Multiple choice technology architecture

What is Service Loose coupling in SOA?

  1. a) Logic is divided into services with the intention of promoting reuse

  2. b) Services maintain a relationship that minimizes dependencies and only requires that they maintain an awareness of each other

  3. c) Services have control over the logic they encapsulate

  4. d) Beyond what is described in the service contract, services hide logic from the outside world
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Service loose coupling in SOA means services maintain relationships that minimize dependencies and only require awareness of each other. This allows services to be modified or replaced without breaking the entire system. Option A refers to service reuse, C to service autonomy, and D to service abstraction - different SOA principles.

What is meant by Service statelessness in SOA Architecture?

  1. a) Services minimize retaining information specific to an activity

  2. b) Logic is divided into services with the intention of promoting reuse

  3. c) Collections of services can be coordinated and assembled to form composite services

  4. d) Beyond what is described in the service contract, services hide logic from the outside world
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Service statelessness in SOA means services minimize retaining information specific to an activity. This improves scalability by reducing memory requirements and allowing any service instance to handle any request. Statelessness is a key design principle in cloud and distributed systems.

What are the disadvantages of ESB?

  1. a) Enterprise Message Model is usually not mandatory

  2. b) Vendor not depending, it requires less hardware to run.

  3. c) Both a & b

  4. d) None of the Above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The disadvantages of an Enterprise Service Bus (ESB) include increased architectural complexity and high hardware overhead. Since none of the options accurately describe these drawbacks, 'None of the Above' is correct.

Which is the all-around central point of control responsible for all SOA orchestration?

  1. a) The enterprise service bus (ESB)

  2. b) The SOA registry

  3. c) Workflow engine

  4. d) SOA supervisor
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The SOA Supervisor is the central control point for all SOA orchestration, overseeing service levels, performance, and compliance across the ecosystem. The ESB handles messaging; Registry manages metadata; Workflow engine manages specific business processes.

What is Service Loose coupling in SOA?

  1. a) Logic is divided into services with the intention of promoting reuse

  2. b) Services maintain a relationship that minimizes dependencies and only requires that they maintain an awareness of each other

  3. c) Services have control over the logic they encapsulate

  4. d) Beyond what is described in the service contract, services hide logic from the outside world
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Service loose coupling means services minimize dependencies and only maintain awareness of each other through their contracts. This allows independent evolution and deployment. Option A describes service division, not coupling. Option C describes autonomy. Option D describes abstraction.

Multiple choice technology architecture

Which key features of SOA allow services to interact without being aware of each other's implementation details?

  1. Well-defined interfaces

  2. Loose coupling

  3. Service granularity

  4. Stateless service design
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

Well-defined interfaces (A) specify contracts without revealing implementation, allowing services to interact through public interfaces only. Loose coupling (B) means services have minimal dependencies on each other's internal details. Service granularity (C) is about functional scope size, not implementation hiding. Stateless design (D) avoids maintaining conversation state but doesn't address implementation awareness.

Multiple choice technology architecture

Which characteristic best distinguishes SOA technologies from previous approaches

  1. Loose coupling

  2. Object based

  3. Synchronous

  4. Fine-grained
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Loose coupling is the defining characteristic that distinguishes SOA from previous distributed approaches like CORBA, DCOM, or tight monolithic architectures. Loose coupling means services can evolve independently without breaking consumers. Object-based (B) is not unique to SOA, synchronous (C) isn't required, and SOA typically uses coarse-grained (not fine-grained) services.

Administration Server provides

  1. a. Central point from which to manage the domain.

  2. b. Distributed control over a domain.

  3. c. All the above

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

The Administration Server acts as the central management point for a WebLogic domain, controlling configuration and monitoring. It's not a distributed control system - that's what managed servers provide. Options C and D are incorrect because only A describes the Administration Server's role.

The Expansion for eSOA

  1. Extensible Service Oriented Architecture

  2. Extensible Schema of Application

  3. Enterprise Schema Oriented Application

  4. enterprise Service Oriented Architecture
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

eSOA stands for Enterprise Service Oriented Architecture, which is SAP's approach to service-oriented architecture for building flexible, reusable business services. The term emphasizes enterprise-grade services that can be orchestrated across applications.

What are container services?

  1. Life cycle management

  2. Security

  3. Deployment

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Web containers provide comprehensive services including lifecycle management (creating/destroying components), security (authentication/authorization), and deployment handling. These are core responsibilities of servlet/JSP containers.

Multiple choice technology

A hosted transparent decision service is a?

  1. rule-based application that runs in background on the operating system

  2. rule-based application deployed and running on a cluster

  3. rule-based application that triggers no rules

  4. dynamically generated web service that runs for a ruleset
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A hosted transparent decision service is a dynamically generated web service that exposes a ruleset for execution, allowing remote clients to invoke business rules without needing to know the implementation details. It is 'transparent' because the client sees only the service interface, not the underlying rule engine. It is not a background process or cluster deployment.

For High availability, how should Node Manager is configured in a WebLogic Domain?

  1. Node manager should be run a daemon or service on all machines that host Managed Server

  2. Node manager should be run a daemon or service on machine that host Administration Server

  3. Both a and b

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

For high availability, Node Manager should run as a daemon or service on every machine that hosts Managed Servers. This allows remote start/stop and auto-restart capabilities. Running Node Manager only on the Admin Server machine (option B) defeats the purpose since Managed Servers typically run on different machines.

what is Cloud?

  1. Internet Services

  2. Industry Infrastucture

  3. Collection of different IT optimization technique into one

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Multiple choice technology

The Basis of cloud computing is

  1. Infrasteucture Extension

  2. Platform Independency

  3. Man Power

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

Virtualization is the foundational technology that enables cloud computing. It allows physical hardware to be partitioned into multiple virtual machines, enabling resource sharing, scalability, and the on-demand provisioning model that defines cloud services. Without virtualization, modern cloud computing would not exist.
