How do you replay all the existing messages in a Kafka topic by using the Flink job?
- A. Restart the Flink job.
- B. Stop the Mink job. Reset the consumer group offset value to oldest and start the job.
- C. Increase the number of partitions of the Kalka topic and restart the Flink job.
- D. Change the retention period to zero and revert to the previous value for the Kalka topic.
正解：B
解説：
To replay all messages in a Kafka topic using a Flink job, you would typically stop the job, reset the consumer group offset to the earliest position (often referred to as 'oldest'), and then restart the job. This process ensures that the Flink job will reprocess all messages from the beginning of the topic.

Which Cypher query should you use to retrieve the count of nodes with a specific label in a Neo4j HA cluster'.'
- A. COUNT (n:Label)
- B. MATCH (n:Label> RETURN COUNT*n)
- C. MATCH (n) WHERE n.label="Label" RFTURN COUNT(n)
- D. RETURN COUNT(n:Label)
正解：B

Which two API microservices are exposed by Sunbird Lern?
- A. Certificate-Service
- B. Batch-Service
- C. Learning-Service
- D. Knowledge-Service
- E. User-Org-Service
正解：C、E
解説：
In the context of microservices architecture, services like User-Org-Service and Learning-Service are commonly exposed to handle specific functionalities such as user and organization management, and learning management respectively. Batch-Service, Knowledge-Service, and Certificate-Service might be part of the ecosystem but the naming convention suggests that User-Org-Service and Learning-Service are more likely to be the core services exposed by an educational platform like Sunbird Lern.

- D. 0.0.0.0/0
正解：B
解説：
'oci-local-vcn' is not a valid source CIDR for a security list rule in Oracle Cloud Infrastructure VCNs. Security list rules are configured using CIDR notation to specify allowed or denied IP address ranges for ingress and egress traffic. Valid CIDR notations include specific IP ranges like '0.0.0.0/0', '10.0.1.0/24', and
'192.168.1.0/24'.

解説：
Drift Detection is a feature in OCI Resource Manager that helps users identify discrepancies between the real-world state of their infrastructure and the configuration defined in their Terraform state file. This feature is crucial for maintaining the integrity of infrastructure deployments, as it highlights unintended changes or drifts that might have occurred outside of Terraform's management.
質問 # 32
Which Oracle Cloud Infrastructure (OCI) IAM policy statement should be defined to ensure that members of the NetworkAdmins group can create and configure Virtual Cloud Network components in the Project-A compartment?
