When looking up secured passwords in a Synapse configuration, it is possible to use theXPath expression ,,wso2:vault-lookup('alias,) to retrieve the actual password by providing 'alias'.

Secure vault can be used to secure plain text passwords stored in ESB profile configuration files.

Secure vault uses the cipher-tool.properties filesto identify the locations of the passwords in configuration U files.

Secure vault always uses the certificate in the primary keystore configured in carbon.xml to encrypt the passwords.

This happens when a soapll message is sent to a soapl2 endpoint or vice versa, resulting in the p, message content type not matching the SOAP namespace URI, e.g., soapll should have text/xml content type and soapl2 should

have application/soap+xml content type. Solution: Enable the relevant message builder/formatter in axis2.xml for the matching content type.

The ESB profile has failed to extract the transport protocol from the given URL. This happens when theO transport defined in the URL is not enabled in the system. Solution: Enable relevant transport sender in axis2.xml.

This happens when a soapll message is sent to a soapl2 endpoint or vice versa. Solution: Correct the SOAP envelope namespace.

Options a, b and c all provide mismatching reasons/solutions, so all of the answers are incorrect.

Use an Axis2 handler

Write a custom Class mediator

Use an API handler

Use an Axis2 module

Create a separate endpoints CAR file for each environment (Dev, QA, Prod) and deploy the endpoints CAR and the ESB profile configurations CAR file.

All of the above approaches can be used for externalizing endpoints.

Parameterize the endpoints values and replace those with matching endpoint values at build time using a Maven project.

Externalize and store the endpoints in the registry and refer to them by name in the ESB profile configuration.

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.

A proxy service receives messages that aresent to specific endpoint.

APIs can only accept JSON or XML messages but not SOAP messages.

An inbound endpoint injects a message directly from the transport layer to the mediation layer, without going through the Axis engine.

A task injects a message into the ESB profile at a scheduled interval.

Use the XSLT mediator with the Validate mediator and send the message out with a default enpoint.

Implement message transformation with the Data Mapper and use endpoint format as soapll.

Use the XSLT mediator and use the Call mediator with blocking mode.

Use the XSLT mediator and use the Call mediator with blocking mode with enable addressing.
