TIBCO Architecting Composite Applications and Services with TIBCO Set 1

1.

Which statement best characterizes the IT architecture for a solution?

It defines the set of products, technologies, programming tools, and coding standards to be used to implement a solution. It is a compilation of user features required for the solution. It defines the structure of a solution (communication mechanisms, components) suitable for the present purpose. It provides a generic framework, such as an application server, that is suitable for solving any common business problem.

2.

When wrapping a backend system, what does a Web Service always provide that the native system interface does not?

standardized service operation semantics an HTTP-based interface a common data model access independent of implementation technology

3.

What is the Recovery Point Objective (RPO) of a system?

a formal contract detailing the critical systems to be restored the point in time to which the application state must be restored the complete collection of data that must be restored the time period that can elapse before normal operation must be restored

4.

Which activity is appropriate for implementation as a synchronous request-reply operation?

processing a request that requires human action performing a long-running update to a backend system keeping a cache of customer information continuously updated retrieving data from a backend system

5.

What is the recommended TIBCO best practice for handling major version changes to interfaces?

The service version should be identified in the SOAP body. Interface definitions should contain "Any" elements as general purpose extension areas. New major versions should be treated as new services. All components must be upgraded to always use the latest version.

6.

Which type of wiring can be done at deployment time?

from a reference in one SCA composite to a service of another SCA composite from a service in one SCA composite to a reference of another SCA composite from a component reference to a component service in the same SCA composite from a component service to a component reference in the same SCA composite

7.

When is it appropriate to use a Mediation implementation type?

when the interaction with an underlying service is asynchronous when each underlying service operation completes quickly when service operation might need human interaction when the underlying service is a REST service

8.

How do you achieve high availability for a TIBCO ActiveMatrix Spring component providing a service with a JMS binding type?

deploy the service in the system node so the ActiveMatrix infrastructure can manage availability deploy the service across multiple nodes; TIBCO Enterprise Message Service delivers requests to the next available service instance create a single node that spans multiple hosts to provide resiliency in the event of host failure specify virtualization upon service deployment allowing ActiveMatrix to transparently recover a failed service

9.

A manufacturer exposes a Web Service to its customers, allowing them to securely place orders. The manufacturer requires that only known parties use the interface. How is the customer's identity established?

by implementing a transactional policy set in ActiveMatrix by specifying an authentication policy for the Web Service by sending the message over an SSL-encrypted channel by implementing strict authorization rules for the service

10.

How do you achieve high availability for a TIBCO ActiveMatrix Java component providing a service with a SOAP/HTTP binding type?

specify virtualization upon service deployment allowing ActiveMatrix to transparently route requests deploy the service in the system node so the ActiveMatrix infrastructure can manage availability deploy the service across multiple nodes and place a load balancer in front of the service instances create a single node that spans multiple hosts to provide resiliency in the event of host failure
