Question 3

You are asked to connect an IP phone and a user computer using the same interface on an EX Series switch. The traffic from the computer does not use a VLAN tag, whereas the traffic from the IP phone uses a VLAN tag.
Which feature enables the interface to receive both types of traffic?

Question 4

Referring to the exhibit, what will be the IS-IS adjacency result of the configurations?

A. No IS-IS adjacencies will form. B. A level 1 IS-IS adjacency will form. C. A level 1 and level 2 IS-IS adjacency will form. D. A level 2 IS-IS adjacency will form.

Correct Answer: A

Question 5

You deployed a new EX Series switch with DHCP snooping enabled and you do not see any entries in the snooping databases for an interface. Which two Juniper configurations for that interface caused this issue? (Choose two.)

Question 6

Which statement is correct about how a Juniper Networks EX Series Switch learns MAC addresses?

A. The switch learns MAC addresses by polling connected hosts periodically. B. The switch learns source MAC addresses from received frames and records the ingress interface and timestamp. C. The switch adds destination MAC addresses to the bridge table after forwarding frames. D. The switch learns MAC addresses only after a spanning-tree topology change occurs.

Question 9

Which two statements about DHCP snooping are correct? (Choose two.)

A. DHCP snooping uses ARP to add statically defined IP addresses to its database. B. By default, the Junos OS treats access ports as trusted and trunk ports as untrusted. C. DHCP snooping inspects all DHCP packets on untrusted ports. D. The DHCP database maps IP addresses, MAC addresses, and the associated VLAN.
