Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q52-Q57):

NEW QUESTION # 52
Which Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policy is invalid?

A. Allow group 'Default'/'A-Admins' to manage all-resources in compartment Project-A
B. Allow any-user to inspect users in tenancy
C. Allow group 'Default'/'A-Developers' to create volumes in compartment Project-A
D. Allow dynamic-group 'Default'/'FrontEnd' to manage instance-family in compartment Project-A

Answer: B

Explanation:
In Oracle Cloud Infrastructure (OCI), Identity and Access Management (IAM) policies are used to control access to resources. The policy in option C is invalid because "any-user" is not a valid principal in OCI IAM policies. OCI policies can only grant permissions to groups or dynamic groups, but not to arbitrary users.
Here's an explanation for each option:
A . Allow dynamic-group 'Default'/'FrontEnd' to manage instance-family in compartment Project-A: This is valid. It grants the dynamic group 'FrontEnd' the ability to manage instances within the Project-A compartment.
B . Allow group 'Default'/'A-Admins' to manage all-resources in compartment Project-A: This is valid. It provides full administrative access to all resources in the Project-A compartment for the 'A-Admins' group.
C . Allow any-user to inspect users in tenancy: This is invalid because OCI does not allow the use of "any-user" in policies. You must specify a valid group or dynamic group to define permissions.
D . Allow group 'Default'/'A-Developers' to create volumes in compartment Project-A: This is valid. It permits the 'A-Developers' group to create volumes in the Project-A compartment.

NEW QUESTION # 53
What is the primary function of the Network Path Analyzer (NPA) tool provided by Oracle Cloud Infrastructure (OCI)?

A. Sending actual traffic between source and destination to diagnose connectivity issues
B. Providing real-time monitoring of network traffic to detect security threats and unauthorized access attempts
C. Collecting and analyzing network configuration to identify virtual network configuration issues impacting connectivity
D. Optimizing network performance by dynamically adjusting routing paths based on traffic patterns

Answer: C

Explanation:
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.

Oracle Cloud Infrastructure Documentation: Network Path Analyzer

NEW QUESTION # 54
Which compute capacity type would you select to meet these requirements?

A. Capacity reservation
B. On-demand capacity
C. Dedicated host
D. Preemptible capacity

Answer: B

Explanation:
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.
Reference:
Oracle Cloud Infrastructure Documentation: OCI Compute Pricing
Oracle Cloud Infrastructure Documentation: Compute Instance Lifecycle
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.

NEW QUESTION # 55
Which authentication option should you use to ensure third-party APIs communicate with OCI resources?

A. SSH Key Pair with 2048-bit algorithm
B. Auth Tokens
C. OCI Username and Password
D. API Signing Key

Answer: D

Explanation:
When ensuring that third-party APIs communicate securely with OCI resources, the appropriate authentication option is API Signing Key.
API Signing Key: This method uses an RSA key pair to authenticate and sign API requests. The API signing key provides a secure and reliable way to ensure that the API requests to OCI are coming from an authorized source. It is commonly used for programmatic access to OCI services.
Other Options:
SSH Key Pair: Primarily used for secure shell access to compute instances, not for API authentication.
Auth Tokens: Typically used for authentication in environments where APIs don't support the API Signing Key, such as OCI CLI or SDKs.
OCI Username and Password: Generally used for the Console login, not for securing API communications.
Relevant OCI Documentation:
API Signing Key Authentication
This documentation provides details on using API Signing Keys for secure API communication in OCI.

NEW QUESTION # 56
Which TWO statements about the Oracle Cloud Infrastructure (OCI) File Storage Service are accurate?

A. Customers can encrypt data in their file system using their own Vault encryption key.
B. Customers can encrypt the communication to a mount target via export options.
C. Communication with file systems in a mount target is encrypted via HTTPS.
D. File systems use Oracle-managed keys by default.

Answer: A,D

Explanation:
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.

Oracle Cloud Infrastructure Documentation: File Storage Encryption
