Frequently Asked Questions

What topics carry the most weight on the 1Z0-1072-25 exam?

Compute and Networking typically account for a larger percentage of exam questions, as they form the foundation of most OCI architectures. However, all four domains, Compute, Networking, Storage, and Identity and Access Management, are equally important for designing production-ready solutions. Allocate study time proportionally but ensure you develop competency across all areas.

How do Compute, Networking, Storage, and Identity and Access Management work together in a real OCI project?

In practice, these domains are interconnected. Compute instances run on networks you design, store data in storage services you configure, and are accessed through IAM policies you enforce. A typical workflow involves creating a network topology, launching compute instances within that network, attaching storage volumes, and then restricting access via compartments and IAM policies. Understanding these dependencies helps you make holistic architectural decisions.

How much hands-on experience do I need, and which labs should I prioritize?

Hands-on experience significantly improves retention and confidence. Prioritize labs that cover creating and managing compute instances, configuring virtual cloud networks with security lists, provisioning block and object storage, and setting up IAM policies and compartments. Even if you have limited lab access, working through Oracle's free tier environment or practice scenarios in study materials will strengthen your ability to apply concepts under exam conditions.

What are common mistakes candidates make on this exam?

Frequent errors include misunderstanding the scope of IAM compartments, confusing security list rules with network security group behavior, selecting incorrect instance shapes for workload requirements, and overlooking cost optimization in architectural decisions. Many candidates also rush through scenario questions without fully analyzing all requirements. Read each question carefully, identify what the scenario is asking, and eliminate obviously incorrect options before selecting your answer.

What should I focus on during my final week of preparation?

In the final week, take at least one full-length timed practice test to assess readiness and identify weak spots. Review explanations for any missed questions, paying special attention to why you selected the wrong answer. Spend remaining time on targeted review of your lowest-scoring topic areas rather than re-reading entire study materials. Get adequate sleep the night before the exam to ensure mental clarity during the test.

Question No. 1

Which statement accurately describes ephemeral principals?

Show Answer Hide Answer
Correct Answer: A

Ephemeral principals in Oracle Cloud Infrastructure (OCI) refer to temporary security credentials granted to resources, such as compute instances, to enable them to interact with OCI services securely. These credentials have a limited lifespan and are typically used in situations where resources need to authenticate temporarily without the need for long-lived credentials.

Use Case: Ephemeral principals are often used for instance principals, allowing compute instances to make API calls without the need to manage long-term keys or credentials.

Question No. 2

Which TWO are key benefits of setting up Site-to-Site VPN on Oracle Cloud Infrastructure (OCI)?

Show Answer Hide Answer
Correct Answer: B, C

Setting up a Site-to-Site VPN on Oracle Cloud Infrastructure offers several key benefits related to connectivity and reliability:

Static or Dynamic Routing (BGP): OCI allows customers to configure Site-to-Site VPN with either static routing or dynamic routing using Border Gateway Protocol (BGP). This flexibility enables customers to choose the routing method that best suits their network configuration and requirements.

Redundant VPN Tunnels: OCI automatically provisions redundant VPN tunnels when you set up a Site-to-Site VPN. These redundant tunnels ensure high availability and fault tolerance, so if one tunnel fails, traffic can continue to flow through the other tunnel without interruption.

Bandwidth Considerations: While the VPN provides a reliable connection, it typically does not exceed 2 Gbps in bandwidth. Higher bandwidth connections usually require FastConnect.

Private Connection: The VPN does create a secure and private connection between on-premises data centers and OCI, but it does not inherently provide a consistent network experience in the way that a dedicated connection like FastConnect does.

Question No. 3

Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OCI) File System snapshots?

Show Answer Hide Answer
Correct Answer: A

In OCI File Storage, snapshots are point-in-time, read-only copies of a file system that do not immediately consume additional storage beyond the space needed to track changes.

Incorrect Statement: The statement that a new snapshot consumes more storage even if nothing has changed is incorrect. Snapshots are space-efficient; they only consume additional storage as changes are made to the file system after the snapshot is taken. If no changes are made between snapshots, the storage consumption remains minimal.

Correct Statements:

B . Before cloning a file system, at least one snapshot must exist, as the clone operation relies on this snapshot to create a copy.

C . Snapshots are accessible under the .snapshot directory, allowing users to view and restore files from specific snapshots.

D . Snapshots provide a consistent, point-in-time view of the file system, ensuring data integrity.

Question No. 4

Which components are required for establishing remote peering between two Virtual Cloud Networks (VCNs) in Oracle Cloud Infrastructure (OCI)?

Show Answer Hide Answer
Correct Answer: D

Remote peering in Oracle Cloud Infrastructure allows two VCNs in different regions to communicate securely. To establish remote peering, the following components are required:

Two VCNs with Nonoverlapping CIDRs:

The CIDR blocks of the two VCNs must not overlap. This is crucial to avoid routing conflicts and ensure that traffic is correctly routed between the VCNs.

Dynamic Routing Gateway (DRG) Attached to Each VCN:

A DRG is a virtual router that provides a path for traffic between the VCN and networks outside the VCN, such as other VCNs via remote peering, on-premises networks, or other cloud services. Each VCN needs its own DRG.

Remote Peering Connection (RPC):

An RPC is a specialized connection on the DRG used specifically for remote peering. You need to create an RPC on each DRG associated with the VCNs you wish to peer.

Connection Between RPCs:

Finally, a connection must be established between the RPCs of the two DRGs. This connection facilitates the secure and private exchange of traffic between the VCNs over Oracle's backbone network.

Incorrect Options:

Option A involves a single VCN, which does not fulfill the requirement of remote peering between two VCNs.

Option B involves overlapping CIDRs and VPN gateways, which are incorrect for remote peering.

Option C suggests peering within the same region, which would be considered local peering rather than remote peering.

These resources provide a detailed guide on configuring remote peering in OCI, ensuring secure and effective communication between VCNs across regions.


Question No. 5

Which TWO statements about the Oracle Cloud Infrastructure (OCI) File Storage Service are accurate?

Show Answer Hide Answer
Correct Answer: B, D

Oracle Cloud Infrastructure (OCI) File Storage Service offers robust encryption capabilities to ensure data security.

B . Customer-Managed Encryption: Customers can choose to encrypt their data using their own keys stored in the OCI Vault service. This gives customers control over their encryption keys and enhances data security.

D . Oracle-Managed Encryption: By default, all data stored in OCI File Storage is encrypted using Oracle-managed keys. This ensures that data is encrypted at rest without requiring any action from the customer.

Incorrect Statements:

A . Communication is not encrypted via HTTPS when accessing file systems; instead, encryption in transit is typically managed via NFS over TLS.

C . Encryption of communication to a mount target is handled via network configurations, not through export options.
