1. Select theINCORRECT statement regarding ESB connectors.

Integration is much faster than using sequences and proxy services.

Connectors cannot be directly added and removed to the runtime, so after deploying them you have to restart the servers.

No extensiveknowledge of the source system is required to use ESB connectors.

150+ connectors are available, and WS02 is continuously adding more to the connector collection.

2. Which statement is FALSE about inbound endpoints?

Inbound endpoints are useful when you have to configure the message sourcesdynamically.

Inbound endpoints can be clustered.

HTTP inbound endpoints can use existing default port 8280.

They always run based on the underlying task execution framework.

3. What is the most appropriate scenario for using a class mediator over a Script mediator?

For debugging purposes, you want to introduce some latency in the message flow.

You want to change just a single element in the XML payload without changing other elements.

For testing purposes, you want to record the elapsed time between calling a backend service and receiving the responseby the proxy service.

You want to develop a logging mediator that sends logging data to an external database such as MySQ

4. Which statement is FALSE with respect to secure vault?

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.

5. Which of the following EIP patterns does NOT alter the message content?

Wire-Tap

Message Translator

Content-Enricher

Splitter

6. Suppose youare writing a complex proxy service. In the middle of the task, you need to debug your proxy service as it is not working as expected. Select the mediator that can be used for debugging your proxy service.

Log mediator

Drop mediator

Validate mediator

Switch mediator

7. Which statement about the Entitlement mediator is true?

Entitlement mediator intercepts requests and evaluates the actions performed by the user against an extensible Access Control MarkupLanguage (XACML) policy.

All of the above.

When configuring the mediator, you specify which sequence to execute depending on the Entitlement mediator result.

Entitlement mediator can only work with WS02 Identity Server as the PolicyDecision Point.

8. Identify the INCORRECT statement regarding the <cacheld> in the <remoteInstance> configuration section of the <EI_HOME>/conf/registry.xml file.

<remoteInstanceurl="https://localhost:9443/registryn>

<id>instaceid</id>

<dbConfig>sha red registry </dbConfig>

< readonly >true</readOnly> <enableCache>true</enableCache> <registryRoot>/</registryRoot> <cacheldx/cacheld> </remoteInstance>

This cachelD is used to identify the cache it should look for when caching is enabled.

<cacheId> is the same as the JDBC connection URL of the registry database.

You can use any arbitrary name for the <cacheld> configuration element.

Both statement b and c are incorrect.

9. Select the best extension point of the ESB profile that can be used to secure an API created inside the ESB profile with access restricted to limited user roles.

Use an Axis2 handler

Write a custom Class mediator

Use an API handler

Use an Axis2 module

10. Which statement is FALSE about REST APIs in the ESB profile?

Specifying a url-template or a url-mapping is mandatory for all the resources in a REST AP

APIs can be exposed through HTTP inbound endpoints.

REST APIs are exposed over one of the HTTP listener ports opened by the EI http transport.

Each REST API can have multiple resources, and each resource can have different service orchestration logic of backend services.

11. How can users write their own connector for the ESB Profile of the WS02 EI?

Create a connector project and include proxy services to invoke the API provider's endpoints.

Create a connector project and write Synapse configurations that call the API provider's endpoints.

Create a connector project and use the API provider's SD

Both option a and b can be used.

12. Which message construct CANNOT directly receive messages from the protocol layer (wire)?

API

Inbound endpoint

Proxy service

Message processor

13. Consider the following scenario: in the next WS02 EI integration project, you need to implement the Content Filter enterprise integration pattern (EIP). However, the messages coming into your sequence are in awired format not supported in the ESB profile, so you cannot implement the Content Filter EIP.

What would be the best extension point that you can used to overcome this issue?

Write a Class mediator.

Write a Synapse handler.

Write a custom messagebuilder and formatter.

Use the Script mediator.

14. Which statement is FALSE about SSL profile support in WS02 EI?

SSL outbound profiles allow different SSL profiles for different backend servers.

Each ssl profile uses the same keystore and truststore.

Inbound SSL profiles allow you to specify different SSL profiles for different IPs of clients

The purpose of SSL profiles is to allow connections to different servers with different certificates and identities.

15. How do you configure a REST API to handle different mediation logic with different HTTP verbs?

Define a resource for each API, and only allow that HTTP verb for that particular resource.

Each HTTP method can be identified by the transport,and you can configure a sequence for each method at transport configuration logic.

Only define the message filtering switching logic inside a sequence, and each path can handle the specific HTTP verb.

Wrap a given REST API with an inbound so that youcan filter out requests based on an HTTP verb.

16. Which of the following is NOT an entry point or trigger of the Synapse mediation engine?

Outbound endpoints

Proxy services

APIs

Inbound endpoints

17. Which of the following is NOT an action to take in order to tune a new ESB profile server for high performance?

Synapse configuration level settings

JVM-level settings

WS02 Carbon platform level settings

OS-level settings

18. If you are running two or more ESB profile servers on the same physical machine, it is necessary to offset ports. Select the correct statement that describes how to offset ports in the ESB profile.

Go to <EI_HOME>/conf/axis2, open the axis2.xml file, and add the following top-level configuration: <Ports><Offset>2</Offsetx/Ports>

Both statement 1 and 2 are correct.

Both statement 1 and 2 are incorrect.

Go to <EI_HOME>/conf, open the carbon.xml file, locate the following configuration and increase the Offset ^ value. <Ports><Offset></Offsetx/Ports>

19. Which statement is FALSE about endpoints?

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.

20. Which statement is FALSE about error handling in the ESB profile?

If you do not define a fault sequence, in the case of an error in a sequence or a proxy service, an exception will be thrown and the message will be dropped.

In situationswhere a fault sequence is not specified explicitly, a default fault sequence will be used to handle errors.

Within the fault sequence, you can access error details using the ERROR_DETAIL property.

The Fault mediator can be used to customize error messages that are sent back to the client.

21. When building an integration scenario with the ESB profile, you CANNOT use:

JavaScript for processing messages at a given message sequence.

Synapse configuration language.

WS02 EItooling.

Java code to build the entire message processing logic.

22. What is the easiest method to put a thread sleep in the ESB profile for the purpose of troubleshooting and debugging?

Write a custom mediator and put a Java Thread.Sleep

Write a custom taskand put a Java Thread.Sleep

Write a Script mediator and use Java.lang.Thread.Sleep

Write a Class mediator and put a Thread.Sleep

23. Which statement is TRUE about Java Message Service (JMS) support in the ESB profile?

The ESB profile can be configured as both a JMS Producer and Consumer.

JMSsupports point-to-point communication models only.

The ESB profile can be configured as a shared topic listener.

Both statements a and c are correct.

24. Which statement is true about EIPs?

EIPs are designed to implement SO

EIPs are used by most ESB vendors as a common set of patterns related to integration.

EIP is a standard for all ESBs.

EIPs are not valid for modern integration scenarios.

25. Which statementabout the OAuth mediator is FALSE?

The client should obtain the OAuth access token from the authorization server and send it as an HTTP header in the resource request to the ESB profile.

Client has to register with the authorization server.

OAuth mediator can work with any authorization server to verify the OAuth access token.

OAuth mediator does the OAuth access token verification against an authorization server.
