4.
Which of the following comes under webserver tier?
Correct Answer(s)
A. CGI servlet.
B. Microsoft iis.
C. Netscape ws.
Explanation
The webserver tier is responsible for handling HTTP requests and serving web pages to clients. CGI servlet, Microsoft IIS, and Netscape WS are all examples of web servers that operate at this tier. CGI servlet is a technology that allows web servers to execute CGI scripts, Microsoft IIS is a popular web server software developed by Microsoft, and Netscape WS is a web server software developed by Netscape Communications Corporation. Therefore, all three options mentioned in the answer (CGI servlet, Microsoft IIS, and Netscape WS) are correct choices for the webserver tier.
5.
_____________ is a main entry point for inbound requests from Web server gateway?
Correct Answer
C. Dispatcher
Explanation
The correct answer is "dispatcher." In the context of inbound requests from a web server gateway, the dispatcher serves as the main entry point. It receives and directs incoming requests to the appropriate components or services within the system. The dispatcher plays a crucial role in managing and routing the requests efficiently, ensuring smooth communication between the web server and other parts of the system.
6.
What are the tasks of tier2 (application tier)?
Correct Answer(s)
C. presentation
D. Notificaton
E. Reporting
Explanation
The tasks of tier 2 (application tier) include presentation, notification, and reporting. The presentation refers to the user interface or front-end of the application, which displays information and interacts with the user. Notification involves sending alerts or messages to users, keeping them informed about important updates or events. Reporting involves generating and presenting data or information in a structured format, allowing users to analyze and make informed decisions based on the data. These tasks are typically handled by the application tier, which is responsible for processing and managing the business logic of the application.
7.
______________Determines which service performs the request?
Correct Answer
C. Requst delivery
Explanation
The correct answer is "request delivery." This is because the term "request delivery" refers to the process of delivering a request to the appropriate service or server that can handle it. In a distributed system or network, there may be multiple services or servers available to handle requests, and the request delivery mechanism determines which specific service should receive and process each request. This ensures that the request is directed to the appropriate service and allows for efficient and effective handling of incoming requests.
8.
_____________Redirect requests to other dispatchers
Correct Answer
B. Load balencing
Explanation
The given correct answer is "Load balancing". Load balancing refers to the process of distributing incoming requests across multiple servers or resources to ensure that no single server or resource is overwhelmed with too much traffic. This helps in optimizing resource utilization, improving response times, and enhancing overall system performance. By redirecting requests to other dispatchers, load balancing ensures that the workload is evenly distributed and efficiently managed, resulting in better request delivery and overall system performance.
9.
JSC in tier3 means ______?
Correct Answer
B. Java servelt container
Explanation
JSC in tier3 means Java servlet container. A Java servlet container is a runtime environment that provides the necessary infrastructure for executing Java servlets. It manages the lifecycle of servlets, handles incoming requests, and dispatches them to the appropriate servlet for processing. In a tier3 architecture, the Java servlet container would be responsible for hosting and managing the servlets that handle the business logic and data processing of the application.
10.
reprot service is present in_____________?
Correct Answer
C. Application server
Explanation
The "report service" is typically found in an application server. Application servers are responsible for hosting and managing applications, including services such as generating and delivering reports. Web browsers are used to access and display web content, while web servers handle requests and deliver web pages. A database server is used to store and manage data. Therefore, the most appropriate place for a report service would be an application server.
11.
Report net is also called as______________?
Correct Answer
A. Application tier
Explanation
The application tier, also known as the middle tier or logic tier, is responsible for processing and managing the business logic of an application. It acts as a bridge between the presentation layer (web browser) and the data layer (data tier). It handles tasks such as authentication, authorization, data validation, and business rules. Therefore, the correct answer is the application tier.
12.
_____________ defines roles and groups in report net?
Correct Answer
A. Directory
Explanation
