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.

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.

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.

Geolocation Steering in OCI's Traffic Management Steering Policy allows you to distribute DNS traffic based on the geographical location of the end users. This method helps direct users to the nearest regional endpoint, optimizing latency and improving user experience.

Use Cases: Geolocation Steering is commonly used to deliver region-specific content, comply with data residency laws, or optimize service performance by directing traffic to the closest available servers.

In OCI File Storage, snapshots are point-in-time, read-only copies of a file system that do not immediately consume additional storage beyond the space needed to track changes.

Incorrect Statement: The statement that a new snapshot consumes more storage even if nothing has changed is incorrect. Snapshots are space-efficient; they only consume additional storage as changes are made to the file system after the snapshot is taken. If no changes are made between snapshots, the storage consumption remains minimal.

Correct Statements:

B . Before cloning a file system, at least one snapshot must exist, as the clone operation relies on this snapshot to create a copy.

C . Snapshots are accessible under the .snapshot directory, allowing users to view and restore files from specific snapshots.

D . Snapshots provide a consistent, point-in-time view of the file system, ensuring data integrity.
