Question 1

All .html files can be processed by the web server itself.

Accepted Answer

The web server is capable of processing .html files and rendering them as web pages to be viewed by users.

Question 2

Open Database Connectivity is an application programming interface that provides a common language for application programs to access and process SQL databases independent of the particular RDBMS that is accessed.

Accepted Answer

This is an accurate description of Open Database Connectivity (ODBC).

Question 3

Storing XML data is becoming a big question as XML data becomes more prevalent.

Accepted Answer

XML data is becoming more commonly used, and finding efficient and effective ways to store it is becoming a bigger issue.

Question 4

A client/server configuration that has three layers (one client and two servers) has a three-tier architecture.

Accepted Answer

A three-tier architecture consists of three layers, with one client and two servers being a common example of this configuration.

Question 5

Document Type Declarations (DTDs) are unable to specify data types.

Accepted Answer

DTDs define the structure and hierarchy of elements in an XML document, but they do not provide a way to specify data types for element values or attributes. This is typically done through XML Schema or other validation mechanisms.

Question 6

Infrastructure-as-a-Service refers to the use of technologies such as servers, storage and networks from external service providers.

Accepted Answer

Infrastructure-as-a-Service (IaaS) is a type of cloud computing service that provides users with access to virtualized computing resources such as servers, storage, and networking equipment from an external service provider. Customers can use these resources as if they were their own data centers, but they do not have to manage or maintain the infrastructure themselves.

Question 7

Cloud computing will have a limited impact on three-tier applications.

Accepted Answer

Cloud computing can have a significant impact on three-tier applications by providing scalability, flexibility, and cost efficiency. They can be easily deployed, managed and maintained on cloud platforms, and can take advantage of various cloud services such as autoscaling, load balancing, and storage solutions.

Question 8

An XML Schema is a language used to define HTML.

Accepted Answer

An XML Schema is not used to define HTML. HTML has its own set of tags and rules for defining web pages, while XML is a markup language used for storing and transporting data. XML Schemas are used to define the structure, content, and data types within an XML document.

Question 9

Two-tier architectures are much more scalable than three-tier architectures.

Accepted Answer

Three-tier architectures are more scalable as they separate the presentation, application, and database layers, allowing for better distribution and management of resources. The addition of a middle tier also allows for better load balancing and fault tolerance.

Question 10

Java programs similar to applets that execute on the server are called hamlets.

Accepted Answer

Java programs similar to applets that execute on the server are called servlets, not hamlets.

Question 11

Application Programming Interfaces are more efficient than CGI scripts and are implemented as shared code or dynamic link libraries.

Accepted Answer

APIs are designed to be more efficient for communication between different applications or systems, while CGI scripts are used primarily for web applications. APIs are often implemented as shared code or dynamic link libraries, which can improve performance and reduce the amount of code that needs to be written.

Question 12

XML uses bcode, long commands embedded in quotes, to characterize data.

Accepted Answer

XML uses tags to characterize data, which are enclosed in angle brackets.

Question 13

Extensible Markup Language (XML) is a scripting language based upon SGML that allows the creation of customized tags.

Accepted Answer

XML is a markup language based upon SGML that allows the creation of customized tags.

Question 14

An HTTP Schema Definition is a language used for defining XML databases.

Accepted Answer

An HTTP Schema Definition or HTTPSD is not a language used for defining XML databases. Instead, it is a method for defining the structure and formatting of HTTP requests and responses. XML databases are typically defined using XML Schema Definition (XSD) or Document Type Definition (DTD).

Question 15

Three-tier architectures generally result in higher long-term costs.

Accepted Answer

Three-tier architectures actually result in lower long-term costs as they are more modular and maintainable, allowing for easier updates and scalability.

Question 16

Software as a service (SAAS) refers to an entire application or suite of applications running on the cloud.

Accepted Answer

Software as a service (SAAS) refers to a delivery model in which an entire application or suite of applications is hosted by a third-party provider and made available to customers over the internet. The software is accessed through a web browser or mobile app, and the provider is responsible for maintaining and updating the software.

Question 17

Stripping an XML document means storing each element of an XML schema in a relational table and using other tables to store the elements.

Accepted Answer

Stripping an XML document refers to removing unnecessary whitespace and formatting, not storing elements in relational tables.

Question 18

XML addresses the structuring and manipulation of information in a Web browser.

Accepted Answer

XML (Extensible Markup Language) is a standard format for structuring and representing data on the Web. It is used for sharing and transporting data between different systems and applications, as well as for displaying and manipulating data in a Web browser. XML provides a set of rules for creating custom tags and structures that allow developers to create more meaningful and semantically rich data formats.

Question 19

XML-based vocabularies, such as XBRL, do not allow meaningful comparisons to be made of data across many organizations.

Accepted Answer

XML-based vocabularies such as XBRL allow for standardized data exchange and enable meaningful comparisons of data across multiple organizations.

Question 20

Data returned on a web server is always in XML.

Accepted Answer

Data returned on a web server can be in various formats such as XML, HTML, JSON, plain text, etc. It depends on the server and how data is requested by the client.
