WS02 EI can support TLS 1, TLS 1.1, and TLS 1.2 with JDK 1.7

You must enable HTTPS transport configuration in aixs2.xml in order to usetransport-level security.

The HTTPS transport supports SSL tunneling.

Transport-level security secures the messages in the wire.

Endpoints are used to define external destinations of a message.

The same endpoint cannot be used with multiple transports.

An endpoint can be defined independently of transports.

Once configurations are defined, the endpoint can be used to connect to any external service.

When retry count is 0.

When thesuspend timeout is reached.

When there is a response from the endpoint.

When the retry count is a positive integer.

All of the above are correct.

Throttling isonly supported at the mediation level.

The throttle mechanism is used to control access to the services at different levels.

Mediation level throttling works in distributed fashion only when ESB nodes are configured as a stateful cluster which is a membership based cluster.

Use of class variables is not recommended.

You can define and use a global variable in the mediator class if and only if those variables are shared with all the messages in that particular message flow.

When we use the mediatorin different artifacts, an instance of the mediator gets created for each occurrence in the configuration.

A mediator instance gets created for each occurrence in the configuration and for each message.

For all endpoint timeout values. Endpoint Timeout >= http.socket.timeout

The following is a correct endpoint definition with a timeout value and a response action:

url="http://localhost:8281/services/SimpleStockQuoteService" >

120000

fault

</address>

It is possible to define a responseAction to be taken in case of an endpoint timeout within the endpoint definition.

Endpoint timeout specifies the timeout duration for an endpoint and allows different timeouts to be specified for different endpoint definitions.

Write a Script mediator.

Write a custom mediator.

Write an Axis2 handler.

Write a custom message builder and formatter.

Every connector is self-contained and independent of ESB code.

A connector is a ready-made convenient tool to reach publicly available web APIs.

Hardcoding usernames and passwords in the connector configuration is required to connect to externa public APIs that require authentication.

Connectors provide dynamic tooling support with EI tooling.
