질문 # 15
Which two statements are correct about cloud computing? (Choose two.)
정답:B,C
설명:
Cloud computing is a model for delivering IT services where resources are provided over the internet on-demand. Let's analyze each statement:
A . Cloud computing eliminates operating expenses.
Incorrect: While cloud computing can reduce certain operating expenses (e.g., hardware procurement, maintenance), it does not eliminate them entirely. Organizations still incur costs such as subscription fees, data transfer charges, and operational management of cloud resources. Additionally, there may be costs associated with training staff or migrating workloads to the cloud.
B . Cloud computing has the ability to scale elastically.
Correct: Elasticity is one of the key characteristics of cloud computing. It allows resources (e.g., compute, storage, networking) to scale up or down automatically based on demand. For example, during peak usage, additional virtual machines or storage can be provisioned dynamically, and when demand decreases, these resources can be scaled back. This ensures efficient resource utilization and cost optimization.
C . Cloud computing increases the physical control of the data resources.
Incorrect: Cloud computing typically reduces physical control over data resources because the infrastructure is managed by the cloud provider. For example, in public cloud models, the customer does not have direct access to the physical servers or data centers. Instead, they rely on the provider's security and compliance measures.
D . Cloud computing allows access to data any time from any location through the Internet.
Correct: One of the core advantages of cloud computing is ubiquitous access. Users can access applications, services, and data from anywhere with an internet connection. This is particularly beneficial for remote work, collaboration, and global business operations.
JNCIA Cloud Reference:
The Juniper Networks Certified Associate - Cloud (JNCIA-Cloud) curriculum highlights the key characteristics of cloud computing, including elasticity, scalability, and ubiquitous access. These principles are foundational to understanding how cloud environments operate and how they differ from traditional on-premises solutions.
For example, Juniper Contrail, a software-defined networking (SDN) solution, leverages cloud elasticity to dynamically provision and manage network resources in response to changing demands. Similarly, the ability to access cloud resources remotely aligns with Juniper's focus on enabling flexible and scalable cloud architectures.

질문 # 16
Which two CPU flags indicate virtualization? (Choose two.)
정답:A,D
설명:
CPU flags indicate hardware support for specific features, including virtualization. Let's analyze each option:
A . lvm
Incorrect: LVM (Logical Volume Manager) is a storage management technology used in Linux systems. It is unrelated to CPU virtualization.
B . vmx
Correct: The vmx flag indicates Intel Virtualization Technology (VT-x), which provides hardware-assisted virtualization capabilities. This feature is essential for running hypervisors like VMware ESXi, KVM, and Hyper-V.
C . xvm
Incorrect: xvm is not a recognized CPU flag for virtualization. It may be a misinterpretation or typo.
D . kvm
Correct: The kvm flag indicates Kernel-based Virtual Machine (KVM) support, which is a Linux kernel module that leverages hardware virtualization extensions (e.g., Intel VT-x or AMD-V) to run virtual machines. While kvm itself is not a CPU flag, it relies on hardware virtualization features like vmx (Intel) or svm (AMD).
Why These Answers?
Hardware Virtualization Support: Both vmx (Intel VT-x) and kvm (Linux virtualization) are directly related to CPU virtualization. These flags enable efficient execution of virtual machines by offloading tasks to the CPU.
JNCIA Cloud Reference:
The JNCIA-Cloud certification emphasizes understanding virtualization technologies, including hardware-assisted virtualization. Recognizing CPU flags like vmx and kvm is crucial for deploying and troubleshooting virtualized environments.
For example, Juniper Contrail integrates with hypervisors like KVM to manage virtualized workloads in cloud environments. Ensuring hardware virtualization support is a prerequisite for deploying such solutions.

질문 # 17
Which Docker component builds, runs, and distributes Docker containers?
정답:C
설명:
Docker is a popular containerization platform that includes several components to manage the lifecycle of containers. Let's analyze each option:
A . dockerd
Correct: The Docker daemon (dockerd) is the core component responsible for building, running, and distributing Docker containers. It manages Docker objects such as images, containers, networks, and volumes, and handles requests from the Docker CLI or API.
B . docker registry
Incorrect: A Docker registry is a repository for storing and distributing Docker images. While it plays a role in distributing containers, it does not build or run them.
C . docker cli
Incorrect: The Docker CLI (Command Line Interface) is a tool used to interact with the Docker daemon (dockerd). It is not responsible for building, running, or distributing containers but rather sends commands to the daemon.
D . container
Incorrect: A container is an instance of a running application created from a Docker image. It is not a component of Docker but rather the result of the Docker daemon's operations.
Why dockerd?
Central Role: The Docker daemon (dockerd) is the backbone of the Docker platform, managing all aspects of container lifecycle management.
Integration: It interacts with the host operating system and container runtime to execute tasks like building images, starting containers, and managing resources.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers Docker as part of its containerization curriculum. Understanding the role of the Docker daemon is essential for managing containerized applications in cloud environments.
For example, Juniper Contrail integrates with Docker to provide advanced networking and security features for containerized workloads, relying on the Docker daemon to manage containers.

질문 # 18
Which Linux protection ring is the least privileged?
정답:D
설명:
In Linux systems, the concept of protection rings is used to define levels of privilege for executing processes and accessing system resources. These rings are part of the CPU's architecture and provide a mechanism for enforcing security boundaries between different parts of the operating system and user applications. There are typically four rings in the x86 architecture, numbered from 0 to 3:
Ring 0 (Most Privileged): This is the highest level of privilege, reserved for the kernel and critical system functions. The operating system kernel operates in this ring because it needs unrestricted access to hardware resources and control over the entire system.
Ring 1 and Ring 2: These intermediate rings are rarely used in modern operating systems. They can be utilized for device drivers or other specialized purposes, but most operating systems, including Linux, do not use these rings extensively.
Ring 3 (Least Privileged): This is the least privileged ring, where user-level applications run. Applications running in Ring 3 have limited access to system resources and must request services from the kernel (which runs in Ring 0) via system calls. This ensures that untrusted or malicious code cannot directly interfere with the core system operations.
Why Ring 3 is the Least Privileged:
Isolation: User applications are isolated from the core system functions to prevent accidental or intentional damage to the system.
Security: By restricting access to hardware and sensitive system resources, the risk of vulnerabilities or exploits is minimized.
Stability: Running applications in Ring 3 ensures that even if an application crashes or behaves unexpectedly, it does not destabilize the entire system.
JNCIA Cloud Reference:
The Juniper Networks Certified Associate - Cloud (JNCIA-Cloud) curriculum emphasizes understanding virtualization, cloud architectures, and the underlying technologies that support them. While the JNCIA-Cloud certification focuses more on Juniper-specific technologies like Contrail, it also covers foundational concepts such as virtualization, Linux, and cloud infrastructure.
In the context of virtualization and cloud environments, understanding the role of protection rings is important because:
Hypervisors often run in Ring 0 to manage virtual machines (VMs).
VMs themselves run in a less privileged ring (e.g., Ring 3) to ensure isolation between the guest operating systems and the host system.
For example, in a virtualized environment like Juniper Contrail, the hypervisor (e.g., KVM) manages the execution of VMs. The hypervisor operates in Ring 0, while the guest OS and applications within the VM operate in Ring 3. This separation ensures that the VMs are securely isolated from each other and from the host system.
Thus, the least privileged Linux protection ring is Ring 3 , where user applications execute with restricted access to system resources.
