1Z0-1085-25 Sample Questions

  1. Question 1

    Intermediate

    Getting Started with OCI · OCI Distributed Cloud

    A multinational financial institution requires a cloud deployment that guarantees data never leaves their primary country of operations due to strict regulatory compliance, yet they need the agility and pricing model of the public cloud. They also require low-latency connectivity to their existing on-premises mainframe systems. Which OCI deployment model best fits these specific requirements?

    Answer and explanation

    Correct answer: C

    OCI Dedicated Region provides all the services of the public cloud (IaaS, PaaS, SaaS) within the customer's own data center. This satisfies the strict data residency requirement (data stays on-prem) and low-latency connectivity to mainframes, while offering the consumption-based pricing model of the cloud.

  2. Question 2

    Beginner

    Getting Started with OCI · OCI Regions and Availability Domains

    You are designing a highly available web application in the Frankfurt region (which has 3 Availability Domains). The application requires redundancy against the failure of an entire data center. How should you distribute the compute instances to achieve this with the highest fault tolerance?

    Answer and explanation

    Correct answer: A

    Availability Domains (ADs) are physically isolated data centers within a region. Deploying across multiple ADs protects against the failure of a single AD (data center). Fault Domains only protect against rack/power failures within a single AD.

    graph TD Region[OCI Region: Frankfurt] --> AD1[Availability Domain 1] Region --> AD2[Availability Domain 2] Region --> AD3[Availability Domain 3] AD1 --> VM1[Web Server 1] AD2 --> VM2[Web Server 2] AD3 --> VM3[Web Server 3] style AD1 fill:#f9f,stroke:#333,stroke-width:2px style AD2 fill:#f9f,stroke:#333,stroke-width:2px style AD3 fill:#f9f,stroke:#333,stroke-width:2px

  3. Question 3

    Intermediate

    Security Services · Identity and Access Management

    A solutions architect is designing a new OCI tenancy structure for a large conglomerate. The organization has three distinct subsidiaries, each requiring independent cost tracking and resource isolation. However, the central IT team needs the ability to manage policies across all subsidiaries. Which hierarchical structure best supports these requirements?

    Answer and explanation

    Correct answer: B

    Compartments are the primary tool for resource isolation and cost management within a tenancy. Creating top-level compartments for each subsidiary allows for distinct policies, budgets, and resource separation while maintaining a single tenancy for centralized administration by the parent company.

  4. Question 4

    IntermediateMultiple answers

    Getting Started with OCI · OCI Regions and Availability Domains

    Which of the following statements accurately describes the behavior of OCI Fault Domains? (Select TWO)

    Answer and explanation

    Correct answers: A, C

    Fault Domains are groupings of hardware and infrastructure within an Availability Domain, effectively acting as logical data centers to prevent single points of failure.

    Every Availability Domain in OCI is partitioned into three Fault Domains. This allows you to distribute instances so that they do not share the same physical hardware.

  5. Question 5

    Advanced

    Security Services · Identity and Access Management

    A developer needs to automate the provisioning of OCI resources using Terraform. They want to authenticate the Terraform provider without embedding a user's private key or password in the script, and the script will run from an existing OCI Compute instance. What is the most secure method to achieve this?

    Answer and explanation

    Correct answer: C

    Instance Principals allow instances to be authorized actors (principals) to perform actions on service resources. By placing the instance in a Dynamic Group and writing a policy for that group, the instance can authenticate without storing static credentials, eliminating the risk of key leakage.

  6. Question 6

    Intermediate

    Core OCI Services · Compute Services

    You are migrating a legacy application to OCI. The application requires a specific older version of the operating system that is not available in the standard Oracle images. You have created a custom image of the VM on your on-premises virtualization platform. Which OCI service feature facilitates bringing this image into the cloud?

    Answer and explanation

    Correct answer: D

    OCI allows you to import custom images from Object Storage. You can upload your QCOW2 or VMDK file to an Object Storage bucket and then use the Compute service to import it as a Custom Image, which can then be used to launch instances.

  7. Question 7

    IntermediateMultiple answers

    Core OCI Services · Networking Services

    A customer is setting up a Virtual Cloud Network (VCN) with a CIDR block of 10.0.0.0/16. They need to create a subnet for web servers that will receive traffic directly from the internet. Which two components are MANDATORY for this specific subnet configuration to work as intended? (Select TWO)

    Answer and explanation

    Correct answers: A, D

    Even with an Internet Gateway attached, the subnet needs a Route Table with a rule explicitly directing traffic destined for the internet (0.0.0.0/0) to the Internet Gateway.

    graph LR Subnet[Public Subnet] -->|Route 0.0.0.0/0| RT[Route Table] RT --> IGW[Internet Gateway] IGW --> Internet((Internet))

    An Internet Gateway is required to provide a path for network traffic between the VCN and the internet. Without it, no resource in the VCN can be reached from the outside world.

  8. Question 8

    Beginner

    Core OCI Services · Database Services

    Your organization requires a database solution for an analytics workload that involves analyzing massive amounts of data from IoT sensors. The workload is unpredictable, and you want to minimize administration tasks like patching, tuning, and scaling. Which OCI Database service is the optimal choice?

    Answer and explanation

    Correct answer: C

    Autonomous Data Warehouse is specifically optimized for analytics workloads (Columnar format, data summarization). Being 'Autonomous', it self-patches, self-tunes, and supports auto-scaling, meeting the requirement to minimize administration.
