Containers share the host operating system's kernel, leading to quicker startup times and lower overhead compared to virtual machines. They offer more agility and resource efficiency, making them suitable for scalable applications.
質問 # 22
Which networking component of OCI Virtual Cloud Network provides compute instances in a private subnet with outbound Internet access?
- A. Internet Gateway
- B. Dynamic Routing Gateway (DRG)
- C. Network Address Translation (NAT)
- D. Service 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 # 23
Which is NOT a component of an Identity and Access Management (IAM) policy statement in Oracle Cloud Infrastructure?
- A. Resource-type
- B. Action Verb
- C. Data backup frequency
- D. Location
正解：C
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 # 24
Which workload type is NOT optimized for Oracle Autonomous Database on Shared Exadata Infrastructure?
- A. Data warehousing
- B. Mixed workloads
- C. High-performance computing
- D. Transaction processing
正解：C
解説：
High-performance computing (HPC) typically involves complex calculations and processing, which are not optimized for Oracle Autonomous Database on Shared Exadata Infrastructure. HPC often requires specialized hardware and configurations for optimal performance.
質問 # 25
What is an availability domain in Oracle Cloud Infrastructure?
- A. A type of encrypted traffic
- B. A set of virtual cloud networks
- C. One or more data centers located within a region
- D. A localized geographical area
正解：C
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 # 26
How are compartment quotas applied in Oracle Cloud Infrastructure?
- A. On a per-region basis
- B. Globally, across all compartments
- C. On a per-tenancy basis
- D. On a per-compartment basis
正解：D
解説：
Compartment quotas are applied on a per-compartment basis in Oracle Cloud Infrastructure. Each compartment has its own set of quota limits for resources and services that are enforced within that compartment.
質問 # 27
What is an availability domain in Oracle Cloud Infrastructure?
- A. A type of encrypted traffic
- B. A set of virtual cloud networks
- C. One or more data centers located within a region
- D. A localized geographical area
正解：C
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 # 28
In Oracle Cloud Infrastructure, what does the Universal Credits pricing model allow customers to do?
- A. Pay only for services they use with no upfront commitment
- B. Receive a fixed amount of resources for a specific price
- C. Use prepaid credits for any eligible cloud service
- D. Pay a fixed price for all services
正解：C
解説：
Using prepaid credits for any eligible cloud service is a feature of the Universal Credits pricing model in Oracle Cloud Infrastructure. Customers can allocate their prepaid credits to various services based on their needs and usage.
質問 # 29
What is the primary purpose of fault domains in Oracle Cloud Infrastructure?
- A. To ensure all instances are on the same physical hardware
- B. To connect availability domains with low latency
- C. To distribute instances across different physical hardware within an availability domain
- D. To handle encryption of traffic between instances
正解：C
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 # 30
Why are availability domains within the same OCI region connected by a low-latency, high-bandwidth network?
- A. To increase the likelihood of simultaneous failures
- B. To ensure all domains share the same infrastructure
- C. To allow for high-availability connectivity and building replicated systems
- D. To reduce the need for encryption between domains
正解：C
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.
