An SOA solution designer has been asked to review a customer's service implementation.
The customer has implemented a stateful service which models an interaction with three consecutive steps. What is the best advice to give the customer?
Services should not be stateful.
Service components should ideally hold state in-memory to avoid unnecessary
State required by the service should be passed back and forth to the service consumer.
The interaction should be modeled as a BPEL process and deployed on IBM Process Server.
A company has a heterogeneous set of service-enabled and legacy applications deployed internally. Currently, user accounts are managed differently by each application and a user needs to authenticate using different user ID'S for different applications. This results in relatively high IT support and maintenance costs since the IT department must set up most of the application user accounts manually and there is a proliferation of extraneous user accounts across the IT systems. The company wants to address this issue by creating a unified user management system where the IT department can centrally manage users in the enterprise, including their credentials and roles.The solution should also automatically provision user accounts to various applications based on the user's role in the organization. Which of the following IBM SOA Foundation offerings is best suited to address these requirements?
IBM Tivoli Access Manager
IBM Tivoli Identity Manager
IBM Tivoli Provisioning Manager
IBM Tivoli Intelligent Orchestrator
A paper manufacturer has well defined business processes that are being implemented using SOA technology. As deployment proceeds, the team realizes that systems management at the resource level is not enabling performance measurement against business goals. The business sponsor asks the SOA solution designer to recommend a suitable remedy. Which of the following should the SOA solution designer recommend?
Schedule redevelopment of critical business service logic so that measurements could be automated. This would meet requirements without causing the project to miss their deployment deadline.
Deploy the SCA modules so that they are annotated with Common Base Events and
event logging. This would provide the measurements needed and cause relatively little delay.
Request a review of all service implementations against the objectives and goals that had been set by the business sponsor to ensure compliance.
Install IBM Tivoli Business Systems Manager product so that the operations team could provide a business view of process performance.
Following careful analysis, an organization has implemented a number of reusable services providing functionality which is useful to multiple lines of business. In order to facilitate reuse within the enterprise, what measures could the architect recommend?
Deploy services onto a federated systems management infrastructure and ensure that all projects wishing to reuse services provide systems management integration points.
Require business impact assessments of IT projects covering impact to other business
processes and applications.
Ensure that services are only accessible through a single, standard transport protocol.
Publish open-standards based service definitions in a repository freely accessible within the enterprise.
A retail company has recently launched a new service for business partners. The service has become much more popular than originally planned and is now performing poorly. The operations team asks the SOA solution designer for advice on how to resolve this problem. Which of the following should the SOA solution designer recommend?
Deploy the service to multiple WebSphere Process Servers and a workload distribution server be deployed to accommodate peak demand.
Review the service logic to diagnose the source of the poor performance and changes be
made to make the logic more efficient.
Modify the gateway servers in the network to govern the volume of service requests that
are received from business partners.
Split the service logic so the workload is handled by several new services according to
the tier structure of business partners.
To accommodate new requirements, a deployed, partner-facing service needs to be updated
without breaking existing service clients. Which two of the following WSDL changes can be incorporated in the service WSDL document yet maintaining a good chance at backwards- compatibility?
Changing the XML Schema type of a parameter in an operation.
Renaming an operation.
Adding a new XML schema type.
Changing the order of parameters in an operation. E. Adding a new operation.
A company has two varieties of customer self-help service. One is for premium customers,
and the other one is for all other customers. The premium service offers better performance and more options. Both services are used by a web application client that interfaces with the customer. Where is the best place to make the decision about which service should be invoked by the web application?
In the web application where it checks for premium status and invokes the appropriate service.
In the non-premium service, this is always invoked by the web application. This service checks on the status of the customer and forwards the request to the premium service if appropriate.
In a BPEL process called by the web application, which checks for premium status and sends the request to the appropriate service.
A SOA solution designer has been asked to review provisioning for business process management at an insurance company before deployment to agents in the field. Services have been implemented for deployment in several geographically distributed data centers. The SOA solution designer finds that services have been instrumented and Service Level Agreements (SLAs) have been defined, but no steps taken to ensure compliance. What action would best address this gap?
Establish regular operations conference calls to monitor actual service performance against the SLA targets and define corrective plans needed.
Define a representative small-scale deployment project to assess the performance of critical services against that projected by the business process model prior to refinement of
Introduce logic at each regional gateway server that compares actual service
performance against SLAs and raises operational alerts when appropriate.
