NEW QUESTION # 12
Which TWO statements are NOT correct regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
- A. Burstable instances cost less than regular instances.
- B. Burstable instances are charged according to the baseline OCPU.
- C. Baseline utilization is a fraction of each CPU core.
- D. If the instance's average CPU utilization is below the baseline, it can burst above the baseline.
Answer: A,B
Explanation:
The following statements about OCI burstable instances areNOT correct:
* A. Burstable instances cost less than regular instances:This is incorrect because burstable instances are not necessarily cheaper; the cost depends on the baseline utilization. While they allow for cost efficiency when running at a lower CPU baseline, they can become more expensive if frequently bursting above the baseline.
* B. Burstable instances are charged according to the baseline OCPU:This is incorrect because burstable instances are billed based on actual OCPU usage, which includes both baseline and burst usage. If an instance frequently operates above its baseline, the cost will reflect this higher usage.
Correct Concepts:
* C.Burstable instances can temporarily use more CPU than their baseline if the average CPU utilization is below the baseline.
* D.Baseline utilization is a fraction of each CPU core, which determines the level of consistent performance available without bursting.

NEW QUESTION # 15
Which Traffic Management Steering Policy facilitates the distribution of DNS traffic based on the geographical location of end users?
- A. Proximity Steering
- B. IP Prefix Steering
- C. Geolocation Steering
- D. ASN Steering
Answer: C
Explanation:
Geolocation Steeringin 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.

NEW QUESTION # 19
Which is NOT a valid action within the Oracle Cloud Infrastructure (OCI) Block Volume service?
- A. Restoring from a volume backup to a larger volume.
- B. Cloning an existing volume to a new, larger volume.
- C. Attaching a block volume to an instance in a different availability domain.
- D. Expanding an existing volume in place with offline resizing.
Answer: C
NEW QUESTION # 20
How can OCI IAM be configured to facilitate cross-region access?
- A. The identity domain automatically replicates to the other region.
- B. Identity domain replication must be enabled.
- C. Users can access resources in all regions by default.
- D. The administrator can grant users permissions to access specific resources in the other region.
Answer: D
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.

NEW QUESTION # 21
Which OCI feature should be used to ensure that communication between database servers and OCI Object Storage is secure?
- A. Use a Service Gateway
- B. Use a NAT Gateway
- C. Use a VPN Gateway
- D. Use a Local Peering Gateway
Answer: A
Explanation:
To ensure secure communication between database servers and OCI Object Storage, you should use aService Gateway. A Service Gateway enables instances in your VCN to privately access OCI services like Object Storage without traversing the public internet.
* Security:The traffic between your database servers and Object Storage remains within the Oracle network, providing a secure and high-performance connection.

* Oracle Cloud Infrastructure Documentation:Service Gateway Overview
NEW QUESTION # 22
What are the two types of capture filters that can be created for network monitoring?
- A. VTAP capture filters and network capture filters
- B. Flow log capture filters and VTAP capture filters
- C. Flow control capture filters and traffic capture filters
- D. Flow log capture filters and packet capture filters
Answer: B
NEW QUESTION # 23
Which image option allows you to create identical instances with minimal effort?
- A. Use Oracle-provided images
- B. Select an image from the OCI Marketplace
- C. Bring your own image
- D. Create a custom image
Answer: D
NEW QUESTION # 24
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. By default, the primary VNIC of an instance in a subnet has one primary 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: B,C
NEW QUESTION # 25
How can OCI IAM be configured to facilitate cross-region access?
- A. The identity domain automatically replicates to the other region.
- B. Identity domain replication must be enabled.
- C. Users can access resources in all regions by default.
- D. The administrator can grant users permissions to access specific resources in the other region.
Answer: D
NEW QUESTION # 26
What happens to the performance level of a volume when it is detached from an instance?
- A. The performance level remains unchanged.
- B. The performance level is adjusted to Balanced.
- C. The performance level is adjusted to Lower Cost (0 VPUs/GB).
- D. The performance level is adjusted to Higher Performance.
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), when a block volume is detached from an instance, its performance level is automatically adjusted to the "Lower Cost" tier, which provides 0 VPUs (Volume Performance Units) per GB. This adjustment helps reduce costs when the block volume is not actively being used by a compute instance.
Key Points:
* Volume Performance Levels:OCI offers various performance tiers for block volumes, including
"Higher Performance," "Balanced," and "Lower Cost." These tiers determine the level of IOPS (Input
/Output Operations Per Second) and throughput available to the volume.
* Automatic Adjustment:When a block volume is detached from an instance, OCI automatically optimizes the cost by switching the volume to the "Lower Cost" performance tier. This tier offers minimal performance, suitable for data that is not actively accessed.
* Cost Management:This automatic adjustment is beneficial for managing costs, as it prevents users from incurring unnecessary charges for higher performance levels when the volume is not in use.

* Oracle Cloud Infrastructure Documentation:Block Volume Performance Levels
NEW QUESTION # 27
What is the primary purpose of the Web Application Acceleration service offered by Oracle Cloud Infrastructure (OCI)?
- A. Monitoring and analyzing HTTP traffic patterns
- B. Speeding up traffic on layer 7 HTTP load balancers
- C. Improving the reliability of layer 7 HTTP load balancers
- D. Encrypting HTTP traffic
Answer: B
NEW QUESTION # 28
You enabled Cross Region Replication for the volume and selected US West (San Jose) as the destination region. What should you do to create a new volume from the volume replica?
- A. Trigger the replica.
- B. Initiate the replica.
- C. No action required. By default, the replica is available as a block volume.
- D. Activate the replica.
Answer: C
Explanation:
When Cross-Region Replication is enabled for a block volume in Oracle Cloud Infrastructure (OCI), the replication process automatically creates and maintains a synchronized copy of the block volume in the selected destination region (in this case, US West (San Jose)).
* Replica Availability: The replicated volume is immediately available as a block volume in the destination region. You do not need to take any additional action to activate or trigger the replica.
* Creating New Volumes: Since the replica is automatically available as a block volume, you can directly use it to create a new volume in the destination region without any manual intervention.
* Relevant OCI Documentation:
* Cross-Region Block Volume Replication
This documentation outlines how cross-region replication works and confirms that no additional steps are needed to create a new volume from a replica
