- A. Restricting resource creation based on predefined security policies
- B. Continuous monitoring of security posture
- C. Automatically enforcing security best practices
- D. Storing and managing encryption keys and secrets
正解：D
解説：
Storing and managing encryption keys and secrets is not a feature provided by Oracle Cloud Infrastructure Security Zones. This functionality is typically handled by other services such as Oracle Key Management Service (KMS) or Vault.
質問 # 26
What is an availability domain in Oracle Cloud Infrastructure?
- A. One or more data centers located within a region
- B. A set of virtual cloud networks
- C. A type of encrypted traffic
- D. A localized geographical area
正解：A
解説：
An availability domain in Oracle Cloud Infrastructure refers to one or more data centers located within a region. Each availability domain is isolated from the others, with its own power, cooling, and networking to ensure fault tolerance and reliability.
質問 # 27
Which is NOT a component of an Identity and Access Management (IAM) policy statement in Oracle Cloud Infrastructure?
- A. Data backup frequency
- B. Action Verb
- C. Location
- D. Resource-type
正解：A
解説：
IAM policies define access control by specifying who can access which resources and what actions they can perform. Data backup frequency is not a component of IAM policy statements.
質問 # 28
In Oracle Cloud Infrastructure Object Storage Service, which storage tier is designed for rarely accessed data that can be restored within hours?
- A. Standard Storage
- B. Intelligent Tiering
- C. Archive Storage
- D. One Zone-Infrequent Access
正解：C
解説：
Archive Storage in Oracle Cloud Infrastructure Object Storage Service is designed for rarely accessed data that can be restored within hours. It is the most cost-effective storage tier for long-term data retention and archiving purposes.
質問 # 29
What is the primary function of a Route Table in the Oracle Cloud Infrastructure Networking service?
- A. To provide a private connection between a VCN and an on-premises network
- B. To define rules controlling traffic flow between subnets
- C. To connect a VCN to the public Internet
- D. To define rules to route traffic from subnets to destinations outside the VCN
正解：D
解説：
The primary function of a Route Table is to define routing rules for traffic leaving the Virtual Cloud Network (VCN) subnet. It specifies which gateway or service should be used to route traffic to external destinations.
質問 # 30
Which statement best describes the default AuthZ behavior for users and groups in OCI Identity and Access Management?
- A. Access to resources is explicitly granted in policies; otherwise, it is denied by default.
- B. Users and groups are automatically granted access to all resources.
- C. Users and groups must request access from the administrator for each resource.
- D. Users and groups are granted access based on their roles without the need for policies.
正解：A
解説：
In OCI, users and groups must be explicitly granted access to resources through IAM policies. If access is not granted in a policy, it is denied by default, ensuring controlled access.
質問 # 31
In Oracle Cloud Infrastructure Block Volume Service, which feature enables you to increase the size of a block volume without any downtime?
- A. Volume Bursting
- B. Online Resizing
- C. Volume Elasticity
- D. Dynamic Volume Resizing
正解：B
解説：
Online Resizing allows you to increase the size of a block volume without any downtime. This feature enables you to scale up your storage capacity as needed without interrupting the services running on the block volume.
質問 # 32
What is the primary purpose of a Network Security Group (NSG) in the Oracle Cloud Infrastructure Networking service?
- A. To provide a private connection between a VCN and an on-premises network
- B. To connect a VCN to the public Internet
- C. To control traffic routing between VCNs
- D. To control traffic flow between specific resources within a VCN
正解：D
解説：
Network Security Groups (NSGs) act as virtual firewalls in OCI, controlling inbound and outbound traffic for specific resources within a VCN. You can define rules based on IPs, ports, and protocols.
質問 # 33
Which is NOT a type of instance offered by the Oracle Cloud Infrastructure Compute service?
- A. Dedicated Virtual Machine Host
- B. Virtual Machine
- C. Nano instance
- D. Bare Metal
正解：C
解説：
Nano instances are not offered by OCI. The compute service provides other instance types like Virtual Machines, Bare Metal, and Dedicated Hosts but does not include Nano instances.
質問 # 34
Which feature does the Oracle Cloud Infrastructure Compute service leverage for ensuring high availability of applications?
- A. Golden Gate
- B. Data Guard
- C. Real Application Clusters (RAC)
- D. Fault Domains
正解：D
解説：
Fault domains in Oracle Cloud Infrastructure are used to distribute instances across different physical hardware within an availability domain. This helps in ensuring high availability and fault tolerance by reducing the impact of hardware failures on instances.
質問 # 35
Which component of the Oracle Cloud Infrastructure Networking service allows resources in a VCN to access Oracle Cloud services without traversing the public Internet?
- A. Service Gateway
- B. Dynamic Routing Gateway (DRG)
- C. Network Address Translation (NAT) Gateway
- D. Internet Gateway
正解：A
解説：
A Service Gateway provides secure access to Oracle Cloud services from within a VCN without the need to traverse the public Internet. It facilitates private and efficient communication between resources and cloud services.
質問 # 36
Which type of workload is NOT suitable for using the Oracle Cloud Infrastructure File Storage service?
- A. Content management
- B. Big data and analytics
- C. Media processing
- D. Running small personal websites
正解：D
解説：
Running small personal websites typically do not require the scalability and performance capabilities provided by Oracle Cloud Infrastructure File Storage service. It may be more cost-effective and efficient to use other storage solutions for such workloads.
質問 # 37
Which networking component of OCI Virtual Cloud Network provides compute instances in a private subnet with outbound Internet access?
- A. Service Gateway
- B. Dynamic Routing Gateway (DRG)
- C. Network Address Translation (NAT)
- D. Internet Gateway
正解：C
解説：
Network Address Translation (NAT) allows compute instances in a private subnet to access the Internet while keeping their private IP addresses hidden. It provides outbound Internet access for instances in a private subnet by translating their private IP addresses to a public IP address.
質問 # 38
Which type of load balancing policy is supported by Oracle Cloud Infrastructure Load Balancer?
- A. Round Robin
- B. Weighted Round Robin
- C. Weighted Least Connection
- D. Random
正解：B
解説：
Weighted Round Robin is a load balancing policy that distributes traffic based on weights assigned to backend servers. It provides more control over traffic distribution, allowing higher-weighted servers to receive more requests.
質問 # 39
Why are availability domains within the same OCI region connected by a low-latency, high-bandwidth network?
- A. To ensure all domains share the same infrastructure
- B. To allow for high-availability connectivity and building replicated systems
- C. To reduce the need for encryption between domains
- D. To increase the likelihood of simultaneous failures
正解：B
解説：
The main purpose of connecting availability domains with a low-latency, high-bandwidth network is to enable high-availability connectivity and facilitate the building of replicated systems.
