Across
- 1. 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.
- 4. 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
- 7. A distributed hierarchical database composed mainly of a computer name and IP address pair
- 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
- 13. A DNS zone containing a read/write master master copy of all resource records for the zone; this zone is authoritative for the zone
- 15. The full domain name for a host that specifically identifies in within the hierarchy of the Domain Name System (DNS)
- 16. A DNS server to which other DNS servers send requests that can't resolve themselves.
- 17. A resource record in a DNS zone taht consists of a hostname and an IPv4 address
- 19. A computer making a DNS query
- 20. An audit event that tracks changes to a DNS server, such as when zone or resource changes are made, and is enabled by default
- 22. 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
- 23. A DNS zone containing a read-only copy of only the zone's SOA (Start of Authority) and NS records
- 24. 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
- 25. 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
- 27. An A record used to resolve the name in a NS (Name Server) record to its IP address
- 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
- 30. 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)
Down
- 2. A DNS server that holds a complete copy of a zone's resource records.
- 3. 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
- 5. A DNS server that maintains addresses of other DNS servers taht are authoritative for 2nd-level domains
- 6. 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
- 8. 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
- 10. A resource record in a DNS zone that consists of a hostname and an IPv6 address
- 11. Caching-only DNS server
- 12. A DNS name-registering process whereby computers in the domain can register or update their own DNS records
- 14. A DNS server taht keeps a database of addresses of other DNS servers managing top-level domain names
- 18. 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
- 21. 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
- 26. A type of DNS resource record that is used to resolve a known IP address to a hostname
- 29. A grouping of DNS information that represents one or more domains and possibly subdomains
