A company has two VLANs, VLAN 10 and VLAN 20, on a single Juniper EX switch. The administrator needs to enable communication between the two VLANs without adding any additional hardware. What should the administrator configure?

A single VLAN with both subnets assigned to it.

A trunk port connecting the two VLANs.

A routed VLAN interface (RVI) for each VLAN with IP addresses in different subnets.

A static route between the two VLANs.

A switch has been configured with VLAN 50 and interface ge-0/0/5 assigned to it. The administrator wants to verify that the interface is actually passing traffic for VLAN 50. Which command should the administrator use?

show interfaces ge-0/0/5 extensive

show configuration interfaces ge-0/0/5

Inter-VLAN routing is not working. You suspect a firewall filter is blocking traffic. Which command would you use to check for firewall filters applied to the IRB interface?

show configuration interfaces irb
