1. 1What distinguishes a multicloud architecture in Oracle's multicloud framework?

   1. A.Coordinated use of services from multiple public cloud providersCorrect answer: A
   2. B.Use of multiple regions from a single cloud provider
   3. C.Use of multiple availability zones from a single cloud provider
   4. D.Use of private data centers with no public cloud services

   Explanation: Oracle states: "Multicloud architectures leverage the coordinated use of cloud services from two or more public cloud vendors." Multiple regions or zones of one provider do not meet that definition.

2. 2Where does Exadata infrastructure physically reside in the Oracle AI Database@AWS child-site model?

   1. A.In an AWS edge location outside a region
   2. B.In the customer's on-premises data center
   3. C.In an OCI availability domain outside AWS
   4. D.In an AWS data center within an availability zoneCorrect answer: D

   Explanation: Oracle states that the infrastructure "physically resides in an AWS data center (an AZ within an AWS region)" while it is logically mapped to OCI.

3. 3Which subnet CIDR is required when creating either an Exadata VM cluster or an Autonomous VM cluster on an ODB network?

   1. A.A backup subnet CIDR only
   2. B.A client subnet CIDRCorrect answer: B
   3. C.An application VPC subnet CIDR only
   4. D.A transit gateway subnet CIDR only

   Explanation: Oracle states: "The ODB network requires a client subnet CIDR for Exadata VM Cluster and Autonomous VM Cluster creation." A backup subnet is additionally required for Exadata VM clusters.

4. 4After creating an ODB network, which of its client and backup subnet CIDR ranges can be modified?

   1. A.Neither the client nor the backup subnet CIDRCorrect answer: A
   2. B.Only the client subnet CIDR
   3. C.Only the backup subnet CIDR
   4. D.Both the client and backup subnet CIDRs

   Explanation: AWS states: "You can't modify the client or backup subnet CIDR range for the ODB network after you create it." Both ranges therefore need planning before creation.

5. 5What is the role of Zero Downtime Migration (ZDM) in an Oracle Database@AWS migration?

   1. A.Orchestrate online or offline migration using underlying database toolsCorrect answer: A
   2. B.Perform only online migration through GoldenGate
   3. C.Orchestrate only migrations between identical platforms and versions
   4. D.Perform only offline migration through RMAN

   Explanation: Oracle describes ZDM as "Orchestrates both online and offline migrations using RMAN, Data Guard, or Data Pump." It also supports migrations across different database platforms and versions.

6. 6An architect needs an up-to-date standby database in a different AWS availability zone for a Database@AWS workload. Which design provides the documented cross-zone database redundancy?

   1. A.Use Active Data Guard to replicate to a standby database in the other zone.Correct answer: A
   2. B.Create an independent database in the other zone and copy data once with Data Pump.
   3. C.Maintain weekly cross-zone exports without ongoing database replication.
   4. D.Run independent databases in both zones without synchronizing their changes.

   Explanation: For the documented design Oracle says "To achieve availability zone redundancy for the database, use Oracle Active Data Guard in synchronous mode to replicate the database across availability zones." A single-zone cluster does not add zone separation.

7. 7An enterprise wants authorized administrators to use existing enterprise credentials when accessing the OCI tenancy linked to Oracle AI Database@AWS. What should it configure?

   1. A.Federate OCI with a different identity provider rather than the enterprise provider.
   2. B.Identity federation with the enterprise identity providerCorrect answer: B
   3. C.Create standalone OCI user passwords without linking the enterprise identity provider.
   4. D.Configure AWS IAM roles without federating the linked OCI tenancy.

   Explanation: Oracle says federation allows users "to sign in to the OCI tenancy associated with their existing Identity provider." The setup is optional and access remains subject to permissions.

8. 8An organization wants to use distinctive services offered by different cloud vendors. Which multicloud benefit addresses this objective?

   1. A.Improving availability across regions
   2. B.Applying different providers' pricing models
   3. C.Reducing exposure to a single-provider outage
   4. D.Using the capabilities of each selected providerCorrect answer: D

   Explanation: Oracle lists "Maximize on the capabilities of each provider" as a multicloud benefit. The requirement is to use distinctive provider capabilities rather than focus on availability, outage risk, or pricing.

9. 9What is an OCI child site in the Oracle AI Database@AWS architecture?

   1. A.A separate OCI region independent of the paired parent site
   2. B.A customer data center extending an OCI availability domain on premises
   3. C.A data center extending an OCI availability domain to an AWS availability zoneCorrect answer: C
   4. D.A data center extending an AWS availability zone into an OCI parent region

   Explanation: Oracle defines an OCI child site as "a data center that extends an OCI availability domain (AD) to an Availability Zone (AZ) in an AWS region." It is an extension of OCI into AWS, not a separate parent region or an on-premises installation.

10. 10A network designer needs the smallest permitted ODB client subnet. Which CIDR prefix should be selected?

    1. A./27Correct answer: A
    2. B./30
    3. C./28
    4. D./25

    Explanation: Oracle says "The minimum CIDR size for the client subnet is /27". A /25 is larger, while /28 and /30 contain fewer addresses.
