NEW QUESTION # 149
Which of the following TWO statements are TRUE about deleting a Kubernetes cluster? (Choose two.)
Answer: D,E
Explanation:
The correct statements about deleting a Kubernetes cluster are: If you change the auto-generated name of a worker node and then delete the cluster, the renamed worker node is not deleted. Changing the name of a worker node does not affect its deletion when the cluster is deleted. The cluster deletion process does not consider the renamed worker nodes and will delete all worker nodes associated with the cluster. Upon deleting a cluster, no other resources created during the cluster creation process or associated with the cluster (such as VCNs, Internet Gateways, NAT Gateways, Route Tables, Security Lists, Load Balancers, and Block Volumes) are deleted automatically. These additional resources are not automatically deleted when the cluster is deleted. You need to manage the deletion of these resources separately, if desired. Therefore, the correct statements are that the renamed worker nodes are not deleted when the cluster is deleted, and other associated resources are not automatically deleted when the cluster is deleted.
NEW QUESTION # 150
As a Cloud Native developer, you have written a web service for your company. However, your security team has suggested that your web service should address Distributed Denial-of-Service (DDoS) attack. You are time-constrained and you need to ensure that this is implemented as soon as possible. What should you do in this scenario? (Choose the best answer.)
Answer: C
Explanation:
The correct answer in this scenario is to use the OCI API Gateway service and configure rate limiting. Using the OCI API Gateway service and configuring rate limiting is an effective approach to address Distributed Denial-of-Service (DDoS) attacks. By implementing rate limiting, you can control the number of requests that can be made to your web service within a specific time frame. This helps to prevent overload and ensures that your service can handle legitimate traffic while mitigating the impact of DDoS attacks. By leveraging the OCI API Gateway service, you can easily configure rate limiting rules to restrict the number of requests per second or per minute. This allows you to set appropriate thresholds and safeguard your web service from being overwhelmed by excessive requests. The API Gateway acts as a protective layer, filtering out malicious traffic and ensuring the smooth operation of your service. While options like OCI Virtual Cloud Network (VCN) segregation and third-party service integrations may contribute to overall security, they do not specifically address DDoS attacks as efficiently as rate limiting. VCN segregation focuses more on network segmentation and isolation, while third-party service integration may introduce additional dependencies and complexities.
Re-writing your web service and implementing rate limiting is a viable option, but it may not be feasible considering the time constraints mentioned. Leveraging the OCI API Gateway service provides a quicker and easier solution to implement DDoS attack mitigation through rate limiting.
NEW QUESTION # 151
Which statement is NOT valid regarding the filter matching behavior of Oracle Cloud Infrastructure (OCI) Events rules?
Answer: C
Explanation:
Oracle ' s Events documentation explicitly states that wildcard matching with * is supported only inattribute values, not in attribute keys. The asterisk can appear at the beginning, middle, or end of a value, but field names themselves must remain literal. Oracle also confirms all three other behaviors. An empty {} condition matches every applicable event; Events rules apply to their compartment and child compartments; and an event must contain every field named in the condition using the same nesting structure. Therefore, option C improperly extends wildcard functionality to attribute keys. The valid model is to preserve the exact JSON field structure while applying wildcard patterns only to values associated with those fields.
NEW QUESTION # 152
Which special column in the OCI Logging Query Language represents the raw text of the entire original log message?
Answer: D
Explanation:
Oracle ' s Logging Query Language specification defines logContent as aspecial column representing the text of the whole original message. This field is particularly valuable when the required information is not available through a known indexed JSON field or when administrators need full-text matching across the original log payload. For example, Oracle documents queries such as where logContent = ' *ERROR* ' to return log lines containing the specified text. messageBody, rawPayload, and eventSource are not documented LQL special columns representing the complete original message. Individual services can contain fields such as data.message, but those fields are part of the service-specific structured payload rather than the universal raw-message special column. Therefore, A is correct.
NEW QUESTION # 153
Which of the following is defined as a configurable, low-latency infrastructure layer that controls the interaction between a network of microservices? (Choose the best answer.)
Answer: A
Explanation:
The correct answer is " Service Mesh. " A service mesh is a configurable, low-latency infrastructure layer that controls the interaction between a network of microservices. It provides functionalities such as service discovery, load balancing, traffic management, security, and observability for microservices-based applications. It is designed to improve communication and manage the complex interactions between services within a distributed system. Service mesh frameworks like Istio and Linkerd are commonly used to implement service mesh architecture.
