A company must run a legacy application that requires a specific older version of a Linux kernel and a non-standard kernel module. The application is critical and cannot tolerate any interference from other workloads on the same host. Which deployment approach is most appropriate?

Container with the required kernel module loaded on the host

Container with a user-space emulation of the kernel module

Virtual machine with its own guest OS and kernel

Virtual machine but with a shared kernel from the host

Which use case is most appropriate for containers?

Deploying microservices that need to scale independently

Providing hardware-level isolation for untrusted code

Running multiple different operating systems on a single host

Running legacy applications that require a specific OS version

Why are containers generally more portable across different environments than virtual machines?

They package the application and dependencies, and run on any host with a compatible kernel.

They include a hypervisor that abstracts the hardware.

They are tied to the hypervisor's hardware abstraction layer.

They require the same guest OS on every host.

A company wants to deploy the same application to an on-premises VMware cluster and to a public cloud provider that uses a different hypervisor. The application is a standard Linux web server. Which approach minimizes the effort to maintain identical environments across both locations?

Create a VM template in VMware and convert it for the cloud provider

Maintain two separate VM templates, one for each environment

Build a container image and run it on both the VMware cluster and the cloud provider

Use a configuration management tool to provision VMs in both environments

A company is hosting multiple applications for different clients on the same physical server. Each client's application must be isolated so that a vulnerability in one application cannot compromise another client's data. The applications are all Linux-based and have no kernel-specific requirements. Which technology provides the strongest isolation while still being resource-efficient?

Containers with user namespaces

Containers with resource limits

Virtual machines but with a shared kernel

Virtual machines with a hypervisor

Container Versus Virtual Machine JN0-214 Practice Questions (Page 1)

Part of the Cloud Virtualization domain, which makes up ~26% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~9–16 in this domain), expect 1–2 from this objective — we provide 24 practice questions to prepare you well beyond it.
