Correct Answer: A

Question 2

Question 6

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?

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

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

C. 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.

D. 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.

Question 7

You are authenticating user devices connected to your ex Series switch. You have 802.1X and MAC RADIUS configured for all ports. A user is complaining about the time it takes to connect their non- 802.1X device on ge-0/0/15 using MAC RADIUS authentication.
Referring to the exhibit, what should be done to accelerate the authentication process?

A. Configure the no-reauthentication feature for 802.1X on ge-0/0/15

B. Change the 802.1X retry attempts value to 5 on ge-0/0/15

C. Change the supplicant mode to multiple on ge-0/0/15

D. Configure the restrict feature for MAC RADIUS on ge-0/0/15.

Correct Answer: C

Question 8

You are deploying new Juniper EX Series switches in a network that currently is using Cisco's Per- VLAN spanning tree plus (PVST+) and you must provide compatibility with this environment.
Which spanning tree protocol do you deploy in this scenario?

B. MSTP

C. VSTP

D. STP
