Introduction of Oracle 1z0-1084-25 Exam!

The 1z0-1084-25 exam is the current exam for the Oracle Cloud Infrastructure certification from Oracle. It validates the knowledge and hands-on skills described in the official Oracle Cloud Infrastructure Developer Professional syllabus, and it is the version of the exam that succeeds 1Z0-1084-22. Employers use Oracle Cloud Infrastructure as a hiring signal for professional-level roles, because it shows a candidate can do the work the certification describes, not just describe the theory.

What is the Competency Level required for Oracle 1z0-1084-25 Exam?

1z0-1084-25 is a professional-level exam. It assumes you are ready to apply the skills of Cloud Infrastructure Developer Professional in real working situations — the questions describe scenarios you would meet on the job and ask what you would do, rather than asking for definitions alone.

What is the Question Format of Oracle 1z0-1084-25 Exam?

The 1z0-1084-25 exam uses multiple-choice questions — mostly single best answer, with some multiple-response items that say so in the stem.

How Can You Take Oracle 1z0-1084-25 Exam?

You register through Oracle University and sit the exam with Pearson VUE — at a test center or as an online proctored exam from home. Either way you schedule at a time that suits you, pay with a voucher or card, and receive your score report as soon as you finish.

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?

Select all that apply, then click Submit answer.

○
Use OCI File Services as persistent volume.
○
Use GlusterFS as persistent volume.
○
Use OCI Block Volume backed persistent volume.
○
Use open source storage solutions on top of OCI.
○
Use OCI Object Storage as persistent volume.

Reference / correct answer:

Use OCI File Services as persistent volume.

Use OCI Block Volume backed persistent volume.

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.

GetMessages

https://docs.cloud.oracle.com/en-us/i aas/Content/Streaming/Concepts/streamingoverview.htm

Building consumers to read and process messages from a stream using the GetMessages API .

How Streaming Works:

The Streaming service provides a robust, scalable mechanism that you can use to produce and consume high volumes of data between application components.

Here's how Streaming works: a producer publishes messages to a stream, which is an append-only log. These messages are distributed among the partitions using the message's key.

Streams are divided into a number of partitions for scalability. Partitions allow you to distribute a stream by splitting messages across multiple nodes (or brokers). Each partition can be placed on a separate machine to allow multiple consumers to read a stream in parallel. Multiple consumers can read from any partition regardless of where the partition is hosted.

A consumer can read messages from one or more streams. Each message within a stream is marked with an offset value, so a consumer can pick up where it left off if it is interrupted.

You can use the Streaming service by:

A.Creating a stream using the Console or API.

B.Using a producer to publish data to the stream.

C. Building consumers to read and process messages from a stream using the GetMessages API . .

Question 8

You are working on a serverless DevSecOps application using Oracle Functions. You have deployed a Python function that uses the Oracle Cloud Infrastructure (OCI) Python SDK to stop any OC1 Compute instance that does not comply with your corporate security standards There are 3 non compliant OCI Compute instances.

However, when you invoke this function none of the instances were stopped. How should you troubleshoot this?

Select an option, then click Submit answer.

○
There is no way to troubleshoot a function running on Oracle Functions.
○
Enable function logging in the OCI console, include some print statements in your function code and use logs to troubleshoot this.
○
Enable function remote debugging in the OCI console, and use your favorite IDE to inspect the function running on Oracle Functions.
○
Enable function tracing in the OCI console, and go to OCI Monitoring console to see the function stack trace.

Reference / correct answer:

Enable function logging in the OCI console, include some print statements in your function code and use logs to troubleshoot this.

Storing and Viewing Function Logs:

When a function you've deployed to Oracle Functions is invoked, you'll typically want to store the function's logs so that you can review them later. You specify where Oracle Functions stores a function's logs by setting a logging policy for the application containing the function.

You can specify that Oracle Functions:

Stores logs in Oracle Cloud Infrastructure. Until an Oracle Cloud Infrastructure logging service is released, Oracle Functions stores logs as files in a storage bucket in Oracle Cloud Infrastructure Object Storage.

Note that to view function logs in a storage bucket, the group to which you belong must have been granted access with the following identity policy statements:

Allow group to manage object-family in compartment

Allow group to read objectstorage-namespaces in compartment (Usually created when configuring your tenancy for function development. See Create a Policy to Give Oracle Functions Users Access to Oracle Cloud Infrastructure Registry Repositories.)

Stores logs by exporting them to an external logging destination like Papertrail. Note that to use an external logging destination, you must have set up a VCN with public subnets and an internet gateway (see Create the VCN and Subnets to Use with Oracle Functions, if they don't exist already).

You set application logging policies in the Console.
