NEW QUESTION # 41
By default, OCI IAM policies follow the principle of least privilege. What does this principle mean in the context of policy creation?

A. Policies should provide only the minimum set of permissions required for users to perform their tasks effectively.
B. Policies should be identical for all users within a tenancy.
C. Policies should grant all possible permissions to simplify access control.
D. Policies should be written in a complex and technical manner to enhance security.

Answer: A

Explanation:
The principle of least privilege is a security best practice that dictates that users should only be granted the minimum set of permissions necessary to perform their tasks. This principle helps to minimize the risk of accidental or malicious actions that could compromise security.
IAM Policies in OCI: When creating IAM policies in OCI, you should carefully evaluate the required permissions and only grant those that are absolutely necessary for the users or groups to perform their specific roles. This helps to reduce the attack surface and prevent unauthorized access to sensitive resources.

NEW QUESTION # 42
You can attach resources to a Dynamic Routing Gateway (DRG). Select THREE of these resources.

A. Virtual Circuits
B. IPSec Tunnel
C. VNIC
D. Local Peering Connection
E. Subnet
F. Remote Peering Connections

Answer: A,B,F

Explanation:
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.

NEW QUESTION # 43
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. 2.5 GB
B. 1 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 # 44
Which TWO options will accomplish a fully redundant connection from an on-premises data center to a Virtual Cloud Network (VCN) in the us-ashburn-1 region?

A. Configure one FastConnect virtual circuit to the us-ashburn-1 region and the second FastConnect virtual circuit to the us-phoenix-1 region.
B. Configure a Site-to-Site VPN from a single on-premises CPE.
C. Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the us-ashburn-1 region.
D. Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.

Answer: C,D

Explanation:
For a fully redundant connection from an on-premises data center to a VCN in the OCI us-ashburn-1 region, it is important to ensure high availability and fault tolerance. Here's how each option contributes to redundancy:
Option B: Two FastConnect Virtual Circuits:
FastConnect provides a dedicated, private connection with higher bandwidth and more consistent performance compared to a VPN. To achieve redundancy, you can configure two FastConnect circuits in the same region (us-ashburn-1), each terminated on diverse hardware on-premises. This setup ensures that even if one circuit or its associated hardware fails, the other circuit can maintain the connection. This ensures no single point of failure in the connectivity to OCI. Thus, option B is correct.
Option D: FastConnect and Site-to-Site VPN:
Another approach to redundancy is to have a mix of connection types. By setting up one FastConnect circuit and one Site-to-Site VPN, both terminating in the same region (us-ashburn-1), you create a diverse connection path. If the FastConnect connection fails, traffic can automatically route through the VPN connection, maintaining connectivity. This setup adds an extra layer of redundancy, making option D correct as well.
Incorrect Options:
Option A: Only configuring a Site-to-Site VPN from a single on-premises CPE does not provide redundancy because it involves just one connection path. If that connection or the CPE fails, there would be no fallback.
Option C: Configuring FastConnect circuits to different regions (us-ashburn-1 and us-phoenix-1) does not provide redundancy within a single region but rather across regions, which is not required for regional redundancy.
Relevant OCI Documentation:
OCI FastConnect Overview
Using Site-to-Site VPN and FastConnect for Redundancy
These references offer more detailed information on setting up redundant connections and the benefits of each connection type within OCI.

NEW QUESTION # 45
How can OCI IAM be configured to facilitate cross-region access?

A. The administrator can grant users permissions to access specific resources in the other region.
B. Identity domain replication must be enabled.
C. The identity domain automatically replicates to the other region.
D. Users can access resources in all regions by default.

Answer: A

Explanation:
In Oracle Cloud Infrastructure (OCI), cross-region access is facilitated by configuring IAM policies that grant users or groups permissions to access resources in other regions. IAM policies in OCI are global, meaning they apply across all regions by default. However, an administrator can specifically configure these policies to allow or restrict access to resources in different regions.
Example: An administrator can write a policy that allows a user to manage compute instances in a specific region by including the region's name in the policy statement.
