You work for a medium sized ISP and there have been several attacks of the DNS configuration
recently. You are particularly concerned with DNS Spoofing attacks. You have a few older
machines that define the storage of Resource Records (RR) based on the TTL of name mapping
information. If an attacker sends fake mapping information to the DNS Server, with a high TTL,
which type of DNS Spoofing is this?

A.
DNS Server Compromise

B.
DNS Cache Poisoning

C.
Spoofing the DNS Response

D.
DNS Source-Router Spoof

E.
IXFR Source-Spoof
