Which of the following statements are true regarding domain name service (DNS)? One of the key requirements of DNS is that it needs to hold information that belongs to different institutions and the correctness of that information can only be validated by those institutions. | DNS holds information as resource records that have very long life times compared to the time needed to find and access them. |DNS needs to provide guarantees on very short response times for accesses. A compromised DNS (i.e., a DNS with fake name to resource bindings) is not a security problem for the Internet users.
