Question 32

Your network has an unmanaged switch between the hosts and your EX Series switch. After the traffic enters the EX Series switch, each host must be on a separate VLAN.

How would you accomplish this task?

Configure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs.

Configure an output firewall filter on interface ge-0/0/1 to match the destination MAC or IP address of the hosts to assign the VLANs.

Configure interface ge-0/0/3 to a mode trunk to assign the VLANs.

Configure VSTP on interface ge-0/0/1 to assign the VLANs.

Which two statements are true? (Choose two.)

Before the formation of the rendezvous-point tree, a join message is sent from R1 to R3.

Before the formation of the rendezvous-point tree, an IGMP is sent from the Receiver to R1.

Before the formation of the rendezvous-point tree, an IGMP is sent from the Source to R5.

Question 35

When using wide metrics, which two statements about route advertisement between IS-IS levels are correct? (Choose two.)

Level 1 and Level 2 routers do not advertise Level 2 routes into the Level 1 area by default.

Level 1 routes are advertised to Level 2 routers by default.

If wide-metrics-only is configured, Level 1 routes are not advertised to Level 2 routers by default.

The routes only timeout after 24 hours.

The routes remain in the table until the device is rebooted.

The routes remain in the table until the routing daemon is restarted.

Question 38

Your EX Series switch has IP telephones and computers connected to a single switch port. You are considering implementing the voice VLAN feature to help with this setup.

In this scenario, which two statements are correct? (Choose two.)

The voice VLAN feature must be used with LLDP-MED to associate VLAN ID and 802.1p values with the traffic.

The interfaces must be configured as access ports.
