  4. JBI

  5. SCA

Reveal answer Fill a bubble to check yourself
A,B,C Correct answer
Explanation

JBoss ESB supports SOAP for web services, JEE for enterprise Java integration, and UDDI for service registry and discovery. These standards form the core interoperability framework of the ESB. JBI (Java Business Integration) and SCA (Service Component Architecture) are separate integration specifications not primarily supported by JBoss ESB.

Multiple choice general knowledge science & technology
  1. Apache Ant

  2. Apache Maven

  3. Hudson

  4. IVY

  5. Continuum

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mule ESB supports Apache Maven out of the box through Mule Maven plugins and archetypes, making it easy to build, package, and deploy Mule applications. Maven is the standard build tool for Mule projects. Apache Ant is supported but not the primary out-of-the-box mechanism. Hudson, IVY, and Continuum are not Mule's core build tools.

Multiple choice general knowledge science & technology
  1. A Java Library wrapping with Hibernate a Database schema

  2. A graph based language represent some kind of execution which can be shown as a graph.

  3. A workflow engine

  4. All of the above

  5. None

Reveal answer Fill a bubble to check yourself
D Correct answer

  4. All of the above

  5. None of these

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Drools is a business rule management system and rule engine that separates business logic from application code. While often used alongside jBPM, Drools itself focuses specifically on rule execution, not workflow orchestration or BPEL.

Multiple choice general knowledge science & technology

  2. 7.0

  3. 7.0 Beta 2

  4. 7.0.1

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

NetBeans 7.0 Beta 2 was a cutting-edge version when this question was written (around 2008-2009). This version introduced significant improvements including better PHP support, improved editor features, and enhanced performance. NetBeans has evolved significantly since then and is now in version 15+, but for its time, Beta 2 was indeed the latest.

Multiple choice technology programming languages
  1. Data Readers

  2. Performance Counters

  3. Web Performance Counters

  4. Data Performance Counters

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In .NET, Performance Counters are the standard mechanism for obtaining performance information about web applications. They provide metrics on CPU usage, memory consumption, request rates, response times, and other performance indicators for monitoring and diagnostics.

Multiple choice technology programming languages
  1. The Session object.

  2. The Application object.

  3. The Response object

  4. The Server object

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Application object stores data that is shared across all users and sessions of an ASP.NET application, making it ideal for maintaining global state. In contrast, the Session object is user-specific, while Response and Server objects handle HTTP responses and server utilities respectively and are not designed for data storage across users.

Multiple choice technology embedded technologies
  1. MIDP 2.0

  2. MIDP2.1

  3. MIDP 1.0

  4. CLDC1.1

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

JTWI (Java Technology for the Wireless Industry) specification mandates MIDP 2.0 as the minimum requirement for compliant devices. While JTWI also requires CLDC 1.1 (option D), the core profile requirement is MIDP 2.0, making option A correct. MIDP 2.1 is a later version not required by the original JTWI standard.
