online Ops, and Security Ops, each having an incident management sub-process. These sub-processes are triggered by Batch, Online, and Security Incidents, respectively. In the initial stages of the incident management sub-processes, an Incident Alert is shared with the System Ops processes by posting it to the Alert Buffer.
Batch Ops relies on a schedule that outlines all batch jobs and their dependencies. This schedule serves two sub-processes: Batch Planning, which updates the schedule for use by the Execution Management sub-process.
The Batch Ops process relies on a suite of interconnected applications to facilitate its operations.
Among these applications, the Batch Scheduler plays a vital role by allowing users to manage a comprehensive database of jobs, job schedules, and dependencies. It effectively launches batch jobs according to the information stored in the database.
Working in conjunction with the Batch Scheduler, the Batch Monitor application utilizes the job schedules as a reference point to monitor job execution. It identifies any exceptional conditions that may arise during the execution process. To ensure effective handling of these exceptions, the Batch Monitor communicates the information to both the Batch Scheduler and the Incident Handler applications through the previously mentioned Alert Buffer.
The Incident Handler application operates based on a defined set of business rules. It uses these rules to determine the relevant systems and individuals that need to be notified in the event of each incident. Subsequently, the Incident Handler application generates appropriate notifications according to these determinations.
Recognizing the criticality of the Batch Scheduler, Batch Monitor, and Incident Handler applications, ArchiSurance has implemented redundant hosting arrangements across multiple geographically distributed data centers. In each data center, these three applications are supported by fully redundant virtual server clusters. Each cluster is connected to two site local area networks, both of which are further linked to separate storage array hardware devices.
Refer to the scenario
As part of an IT service management initiative, you have been assigned the task to show how applications and technology support the Batch Ops process. This should show the relationships between the applications, their functions, the data they access, and the technology that hosts the applications and data, along with the networks that connect the servers. It is only necessary to model a single data center.
