ネットワーク管理者は、外部 DNS レコードがホストされる場所を変更する必要があります。このタスクを実行するには、管理者がレジストラで変更する必要があるレコードは次のうちどれですか?
正解:A
NS stands for Name Server, and it is a DNS record that specifies which servers are authoritative for a domain. The registrar is the entity that manages the domain registration and delegation, and it maintains the NS records for each domain. To change where the outside DNS records are hosted, the network administrator needs to change the NS records at the registrar to point to the new DNS servers that will host the outside DNS records.
