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

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.
Referring to the exhibit, what must be done to correct the problem?
- A . The VRRP group value on R1 and R2 must match.
- B . A VRRP authentication type value is needed on R1 and R2.
- C . A VRRP policy is needed on R1 and R2.
- D . The VRRP priority value on R1 and R2 must match
