Match the description about virtual systems and VPN instances.

Correct Answer:

Explanation:
1. Virtual System # Services and routes can be isolated.
* A virtual system (VS)in Huawei firewalls is afully isolated security instancewithin a single physical firewall.
* Each virtual system hasseparate services, routing tables, policies, and security rules, ensuring full isolation between different users or tenants.
2. VPN Instance # Only route isolation can be implemented.
* AVPN instance (VRF - Virtual Routing and Forwarding)providesroute isolationfor different customer networks butdoes not isolate services or security policies.
* This is typically used inMPLS VPN deploymentswhere different customers share the same physical device but need isolated routing tables.
3. VPN Instance # VPN instances are automatically generated.
* In someMPLS VPNorSDN-managed networks, VPN instances can beautomatically createdwhen customer configurations are pushed via controllers.
* Dynamic routing protocols (e.g., BGP/MPLS VPN) can automatically generateVRF instancesbased on network policies.
4. Virtual System # An instance needs to be manually created.
* Unlike VPN instances,virtual systems must be manually createdby an administrator on the firewall.
* Each virtual system functions as acompletely independent firewall, requiring manual configuration of interfaces, policies, and routing settings.
