1. What is semantic interoperability?
Question 1A. Exchanging semantic information across systems, departments or organisationsB. Encrypting data before it is sharedC. Copying a database from one server to anotherD. Translating documents into multiple languagesE. Standardising country codes for locations
2. How can the same salary data mean different things to HR and Finance?
Question 2A. HR stores salary as text while Finance stores it as a numberB. HR uses salary to see who is paid what and to benchmark new hires, while Finance uses it to calculate the company's annual expenseC. HR and Finance always interpret salary identicallyD. HR is not permitted to see salary dataE. Finance only records salary in a different currency
3. On what is a semantic layer in a decision support system based?
Question 3A. The physical storage format of the disksB. The vendor's default database schemaC. Business requirements, expressed in the business's own language, key words and codesD. The network topology of the organisationE. The programming language used by developers
4. What is interoperability about?
Question 4A. Deleting duplicate information across systemsB. Restricting information to one departmentC. Converting analogue records to digitalD. Exchanging something across systems so others do not need to regenerate it again and againE. Backing up data to a remote location
5. What is the main challenge that comes with semantic interoperability?
Question 5A. The cost of network bandwidthB. The size of the tables being exchangedC. The speed of the database engineD. The number of users who need accountsE. Whether the receiving party can understand the sending party's keywords, symbols and terminologies
6. In the medical industry example of semantic interoperability, what must happen when semantic-layer tables are shared with another department?
Question 6A. The receiving department must be able to understand what the data means, or the information is uselessB. The tables must first be converted to a NoSQL formatC. The data must be deleted after it is readD. The receiving department must rebuild the tables from scratchE. The tables must be printed for archival
7. Under which approach does semantic interoperability become virtually impossible without data governance?
Question 7A. Centralised approachB. Federated approachC. Batch approachD. Streaming approachE. Monolithic approach
8. Why are semantics said to be different for everyone in an organisation?
Question 8A. Because every department uses a different database vendorB. Because data is stored in different countriesC. Because each department has its own semantics for viewing data, so the same data can have different meaningsD. Because employees speak different languagesE. Because semantics change every financial year
9. Which of the following is NOT part of semantic interoperability as described?
Question 9A. Exchanging semantic information across organisationsB. Ensuring the receiver understands the sender's terminologyC. Sharing semantic-layer tables between departmentsD. Physically relocating servers between data centresE. Relying on data governance in a federated setting
10. What is the purpose of semantic interoperability with respect to information already generated by one party?
Question 10A. To ensure the information is regenerated by every party independentlyB. To restrict the information to its original authorC. To convert the information into a physical modelD. To archive the information permanentlyE. To exchange the information so others do not need to regenerate it again and again
