1Z0-1085-26 Practice Test 26 — 15 Questions

Question 1

An enterprise cloud architect is evaluating OCI's distributed cloud model and wants to understand how resource management, IAM policies, and API endpoints are handled across a customer's OCI Dedicated Region compared to standard public regions. Which statement accurately describes the control plane architecture?

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

Accepted Answer

Dedicated regions share the same public cloud control plane, APIs, and management tools, ensuring identical operational experiences.. OCI Dedicated Regions are managed remotely by the same control plane and APIs used in OCI public regions, ensuring uniform management while data remains local.

Answer

Dedicated regions cannot access native OCI services like Object Storage or Autonomous Database.

Answer

Dedicated regions do not support Identity and Access Management (IAM) because they are entirely disconnected from Oracle.

Answer

Dedicated regions require a completely isolated, on-premises local control plane managed independently by local administrators.

Question 2

Which TWO OCI concepts are fundamental for organizing resources and managing access control within a tenancy? (Choose two.)

Accepted Answer

Compartments. Compartments are used to organize and isolate resources, and IAM policies control who can access those resources within compartments.

Answer

Availability Domains

Answer

Fault Domains

Answer

Internet Gateways

Question 3

An administrator needs to deploy a critical production database across multiple data centers in the same OCI region to protect against unexpected hardware failure while ensuring lowest possible network latency for synchronous replication. Which component should the administrator leverage?

Accepted Answer

Availability Domains. Availability Domains (ADs) are isolated, independent data centers within a region, connected with high-performance, low-latency networks, making them ideal for high availability within the same region.

Answer

OCI Dedicated Regions

Answer

OCI Regions

Answer

Fault Domains

Question 4

You want to delegate the ability to create and manage sub-compartments within an existing compartment called 'AppCompartment' to a lead architect, without granting them full tenancy administration rights. How should you write this IAM policy?

Accepted Answer

Allow group ArchitectGroup to manage compartments in compartment AppCompartment. To allow managing compartments within a specific parent compartment, the policy must target the 'compartments' resource type at the parent compartment level.

Answer

Allow group ArchitectGroup to manage root-compartment in tenancy

Answer

Allow group ArchitectGroup to use compartments in tenancy

Answer

Allow group ArchitectGroup to manage tenancy in compartment AppCompartment

Question 5

Which TWO statements describe OCI Service Limits? (Choose two.)

Accepted Answer

Service limits restrict the maximum amount of a resource you can consume in a tenancy or region.. Service limits are thresholds set on resource consumption per tenancy/region, and administrators can request increases via the console.

Answer

Service limits cannot be increased under any circumstances.

Answer

Service limits are managed entirely by writing IAM policy statements.

Answer

Service limits apply only to Object Storage and cannot restrict compute or networking.

Question 6

A financial services company needs to ensure that their database primary and standby nodes are never placed on the same physical infrastructure rack, despite being in the same data center building. What configuration satisfies this?

Accepted Answer

Place the primary node in Fault Domain 1 and the standby node in Fault Domain 2.. Assigning the primary and standby nodes to separate fault domains ensures they reside on different physical hardware racks.

Answer

Place both nodes in different compartments.

Answer

Place both nodes in Fault Domain 1.

Answer

Place both nodes in the root tenancy.

Question 7

In an OCI region with a single availability domain, how does OCI achieve high availability and fault isolation for compute workloads?

Accepted Answer

By utilizing multiple fault domains within that single availability domain.. In regions with a single availability domain, OCI relies on multiple fault domains to distribute workloads across isolated physical hardware.

Answer

By provisioning multiple availability domains dynamically behind the scenes.

Answer

By requiring users to manually peer across international regions.

Answer

High availability is not possible in single-AD regions.

Question 8

Which TWO options correctly describe features of OCI Regions? (Choose two.)

Accepted Answer

Regions are completely independent and do not share infrastructure with other regions.. OCI regions are localized geographic areas containing one or more availability domains, and each region is independent and autonomous.

Answer

Every OCI region is guaranteed to have exactly three availability domains.

Answer

Regions span across multiple continents simultaneously.

Answer

Regions are logical constructs used exclusively for billing purposes.

Question 9

What is a key benefit of OCI's multi-region architecture for enterprise disaster recovery?

Accepted Answer

It allows organizations to deploy workloads across geographically disparate regions to protect against large-scale regional disasters.. Multi-region architecture enables disaster recovery by placing backup infrastructure in a geographically separate region.

Answer

It eliminates the need for data backups by synchronizing all data locally across fault domains.

Answer

It ensures that all regions share the same physical power grid to reduce energy consumption.

Answer

It allows developers to bypass IAM security policies when migrating data between regions.

Question 10

Which TWO statements are true regarding the connectivity between OCI Availability Domains within a region? (Choose two.)

Accepted Answer

Traffic between Availability Domains within the same region travels over a high-bandwidth, low-latency network fabric.. ADs within a region are connected by a high-speed network fabric and do not incur standard internet egress fees.

Answer

Traffic between Availability Domains must traverse public internet gateways and is billed at standard internet egress rates.

Answer

Inter-AD communication requires the manual setup of encrypted IPsec VPN connections.

Answer

Availability domains are not connected directly; all communication must route through a secondary OCI region.

Question 11

An administrator wants to ensure that all Audit log events in the tenancy are archived to an Object Storage bucket for long-term retention and compliance. How should this be configured?

Accepted Answer

Configure Audit Log Configuration in the OCI Console to export logs to an Object Storage bucket.. OCI Audit provides an archival feature where you can configure a retention period and point Audit logs to an Object Storage bucket for long-term preservation.

Answer

Create a Cloud Guard detector recipe for log archiving.

Answer

Write a custom Python script that polls the OCI Monitoring API every minute.

Answer

Attach a compartment quota to the audit compartment.

Question 12

Which TWO methods can be used to authenticate users accessing OCI services? (Choose two.)

Accepted Answer

API signing keys for CLI and SDK access. Users can authenticate via passwords/MFA in Identity Domains, API signing keys, auth tokens, or federated identity providers.

Answer

Secure Shell (SSH) key pairs stored in IAM policies

Answer

Shared tenancy root certificates

Answer

IAM compartment credentials

Question 13

An organization is building a hybrid cloud strategy and evaluates OCI's cloud models. They want to run Oracle Database workloads on Exadata infrastructure inside their own data center, managed through the OCI console, with infrastructure maintenance performed by Oracle.
