Do You Know About Cognos Company?

The dispatcher is coded in Java.

Cognos is a web-based interface because it is accessed through a web browser. This means that users can access and interact with Cognos from any device with internet access, without the need to install any additional software. This allows for greater flexibility and convenience, as users can access Cognos from anywhere at any time. Additionally, being web-based also allows for easier updates and maintenance, as changes can be made centrally and applied to all users simultaneously.

The correct answer is "windows based." This means that the framework manager is designed to work specifically on the Windows operating system.

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.

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.

The correct answer is tier3. In the architecture, tier 3 is where the database is accessed. This tier is responsible for storing and retrieving data from the database. It is typically located on a separate server or cluster of servers and is accessed by the application layer in tier 2. Tier 3 ensures data integrity, security, and efficient storage and retrieval of data for the application.

The Cognos BI Bus is used to transfer data from one tier to another in the Cognos Business Intelligence system. It acts as a communication channel between different components of the system, allowing them to exchange data and information. The BI Bus ensures seamless integration and smooth flow of data between the various tiers, such as the web server, application server, and gateways. It plays a crucial role in enabling data transfer and communication within the Cognos BI environment.

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.

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.

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.

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.

The correct answer is "Single server configuration." This means that the report net system is set up with only one server. In this configuration, all the necessary components and services for generating and distributing reports are hosted on a single server. This setup is suitable for smaller organizations or scenarios where the workload is not too heavy.

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.

The correct answer is "directory". In ReportNet, the directory defines the roles and groups that can access and interact with the reports. It acts as a central repository where user information, permissions, and access controls are stored. The directory helps in managing user authentication, authorization, and security within the reporting system. By defining roles and groups in the directory, administrators can control the level of access and functionality available to different users in ReportNet.

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.
