Oracle Cloud Infrastructure 2025 Architect Associate Sample Questions (Q40-Q45):NEW QUESTION # 40
How can an organization securely grant a third-party application access to specific OCI resources?
  • A. By creating an IAM policy granting full access to the tenancy
  • B. By implementing OAuth 2.0 with the application
  • C. By sharing user credentials for an OCI administrator
  • D. By configuring the application to utilize Instance Principal
Answer: D
Explanation:
To securely grant a third-party application access to specific Oracle Cloud Infrastructure (OCI) resources, the recommended approach is to configure the application to use Instance Principal. This method allows the application to authenticate directly with OCI services without needing to manage sensitive credentials like passwords or API keys.
Instance Principals: Enable compute instances to directly make API calls against OCI services, inheriting permissions through IAM policies. This setup is more secure than sharing user credentials, as it avoids hardcoding credentials within the application and leverages OCI's native security features.

NEW QUESTION # 41
What is a key advantage of utilizing administrator roles for access control within OCI IAM identity domains?
  • A. Can be used to grant access to resources outside the identity domain
  • B. Simplify access management by eliminating policy creation
  • C. Offer a wider range of permission combinations
  • D. Provide granular control over user access to specific compartments
Answer: B
Explanation:
In Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM), administrator roles play a significant role in managing access:
Simplification of Access Management: Utilizing administrator roles allows you to simplify access management by eliminating the need to create complex IAM policies manually. These roles come with predefined permissions that cover common administrative tasks, reducing the effort needed to manage access controls.
Granular Control: While administrator roles provide a broad range of permissions, they may not offer the same level of granularity as custom policies.
Other Benefits:
Offer a wider range of permission combinations (A): While custom policies can offer more specific combinations, administrator roles are designed to cover a broad range of tasks.
Granting Access Outside Identity Domain (C): Administrator roles are generally scoped to their identity domain and do not provide cross-domain access.
Granular Control (D): Although administrator roles simplify management, custom policies are typically used when granular control over specific compartments or resources is needed.
Relevant OCI Documentation:
OCI IAM Roles Overview
This resource provides detailed information on how roles and policies are used in OCI to manage access.

NEW QUESTION # 42
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
  • A. Each VNIC can only have one private IP address.
  • B. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
  • C. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
  • D. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
Answer: C,D
Explanation:
In Oracle Cloud Infrastructure (OCI), understanding how private IP addresses work is crucial for configuring network interfaces and managing instances within your Virtual Cloud Network (VCN).
Primary VNIC and Private IP Address:
When an instance is launched in OCI, it is attached to a Virtual Network Interface Card (VNIC). The primary VNIC, which is automatically created during the instance launch, is associated with a primary private IP address by default. This private IP address is essential for the instance to communicate within the VCN. The primary private IP address is automatically assigned and cannot be removed from the primary VNIC while the instance is running. This supports the statement C.
Additional Private IPs:
Contrary to statement B, each VNIC can indeed have multiple private IP addresses, but by default, the primary VNIC comes with only one primary private IP. You can manually add secondary private IPs if needed. However, the additional IPs are not assigned by default; hence, A is incorrect.
Public IP Association:
For instances requiring internet access, a public IP address can be optionally assigned to the private IP address if the instance is in a public subnet. This is critical for scenarios where an instance needs to communicate with the internet or external networks. This aligns with statement D.
Relevant OCI Documentation:
Oracle Cloud Infrastructure Networking Overview
VNICs and Private IPs
These references provide additional context and detail on how private IP addresses work within OCI and clarify the correct statements.

NEW QUESTION # 43
Which statement is true about pre-authenticated requests?
  • A. You need to provide your OCI credentials to the partner company.
  • B. Deleting a pre-authenticated request does not revoke access.
  • C. You cannot edit a pre-authenticated request.
  • D. Pre-authenticated requests can be used to delete buckets.
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), pre-authenticated requests (PARs) allow users to grant access to specific objects in Object Storage without requiring the recipient to have an OCI account or credentials. This feature is useful for sharing objects securely without exposing broader access.
Cannot Edit a PAR: Once a pre-authenticated request is created, you cannot edit it. If you need to change the settings, such as the expiration date or the object being shared, you must delete the existing PAR and create a new one.
Other Statements:
Deleting a PAR does indeed revoke access immediately, contradicting option B.
Providing OCI credentials (C) is not required for using PARs. The purpose of PARs is to avoid sharing credentials.
Deleting Buckets (D): PARs are designed for accessing objects, not for administrative actions like deleting buckets.
Relevant OCI Documentation:
Managing Pre-Authenticated Requests
This reference outlines the features and limitations of pre-authenticated requests, including the inability to edit them once created.

NEW QUESTION # 44
Which of the following is a valid RFC 1918 CIDR prefix that can be used for creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN)?
  • A. 10.0.0.0/8
  • B. 192.268.0.0/24
  • C. 192.168.0.0/16
  • D. 0.0.0.0/0
Answer: A,C
Explanation:
RFC 1918 defines IP address ranges that are reserved for private networks, which cannot be routed on the public internet. In Oracle Cloud Infrastructure (OCI), these private IP address ranges can be used to create Virtual Cloud Networks (VCNs). The valid RFC 1918 CIDR prefixes include:
192.168.0.0/16: A private IP range often used in home networks.
10.0.0.0/8: A large private IP range commonly used in enterprise networks.
Invalid Options:
B . 0.0.0.0/0: This CIDR represents all IP addresses and is not a valid private IP range.
C . 192.268.0.0/24: This is not a valid IP address range as the octet "268" is outside the allowable range of 0-255.
