問題 #21
Which image option allows you to create identical instances with minimal effort?
- A. Bring your own image
- B. Create a custom image
- C. Use Oracle-provided images
- D. Select an image from the OCI Marketplace
答案：B
解題說明：
When you need to create identical instances with minimal effort, creating a custom image is the best option.
Custom Images: A custom image captures the exact configuration of an instance, including the OS, software, configurations, and data. By using a custom image, you can easily replicate the same setup across multiple instances, ensuring consistency and reducing the need for manual configuration each time.
Other Options:
Bring Your Own Image: This allows you to import your custom OS image into OCI, but it's more suited for cases where you are migrating from another environment.
Select an Image from the OCI Marketplace: This provides pre-configured images from Oracle or third parties, but they may require additional setup to match your specific requirements.
Use Oracle-Provided Images: These are basic images provided by Oracle, which may not include the specific customizations you need.
Relevant OCI Documentation:
Custom Images Overview
This resource explains how to create and use custom images for quickly deploying identical instances.
問題 #22
You want to protect your VM instance from low-level threats, such as rootkits and bootkits. What should you do?
- A. Create a shielded instance.
- B. Use in-transit encryption.
- C. Use Vulnerability Scanning Service.
- D. Create a burstable instance.
答案：A
解題說明：
To protect your VM instance from low-level threats, such as rootkits and bootkits, you should create a shielded instance in Oracle Cloud Infrastructure (OCI). Shielded instances are designed to provide enhanced security features, including:
Secure Boot: Ensures that the instance boots only with trusted software.
Measured Boot: Records boot metrics, allowing verification that the instance has not been tampered with.
Trusted Platform Module (TPM): Provides additional security through cryptographic functions.
These features help protect against low-level threats that could compromise the integrity of the instance at boot time.

Oracle Cloud Infrastructure Documentation: Shielded Instances
問題 #23
How can an organization securely grant a third-party application access to specific OCI resources?
- A. By creating an IAM policy granting full access to the tenancy
- B. By sharing user credentials for an OCI administrator
- C. By implementing OAuth 2.0 with the application
- D. By configuring the application to utilize Instance Principal
答案：D
解題說明：
To securely grant a third-party application access to specific Oracle Cloud Infrastructure (OCI) resources, the recommended approach is to configure the application to use Instance Principal. This method allows the application to authenticate directly with OCI services without needing to manage sensitive credentials like passwords or API keys.
Instance Principals: Enable compute instances to directly make API calls against OCI services, inheriting permissions through IAM policies. This setup is more secure than sharing user credentials, as it avoids hardcoding credentials within the application and leverages OCI's native security features.
Reference:
Oracle Cloud Infrastructure Documentation: Instance Principals
問題 #24
Which statement is true about instance configurations and instance pools in OCI?
- A. You can only delete an instance configuration if it is not associated with any instance pool.
- B. You can delete an instance configuration if it is associated with an instance pool.
- C. You cannot reuse the same instance configuration for multiple instance pools.
- D. An instance pool can have multiple instance configurations associated with it.
答案：A
問題 #25
Which compute capacity type would you select to meet these requirements?
- A. Dedicated host
- B. On-demand capacity
- C. Preemptible capacity
- D. Capacity reservation
答案：B
解題說明：
On-demand capacity is the compute capacity type in Oracle Cloud Infrastructure (OCI) that allows you to provision and use compute instances whenever needed, without any long-term commitment. This flexibility is ideal for various workloads, including development, testing, and production environments, where immediate availability and scalability are crucial.
Key Points:
On-Demand Capacity: On-demand compute instances provide users with the flexibility to spin up instances as required and only pay for the time the instances are running. This model is most suitable for workloads with unpredictable usage patterns or short-term requirements.
Flexibility and Scalability: With on-demand capacity, you can quickly scale your resources up or down based on your application's needs, ensuring that you only pay for the resources you actually use.
No Commitment: Unlike reserved capacity, on-demand capacity does not require any long-term commitment or upfront payment, making it an attractive option for organizations looking to avoid capital expenditures.
Reference:
Oracle Cloud Infrastructure Documentation: OCI Compute Pricing
Oracle Cloud Infrastructure Documentation: Compute Instance Lifecycle
Explanation of Incorrect Options:
A . Capacity reservation: This option allows you to reserve capacity in advance, ensuring that resources are available when needed. It's ideal for predictable workloads but may not be as cost-effective for fluctuating demands.
B . Preemptible capacity: Preemptible instances are a lower-cost option where instances can be terminated by OCI if resources are needed elsewhere. This is suitable for non-critical workloads that can tolerate interruptions.
D . Dedicated host: Dedicated hosts provide physical servers for your exclusive use, offering isolation and predictable performance. This option is more suitable for workloads requiring dedicated resources or compliance needs.
Thus, Option C: On-demand capacity is the correct choice for most general-purpose workloads needing flexibility and immediate availability without long-term commitment.
