質問 1：
You are trying to delete a compartment. The delete operation is falling and you need to troubleshoot the problem.
Which step should NOT be considered when troubleshooting this issue?
A. Make sure you have at least one more compartment in your tenancy other than the root compartment.
B. Verify that you have removed all resources from the compartment.
C. Verify that there are no policies In the root compartment that reference the compartment you are trying to delete.

正解：C

質問 2：
Your organization is planning on using Oracle Cloud Infrastructure (OCI) File Storage Service (FSS). You will be deploying multiple compute instance in Oracle Cloud Infrastructure (OCI) and mounting the file system to these compute instances. The file system will hold payment data processed by a Database instance and utilized by compute instances to create a overall inventory report. You need to restrict access to this data for specific compute instances and must be allowed/blocked per compute instance's CIDR block.
Which option can you use to secure access?
A. Use 'Export option' feature of FSS to restrict access to the mounted file systems.
B. Use stateless Security List rule to restrict access from known IP addresses only.
C. Create and configure OCI Web Application Firewall service with built in DNS based intelligent routing.
D. Create a new VCN security list, choose SOURCE TYPE as Service and SOURCE SERVICE as FSS. Add stateless ingress and egress rules for specific P address and CIDR blocks.

質問 3：
An upcoming e-commerce company has deployed their online shopping application on OCI. The application was deployed on compute instances with autoscaling configuration for application servers fronted by a load balancer and OCI Autonomous Transaction Processing (ATP) in the backend.
In order to promote their e-commerce platform 50% discount was announced on all the products for a limited period. During the day 1 of promotional period it was observed that the application is running slow and company's hotline is flooded with complaints.
What could be two possible reasons for this situation?
A. The health check on some of the backend servers has failed and the load balancer was rebooting these servers.
B. As part of autoscaling, the load balancer shape has dynamically changed to a larger shape to handle more incoming traffic and the system was slow for a short time during this change
C. The autoscaling has already scaled to the maximum number of instances specified in the configuration and there is no room of scaling
D. The health check on some of the backend servers has failed and the load balancer has taken those servers temporarily out of rotation
正解：C,D

質問 4：
Your company will soon start moving critical systems Into Oracle Cloud Infrastructure (OCI) platform. These systems will reside in the us-phoenix-1and us-ashburn 1 regions. As part of the migration planning, you are reviewing the company's existing security policies and written guidelines for the OCI platform usage within the company. you have to work with the company managed key.
Which two options ensure compliance with this policy?
A. When you create a new OCI Object Storage bucket through OCI console, you need to choose "ENCRYPT USING CUSTOMER-MANAGED KEYS" option.
B. When you create a new compute instance through OCI console, you use the default options for "configure boot volume" to speed up the process to create this compute instance.
C. You do not need to perform any additional actions because the OCI Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption.
D. When you create a new compute instance through OCI console, you use the default shape to speed up the process to create this compute instance.
E. When you create a new block volume through OCI console, select Encrypt using Key Management checkbox and use encryption keys generated and stored in OCI Key Management Service.
正解：A,E

質問 6：
You are responsible for migrating your on premises legacy databases on 11.2.0.4 version to Autonomous Transaction Processing Dedicated (ATP-D) In Oracle Cloud Infrastructure (OCI). As a solution architect, you need to plan your migration approach.
Which two options do you need to implement together to migrate your on premises databases to OCI?
A. Retain changes to Oracle shipped privileges, stored procedures or views In the on-premises databases.
B. Convert on-premises databases to PDB, upgrade to 19c, and encrypt Migration.
C. Retain all legacy structures and unsupported features (e.g. taw U>Bs) In the onuses databases for migration.
D. Use Oracle Data Guard to keep on premises database always active during migration
E. Use Oracle GoldenGate replication to keep on premises database online during migration.
正解：B,E

質問 7：
You have been asked to implement a bespoke financial application in Oracle Cloud Infrastructure using virtual machine instances controlled by Autoscaling across multiple Availability Domains. The application stores transaction logs, intermediate transaction data, and audit data and needs to store this on a persistent, durable data store accessible from all of the application servers. The application requires the file system to be mounted in the /audit folder on the Linux file system. The system needs to tolerate the failure of two or more Fault Domains and still maintain data integrity. The solution should be as low maintenance as possible.
What storage architecture should you suggest?
A. Use locally attached NVMe instances and configure RAID 0 replication between servers.
B. Use File Storage Service(FSS). Configure FSS to operate from all Availability Domains the application servers operate in and mount the file system in the /audit folder.
C. Store the data on Oracle Object Storage mounted at the /audit mount point on all the Linux instances using the default mount options.
D. Implement a single instance and install an NFS server, configure and create an NFS share, and mount this as /audit on the application instances.
正解：B

質問 8：
Your company developed a function that needs to access the Oracle Database to inject some data to it at runtime. You are tasked to move this function to the Oracle Cloud Infrastructure (OCI) and use Oracle Functions and access Oracle Autonomous Database. You created a Dockerfile below to run this function, however, you are getting this error "cx_Oracle.DatabaseError: ORA""12560: TNS:protocol adapter error".

What should you do to make sure that Oracle Functions can run this Dockerfile properly? (Choose the best answer.)
A. Use """"privileged flag while running the Docker container to add runtime privilege
B. Add these two lines to your Dockerfile: groupadd """"gid 1000 fn && \ adduser """"uid 1000 """"gid fn fn
C. You ned to run this Container as root, so add this line: USER root
D. Use """"cap""add=ALL flag while running the Docker container to add runtime capability
