Oracle 1Z0-1072-25 Exam Questions

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.

On-demand capacity is the compute capacity type in Oracle Cloud Infrastructure (OCI) that allows you to provision and use compute instances whenever needed, without any long-term commitment. This flexibility is ideal for various workloads, including development, testing, and production environments, where immediate availability and scalability are crucial.

Key Points:

On-Demand Capacity: On-demand compute instances provide users with the flexibility to spin up instances as required and only pay for the time the instances are running. This model is most suitable for workloads with unpredictable usage patterns or short-term requirements.

Flexibility and Scalability: With on-demand capacity, you can quickly scale your resources up or down based on your application's needs, ensuring that you only pay for the resources you actually use.

No Commitment: Unlike reserved capacity, on-demand capacity does not require any long-term commitment or upfront payment, making it an attractive option for organizations looking to avoid capital expenditures.

Explanation of Incorrect Options:

A . Capacity reservation: This option allows you to reserve capacity in advance, ensuring that resources are available when needed. It's ideal for predictable workloads but may not be as cost-effective for fluctuating demands.

B . Preemptible capacity: Preemptible instances are a lower-cost option where instances can be terminated by OCI if resources are needed elsewhere. This is suitable for non-critical workloads that can tolerate interruptions.

D . Dedicated host: Dedicated hosts provide physical servers for your exclusive use, offering isolation and predictable performance. This option is more suitable for workloads requiring dedicated resources or compliance needs.

Thus, Option C: On-demand capacity is the correct choice for most general-purpose workloads needing flexibility and immediate availability without long-term commitment.

The primary function of the Network Path Analyzer (NPA) tool in Oracle Cloud Infrastructure (OCI) is to help users troubleshoot and diagnose network connectivity issues by analyzing the network path between a source and a destination within OCI. The tool collects and analyzes the configuration of the virtual network, identifying any misconfigurations or issues that might impact connectivity.

NPA Usage: The Network Path Analyzer allows administrators to trace the network path and check for issues such as incorrect security list rules, route table misconfigurations, or any other factors that could prevent network traffic from reaching its destination.

A Dynamic Routing Gateway (DRG) in Oracle Cloud Infrastructure (OCI) is a virtual router that provides a path for private traffic between your on-premises network and your VCN, or between your VCN and other VCNs. The resources that can be attached to a DRG include:

A . Virtual Circuits: Used to establish a private connection between your on-premises data center and your VCN via Oracle's FastConnect service.

D . Remote Peering Connections: Enables peering between VCNs located in different regions (Remote VCN Peering).

E . IPSec Tunnel: Facilitates secure VPN connections between your on-premises network and your OCI VCN.

To calculate the monthly cost for 7 Petabytes (PB) of outbound data transfer at a rate of $0.0085 per GB in North America:

Calculation:

1 PB = 1,000,000 GB

7 PB = 7,000,000 GB

Cost = 7,000,000 GB * $0.0085/GB = $59,500.00

Thus, the cost for 7 PB of outbound data transfer per month is $59,500.00.
