Cloud Computing Management Questions

Multiple choice technology web technology

Which two components provide workload management capabilities?

  1. Node Agent

  2. Web server Plug-in

  3. Caching proxy

  4. Deployment Manager

  5. Load Balancer
Reveal answer Fill a bubble to check yourself
B,E Correct answer
Explanation

Web server plug-ins distribute incoming requests across multiple application server instances, while load balancers distribute network traffic across multiple servers. Both are essential for managing workload distribution and preventing overload on any single component.

Which approach should be recommended when designing a production topology for WebSphere application servers providing high availability and failover capabilities?

  1. Create a design using multiple machines that handle the full production load, enabling the use

  2. Utilize load balancers between the Web servers and the application servers to provide failover

  3. Place the Authentication servers outside of the intrusion firewall with the Web servers, since

  4. Use the largest processor engines and least number of physical machines for the application
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The best practice for high availability is using multiple machines each capable of handling the full production load, allowing for failover when one machine fails. Load balancers alone between web and app servers don't provide complete HA. Authentication servers should be behind firewalls, not outside. Using fewer, larger machines creates a single point of failure.

Multiple choice technology architecture

What is the function of ESB?

  1. a) To transport the messages between software components

  2. b) contains information (metadata) about all the components that the SOA supports.

  3. c) provides reference information about software components that are running or available for use

  4. d) All the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Enterprise Service Bus (ESB) is the communication backbone that transports messages between different software components in an SOA architecture. It provides routing, transformation, and protocol mediation capabilities.

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
C Correct answer
Explanation

The Workflow Engine is the central orchestration point in SOA, responsible for coordinating all service interactions and business process execution. It manages the sequence and flow of service invocations to complete 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 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.

  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.
