1Z0-997-26 Practice Test 5 — 10 Questions

Question 1

An architect is configuring an OCI Full Stack Disaster Recovery plan. The plan includes a step to run a custom script on an application server during a failover drill. Which OCI service executes this custom script?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

OCI Functions or OCI Compute instance run-command actions orchestrated by Full Stack DR.. OCI Full Stack Disaster Recovery integrates with OCI Functions or custom scripts executed via instance agent / run command to perform pre-checks and custom automation steps.

Answer

Oracle Autonomous Linux Auto-Update Daemon

Answer

OCI Resource Manager Terraform apply jobs exclusively

Answer

OCI Streaming Service consumer groups

Question 2

Which OCI storage service provides massively scalable, highly durable regional object storage that is ideal for storing database backups and disaster recovery artifacts?

Accepted Answer

OCI Object Storage. OCI Object Storage is a regional, highly durable service designed for unstructured data storage, frequently used for backups and DR.

Answer

OCI Block Volume

Answer

Local NVMe Scratch Disks

Answer

OCI Boot Volumes

Question 3

Which THREE strategies are recommended when planning a large-scale database migration (exceeding 100 TB) from on-premises to Exadata Database Service on Dedicated Infrastructure with minimal downtime? (Choose three.)

Accepted Answer

Leveraging Transportable Tablespaces (TTS) combined with RMAN cross-platform conversion. Large-scale database migrations exceeding 100 TB benefit from transportable tablespaces, physical standby creation via RMAN, and Zero Downtime Migration (ZDM).

Answer

Copying database files across the public internet using standard FTP without encryption

Answer

Exporting the entire 100 TB database into a single plaintext SQL script using SQL*Developer

Question 4

When designing high availability across multiple Availability Domains in an OCI region, how should database or application subnets be configured to ensure fault tolerance?

Accepted Answer

Create regional subnets so that instances can be placed across multiple Availability Domains.. Subnets in OCI can be regional or AD-specific. For high availability across ADs, architects should deploy regional subnets or span instances across multiple AD-specific subnets.

Answer

Restrict all subnets to a single Availability Domain to prevent cross-AD latency.

Answer

Disable security lists on subnets to allow uninterrupted cross-AD replication traffic.

Answer

Attach all VNICs directly to the Dynamic Routing Gateway without using subnets.

Question 5

An enterprise application hosted on OCI requires high availability across multiple fault domains within a single availability domain. Which resource placement strategy should you use for your application compute instances?

Accepted Answer

Distribute instances evenly across three different Fault Domains.. Fault domains provide anti-affinity within an availability domain. Distributing instances across different fault domains ensures they do not share physical hardware, power, or top-of-rack switch infrastructure.

Answer

Configure a dedicated virtual cloud network for each fault domain.

Answer

Attach all instances to separate Internet Gateways.

Answer

Place all instances in Fault Domain 1 to optimize network latency.

Question 6

What is the primary purpose of OCI Database Actions (SQL Developer Web) when working with an Oracle Autonomous Database?

Accepted Answer

To provide a web-based development and management interface for executing SQL, querying data, and managing database users. OCI Database Actions provides a web-based interface for running SQL queries, developing PL/SQL, managing users, and loading data into Autonomous Database.

Answer

To configure physical Exadata storage cell disks and flash cache parameters

Answer

To monitor physical VCN packet drops and firewall logs

Answer

To manage OCI IAM user groups and federation settings across enterprise identity providers

Question 7

When planning a migration of Oracle databases to Oracle Autonomous Database (Serverless), which THREE migration methods or tools are natively supported or recommended by Oracle?

Accepted Answer

Oracle SQL Developer migration workbench / Data Loading features.. Autonomous Database Serverless supports specific migration paths including Oracle Zero Downtime Migration, Data Pump, and SQL Developer migration assistants.

Answer

Directly attaching on-premises ASM disk groups via iSCSI to the Autonomous container.

Answer

Direct physical RMAN full database restore to Autonomous storage.

Question 8

Which TWO OCI networking features help achieve high availability for applications accessing external services or on-premises datacenters? (Choose two.)

Accepted Answer

Redundant FastConnect virtual circuits terminating on separate DRG ports or diverse provider locations.. FastConnect redundant circuits and redundant IPSec VPN tunnels provide highly available hybrid connectivity.

Answer

Disabling Dynamic Routing Gateway route propagation.

Answer

Single public Internet Gateway attached without backup routes.

Answer

Using local peering gateways for on-premises connections.

Question 9

Which THREE operational tasks should be included in a comprehensive disaster recovery runbook when utilizing OCI Full Stack Disaster Recovery for an enterprise application? (Choose three.)

Accepted Answer

Executing pre-checks in the target DR region to validate resource readiness and configurations. An FSDR runbook should include verifying database synchronization, executing pre-checks before failover, starting application services via orchestrated plans, and updating DNS/load balancer routing.

Answer

Manually deleting all IAM policies in the primary region during normal operations

Answer

Format-all commands on primary database storage volumes prior to initiating DR

Question 10

Your organization uses OCI Full Stack Disaster Recovery to manage failovers between Region A and Region B. During a DR drill, you notice that a custom user-defined step failed because the dependent compute instance in Region B was not yet fully running. How should you resolve this dependency issue in the FSDR plan?

Accepted Answer

Edit the DR plan group and add a dependency or adjust the sequence order so that the start compute step completes before the custom script step.. OCI Full Stack Disaster Recovery allows you to configure plan groups and dependencies, ensuring that steps (such as running scripts or starting applications) wait until prerequisite infrastructure steps (like starting compute instances) complete successfully.

Answer

Manually SSH into each instance during the drill to run the script.

Answer

Increase the OCI Compute instance shape size in Region B to boot faster.

Answer

Disable all pre-checks in the FSDR plan settings.
