Question 1

A CAP service exposes an entity as a projection. The project contains no JavaScript or Java implementation file at all. A client sends a GET request using $filter and $expand. What is the result?

Accepted Answer

CAP's generic providers serve the request, applying filter and expand

Answer

A 501 Not Implemented response, because no handler is registered

Answer

The request succeeds but returns all rows, as query options need code

Answer

Only $filter is applied; $expand needs a custom on handler to resolve

Question 2

A developer seeds data using db/data/my.bookshop-Books.csv with the header row ID;title;author. The books load successfully, but every book's author association is empty. What is wrong?

Accepted Answer

The column must be named author_ID to match the generated foreign key

Answer

The header must be comma-separated, because CAP cannot parse semicolons

Answer

Associations cannot be seeded from CSV files; they require a handler

Answer

A second file mapping books to authors is needed for the link table

Question 3

A service must expose an operation that recalculates and updates the totals of an order. Which construct should be used, and what must the developer provide?

Accepted Answer

An action, implemented in a custom on handler

Answer

A function, served automatically from the entity projection

Answer

An action, implemented automatically by the generic providers

Answer

A function, implemented in a custom on handler

Question 4

An Order must own its OrderItems: deleting an order must delete its items, and a client must be able to create an order together with its items in a single request. Which modelling construct provides both behaviours?

Accepted Answer

Composition of many OrderItems on items.parent = $self

Answer

Association to many OrderItems on items.parent = $self

Answer

Association to many OrderItems, annotated with @assert.target

Answer

Association to many OrderItems, annotated with @cds.autoexpose

Question 5

Within a service that carries no service-level authorization annotation, an entity is annotated @restrict: [{ grant: 'READ' }] with no 'to' key specified. Who is able to read the entity?

Accepted Answer

Everyone, including users who are not authenticated

Answer

Nobody, because no role has been granted access

Answer

Only users holding the internal-user pseudo-role

Answer

Only authenticated users, whatever their roles are

Question 6

A developer registers srv.on('READ', 'Books', ...) and the handler returns a value without ever calling next(). What happens to CAP's default database read?

Accepted Answer

It does not run, because the custom handler replaces the generic one

Answer

It runs first, and the custom handler then post-processes its result

Answer

It runs only when the custom handler returns undefined

Answer

It runs in parallel and the two result sets are merged

Question 7

A developer has installed the Cloud Foundry CLI and successfully produced an .mtar archive. Running cf deploy returns an unknown-command error. What is missing?

Accepted Answer

The MultiApps CF CLI plugin, which provides cf deploy

Answer

An active cf login session targeting an org and space

Answer

The Cloud MTA Build Tool, which registers the command

Answer

A manifest.yml describing the apps to be deployed

Question 8

A developer runs npm install @cap-js/hana instead of cds add hana. Which step does the npm command leave undone?

Accepted Answer

Updating the project configuration so CAP uses SAP HANA

Answer

Nothing, because cds add hana simply runs the same npm install

Answer

Provisioning of the HDI container inside the SAP BTP subaccount

Answer

Generation of the gen/db folder holding the deployment artefacts

Question 9

Besides writing a model file into srv/external/, what else does cds import change in the project?

Accepted Answer

It adds a cds.requires entry for the imported service

Answer

It creates database tables for each imported entity

Answer

It registers a destination in the SAP BTP subaccount

Answer

It adds the remote service to mta.yaml as a resource

Question 10

A handler validates three separate fields and must report every failure to the client in a single response. Which approach achieves this?

Accepted Answer

Call req.error() once for each field that fails validation

Answer

Call req.reject() once for each field that fails validation

Answer

Throw a new Error per field and catch them at service level

Answer

Call req.notify() per field, then req.reject() at the end
