A network administrator has configured a virtual switch named VS-CORE on a Junos device. After committing the configuration, the administrator wants to verify which interfaces are members of VS-CORE and their associated VLANs. Which operational command displays this information?

A Junos router has a virtual switch named VS1 with VLANs 10 and 20. The engineer needs to provide inter-VLAN routing, but the router's IRB interface is already in use by another routing instance. What is a valid alternative to enable routing between VLAN 10 and VLAN 20?

Use a firewall filter to route between the VLANs.

Use a static route in the default routing instance.

Use a separate routing instance of type virtual-switch for each VLAN and route between them.

Use a logical router and assign the VLANs to it.

A service provider is designing a network using virtual switches on a Junos MX router. The design must support a large number of customers, each with a few VLANs. What is a key best practice to follow when deploying virtual switches in this scenario?

Assign a unique virtual switch to each customer to ensure Layer 2 isolation.

Place all customer VLANs in the default routing instance and use firewall filters for isolation.

Use a single virtual switch for all customers to simplify configuration.

Avoid using virtual switches and rely solely on VLANs for isolation.

Which configuration is required to route between VLANs in a virtual switch?

Assign a public IP address to each VLAN

Configure a default route in the routing instance

Enable routing protocols on the virtual switch

Create an IRB interface for each VLAN and assign IP addresses

What is a common limitation of virtual switches in Junos?

They cannot be used with IRB interfaces

They require a separate physical switch for each virtual switch

They are limited by the number of VLANs and interfaces supported by the hardware

They cannot be used in service provider networks

Virtual Switches JN0-364 Practice Questions (Page 1)

Part of the Layer 2 Bridging and VLANs domain, which makes up ~11% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–1 from this objective — we provide 19 practice questions to prepare you well beyond it.
