With forwarders and/or conditional forwarders configured,the DNS server attempts to resolve DNS queries in this order:
1)From traditional forwarders (if configured)
2)From conditional forwarders (if configured and the domain name matches)
3)From locally stored zone resource records
4)From the DNS cache
5)Recursively by using root hints (only if no traditional forwarder is configured)
This list has been slightly rearranged.What entry number should be switched in order to make this list accurate?
A)Switch #2 with #1
B)Switch #4 with #5
C)Switch #3 with #4
D)Switch #5 with #3

The current order suggests that the DNS server would first look for queries from traditional forwarders, followed by conditional forwarders. Then it would look for locally stored zone resource records, DNS cache, and finally recursively using root hints if no traditional forwarder is configured. However, it is more accurate to say that the DNS server would first look for queries from traditional forwarders, followed by locally stored zone resource records. Then it would check the DNS cache and attempt to resolve queries recursively using root hints. Only after these options have been exhausted, it would check for conditional forwarders. Therefore, the entry number that needs to be switched to make the list accurate is option C: switch #3 with #4.
