Oracle 1Z0-1113 Sample Questions:

01. What does JTA contribute to data access in a Helidon MP application?
a) It maps entity classes onto the tables and columns that store them.
b) It defines where a transaction begins and ends, and whether it commits.
c) It supplies the connection pool the persistence unit draws from.
d) It converts a query result into the objects the application works with.
 
02. An order service must notify a billing service and a shipping service whenever an order is placed. The notification must survive a downstream service being temporarily offline, and the order service must not wait for either of them.
Which communication style fits this requirement?
a) Call each downstream service over HTTP in turn and record the responses.
b) Invoke both downstream services over gRPC so the calls are efficient and strongly typed.
c) Publish an event to a message broker that the downstream services consume.
d) Have the downstream services poll the order service's REST endpoint on a schedule.
 
03. After a monolith was split, one page that previously rendered from a single in-process call now makes eleven network calls across four services, and its response time has tripled.
What does this most directly indicate?
a) Each of the four services needs more instances so that the calls complete faster.
b) The network between the services is misconfigured and adds latency to every hop.
c) The rendered page should be cached so that the eleven calls happen only once.
d) The boundaries force one user action to cross the network repeatedly.
 
04. Which two decisions does an orchestrator make from a Helidon service's health endpoints?
(Choose two.)
a) How many instances of the service should be running.
b) Whether to route requests to this instance.
c) Which version of the service to promote to production.
d) Whether to replace an instance that is no longer functioning.
 
05. An operator edits a value in the ConfigMap that supplies a Helidon service's settings. Some minutes later the running pods still behave according to the previous value.
Which explanation best accounts for this?
a) ConfigMap edits reach a pod only when the deployment's replica count changes.
b) The packaged configuration file outranks the ConfigMap, so the edit is being overridden.
c) The application read the value once at start-up and has no source watching for changes.
d) The value was converted to its target type at start-up, and conversions are cached permanently.
 
06. A team implements a MicroProfile Health liveness check that queries the application database. During a database outage, every replica of the service is repeatedly restarted by the orchestrator, and the outage takes longer to recover from.
What is the flaw in this design?
a) A liveness check is testing something a restart cannot repair.
b) The check should query the database less frequently to reduce the load it adds.
c) The check should be registered as a custom check rather than a built-in one.
d) The orchestrator's restart threshold is set too low for a check of this kind.
 
07. Which two benefits follow from supplying a Helidon service's configuration from outside the built artifact?
(Choose two.)
a) The same image can be promoted through several environments unchanged.
b) A setting can be changed without producing a new build of the application.
c) Configuration errors are detected during compilation rather than at run time.
d) Every configuration source becomes readable through the same ranking of precedence.
 
08. In the reactive model Helidon SE builds on, what does backpressure allow a consumer of a stream to do?
a) Pause the producer thread until the consumer has caught up.
b) Buffer the whole stream in memory before processing begins.
c) Signal how much data it is ready to receive.
d) Reorder incoming items so the most recent are processed first.
 
09. Which two tasks does the developer carry out explicitly when building a Helidon SE application?
(Choose two.)
a) Registering each handler against the path it should serve.
b) Supplying a qualifier so the runtime can choose between two candidate implementations.
c) Starting and stopping the server as part of the application's own lifecycle.
d) Declaring the media types an endpoint produces through annotations on the method.
 
10. What does MicroProfile OpenAPI provide to a Helidon MP application?
a) A client that calls another service from a declared Java interface.
b) A registry that records where each deployed service can be reached.
c) A validation layer that rejects requests not matching the declared schema.
d) A machine-readable description of the REST interface the service exposes.
