최신 Oracle Cloud Infrastructure 1z0-1084-26 무료샘플문제 (Q157-Q162):

질문 # 157
Which component of the Docker architecture is the persistent background service responsible for managing container lifecycles, local images, networks, and storage volumes?

A. Docker Compose
B. Docker Daemon
C. Docker Registry
D. Docker Client

정답：B

설명：
The Docker daemon, implemented as the dockerd background process, runs continuously on a Docker host and performs the server-side container-management operations requested through the Docker API. It manages container execution, images, storage drivers and volumes, and networking. The Docker client is the command interface that sends requests to that daemon; it does not itself manage container lifecycles. A Docker registry such as OCIR stores and distributes images remotely, while Docker Compose describes and coordinates multi- container application configurations. Oracle ' s Linux container documentation explicitly refers to the Docker Engine daemon and its dockerd process, and Oracle Functions troubleshooting likewise distinguishes the local Docker client/daemon from the remote registry. Therefore, the persistent management component described in the question is the Docker Daemon.

질문 # 158
You are tasked with configuring access for a new developer group named ops-team in OCI. Members of this group must be able to publish raw data points to a custom metric namespace named AppPerformance in the tenancy, and they must also be able to run queries to view both service and custom metrics in a target compartment named production-cmp.
Which TWO IAM policy statements must be written to satisfy these requirements?

A. Allow group ops-team to inspect metrics in compartment production-cmp to list application metrics
B. Allow group ops-team to manage metrics in compartment production-cmp to query application metrics
C. Allow group ops-team to read metrics in compartment production-cmp to query application metrics
D. Allow group ops-team to use metrics in tenancy where target.metrics.namespace= ' AppPerformance '
E. Allow group ops-team to publish metrics in tenancy where target.metrics.namespace= ' AppPerformance '

정답：C,D

설명：
OCI Monitoring IAM maps the use metrics verb to metric write capability, including METRIC_WRITE and the PostMetricData operation. Oracle specifically documents the pattern Allow group < group > to use metrics in tenancy where target.metrics.namespace= ' < namespace > ' for publishing custom metric data.
Therefore, E grants publishing access specifically to AppPerformance. Querying metric data requires read metrics, which includes METRIC_READ and SummarizeMetricsData; B consequently gives the group the required query access in production-cmp. publish is not an OCI IAM policy verb, inspect permits listing metric metadata but not retrieving data points, and manage provides unnecessary privilege. B and E therefore implement the stated requirements using the appropriate least-privilege Monitoring verbs.

질문 # 159
Which of these is NOT a valid authentication method for accessing an OCI API Gateway deployment?

A. OAuth
B. SAML Token
C. API Key
D. HTTP Basic

정답：B

설명：
OCI API Gateway supports the following authentication methods for accessing an API deployment3:
* HTTP Basic: The client sends a username and password with each request. The credentials are validated against a user database in Oracle Identity Cloud Service (IDCS).
* API Key: The client sends an API key with each request. The API key is validated against a list of keys stored in IDCS or OCI Vault.
* OAuth: The client obtains an access token from an authorization server (such as IDCS) and sends it with each request. The access token is validated against the authorization server and optionally checked for required scopes.
* JWT Token: The client obtains a JSON Web Token (JWT) from an identity provider (such as IDCS or OCI IAM) and sends it with each request. The JWT is validated against the identity provider's public key and optionally checked for required claims. SAML Token is not a valid authentication method for accessing an OCI API Gateway deployment. SAML is an XML-based standard for exchanging authentication and authorization data between different parties, such as a service provider and an identity provider4. SAML tokens are typically used for web browser single sign-on (SSO) scenarios, not for API access4.

질문 # 160
You are developing a real-time monitoring application for a fleet of vehicles, which will be deployed on Oracle Cloud Infrastructure (OCI). You need to choose between using OCI Queue or OCI Streaming to handle the real-time data feeds from the vehicles. Based on the scenario described, which is the most appropriate choice for handling real-time data feeds?

A. OCI Streaming, because it offers exactly-once message delivery, which is necessary for real-time applications
B. OCI Queue, because it provides at-least-once message delivery, which is critical for real-time monitoring applications
C. OCI Streaming, because it is designed for high-volume, continuous ingestion and processing of data, making it the best choice for a fleet of vehicles
D. OCI Queue, because it is optimized for low-latency messaging and ideal for real-time applications

정답：C

설명：
OCI Streaming is a fully managed, scalable, and durable messaging solution for ingesting continuous, high- volume streams of data that you can consume and process in real-time1. Streaming is suitable for any use case in which data is produced and processed continually and sequentially in a publish-subscribe messaging model1. Streaming can handle millions of messages per second with low latency2. Therefore, OCI Streaming is the most appropriate choice for handling real-time data feeds from a fleet of vehicles.Verified References: Overview of Streaming, Container Engine for Kubernetes

질문 # 161
Which statement is NOT valid regarding the design best practices for microservices?

A. Idempotency ensures that calling a microservice multiple times with the same parameters produces the exact same outcome.
B. Flexible communication requires all microservices to use the same synchronous protocol for both external and internal communication.
C. Backward compatibility dictates that API updates and parameter changes must not break existing clients consuming the microservice.
D. Responsive microservices must return a standard response to requesting clients even when the underlying service execution fails.

정답：B

설명：
Oracle ' s microservices design guidance explicitly identifies responsive behavior, backward compatibility, flexible communication, and idempotency as important requirements. Flexible communication doesnotrequire every microservice to use one synchronous protocol. Oracle states that each microservice can specify the protocol used between clients and the API gateway as well as the protocol used between individual microservices. This flexibility supports loose coupling and allows synchronous or asynchronous communication where appropriate. Oracle also states that microservices should return a response even when the service fails, API changes should remain backward-compatible with existing clients, and repeated calls should produce the same outcome when idempotency is required. Consequently, option C directly contradicts Oracle ' s documented flexible-communication principle and is the NOT valid statement.
