30. Which two statements about BPDU protection are correct? (Choose two.)

31. 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?

32. Exhibit.

You are attempting to set up VRRP with R1 and R2 being participating members. You want R1 to be the master router and R2 to be the backup router with the virtual router they create being at address 172.25.100.1. The virtual router is not pinging from either User A or User B.
