Dockerd is the Docker daemon that acts as the primary user interface for Docker. Docker cl is not a valid name for any Docker component.Cri-o is another container runtime that implements the Kubernetes Container Runtime Interface (CRI) to enable using OCI (Open Container Initiative) compatible runtimes

Answer : C

CN2 (Cranial Nerve II), also known as the optic nerve, controls the special sense of vision.It transmits visual information from the retina to the vision centers of the brain78. Two functions that CN2 provides are:

It provides enhanced networking capabilities to private clouds78.It transmits special afferent impulses of light to the brain and is involved in several reflex arcs related to the ocular system7.

It provides an orchestration solution for VMs and containers78.It is a unique structure that functions as the bridge between the retinal layer of the eyes and the visual cortex of the brain7. Reference from Juniper site:Kenhub,Geeky Medics

Answer : B

In a CN2 deployment using Kubernetes as the orchestrator, the vRouter agent is contained in the worker node. The vRouter agent is responsible for managing the forwarding plane on each node in a Contrail cluster. It interacts with the kernel to manage the services and interfaces within the virtual networks.

Answer : C

OpenStack's networking service is known as Neutron. Neutron provides a scalable, API-driven, web services-based model for network connectivity as a service. It is designed to manage and configure networking services for both simple and complex network topologies. Neutron allows users to create their own networks, control traffic and connect servers and devices to one or multiple networks.
