Question No: 11
Which tunnel type can be used with encryption to provide security for IPv6 over IPv4?
Question No: 12
Refer to the exhibit.
If the route to 10.1.1.1 is removed from the R2 routing table, which server becomes the master NTP server?
B. the NTP server at 10.3.3.3
C. the NTP server at 10.4.4.4
D. the NTP server with the lowest stratum number
NTP uses a concept called u201cstratumu201d that defines how many NTP hops away a device is from an authoritative time source. For example, a device with stratum 1 is a very accurate device and might have an atomic clock attached to it. Another NTP server that is using this stratum 1 server to sync its own time would be a stratum 2 device because itu2019s one NTP hop further away from the source. When you configure multiple NTP servers, the client will prefer the NTP server with the lowest stratum value.
