• Question 68:

  Routet-1 and Router-2 must connect through the Internet using a tunneling technology. Hosts that are connected to Router-1 and Router-2 will be sending traffic up to 1500 bytes. The maximum segment size that is supported across the path is 1520 bytes.

  Which tunneling technology will allow this communication to take place?

  A. IP-IP tunnel

  B. GRE tunnel

  D. IPsec VPN transport mode

  Correct Answer: A

• Question 69:

  Your router is learning the 172.25.11.0/24 prefix from both the BGP and OSPF protocols. A routing policy is configured on your device to advertise the prefix to an established BGP peer but the peer is not receiving the prefix. You want to allow the prefix to be advertised to the BGP peer.

  What should you do on this router to satisfy this requirement?

  A. Enable the automatic removal of peer AS information from the prefix.

  B. Enable the advertisement of inactive BGP routes.

  C. Enable the automatic removal of private AS numbers from the prefix.

  D. Enable the automatic refreshing of BGP routes.

  Correct Answer: B

  Which two statements about the default load-balancing behavior for the Junos OS are correct? (Choose two.)

  A. By default, the Junos OS performs a per-packet load-balancing operation.

  B. By default, the Junos OS installs multiple equal-cost next hops in the forwarding table for a destination prefix.

  C. By default, the Junos OS selects one of the equal-cost next hops for received destination prefixes.

  D. By default, all Packet Forwarding Engine slots are assigned the same hash value on the Junos device.

  Correct Answer: CD
