Question: 1 
   
Which one of the statements describes a service aggregator pattern? 
 
A. It is implemented in each service separately and uses a streaming service 
B. It involves implementing a separate service that makes multiple calls to other backend services 
C. It uses a queue on both sides of the service communication 
D. It involves sending events through a message broker 
 
Answer: B     
 
Explanation: 
this pattern isolates an operation that makes calls to multiple back-end microservices, centralizing its 
logic into a specialized microservice. 
 
Question: 2 
   
Which two statements accurately describe an Oracle Functions application? 
 
A. A small block of code invoked in response to an Oracle Cloud Infrastructure (OCI) Events service 
B. A Docker image containing all the functions that share the same configuration 
C. An application based on Oracle Functions, Oracle Cloud Infrastructure (OCI) Events and OCI API 
Gateway services 
D. A common context to store configuration variables that are available to all functions in the 
application 
E. A logical group of functions 
 
Answer: DE     
 
Explanation: 
Applications in the Function services 
In Oracle Functions, an application is: 
- a logical grouping of functions 
- a common context to store configuration variables that are available to all functions in the 
application 
When you define an application in Oracle Functions, you specify the subnets in which to run the 
functions in the application. 
 
Question: 3 
   
You have been asked to create a stateful application deployed in Oracle Cloud Infrastructure (OCI) 
Container Engine for Kubernetes (OKE) that requires all of your worker nodes to mount and write 
 
data to persistent volumes. 
Which two OCI storage services should you use? 
 
A. Use OCI File Services as persistent volume. 
B. Use GlusterFS as persistent volume. 
C. Use OCI Block Volume backed persistent volume. 
D. Use open source storage solutions on top of OCI. 
E. Use OCI Object Storage as persistent volume. 
 
Answer: AC     
 
Explanation: 
A PersistentVolume (PV) is a piece of storage in the cluster that has been provisioned by an 
administrator. PVs are volume plugins like Volumes, but have a lifecycle independent of any 
individual Pod that uses the PV. 
A PersistentVolumeClaim (PVC) is a request for storage by a user. It is similar to a Pod. Pods consume 
node resources and PVCs consume PV resources. 
If you intend to create Kubernetes persistent volumes, sufficient block volume quota must be 
available in each availability domain to meet the persistent volume claim. Persistent volume claims 
must request a minimum of 50 gigabytes 
You can define and apply a persistent volume claim to your cluster, which in turn creates a persistent 
volume that's bound to the claim. A claim is a block storage volume in the underlying IaaS provider 
that's durable and offers persistent storage, enabling your data to remain intact, regardless of 
whether the containers that the storage is connected to are terminated. 
With Oracle Cloud Infrastructure as the underlying IaaS provider, you can provision persistent volume 
claims by attaching volumes from the Block Storage service. 
 
Question: 4 
   
You are a consumer of Oracle Cloud Infrastructure (OCI) Streaming service. Which API should you use 
to read and process the stream? 
 
A. ListMessages 
B. GetMessages 
C. GetObject 
D. ReadMessages 
 
Answer: B     
 
Explanation:

Building consumers to read and process messages from a stream using the GetMessages API . 
 
Question: 5 
 
   
Which two handle Oracle Functions authentication automatically? 
 
A. Oracle Cloud Infrastructure SDK 
B. cURL 
C. Oracle Cloud Infrastructure CLl 
D. Signed HTTP Request 
E. Fn Project CLI 
 
Answer: CE     
 
Explanation: 
Fn Project CLI 
you can create an Fn Project CLI Context to Connect to Oracle Cloud Infrastructure and specify -- 
provider oracle This option enables Oracle Functions to perform authentication and authorization 
using Oracle Cloud Infrastructure request signing, private keys, user groups, and policies that grant 
permissions to those user groups.
