質問 # 104
What is the difference between blue/green and canary deployment strategies? (Choose the best answer.)

A. In blue/green, current applications are slowly replaced with new ones. In canary, the application Is deployed Incrementally to a select group of people.
B. In blue/green, current applications are slowly replaced with new ones. In canary, both old and new applications are in production at the same time.
C. In blue/green, both old and new applications are in production at the same time. In canary, the application Is deployed incrementally to a select group of people.
D. In blue/green, the application Is deployed In minor Increments to a select group of people. In canary, both old and new applications are simultaneously in production.

正解：C

解説：
The correct answer is: In blue/green deployment, both old and new applications are in production at the same time. In canary deployment, the application is deployed incrementally to a select group of people. In a blue
/green deployment strategy, two identical environments, referred to as blue and green, are set up. The current production environment (blue) continues to serve live traffic while a new version of the application is deployed in the green environment. Once the new version is tested and deemed stable, traffic is routed from the blue environment to the green environment, making it the new production environment. This approach allows for a seamless switch between the old and new versions of the application. On the other hand, in a canary deployment strategy, the new version of the application is deployed incrementally to a small subset of users or a specific group. This allows for testing the new version in a real production environment while minimizing the impact of any potential issues. If the new version performs well and meets the desired criteria, it can be gradually rolled out to a larger audience or the entire user base. In summary, the main difference between blue/green and canary deployment strategies lies in how the deployment is managed. Blue/green involves simultaneous production of both old and new applications, while canary deployment focuses on incremental deployment to a select group of users.

質問 # 105
What is the maximum execution time of Oracle Functions?

A. 120 seconds
B. 240 seconds
C. 60 seconds
D. 300 seconds

正解：D

解説：
The maximum execution time of Oracle Functions is 300 seconds, which is equivalent to 5 minutes. This means that a function running within Oracle Functions cannot exceed a runtime of 5 minutes. If a function requires longer execution times, alternative approaches such as invoking external services asynchronously or using long-running processes should be considered. It is important to design functions with this execution time limitation in mind to ensure optimal performance and efficiency within the Oracle Functions platform.

質問 # 106
How are cloud native application versions deployed to an OKE cluster when using a blue/green deployment strategy?

A. Current applications are slowly replaced with new application versions.
B. Both old and new application versions are deployed to production at the same time.
C. New application versions are deployed in minor increments to a select group of people.

正解：B

解説：
Blue/Green deployment strategy allows releasing a new version of an application using two identical environments where one of them is active at a given time. The current version of the application is provisioned on the active environment, whereas the new version gets deployed to the standby environment1. The traffic is shifted from the active to the standby environment by updating the ingress resource2. Therefore, both old and new application versions are deployed to production at the same time, but only one of them receives the traffic.

質問 # 107
You are developing a serverless application with Oracle Functions and Oracle Cloud Infrastructure Object Storage. Your function needs to read a JSON file object from an Object Storage bucket named " input-bucket
" in compartment " qa-compartment " . Your corporate security standards mandate the use of Resource Principals for this use case. Which two statements are needed to implement this use case? (Choose two.)

A. Set up a policy with the following statement to grant read access to the bucket: allow dynamic-group read-file-dg to read objects in compartment qa- compartment where target.bucket.name= ' input-bucket '
B. Set up a policy to grant all functions read access to the bucket: allow all functions in compartment qa- compartment to read objects in target.bucket.name= " input-bucket '
C. Set up a policy to grant your user account read access to the bucket: allow user XYZ to read objects in compartment qa-compartment where target.bucket.name= " input-bucket '
D. No policies are needed. By default, every function has read access to Object Storage buckets in the tenancy.
E. Set up the following dynamic group for your function ' s OCID: Name: read-file-dg Rule: resource.id =
" ocid1.fnfunc.oc1.phx.aaaaaaaakeaobctakezjz5i4ujj7g25q7sx5m vr55pms6f4da '

正解：A、E

解説：
The correct answers are: Set up the following dynamic group for your function ' s OCID: Name: read-file-dg Rule: resource.id = " ocid1.fnfunc.oc1.phx.aaaaaaaakeaobctakezjz5i4ujj7g25q7sx5mvr55pms6f4da " Set up a policy with the following statement to grant read access to the bucket: Statement: allow dynamic-group read- file-dg to read objects in compartment qa-compartment where target.bucket.name = ' input-bucket ' Explanation: To implement the use case of reading a JSON file object from an Object Storage bucket using Resource Principals with Oracle Functions, you need to configure the following: Create a dynamic group named " read-file-dg " and associate it with your function ' s OCID. This dynamic group helps identify the function as a member of the group for policy enforcement. Create a policy that grants read access to the bucket. The policy statement should allow the dynamic group " read-file-dg " to read objects in the compartment " qa-compartment " and specify the target bucket name as " input-bucket " . This policy ensures that the function has the necessary permissions to access the specified bucket. By setting up the dynamic group and policy, you ensure that the function, as a member of the dynamic group, has the required read access to the specified Object Storage bucket in the specified compartment.

質問 # 108
You are deploying a serverless data integration pipeline where an OCI Function needs to consume real-time events from an OCI Stream in the prod-compartment compartment. Your corporate security policy mandates strict least-privilege access, meaning the function must only be permitted to consume (pull) messages, with absolutely no capability to publish (push) messages to the stream. Which TWO configurations are required to establish this granular authorization using a Dynamic Group named analytics-function-dg?

A. Create an IAM policy statement: Allow dynamic-group analytics-function-dg to use streams in compartment prod-compartment
B. Create a dynamic group rule to match the function: ALL {resource.type = ' fnfunc ' , resource.
compartment.id = ' ocid1.compartment.oc1..example ' }
C. Create an IAM policy statement: Allow dynamic-group analytics-function-dg to use stream-push in compartment prod-compartment
D. Create a dynamic group rule to match the function: ALL {resource.type = ' compute ' , resource.
compartment.id = ' ocid1.compartment.oc1..example ' }
E. Create an IAM policy statement: Allow dynamic-group analytics-function-dg to use stream-pull in compartment prod-compartment

正解：B、E

解説：
Oracle Streaming exposes separate IAM resource types for producers and consumers. Granting use stream- pull provides STREAM_CONSUME, covering operations such as GetMessages, CreateCursor, group cursors, heartbeats, and commits without granting STREAM_PRODUCE. Granting use streams would be broader because that resource type includes both production and consumption capabilities. Oracle Functions can be placed in a dynamic group with a rule using resource.type = ' fnfunc ' together with the Function ' s compartment OCID. compute would not match an Oracle Function resource, and stream-push provides the opposite permission by allowing message publication. Therefore, A establishes consume-only Streaming permission while C correctly associates the Functions resources with the dynamic group.
