Questions 1–10 of 10

1. How does the Point-to-Point (PP) integration model connect applications?
Question 1A. Every application connects with every other application directlyB. Every application connects only to one central hubC. Applications connect through a message queue onlyD. Applications never connect; data is moved manuallyE. Only two applications may exist in the model
2. In the Hub-and-Spoke model, how do applications connect?
Question 2A. Each application connects with every other applicationB. All applications connect only with one centralised hubC. Applications connect in a ring, each to its neighbourD. Applications connect to several regional hubs at onceE. Applications share a single database table
3. Which of the following are given as examples of the Hub-and-Spoke model?
Question 3A. Spreadsheets, email and file sharesB. Web servers, load balancers and cachesC. Dimensional Data Warehouse, Data Hub and Data FabricD. Mobile apps and browser extensionsE. Firewalls and VPNs
4. Why is security considered better in the Hub-and-Spoke model than in Point-to-Point?
Question 4A. Because the hub encrypts every message automaticallyB. Because Point-to-Point has no authentication at allC. Because the hub is hosted off-siteD. Because all users connect to one centralised hub, so the risk of a security breach is lowerE. Because Hub-and-Spoke uses fewer applications
5. How does the Hub-and-Spoke model handle user access compared with Point-to-Point?
Question 5A. It removes the need for user access managementB. It requires each application to manage its own access matrixC. It grants all users the same permissionsD. It delegates access to the source systemsE. It manages the user access matrix at a centralised place
6. Why is the Hub-and-Spoke model described as more flexible than Point-to-Point?
Question 6A. The hub makes it easy to incorporate new requirements without implementing them in source systemsB. Each application can be replaced without any change to the hubC. It has no fixed data modelD. It works without any initial investmentE. It supports only one application at a time
7. What is said about the cost of the Hub-and-Spoke model?
Question 7A. It is always cheaper from day one with no initial investmentB. It requires initial investment, but afterwards new requirements are much cheaper because changes go into the hubC. It is more expensive than Point-to-Point in every caseD. Cost is identical to Point-to-PointE. Cost depends only on the number of users
8. Which of the following is NOT listed as an advantage of Hub-and-Spoke over Point-to-Point?
Question 8A. Better user access managementB. Lower security breach riskC. Greater flexibility for new requirementsD. Zero implementation effortE. Cheaper handling of new requirements after initial investment
9. In the Point-to-Point model, where must a new requirement be implemented?
Question 9A. Only in the central hubB. Only in the data warehouseC. In each applicationD. In the semantic layerE. Nowhere; requirements are handled automatically
10. Hub-and-Spoke examples such as the Data Warehouse, Data Hub and Data Fabric serve what role for enterprise users?
Question 10A. A backup archiveB. A development sandboxC. A message brokerD. A firewallE. A single point of truth
