NEW QUESTION # 13
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
- A. By default, the primary VNIC of an instance in a subnet has one primary 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. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
- D. Each VNIC can only have one private IP address.
Answer: A,C
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.

NEW QUESTION # 14
Which statement accurately describes ephemeral principals?
- A. Ephemeral principals are temporary credentials granted to resources.
- B. Ephemeral principals represent long-lived service accounts.
- C. Ephemeral principals are another term for dynamic groups.
- D. Ephemeral principals are user accounts with limited lifespans.
Answer: A
Explanation:
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.

NEW QUESTION # 18
Which components are required for establishing remote peering between two Virtual Cloud Networks (VCNs) in Oracle Cloud Infrastructure (OCI)?
- A. A single VCN with nonoverlapping CIDRS in each region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGS.
- B. Two VCNs with overlapping CIDRS in different regions, a virtual private network (VPN) gateway attached to each VCN, and a direct connection between the VPN gateways.
- C. Two VCNs with nonoverlapping CIDRS in different regions, a dynamic routing gateway (DRG) attached to each VCN, a remote peering connection (RPC) on each DRG, and a connection established between the RPCs.
- D. Two VCNs with nonoverlapping CIDRS in the same region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGs.
Answer: C
Explanation:
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.

NEW QUESTION # 23
What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete when you overwrite 0.5 GB of a 1 GB file?
- A. 1 GB
- B. 2.5 GB
- C. 0.5 GB
- D. 1.5 GB
Answer: D
Explanation:
In Oracle Cloud Infrastructure (OCI) File Storage, when you overwrite a portion of a file, the service does not immediately reclaim the space occupied by the previous version of the file. The total meteredBytes reflects both the original data and the new data written.
Scenario Explanation: You start with a 1 GB file. When you overwrite 0.5 GB of this file, the file system retains both the 0.5 GB of the original file and the new 0.5 GB you wrote.
Calculation: The original 1 GB file contributes 1 GB to meteredBytes. When 0.5 GB is overwritten, the total usage becomes 1.5 GB (1 GB original + 0.5 GB new).
Thus, after the hourly update cycle, the total meteredBytes shown by the File Storage service will be 1.5 GB.

NEW QUESTION # 28
How can an organization securely grant a third-party application access to specific OCI resources?
- A. By configuring the application to utilize Instance Principal
- B. By implementing OAuth 2.0 with the application
- C. By sharing user credentials for an OCI administrator
- D. By creating an IAM policy granting full access to the tenancy
Answer: A
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.
Reference:
Oracle Cloud Infrastructure Documentation: Instance Principals
NEW QUESTION # 29
Which statement is true about pre-authenticated requests?
- A. You cannot edit a pre-authenticated request.
- B. You need to provide your OCI credentials to the partner company.
- C. Pre-authenticated requests can be used to delete buckets.
- D. Deleting a pre-authenticated request does not revoke access.
Answer: A
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:

Which policy would you write to provide admin access to all three of your existing admin groups for a shared Test compartment?
- A. Allow group any-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- B. Allow dynamic-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- C. Allow all-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
- D. Allow any-user to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), policies are written to define permissions for user groups. The correct policy to provide admin access to all three existing admin groups in a shared compartment (in this case, the "Test" compartment) would be:
"Allow all-group to manage all-resources in compartment Test where request.principal.group.tag.EmployeeGroup.Role='Admin'".
"Allow all-group": Grants access to all groups.
"to manage all-resources": Specifies full access permissions (manage includes all CRUD operations).
"in compartment Test": Limits the scope of the policy to the "Test" compartment.
"where request.principal.group.tag.EmployeeGroup.Role='Admin'": Adds a condition to restrict this admin-level access to only groups tagged with the role 'Admin'.
This policy ensures that only users in the groups tagged as Admin will be allowed to manage resources in the Test compartment, making it the most suitable choice for providing admin access.
