Exam OG0-023 topic 2 question 4 discussion

Scenario -
Please read this scenario prior to answering the question
The ArchiSuranceTo Go mobile consumer solution is increasingly important to ArchiSurance, which uses it to sell and renew insurance products, provide customer service, enable accurate and convenient home recordkeeping, and capture and process claims. The solution consists of three components. The
Consultant lets customers review their existing coverage, and update it based on common life events, such as getting a new car, moving into a new home, or having a family member move in or out. If necessary, they can speak or chat with a customer service representative. The Home Manager helps customers photograph and catalogue their valuable possessions in order to support the filing of accurate claims in case of loss or damage. The Claim Manager enables customers to quickly file a claim for loss or damage to an insured auto, home or possession. It enables customers to describe the incident by referencing information captured with the Consultant and the Home Manager applications. In addition, it allows the customer to add photographs, audio, video and text to support a claim, submit the claim, and monitor its progress.
The ArchiSurancetoGo components rely on a number of application services hosted by ArchiSurance. The first is an Auto Identification and Description (AID) service that the Consultant uses to validate and complete auto information entered by customers. The second service, Home Identification and Description (HID) performs the same function for home information, and is used by the Home Manager. The Consultant also uses the Virtual Agent service to guide customers as they select coverage options, the Payment Processor service to arrange premium payments, and the Coverage Activator service to generate policies and put them in force.
ArchiSurance to Go also relies on a number of infrastructure services. The Home Manager uses a Multimedia Repository service to store and retrieve information about insured homes. The Claim Manager also uses this service for claim information entered by customers. All three components of ArchiSuranceTo Go use a
Personal Security service to register and authenticate customers, and to manage their profiles.
Each application service is realized by an application component with the same name. Also, each infrastructure service is realized by a system software environment with the same name. ArchiSurance hosts both the application components and system software environments in a virtual ized server pool within its data center. Each service has its own virtual server. Each server is connected to a data center network (DCN) which in turn connects to a commercial wide area network (WAN).
