What is the purpose of the native VLAN feature on the Juniper Networks EX Series Switches?
- A . It enables a trunk port to accept and forward untagged traffic.
- B . It restricts traffic on a trunk port to traffic that matches the configured native-vlan-id.
- C . It assigns a specific VLAN tag to all access ports that do not have a specific VLAN assigned.
- D . It enables an access port to accept and forward untagged traffic without a tag assigned.
Depending on the link type, OSPF sends link-state update packets to which two addresses? (Choose two.)
- A . 224.0.0.8
- B . 224.0.0.9
- C . 224.0.0.5
- D . 224.0.0.6
A host connected to interface ge-0/0/3 on your Juniper Networks EX Series Switch cannot reach another device in the same VLAN. The administrator wants to confirm that the switch has learned the MAC address of the host.
Which command should be used to accomplish this task?
- A . show interfaces terse
- B . show interfaces extensive
- C . show vlans
- D . show ethernet-switching table
Which two statements are correct about BGP local preference? (Choose two.)
- A . Local preference is advertised to EBGP peers.
- B . A local preference of 100 is the Junos default.
- C . A local preference of 0 means to drop the route.
- D . Local preference is used to direct outbound traffic within an AS to a specific peer.

You are asked to ensure that there will not be any unwanted STP topology changes affecting your root bridge placement because a rogue switch was introduced into the network at the access layer.
Referring to the exhibit, which interfaces will need to have root protection applied to accomplish this task?
- A . Place root protection on ge-0/0/6 and ge-0/0/8 on Switch-1 and Switch-2.
- B . Place root protection on ge-0/0/6 and ge-0/0/8 on Switch-1 only.
- C . Place root protection on ge-0/0/12 and ge-0/0/13 on Switch-1 and Switch-2.
- D . Place root protection on ge-0/0/6 and ge-0/0/8 on Switch-3 and Switch-4.

A network has three Juniper Networks EX Series Switches connected together. No changes have been made to the default spanning-tree configuration.
Referring to the exhibit, which statement is correct about the root bridge?
- A . Switch A will be elected because it has the lowest MAC address.
- B . When using RSTP, Switch B will be elected because it is the median MAC address.
- C . Switch C will be elected because it has the highest MAC address.
- D . The election cannot occur until bridge priority is configured on at least one switch.
You are creating an aggregated Ethernet bundle using LACP on your Juniper Networks EX Series device.
In this scenario, which statement is correct?
- A . You must use different LACP system priorities for each switch.
- B . LACP active mode is required on both sides of the bundle.
- C . By default, LACP is in active mode on aggregated Ethernet interfaces.
- D . LACP active mode is required on at least one side of the bundle.
You are configuring a GRE tunnel between Router A (192.168.1.1) and Router B (192.168.2.1) to connect two isolated networks. The tunnel interfaces (gr-0/0/0) need to support IPv4 traffic.
In this scenario, which configuration ensures the tunnel endpoints are correctly defined and reachable?
- A . set interfaces gr-0/0/0 unit 0 tunnel source 192.168.1.1 destination 192.168.2.1
- B . set interfaces gr-0/0/0 unit 0 family inet address 192.168.1.1
- C . set interfaces gr-0/0/0 unit 0 family inet6
- D . set interfaces gr-0/0/0 unit 0 tunnel destination 192.168.2.1
You have configured an aggregate route for prefix 10.20.0.0/22 with three contributing routes:
– 10.20.0.0/24
-10.20.1.0/24
– 10.20.2.0/24
A packet arrives destined to 10.20.3.100.
In this scenario, which action does the router take?
- A . It forwards the packet using the next hop defined for the aggregate route.
- B . It forwards the packet using the next hop for the contributing route with the lowest preference.
- C . It drops the packet and send an ICMP network unreachable message to the source.
- D . It silently drops the packet and does not send an ICMP network unreachable message to the source.
Which statement describes the purpose of an integrated routing and bridging (IRB) interface on a Juniper Networks EX Series Switch?
- A . It performs Layer 2 switching across multiple VLANs.
- B . It provides a Layer 3 gateway for a specific VLAN.
- C . It replaces the need for trunk ports.
- D . It removes the need for routing instances.
