What is the primary purpose of inter-VLAN routing?

To provide redundancy for VLANs in case of a link failure

To segment a network into multiple broadcast domains

To filter traffic between VLANs based on security policies

To allow devices in different VLANs to communicate with each other

A router is configured for router-on-a-stick with subinterfaces ge-0/0/0.10 (192.168.10.1/24) and ge-0/0/0.20 (192.168.20.1/24). The switch trunk allows both VLANs. Hosts in VLAN 10 can ping 192.168.10.1, but cannot ping hosts in VLAN 20. What should you verify on the router?

That the hosts in VLAN 20 have a default gateway of 192.168.10.1.

That the physical interface ge-0/0/0 is configured as a trunk.

That ge-0/0/0.20 has the correct VLAN tag (20) and an IP address in the 192.168.20.0/24 subnet.

That the switch port is configured as an access port in VLAN 10.

A small office has a single Juniper EX2300 switch and a Juniper SRX router. The switch has VLAN 10 (192.168.10.0/24) for staff and VLAN 20 (192.168.20.0/24) for guests. The SRX has one physical interface, ge-0/0/0, connected to the switch. You must enable communication between the two VLANs using the router. What should you configure on the SRX?

Assign a single IP address (192.168.10.1/24) to ge-0/0/0 and add a static route for 192.168.20.0/24 pointing to the switch's management IP.

Create two subinterfaces (ge-0/0/0.10 and ge-0/0/0.20) with 802.1Q VLAN tags 10 and 20, assign IP addresses from each VLAN subnet, and configure the switch port as a trunk.

Create two IRB interfaces (irb.10 and irb.20) on the SRX, assign IP addresses from each VLAN subnet, and configure the switch port as an access port in VLAN 10.

Configure ge-0/0/0 as a trunk port with native VLAN 10, and create a single subinterface ge-0/0/0.20 tagged with VLAN 20.

Which two methods are commonly used to perform inter-VLAN routing?

VLAN trunking and port mirroring

Static routing and dynamic routing

Spanning Tree Protocol and link aggregation

Router-on-a-stick and Layer 3 switching

Which command is used to create an SVI on a Juniper EX Series switch?

set interfaces vlan unit 0 family inet address 192.168.1.1/24

set interfaces ge-0/0/1 unit 0 family ethernet-switching

set routing-options static route 0.0.0.0/0 next-hop 192.168.1.1

Inter-VLAN Routing JN0-352 Practice Questions (Page 3)

Part of the Layer 2 Switching and VLANs domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–1 from this objective — we provide 17 practice questions to prepare you well beyond it.
