NEW QUESTION # 38
How will moving a database instance to a different compartment impact user access?
- A. IAM policies are not tied to compartments.
- B. Compartments prevent resource movement.
- C. Access will be revoked for all users.
- D. Compartments are not covered by IAM policies.
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), when you move a database instance to a different compartment, the following impact on user access occurs:
Impact of Moving Resources: When you move a resource, like a database instance, to a different compartment, the IAM policies that grant access to that resource in the original compartment no longer apply. This effectively revokes access for users or groups unless equivalent policies are in place in the new compartment.
Restoring Access: To restore access, you would need to create new IAM policies in the destination compartment that grant the necessary permissions to the users or groups who need access.

Moving Resources
These resources provide detailed steps on how compartment changes impact resource access and management.
NEW QUESTION # 39
Which TWO are key benefits of setting up Site-to-Site VPN on Oracle Cloud Infrastructure (OCI)?
- A. When setting up Site-to-Site VPN, customers can configure it to use static or dynamic routing (BGP).
- B. When setting up Site-to-Site VPN, it creates a private connection that provides consistent network experience.
- C. When setting up Site-to-Site VPN, customers can expect bandwidth above 2 Gbps.
- D. When setting up Site-to-Site VPN, OCI provisions redundant VPN tunnels.
Answer: A,D
Explanation:
Setting up a Site-to-Site VPN on Oracle Cloud Infrastructure offers several key benefits related to connectivity and reliability:
Static or Dynamic Routing (BGP): OCI allows customers to configure Site-to-Site VPN with either static routing or dynamic routing using Border Gateway Protocol (BGP). This flexibility enables customers to choose the routing method that best suits their network configuration and requirements.
Redundant VPN Tunnels: OCI automatically provisions redundant VPN tunnels when you set up a Site-to-Site VPN. These redundant tunnels ensure high availability and fault tolerance, so if one tunnel fails, traffic can continue to flow through the other tunnel without interruption.
Bandwidth Considerations: While the VPN provides a reliable connection, it typically does not exceed 2 Gbps in bandwidth. Higher bandwidth connections usually require FastConnect.
Private Connection: The VPN does create a secure and private connection between on-premises data centers and OCI, but it does not inherently provide a consistent network experience in the way that a dedicated connection like FastConnect does.
Relevant OCI Documentation:
Site-to-Site VPN Overview
Configuring Routing for VPNs
These references detail the benefits and technical specifications of setting up Site-to-Site VPNs on OCI.
NEW QUESTION # 40
Why was SSH still possible after port 22 was removed from the Security Lists?
- A. The VCN where that compute instance resides still has an Internet Gateway.
- B. The VCN where that compute instance resides still has a route rule.
- C. The VNIC of that compute instance is attached to a Network Security Group (NSG).
- D. The VNIC of that compute instance is attached to a Cluster Network.
Answer: C
Explanation:
Even after removing port 22 from the Security Lists, SSH was still possible because the Virtual Network Interface Card (VNIC) of the compute instance is attached to a Network Security Group (NSG).
NSGs: NSGs provide a more flexible and granular way to manage security rules compared to Security Lists. They allow you to apply security rules directly to VNICs associated with resources such as compute instances. If an NSG allows traffic on port 22, SSH will still be possible, regardless of the Security List settings.
