• 24 bytes
• 14 bytes
• 20 bytes

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

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

In which two STP states is a port active and a MAC address learned? (Choose two.)

• Blocking
• Forwarding
• Disabled
• Learning

Your network connect to the Internet Through two different ISPs using EBGP. You must ensure that ISP1 is the primary path used for all traffic entering your network while using ISP2 as a backup path.In this scenario, which statement is correct?

• You should use a lower MED value on routes sent to ISP1.
• You should assign a higher local preference on routers that you are sending to ISP1.
• You should change the next hop for all routes sent to ISP2.
• You should your local AS number three times on routes that you are sending to ISP2.

Which statement is correct about trunk ports?

• Trunk ports mast have an IRB assigned to accept VLAN tagged traffic
• By default, trunk ports accept only VLAN tagged traffic
• By default, a trunk port can have only a single VLAN assigned
• Trunk ports must have an IRB assigned to accept untagged traffic.

Which device is used to separate collision domains?

• Switch
• Router
• Hub
• firewall

Which two statements describe BGP attributes? (Choose two.)

• BGP attributes help determine the best path to a destination.
• The origin attribute indicates the autonomous systems through which the route has traversed.
• BGP attributes are always optional.
• The AS path attribute indicates the autonomous systems through which the route has traversed.

You are adding a new EX4300 member switch to your existing EX4300 Virtual Chassis. However, the new member is not running the same Junos version as the other members.By default, what is the expected behavior in this scenario?

• The virtual Chassis will transition into a brain situation between the existing master Routing Engine and the switch running the different version.
• The new switch will be assigned a member ID and then placed in an inactive state.
• The new switch will be assigned a member ID and then placed in an inactive state.
• The new switch is not recognized by the virtual Chassis.
