What are the building blocks of a Service Component Architecture?

  1. Service Components

  2. Adapters

  3. Webservices

  4. None
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Service Components are the fundamental building blocks of Service Component Architecture (SCA). These are the actual business logic components like BPEL processes, mediators, business rules, and other service implementations. Adapters (option B) are used for connectivity, web services (option C) are a binding type, and SCA is specifically built around composable service components.

The primary means by which the business users access PeopleSoft applications is -

  1. Web server

  2. Application server

  3. Web browser

  4. Java servelets
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

PeopleSoft applications run on a pure internet architecture where client-side interactions are completely web-based. Business users interact with the system entirely through a standard web browser, which communicates with the backend web and application servers rather than using dedicated client software.

Multiple choice technology enterprise content management

Define the publishing type -Forcefully overwrites the existing published objects and their properties/attributes.

  1. Full refresh

  2. Incremental refresh

  3. Force refresh

  4. Single object publish
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Full refresh publishing completely replaces all existing published objects and their attributes, ensuring a clean slate. This approach is ideal when you want to ensure complete synchronization between source and target systems. Incremental refresh only updates modified items, while Single object publish targets individual elements.

Multiple choice technology platforms and products

_______ is the Android way of doing IPC that is interface based and lightweight

  1. Android Interface Description Language

  2. Android Inter-process Description Language

  3. Android Definition Language

  4. None of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

AIDL (Android Interface Definition Language) is Android's interface-based IPC mechanism that defines the programming interface that both the client and service agree upon. It enables communication between processes with method calls similar to local Java interfaces.

Multiple choice technology architecture

____ minimizes an application's footprint with in Server development environment.Options

  1. Classpath Repair Plug-in

  2. Browser Virtualization

  3. Minimal J2EE Desktop Cloud

  4. Minimal Server
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A Minimal Server configuration reduces the application's resource footprint by only including essential components needed for development and testing, rather than deploying a full server environment. This approach is particularly useful in development scenarios where you want to conserve system resources while still maintaining core server functionality.

Multiple choice technology architecture

RUN FROM ____ is an automation scheme that simplifies the configuration of a server to point at a local java project in eclipse

  1. Destination

  2. Source

  3. ClassPath

  4. Dependency Jar
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

RUN FROM SOURCE is an automation feature that simplifies server configuration to point at a local Java project in Eclipse. This allows developers to quickly test and deploy their code from the Eclipse workspace without manual server setup.

Multiple choice technology architecture

Name the initiative of SDIS which allow developers to use multiple browsers to test their applications

  1. Minimal server

  2. Minimal J2EE desktop cloud

  3. Browser Virtualization

  4. Classpath repair plug-in
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Browser Virtualization is the SDIS initiative that enables developers to test applications across multiple browsers. This technology allows testing different browser environments without installing each browser individually, improving cross-browser compatibility testing efficiency.

Multiple choice technology architecture

One of the main features of this SDIS initiative is to “Builds the selected project and updates .classpath files with a valid WebSphere v6 JRE and WAS 6.0 runtime entries. Also add missing JARs from www by reading build error messages”. Identify this feature

  1. Classpath Repair plug-in

  2. Websphere Repair plug-in

  3. Classpath enhancer plug in

  4. JAR Enhancer Plug in
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Classpath Repair plug-in is specifically designed to build projects and automatically update .classpath files with the correct WebSphere v6 JRE and WAS 6.0 runtime entries. It also intelligently adds missing JARs by analyzing build error messages, which directly matches the described functionality.

Multiple choice technology architecture

Using a proxy method, ______ will allow developer J2EE workspaces to include only what is being changes. It will resolve all other dependency with from a stable external resource, decreasing server start-up times

  1. Minimal Server

  2. Classpath Repair plug-in

  3. Minimal J2EE Desktop Cloud

  4. Browser Virtualization
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Minimal J2EE Desktop Cloud uses a proxy method to include only changed components in developer workspaces while resolving other dependencies from a stable external resource. This approach significantly decreases server start-up times by reducing the overhead of loading unnecessary components.

Multiple choice technology architecture

__________, a plug-in approach, will allow J2EE test servers to include only the JVMs that are needed for a particular project. This initiative has made available 100 additional servers for project with no hardware cost to USAA

  1. Minimal J2EE Desktop Cloud

  2. Minimal Server

  3. Classpath Repair plug-in

  4. Browser Virtualization
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Minimal Server is a plug-in approach that allows J2EE test servers to include only the JVMs needed for a particular project, making 100 additional servers available with no hardware cost. This is different from Minimal J2EE Desktop Cloud which focuses on workspace optimization, and the other options are unrelated to server resource management.
