1.
EMS is
Correct Answer
A. For aligning enterprise data across multiple business units, departments and partners
Explanation
The correct answer is for aligning enterprise data across multiple business units, departments, and partners. This suggests that EMS is a tool or system that helps in organizing and synchronizing data within an organization, ensuring that data is consistent and accessible across different units, departments, and external partners. It implies that EMS plays a crucial role in facilitating data integration and collaboration, enabling efficient and effective decision-making processes within the enterprise.
2.
EMS usually takes into account the following considerations except
Correct Answer
A. Speed
Explanation
EMS, or Enterprise Management System, is a comprehensive software solution that helps organizations manage their operations effectively. It encompasses various aspects such as security, routing, and policy management. However, speed is not typically considered as a primary consideration in EMS. While it is important for systems to perform efficiently, the focus of EMS is more on ensuring security, managing network routing, and implementing organizational policies. Therefore, speed is not a consideration in EMS.
3.
EMS are also known as MOM which stands for
Correct Answer
C. Message Oriented Middleware
Explanation
EMS stands for Message Oriented Middleware (MOM). MOM is a software architecture that allows applications to send and receive messages asynchronously. It provides a reliable and scalable messaging infrastructure for distributed systems. EMS enables communication between different applications or components by sending messages through a middleware layer. This allows for decoupling of sender and receiver, ensuring reliable delivery and providing features like message queuing, publish/subscribe, and message transformation. Therefore, the correct answer is Message Oriented Middleware.
4.
EMS ia usually broken down into how many sections?
Correct Answer
D. Two
Explanation
EMS is usually broken down into two sections. This means that the EMS system is typically divided into two main components or categories. The question is asking for the number of sections in EMS, and the correct answer is two.
5.
Message headers are usually coded in clear text so that
Correct Answer
C. Intermediate nodes receive all the necessary information they need to route and prioritize the message
Explanation
Message headers are usually coded in clear text so that intermediate nodes receive all the necessary information they need to route and prioritize the message. By encoding the headers in clear text, intermediate nodes can easily understand and interpret the information, allowing them to make informed decisions on how to handle the message. This ensures that the message is correctly routed and prioritized based on the information provided in the headers.
6.
One of these is true about MOM
Correct Answer
A. It allows application modules to be distributed over heterogeneous platforms
Explanation
MOM, or Message-Oriented Middleware, allows application modules to be distributed over heterogeneous platforms. This means that MOM enables communication and integration between different types of platforms, such as different operating systems or hardware architectures. By using MOM, application modules can seamlessly interact and exchange messages across diverse platforms, promoting interoperability and flexibility in distributed systems.
7.
Why must messages be authenticated or digitally signed?
Correct Answer
D. All of the above
Explanation
Messages must be authenticated or digitally signed to ensure the accuracy, consistency, and integrity of the data being transmitted. This helps to assure both the sender and receiver that the message has not been modified while in transit and that the source of the message can be verified. By authenticating or digitally signing messages, the receiver can have confidence that the messages have not been tampered with during transmission.
8.
EMS places emphasis on design of messaging protocols using one of the following
Correct Answer
A. MSMQ
Explanation
EMS places emphasis on design of messaging protocols using MSMQ. MSMQ (Microsoft Message Queuing) is a messaging protocol developed by Microsoft that allows applications running on separate servers or devices to communicate with each other asynchronously. It provides reliable message delivery, transactional support, and scalability. EMS, which stands for Enterprise Messaging System, focuses on designing messaging protocols, and MSMQ is one of the options available for this purpose. JMS (Java Message Service), Web services, and .NET are also commonly used for messaging protocols, but in this case, the emphasis is on MSMQ.
9.
An example of a specific application programming interface (API) that implements an enterprise messaging system is the
Correct Answer
A. ESB
Explanation
ESB (Enterprise Service Bus) is an example of a specific application programming interface (API) that implements an enterprise messaging system. ESB is a software architecture that allows different applications to communicate and exchange data with each other. It provides a centralized platform for managing and routing messages between various systems in an enterprise. ESB enables seamless integration and interoperability between different applications, making it an ideal choice for implementing an enterprise messaging system.
10.
One of the types of metadata describes the types, versions, relationships and other characteristics of digital materials, which one?
Correct Answer
C. Structural MetadataÂ
Explanation
Structural metadata describes the organization and relationships between different components of digital materials. It provides information about how the digital materials are structured and how they are related to each other. This type of metadata is commonly used in the management and organization of digital collections, helping users navigate and access the content effectively. It includes information about the hierarchy, sequence, and arrangement of the digital materials, enabling users to understand the overall structure and organization of the content.
