問題 #39
Which statement is NOT valid regarding context variables used for dynamic backend routing in Oracle Cloud Infrastructure API Gateway?

A. The context variable request.auth[ < key > ] can be used to dynamically select a backend based on claims returned by an authorizer function or contained in a JWT.
B. The context variable request.query[ < key > ] can be used to dynamically select a backend based on the value of a specific query parameter in the incoming request.
C. The context variable request.headers[ < key > ] can be used to dynamically select a backend based on the value of a specific HTTP header in the incoming request.
D. The context variable request.body[ < key > ] can be used to dynamically select a backend based on parsing specific key-value fields from an incoming JSON payload.

答案：D

解題說明：
Oracle API Gateway documents the context-variable selectors available for dynamic backend routing.
Supported selectors include request.auth[ < key > ], request.headers[ < key > ], request.host, request.path[ < key > ], request.query[ < key > ], request.subdomain[ < key > ], and usage-plan information. Therefore, headers, authentication claims, and query parameters can all participate directly in backend-selection rules.
Although API Gateway can expose the request body to amulti-argument authorizer function, Oracle does not list request.body[ < key > ] as a supported selector for dynamic backend routing. Its presence in that separate authorizer context does not make it a dynamic-routing selector capable of parsing arbitrary JSON fields.
Consequently, A, B, and C describe supported routing context variables, while D incorrectly extends the routing model to request-body key selection.

問題 #40
Which resolution rule does an Oracle Cloud Infrastructure API Gateway apply when determining the routing target for an incoming request that matches multiple overlapping route paths within a deployment?

A. Longest path match
B. First defined route
C. Shortest path match
D. Alphabetical route order

答案：A

解題說明：
The Word source identifiesLongest path matchas the answer, meaning the more specific matching route takes precedence when a request could satisfy multiple path patterns. This is consistent with the general routing principle that more specific path patterns take precedence over broader prefixes. Oracle ' s current OCI API Gateway documentation confirms that deployment routes are defined using URL path patterns and that path parameters and wildcard segments can be used for matching requests to backends. However, the currently published OCI API Gateway pages retrieved for verification do not explicitly state a universal "longest path match" precedence rule for overlapping deployment routes. Therefore, C is the answer recorded in the supplied source, but this particular rule is not stated verbatim in the current OCI API Gateway documentation located during verification.

問題 #41
Your organization mandates that all containerized workloads deployed to Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes (OKE) must utilize Kubernetes NetworkPolicy resources, such as Calico, to enforce strict micro-segmentation of traffic. You have deployed these workloads to an enhanced OKE cluster using virtual node pools to minimize infrastructure maintenance. During testing, you discover that the Calico installation fails because NetworkPolicy resources and third-party CNI policy integrations are completely unsupported on this specific node configuration. How should you resolve this security implementation challenge while continuing to use VCN-Native Pod Networking?

A. Migrate your workloads to managed node pools within the OKE cluster, where VCN-Native Pod Networking supports Calico for NetworkPolicy enforcement.
B. Define an OCI IAM policy that grants the OKE workload identity access to manage network security lists at the virtual node level.
C. Reconfigure your virtual node pools to use the Flannel overlay plugin, which natively implements network policy isolation on virtual nodes.
D. Upgrade your OKE virtual nodes to Kubernetes version 1.30 or higher, which enables native, agentless NetworkPolicy support on virtual nodes.

答案：A

解題說明：
Oracle explicitly states that virtual nodes do not support Kubernetes NetworkPolicy resources or network providers such as Calico and Cilium that provide NetworkPolicy enforcement. Virtual nodes support only OCI VCN-Native Pod Networking and cannot use Flannel or other third-party CNI plugins. By contrast, Calico can be installed with managed node pools while retaining VCN-native pod networking. This combination enables Kubernetes NetworkPolicy objects to enforce pod-level traffic controls and micro- segmentation. An IAM policy or network security list cannot substitute for Kubernetes NetworkPolicy because OCI network controls and Kubernetes pod policy enforcement operate at different layers. Therefore, when Calico-based NetworkPolicy enforcement is mandatory, migrating the workload from virtual nodes to managed node pools is the supported OKE architecture.

問題 #42
Which statement is NOT valid regarding the structure and behavior of Docker images and containers?

A. A Docker image is composed of a series of read-only layers that represent filesystem differences.
B. Modifying an existing file within a running container copies the file from the read-only layer to the writable layer.
C. Running a Docker container adds a thin writable layer on top of the underlying read-only image layers.
D. Deleting a Docker container also permanently deletes the underlying image from the host system by default.

答案：D

解題說明：
Docker images and containers have separate lifecycles. Oracle describes a Docker image as a read-only template used to create containers, while image implementations consist of immutable read-only layers. A running container adds its own writable runtime state without changing those underlying image layers.
Removing a container with docker rm removes that container instance; deleting the corresponding image requires a separate image-removal operation such as docker rmi. Oracle ' s Cloud Shell documentation likewise explicitly uses docker rmi when deleting local images. Therefore, deleting a container doesnotautomatically or permanently delete its source image. Statements A, B, and D describe the layered and copy-on-write behavior associated with Docker containers, making C the invalid statement.

問題 #43
You are developing a polyglot serverless application using Oracle Functions. Which language cannot be used to write your function code?

A. PL/SQL
B. Go
C. Python
D. Java
E. Node.js

答案：A

解題說明：
Oracle Functions does not currently support PL/SQL as a language for writing function code. PL/SQL is a procedural language used in Oracle Database for developing stored procedures, triggers, and other database- related code. However, Oracle Functions supports several other popular programming languages such as Go, Node.js, Python, and Java, allowing developers to choose the language that best suits their application requirements and their familiarity with the language. While PL/SQL is powerful for working with the Oracle Database, it is not an option for writing function code in the Oracle Functions serverless architecture.
