| Question | Answer |
| If a DNS server does not host a primary or secondary containing the resource records that are requested by a DNS client, what does it then do by default? | It contacts the root hints |
| When does a DNS server use a forwarder? | If it receives a request for which it is not authorative |
| Where are forwarders commonly used for? | Internet name resolution |
| What is conditional forwarding? | When a conditional forwarder is configured, all queries for a specific domain, are forwarded to a specified DNS server. |
| What are stub zones? | A stub zone contains the information for DNS servers of a different domain, without synchronizing the entire DNS zone. |
| Which records are synchronized with a stub zone? | - Name server (NS) records - Host (A) records for the name servers - Start of authority (SOA) records |
| When would you use a stub zone instead of a conditional forwarder? | If the DNS infrastructure is likely to change. |
