NEW QUESTION # 27
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 be written in a complex and technical manner to enhance security.
- B. Policies should provide only the minimum set of permissions required for users to perform their tasks effectively.
- C. Policies should grant all possible permissions to simplify access control.
- D. Policies should be identical for all users within a tenancy.
Answer: B
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 # 28
Which TWO statements are NOT correct regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
- A. Burstable instances are charged according to the baseline OCPU.
- B. Baseline utilization is a fraction of each CPU core.
- C. If the instance's average CPU utilization is below the baseline, it can burst above the baseline.
- D. Burstable instances cost less than regular instances.
Answer: A,D
Explanation:
The following statements about OCI burstable instances are NOT 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 # 31
A financial firm is designing an application architecture for its online trading platform that should have high availability and fault tolerance. What should the architect do to avoid any costly service disruptions and ensure data durability?
- A. Copy the Object Storage bucket to a block volume.
- B. Create a new Object Storage bucket in another region and configure recycle policy to move data every 5 days.
- C. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
- D. Create a replication policy to send data to a different bucket in another OCI region.
Answer: D
Explanation:
For an online trading platform requiring high availability and fault tolerance, it's critical to ensure data durability and avoid any costly service disruptions. In Oracle Cloud Infrastructure (OCI), Object Storage is often used to store critical data, such as transaction logs or user data, due to its scalability, durability, and reliability.
Option B is the most suitable approach for ensuring data durability and availability across regions. Here's why:
Cross-Region Replication (CRR): OCI offers a feature called Cross-Region Replication for Object Storage. This feature allows you to automatically and asynchronously replicate objects in a bucket from one OCI region to another. This setup ensures that even if one region experiences a failure, the data is still available in another region, thereby meeting the requirements for high availability and fault tolerance.
Data Durability: By replicating data to another region, you protect against regional outages. OCI guarantees 99.95% availability for replicated data, which is critical for a financial firm's trading platform where data consistency and durability are paramount.
Disaster Recovery: With data replicated in another region, the trading platform can quickly switch to using the data in the secondary region in case of a disaster in the primary region. This setup significantly reduces recovery time objectives (RTO) and ensures business continuity.
Reference:
Oracle Cloud Infrastructure Documentation: Cross-Region Replication for Object Storage Oracle Whitepaper: High Availability and Disaster Recovery in Oracle Cloud Infrastructure Explanation of Incorrect Options:
Option A: Creating a new Object Storage bucket in another region and configuring a recycle policy to move data every 5 days does not provide real-time data availability or the fault tolerance required for a financial application. Recycle policies are intended for managing the lifecycle of data, not for high availability or disaster recovery.
Option C: While lifecycle policies are useful for moving less frequently accessed data to a more cost-effective storage tier (e.g., from Standard to Archive), they do not address cross-region redundancy or real-time availability, which are critical for this use case.
Option D: Copying an Object Storage bucket to a block volume is not a recommended practice for ensuring data durability and fault tolerance. Block volumes are used for persistent storage attached to compute instances, and copying object storage data to block volumes does not achieve the same level of redundancy and cross-region availability as replication policies.
Thus, Option B is the correct and most efficient method for ensuring high availability and fault tolerance in this scenario.
NEW QUESTION # 32
Which statement is NOT true about the Oracle Cloud Infrastructure (OCI) Object Storage service?
- A. Object Versioning is enabled at the namespace level.
- B. Object lifecycle rules can be used to archive or delete objects.
- 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 is not 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.

OCI Object Storage Overview
Object Lifecycle Management
These references provide details on how Object Storage functions and the features available.
NEW QUESTION # 33
What is the primary function of the Network Path Analyzer (NPA) tool provided by Oracle Cloud Infrastructure (OCI)?
- A. Providing real-time monitoring of network traffic to detect security threats and unauthorized access attempts
- B. Collecting and analyzing network configuration to identify virtual network configuration issues impacting connectivity
- C. Sending actual traffic between source and destination to diagnose connectivity issues
- D. Optimizing network performance by dynamically adjusting routing paths based on traffic patterns
Answer: B
Explanation:
The primary function of the Network Path Analyzer (NPA) tool in Oracle Cloud Infrastructure (OCI) is to help users troubleshoot and diagnose network connectivity issues by analyzing the network path between a source and a destination within OCI. The tool collects and analyzes the configuration of the virtual network, identifying any misconfigurations or issues that might impact connectivity.
NPA Usage: The Network Path Analyzer allows administrators to trace the network path and check for issues such as incorrect security list rules, route table misconfigurations, or any other factors that could prevent network traffic from reaching its destination.

NEW QUESTION # 34
Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OCI) File System snapshots?
- A. Snapshots are a consistent, point-in-time view of your file systems.
- B. Snapshots are accessible under the root directory of the file system at .snapshot/name.
- C. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
- D. Before you can clone a file system, at least one snapshot must exist for the file system.
Answer: C
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 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.

Oracle Cloud Infrastructure Documentation: Object Storage Tiers
NEW QUESTION # 36
Which statement accurately describes ephemeral principals?
- A. Ephemeral principals are user accounts with limited lifespans.
- B. Ephemeral principals are another term for dynamic groups.
- C. Ephemeral principals represent long-lived service accounts.
- D. Ephemeral principals are temporary credentials granted to resources.
Answer: D
Explanation:
Ephemeral principals in Oracle Cloud Infrastructure (OCI) refer to temporary security credentials granted to resources, such as compute instances, to enable them to interact with OCI services securely. These credentials have a limited lifespan and are typically used in situations where resources need to authenticate temporarily without the need for long-lived credentials.
Use Case: Ephemeral principals are often used for instance principals, allowing compute instances to make API calls without the need to manage long-term keys or credentials.
Reference:
Oracle Cloud Infrastructure Documentation: Using Instance Principals
NEW QUESTION # 37
Which statement is true about pre-authenticated requests?
- A. Deleting a pre-authenticated request does not revoke access.
- B. Pre-authenticated requests can be used to delete buckets.
- C. You need to provide your OCI credentials to the partner company.
- D. You cannot edit a pre-authenticated request.
Answer: D
Explanation:
In Oracle Cloud Infrastructure (OCI), pre-authenticated requests (PARs) allow users to grant access to specific objects in Object Storage without requiring the recipient to have an OCI account or credentials. This feature is useful for sharing objects securely without exposing broader access.
Cannot Edit a PAR: Once a pre-authenticated request is created, you cannot edit it. If you need to change the settings, such as the expiration date or the object being shared, you must delete the existing PAR and create a new one.
Other Statements:
Deleting a PAR does indeed revoke access immediately, contradicting option B.
Providing OCI credentials (C) is not required for using PARs. The purpose of PARs is to avoid sharing credentials.
Deleting Buckets (D): PARs are designed for accessing objects, not for administrative actions like deleting buckets.
Relevant OCI Documentation:
Managing Pre-Authenticated Requests
This reference outlines the features and limitations of pre-authenticated requests, including the inability to edit them once created.
NEW QUESTION # 38
How many capacity reservations would you create to meet the requirement for high availability and distribution across Availability Domains?
- A. Two
- B. One
- C. Four
- D. Three
Answer: D
Explanation:
In Oracle Cloud Infrastructure (OCI), to ensure high availability and distribution across Availability Domains (ADs), the recommended approach is as follows:
Capacity Reservations for High Availability: To achieve high availability, especially across all three Availability Domains in a region, you should create three capacity reservations. Each reservation corresponds to one AD, ensuring that your instances or resources are evenly distributed and resilient to AD-level failures.
Why Three: This setup provides redundancy and load distribution across the ADs, meeting the high availability requirements.
Relevant OCI Documentation:
Capacity Reservations
This document outlines how to create and manage capacity reservations to meet high availability and fault tolerance requirements.
NEW QUESTION # 39
What are the two types of capture filters that can be created for network monitoring?
- A. Flow log capture filters and VTAP capture filters
- B. Flow log capture filters and packet capture filters
- C. VTAP capture filters and network capture filters
- D. Flow control capture filters and traffic capture filters
Answer: A
Explanation:
In Oracle Cloud Infrastructure (OCI), there are two primary types of capture filters used for network monitoring:
Flow Log Capture Filters: These filters are used to capture and log network flow information (e.g., source and destination IP addresses, ports, protocols). Flow logs provide insights into the traffic patterns within your VCN.
VTAP Capture Filters: Virtual Test Access Point (VTAP) capture filters allow you to capture and inspect traffic from specific network interfaces or subnets without affecting the flow of traffic. This is particularly useful for deep packet inspection and monitoring purposes.

NEW QUESTION # 40
Which TWO statements are TRUE about Private IP addresses in Oracle Cloud Infrastructure (OCI)?
- A. A private IP can have an optional public IP assigned to it if it resides in a public subnet.
- B. By default, the primary VNIC of an instance in a subnet has one primary private IP address and one secondary private IP address.
- C. By default, the primary VNIC of an instance in a subnet has one primary private IP address.
- D. Each VNIC can only have one private IP address.
Answer: A,C
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 statement C.
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, A is 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 statement D.
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 # 41
Which is NOT a necessary step to complete this setup for instance principals?
- A. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
- B. Deploy the application and the SDK to all the instances that belong to the dynamic group.
- C. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
- D. Create a dynamic group with matching rules to specify which instances can make API calls against services.
Answer: C
Explanation:
Instance principals in OCI allow compute instances to directly make API calls against OCI services without requiring a user account. To set up instance principals, the following steps are necessary:
A . Deploy the application and SDK: The application running on the instances must use the OCI SDK or CLI to make API calls.
B . Create a dynamic group: Define a dynamic group with matching rules to identify which instances can use the API permissions.
C . Create a policy: Write an IAM policy that grants the dynamic group the necessary permissions to access services.
Option D is NOT necessary because instances in a dynamic group use instance principals to authenticate and do not require Auth Tokens, which are used for user authentication with APIs.

NEW QUESTION # 45
What happens to the performance level of a volume when it is detached from an instance?
- A. The performance level is adjusted to Lower Cost (0 VPUs/GB).
- B. The performance level is adjusted to Balanced.
- C. The performance level is adjusted to Higher Performance.
- D. The performance level remains unchanged.
Answer: A
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.
Reference:
Oracle Cloud Infrastructure Documentation: Block Volume Performance Levels
NEW QUESTION # 46
What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?
- A. The instance is either reboot-migrated or rebuilt in place for you.
- B. The instance will get terminated.
- C. You will receive another notification to reboot within the next 14 days.
- D. You will receive another notification to reboot within the next 7 days.
Answer: A
Explanation:
In OCI, if you choose not to proactively reboot your instance before the scheduled maintenance due date, the system will handle the maintenance automatically to ensure that the instance remains operational.
Reboot-Migration or Rebuild in Place: If you don't reboot the instance yourself, OCI will automatically perform a reboot-migration or rebuild in place for the instance. This ensures that the instance is moved to new hardware or updated without your intervention, maintaining uptime and applying necessary updates or fixes.
Impact on Instance: The exact action taken (reboot-migration or rebuild in place) depends on the type of maintenance required. However, either action will temporarily interrupt the instance, typically involving a reboot, but the instance's data and configuration will be preserved.
Relevant OCI Documentation:
Instance Maintenance
OCI Maintenance Events
These references discuss the procedures and options available for handling instance maintenance in OCI.
