Layer 2 Switching And VLANs

An administrator needs to view the MAC address learning table on an EX Series switch to verify which switchport a specific server is connected to. Which operational command should be used?

An administrator needs to create a VLAN named 'voice' with a VLAN ID of 50 on a Junos EX Series switch. Which configuration path achieves this?

An administrator is configuring a new EX Series switch running Junos OS and needs to assign an access port to VLAN finance. Which configuration hierarchy is used to assign an interface to a specific VLAN?

You are troubleshooting a connectivity issue between an EX4300 switch access port and an end-host. The port is configured as an access port for VLAN 100, but the host cannot communicate. You run 'show ethernet-switching interface ge-0/0/1' and notice the port status is down/down. Which underlying reason most likely explains this state?

An enterprise network uses private VLANs. A server connected to an isolated port needs to send traffic out of the primary VLAN. Which statement accurately describes how traffic forwarding operates for an isolated port in Junos?

An administrator configures a new VLAN ID 300 on an EX Series switch but forgets to assign any interfaces to it. What is the operational status of this VLAN?

An administrator runs 'show vlans' and notices that a particular VLAN has the status 'Active' but no interfaces listed under it. What does this indicate?

An administrator needs to delete an entire VLAN configuration named 'guest' along with its VLAN ID and associated properties. Which configuration command should be executed?

You are reviewing the configuration of an EX Series switch and notice that interface ge-0/0/15 is configured with 'interface-mode access' but has no explicit 'vlan members' statement defined. Which VLAN does the interface default to?

An administrator is configuring VLANs on a Junos EX Series switch. Which TWO tasks must be performed to successfully assign a physical interface as an access port for a newly created VLAN? (Choose two.)

An engineer is configuring a trunk port on an EX Series switch and needs to ensure that untagged and priority-tagged frames are handled correctly. Which TWO configuration actions are required? (Choose two.)

An enterprise network design requires implementing private VLANs (PVLANs) on an EX Series switch. Which THREE components or port types are characteristic of a private VLAN architecture? (Choose three.)

You are troubleshooting a Layer 2 connectivity problem where a trunk port is dropping tagged traffic for VLAN 50. Which TWO configuration checks should be performed? (Choose two.)

An administrator is configuring Selective QinQ on an EX Series switch using VLAN translation. Which THREE components are required to successfully rewrite inner and outer VLAN tags? (Choose three.)

An engineer is deploying Private VLANs on an EX Series switch and needs to verify proper operational status and traffic isolation. Which THREE tasks or verification checks should be performed? (Choose three.)

An operator executes the command 'show bridge mac-table' on an EX Series switch running Junos OS. Which information is displayed in the output of this command?

Which THREE parameters are typically verified when troubleshooting a missing MAC address entry in the bridge table of a Juniper switch? (Choose three.)

When configuring Private VLANs (PVLANs) on Juniper EX Series switches, which TWO types of ports are defined within the architecture? (Choose two.)

You are configuring a Private VLAN (PVLAN) on an EX Series switch to isolate hosts within a DMZ segment while allowing them to reach a shared gateway. Which TWO statements correctly describe the behavior of PVLAN port types in this scenario? (Choose two.)

An EX4300 switch is configured with a trunk port that carries VLAN 10 and VLAN 20. The trunk is connected to a third-party switch that uses a native VLAN of 1 for untagged traffic. You notice that untagged frames from the third-party switch are being dropped on the EX4300. Which configuration change resolves this issue?
