質問 1：
Recently, your e-commerce web application has been receiving significantly more traffic than usual. Users are reporting they often encounter a 503 Service Error when trying to access your site. Sometimes the site is very slow.
You check your instance pool configuration to confirm that the maximum number of instances is configured to allow 20 compute instances. Currently, 14 compute instances have been provisioned by the instance pool.
You also confirm that current CPU utilization across all hosts exceeds the scale-out threshold you set in your auto-scaling policy. However, the instance pool is not provisioning any new instances.
What can you check to determine why the application is NOT functioning properly? (Choose the best answer.)
A. Verify that the new offer feature code did not introduce any performance bugs.
B. Verify that the database is accessible.
C. Verify that the Quality Assurance team is not currently performing load-testing against production.
D. Verify that the compute resource quota has not been exceeded.
正解：D

質問 2：
Your deployment platform within Oracle Cloud Infrastructure (OCI) leverages a compute instance with multiple block volumes attached. There are multiple teams that use the same compute instance and have access to these block volumes. You want to ensure that no one accidentally deletes any of these block volumes. You have started to construct the following IAM policy but need to determine which permissions should be used.
allow group DeploymentUsers to manage volume-family where ANY
{ request.permission != <???>, request.permission != <???>, request.permission !=
<???> }
Which permissions can you use in place of <???> in this policy? (Choose the best answer.)
A. DELETE_VOLUME, DELETE_VOLUME_ATTACHMENT, DELETE_VOLUME_BACKUP
B. VOLUME_ERASE, VOLUME_ATTACHMENT_ERASE, VOLUME_BACKUP_ERASE
C. ERASE_VOLUME, ERASE_VOLUME_ATTACHMENT, ERASE_VOLUME_BACKUP
D. VOLUME_DELETE, VOLUME_ATTACHMENT_DELETE, VOLUME_BACKUP_DELETE

質問 3：
You have been asked to set up connectivity between a client's on-premises network and Oracle Cloud Infrastructure (OCI). The requirements are:
Low latency: The applications are financial and require low latency connectivity into OCI. Consistency: The application isn't tolerant of performance variation.
Performance: The communications link needs to support up to 1.25 Gbps.
Encryption: The communications link needs to encrypt any data in transit between the on-premises network and OCI Virtual Cloud Network (VCN).
The client wants to implement the above with as low a cost as possible, while meeting all of the requirements. What should you suggest? (Choose the best answer.)
A. Provision a site-to-site IPsec VPN between your on-premises network and your virtual cloud network (VCN) using VPN Connect.
B. Provision FastConnect with a single public virtual circuit.
C. Provision FastConnect with a single public virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.
D. Provision FastConnect with a single private virtual circuit.
E. Provision FastConnect with a single private virtual circuit, and run an IPsec VPN tunnel over the top of this virtual circuit.
