Across
- 3. A DNS server that keeps a database of addresses of other DNS servers managing top-level domain names
- 7. A computer making a DNS query
- 11. A record containing an alias for another record that enables you to refer to the same resource with different names yet maintain only one host record
- 12. A type of DNS resource record that is used to resolve a known IP address to a hostname
- 14. A resource record in a DNS zone that consists of a hostname and an IPv6 address
- 21. A distributed hierarchical database composed mainly of a computer name and IP address pair
- 22. A resource record in a DNS zone taht consists of a hostname and an IPv4 address
- 23. A DNS server that maintains addresses of other DNS servers taht are authoritative for 2nd-level domains
- 25. A resource record in a DNS zone that consists of a hostname and an IP address. also called an A record or AAAA record depending on whether the IP address is IPv4 or IPv6
- 26. The entire DNS tree that defines the structure of the names used to identify resources in network domains. it consists of a root name (defined as a period), top-level domains, 2nd-level domains, optionally one or more subdomains, and hostnames separated by periods.
- 27. A DNS server to which other DNS servers send requests that can't resolve themselves.
- 31. analytic event An event that is created every time DNS sends and receives information
- 32. An operation that copies all or part of a zone from one DNS server to another and occurs as a result of a secondary server requesting the transfer from another server
- 33. A DNS containing Pointer (PTR) records that map IP addresses to names; it's named with the IP network address (IPv4 or IPv6) of the computer whose records it contains
Down
- 1. An assigned name that is associated with an IP address, so when a client looks up the name www.bbw.com, the DNS server returns an IP address
- 2. A DNS zone containing a read/write master master copy of all resource records for the zone; this zone is authoritative for the zone
- 4. A list of name servers preconfigured on Windows DNS servers that point to Internet root servers, which are DNS servers located on the Internet and managed by Internet Assigned Numbers Authority (IANA)
- 5. The full domain name for a host that specifically identifies in within the hierarchy of the Domain Name System (DNS)
- 6. Caching-only DNS server
- 8. An audit event that tracks changes to a DNS server, such as when zone or resource changes are made, and is enabled by default
- 9. A query in which the DNS server processes the query until it responds with an address that satisfies the query or with an "IDK" message. The process might require the DNS server to query several additional DNS servers
- 10. A feature that provides a way for IT admins to add single-label names (computer names that don't use a domain suffix, such as NetBiOS names) to DNS, thereby allowing client computers to resolve these names without including a DNS suffix in the query
- 13. A grouping of DNS information that represents one or more domains and possibly subdomains
- 15. A DNS name-registering process whereby computers in the domain can register or update their own DNS records
- 16. Data in a DNS database containing information about network resources, such as hostnames, other DNS servers, and services; each record identified by a letter code
- 17. A DNS server that maintains addresses of other DNS servers that authoritative for second-level domains
- 18. A DNS zone containing records that translate names to IP addresses, such as A, AAAA, and MX records. it's named after the domain whose resource records it contains
- 19. An A record used to resolve the name in a NS (Name Server) record to its IP address
- 20. A DNS server that holds a complete copy of a zone's resource records.
- 24. A type of DNS query to which a DNS server responds with the best information it has to satisfy the query. the DNS server doesn't query additional DNS servers in an attempt to resolve the query
- 28. A response to an iterative query in which the address of another name server is returned to the requester; a prioritized list of servers used to access files in a namespace
- 29. A DNS zone containing a read-only copy of only the zone's SOA (Start of Authority) and NS records
- 30. A type of DNS resource record that is used to resolve a domain name in an email address to the IP address of a mail server for that domain
