Free 1z0-1151-25: Oracle Cloud Infrastructure 2025 Multicloud Architect Professional Exam Questions and Answers
Oracle Cloud Infrastructure 2025 Multicloud Architect Professional is exam 1151-25, part of Oracle Certification from Oracle University. Oracle exam codes begin 1Z0-, and modern ones end in the release year, so 1Z0-1085-26 is the 2026 release of OCI Foundations Associate. The least-known rule is the update path: a Delta exam swaps the prefix to 1D0- and appends -D while keeping the same family number, so 1Z0-1058-26 renews through 1D0-1058-26-D.
If you searched for 1151-25 dumps, a 1151-25 ExamTopics discussion or a free 1151-25 PDF, this is the 1z0-1151-25: Oracle Cloud Infrastructure 2025 Multicloud Architect Professional question bank: practice questions with verified answers and explanations, a timed 1151-25 practice test and updates whenever Oracle changes the exam.

Question #1
Which VCN component lets instances in a private subnet initiate outbound connections to the internet while preventing connections that are initiated from the internet?
Correct answer: D
Explanation
A NAT gateway lets resources without public IP addresses start outbound connections and accepts only the return traffic. An internet gateway allows both inbound and outbound traffic for resources with public IPs. A service gateway reaches Oracle services privately, and a DRG connects the VCN to on-premises or other networks.

Question #2
A security policy requires that database hosts in a private subnet of an OCI VCN send backups to Object Storage without any traffic crossing the public internet. The hosts have no public IP addresses. Which configuration meets the requirement?
Correct answer: B
Explanation
A service gateway gives private access to Object Storage over the Oracle network fabric, provided the subnet route table sends the Oracle Services Network destination to it. A NAT gateway still reaches the service through the public internet path. An internet gateway needs public IPs, and a local peering gateway only connects two VCNs and does not expose Object Storage.

Question #3
A retailer runs a production Exadata VM cluster with Oracle Database@Azure in East US. The business requires protection from a full regional outage with a recovery point objective close to zero. Which should the architect configure?
Correct answer: D
Explanation
Data Guard continuously ships redo to a standby in another region, so a regional outage can be handled with a failover and almost no data loss. RAC protects against node failure inside one cluster, not a regional outage. Azure Site Recovery does not replicate Exadata infrastructure, and backups with archive log copies leave a larger recovery point gap.

Question #4
A database administrator needs more CPU capacity on an existing Exadata VM cluster in Oracle Database@Google Cloud before quarter-end processing. The Exadata infrastructure has unused capacity, and the databases must stay available. Which should the administrator do?
Correct answer: D
Explanation
CPU capacity of a VM cluster can be scaled from the capacity that remains available in the Exadata infrastructure, and the change is applied online without taking the databases down. Rebuilding on a new infrastructure is unnecessary and disruptive. The databases do not run on Compute Engine instances, and subnet size controls IP addresses, not CPU.

Question #5
An architect is creating an ExpressRoute circuit in the Azure portal for Oracle Interconnect for Azure. Which provider must be selected for the circuit?
Correct answer: C
Explanation
Azure lists Oracle Cloud FastConnect as the ExpressRoute service provider. The circuit's service key is then used to create the matching FastConnect virtual circuit in OCI. The other names are not ExpressRoute providers.

Question #6
Application VMs run in a Google Cloud VPC network. An architect must give them private access to an Exadata VM cluster in Oracle Database@Google Cloud. Which Google Cloud resource provides the client and backup subnets used by the VM cluster?
Correct answer: B
Explanation
An ODB network defines the client and backup subnets that the Exadata VM cluster uses, and it provides the private path to the VPC. A Cloud Router exchanges BGP routes and does not define VM cluster subnets. A Shared VPC host project and a Serverless VPC Access connector do not provide the VM cluster network.

Question #7
An administrator has accepted the Oracle Database@Google Cloud offer in Google Cloud Marketplace. Which onboarding step must be completed next in the Google Cloud console before Exadata resources can be created?
Correct answer: B
Explanation
After the offer is accepted, the Google Cloud project must be tied to an OCI account (tenancy), either by linking an existing one or by creating a new one. Oracle Database@Google Cloud runs inside Google Cloud data centers, so no Partner Interconnect connection is needed to onboard.

Question #8
An architect creates a Partner type VLAN attachment in Google Cloud and uses its pairing key to create a FastConnect virtual circuit in OCI. The virtual circuit shows as provisioned, but the BGP session between the Cloud Router and the OCI DRG never establishes. The Cloud Router was created with ASN 65001, and the DRG route configuration is correct. What is the MOST likely cause?
Correct answer: D
Explanation
Cloud Routers used with Partner Interconnect VLAN attachments must be created with Google's ASN 16550, so a Cloud Router using 65001 cannot bring up the BGP session. A provisioned virtual circuit only means the layer 2 path exists. The pairing key is generated by Google Cloud when the attachment is created, not by the VCN attachment.

Question #9
An administrator created Exadata infrastructure in the us-east4 region of Oracle Database@Google Cloud. When creating the Exadata VM cluster, the only ODB network available was created earlier in us-central1, and the console does not allow it to be selected. What should the administrator do?
Correct answer: B
Explanation
The ODB network used by a VM cluster must be in the same region as its Exadata infrastructure, so a new ODB network is needed in us-east4. VLAN attachments, VPC peering and Cloud Router routing settings do not change the region binding of the VM cluster network.

Question #10
When compute auto scaling is enabled for an Autonomous Database, up to how many times the base number of ECPUs can the database use automatically?
Correct answer: B
Explanation
With auto scaling enabled, an Autonomous Database can use up to three times the base ECPU count when the workload demands it, and scales back down when demand drops. Billing for the extra capacity applies only while it is used.
