Q2a. Define Replication. Explain Full Replication and Partial Replication w.r.t distributed systems.

1. Elaborate on the Layers of Query Processing. 5+ 5

Ans 2.

1. Replication in Distributed Systems

Replication is a fundamental concept in distributed systems that involves creating and maintaining multiple copies of data across different nodes or servers. This approach enhances data availability, fault tolerance, and load balancing. Replication ensures that even if one node fails, the data can be

 

 

Q3a. Write a short note on Service Oriented Architecture

1. Explain Google File system 5+ 5

Ans 3.

1. Service-Oriented Architecture (SOA)

Service-Oriented Architecture (SOA) is a software design paradigm that enables the integration of diverse and distributed systems by encapsulating business functionalities as interoperable services. These services communicate over a network using standard protocols and data formats. The primary advantage of SOA is its modularity, reusability, and ease of integration, especially in heterogeneous IT environments. Each service is loosely coupled and self-contained, allowing organizations to build systems that are scalable,

Q4a. Explain the Set of Operations on WSDL with suitable code examples.

1. Identify the Cloud Security Methods. 5+ 5

Ans 4.

1. Set of Operations on WSDL with Code Example

WSDL (Web Services Description Language) is an XML-based language used to describe web services and specify the communication protocols and message formats. It acts as a contract between service providers and consumers, enabling seamless interoperability. WSDL defines a set of operations that a web service can perform, typically categorized under portType elements. Each operation includes

 

 

Q5a. Define a web browser. Explain about anyone in detail.

1. Evaluate the features of Nirvanix. 5+ 5

1. Web Browser and Explanation

A web browser is a software application used to access, retrieve, and display content from the World Wide Web. It interprets HTML documents, CSS styles, JavaScript, and multimedia, rendering them into human-readable web pages. Browsers use the HyperText Transfer Protocol (HTTP) or its secure version (HTTPS) to request content from web servers. Popular web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera.

Google Chrome is one of the

 

 

Q6a. Represent the Cloud Storage Architecture in Data Location.

1. Identify the challenges of Cloud Providers 5+ 5

Ans 6.

1. Cloud Storage Architecture in Data Location

Cloud storage architecture is the structural design of a storage system that allows users to store and access data over the internet. It comprises various components including storage infrastructure, management interfaces, APIs, and metadata services. A key feature of this architecture is its abstraction of physical data location, allowing users to access data from anywhere without knowing where it is physically stored.

At the core of cloud storage architecture is the client interface, where users interact via web portals, APIs, or file sync applications. The metadata manager maintains information about data, such as file name,
