NEW QUESTION # 17
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 and one secondary private IP address.
- B. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
- C. Each VNIC can only have one private IP address.
- D. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
Answer: B,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 statementC.
* 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, Ais 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 statementD.
* 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 # 19
Which statement is TRUE about delegating an existing domain to the Oracle Cloud Infrastructure (OCI) DNS service?
- A. All domains can be retrieved to OCI DNS via DYN.
- B. Domains can be delegated to OCI DNS via FastConnect partners.
- C. Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal.
- D. Domains can be self-delegated to OCI DNS from its own service portal.
Answer: C
Explanation:
To delegate a domain to the Oracle Cloud Infrastructure (OCI) DNS service, the domain needs to be pointed to OCI's DNS servers. This can be done through the Domain Registrar's self-service portal, where you update the name servers for your domain to OCI's DNS servers.
* Process:You typically log into the domain registrar where your domain is registered and replace the existing name servers with the name servers provided by OCI DNS. Once this is done, DNS queries for your domain will be directed to OCI DNS.

NEW QUESTION # 20
Which statement is NOT true about the Oracle Cloud Infrastructure (OCI) Object Storage service?
- A. Object lifecycle rules can be used to archive or delete objects.
- B. Object Versioning is enabled at the namespace level.
- C. Immutable option for data stored in Object Storage can be set via retention rules.
- D. Object Storage resources can be shared across tenancies.
Answer: D
Explanation:
Oracle Cloud Infrastructure (OCI) Object Storage is a scalable, highly durable service that allows you to store any type of data in a secure and cost-effective manner. The correct and incorrect statements regarding OCI Object Storage are as follows:
* A. Immutable Option: You can indeed set an immutable option for data in Object Storage using retention rules. This feature ensures that once data is written, it cannot be modified or deleted until the retention period expires, making it ideal for regulatory compliance.
* C. Object Lifecycle Rules: Object lifecycle policies allow you to automate the archiving or deletion of objects based on their age or other criteria, helping manage storage costs and data retention efficiently.
* D. Object Versioning: Versioning is enabled at the bucket level, not the namespace level. However, once enabled for a bucket, it helps retain, retrieve, and restore every version of every object stored in that bucket.
* B. Object Storage Sharing Across Tenancies: This statement isnot true. OCI Object Storage buckets and objects are specific to a tenancy and cannot be shared across different tenancies directly. Access to Object Storage resources is controlled within a single tenancy through IAM policies.
* Relevant OCI Documentation:
* OCI Object Storage Overview
* Object Lifecycle Management
These references provide details on how Object Storage functions and the features available.
NEW QUESTION # 21
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OCI) File System snapshots?
- A. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
- B. Snapshots are a consistent, point-in-time view of your file systems.
- C. Snapshots are accessible under the root directory of the file system at .snapshot/name.
- D. Before you can clone a file system, at least one snapshot must exist for the file system.
Answer: A
Explanation:
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 isincorrect. 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.snapshotdirectory, 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.
