During the name resolution process, which step does the resolver perform first to resolve a DNS name?
  1. Read from the Hosts file.
  2. Broadcast the local subnet.
  3. Check the local cache.
  4. Query the local DNS server.
Explanation
Answer - C - During the name resolution process, the resolver checks the local cache first.

Key Takeaway: When the DNS Client service on the client computer begins the query process, the client contacts its preferred DNS server with a query. This name server checks its cache and zones for the answer. If it does not find the answer, it contacts a root server with the query. If the root server does not know the answer, it responds with a referral to a server authoritative for the .com domain.
