1Z0-1085-26 Getting Started With Oci Practice Test 1 — 15 Questions

Question 1

A multinational corporation requires low-latency access for users in Frankfurt and London, with strict data isolation ensuring European data does not leave designated jurisdictions. Which OCI architectural construct should you use to organize their resources?

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

Accepted Answer

OCI Regions. OCI Regions are geographic areas that contain one or more Availability Domains. To provide low-latency access to users in Frankfurt and London while ensuring data isolation within European jurisdictions, you would deploy resources in the Frankfurt and London regions (or a single region if data can be replicated within the EU). Regions are the primary construct for geographic distribution and data residency compliance.

Answer

Compartments

Answer

Availability Domains

Answer

Fault Domains

Question 2

An enterprise customer requires strict residency compliance where all data, including backups and metadata, must remain within their on-premises data center, but they still want native OCI cloud services and API parity. Which OCI deployment model should you recommend?

OCI FastConnect

Question 4

Your application requires 99.99% uptime. You decide to deploy instances across three Fault Domains (FD-1, FD-2, FD-3) within Availability Domain 1. When launching a new compute instance, what happens if you do not explicitly specify a Fault Domain?

Accepted Answer

OCI automatically assigns the instance to a Fault Domain using a load-balancing algorithm that distributes instances evenly across all available Fault Domains.. If no fault domain is specified, OCI automatically distributes instances evenly across the available fault domains using a round-robin approach.

Answer

The instance is placed in a default scratchpad fault domain and must be manually moved later.

Answer

OCI places the instance in Fault Domain 1 by default every time.

Answer

The instance fails to launch until a Fault Domain is explicitly provided in the API request.

Question 5

An organization must comply with strict data sovereignty laws requiring that their cloud environment remain physically isolated from the public internet and operated independently, yet still receive continuous updates and feature parity with OCI public cloud. Which deployment model satisfies this requirement?

Accepted Answer

OCI Dedicated Region. OCI Dedicated Region delivers a complete OCI region deployed inside the customer's own data center, giving full physical isolation from the public internet while Oracle retains operational responsibility for patching and upgrades. Because Oracle manages the infrastructure, customers receive continuous updates and feature parity with the OCI public cloud. This uniquely satisfies the combination of sovereignty, isolation, and parity required by the scenario.

Answer

OCI Hybrid Cloud via VPN Connect.

Answer

OCI FastConnect with a dedicated private circuit.

Answer

OCI Public Cloud with a dedicated Virtual Cloud Network (VCN).

Question 6

An enterprise customer wants to leverage OCI Compute Cloud@Customer to run containerized microservices on-premises while integrating seamlessly with OCI public cloud management tools. How does Compute Cloud@Customer achieve this integration?

Accepted Answer

By running an autonomous Kubernetes control plane locally that synchronizes with public cloud APIs via a secure management connection.. Compute Cloud@Customer runs an autonomous Kubernetes control plane locally on the on-premises rack and synchronizes with OCI public cloud APIs through a secure management connection. This allows customers to use OCI management tools and APIs while keeping compute workloads on-premises.

Answer

By replicating all public cloud control plane services locally onto every customer node.

Answer

By requiring manual exports of cloud templates and uploading them via Secure Shell (SSH) daily.

Answer

By converting the on-premises rack into a public OCI Region accessible via the public internet.

Question 7

When designing a disaster recovery plan utilizing multiple OCI regions, which THREE factors must an architect consider? (Choose three.)

Accepted Answer

Configuring automated DNS or traffic management failover to redirect users during an outage.. Cross-region DR planning involves RPO/RTO metrics, data replication mechanisms, and automated traffic failover.

Answer

Physically shipping backup tapes between regional data centers on a weekly basis.

Answer

Ensuring that all availability domains across both regions share the exact same fault domain naming convention.

Question 8

Which TWO statements are true regarding OCI Regions and their global naming conventions or structure? (Choose two.)

Accepted Answer

OCI regions are deployed worldwide to provide low-latency access and meet data residency regulations.. OCI regions have distinct identifiers/key names and are geographically distributed.

Answer

An OCI region can span across multiple continents simultaneously.

Answer

All OCI regions share the same Availability Domain identifiers globally.

Answer

OCI regions are managed by individual third-party cloud providers in each country.

Question 9

An enterprise customer requires strict residency and data sovereignty within their own physical data center, yet demands full compatibility with standard OCI cloud services and APIs. Which OCI deployment model best fits this requirement?

Question 10

Your development team needs to deploy a multi-tier web application in OCI. To guarantee maximum high availability against unexpected power failures and cooling outages within a single data center facility, how should the application instances be distributed?

Accepted Answer

Place instances across multiple availability domains.. High availability within a region is achieved by spreading workloads across multiple availability domains.

Answer

Place all instances in the same fault domain.

Answer

Assign all instances to the root compartment.

Answer

Deploy all instances across different global regions.

Question 11

An organization is evaluating the OCI distributed cloud model and requires an environment that is completely managed and operated by Oracle, yet deployed within the customer's own building to meet stringent data residency regulations. Which product meets this?

Accepted Answer

Question 12

When you create a compute instance in an OCI region that has three availability domains, and you do not explicitly specify an availability domain or fault domain, how does OCI handle the placement?

Accepted Answer

OCI automatically distributes the instance across availability domains and fault domains for high availability.. If not specified, OCI automatically selects an availability domain and distributes instances across fault domains to ensure high availability.

Answer

OCI places it in the first availability domain and fault domain by default every time.

Answer

Creation fails until you explicitly choose a fault domain.

Answer

The instance is created in a paused state until placement is manually resolved.

Question 13

Which THREE characteristics apply to OCI Fault Domains? (Choose three.)

Accepted Answer

Each availability domain contains three fault domains by default.. Fault domains are chosen during instance creation (or assigned automatically), provide anti-affinity, and reside within an availability domain.

Answer

Fault domains span across multiple availability domains.

Answer

Fault domains require separate network subscriptions for each domain.

Question 14

When designing a highly available web application on OCI, an architect wants to ensure that if a fiber-optic cable is accidentally cut leading into one specific data center facility, user traffic can automatically fail over to a completely independent facility within the same metropolitan area. What should the architect use?

Accepted Answer

Multiple Availability Domains. Availability Domains are designed to be fault-tolerant with independent power, cooling, and network infrastructure, meaning they do not share infrastructure dependencies.

Answer
