The SRV record is a resource record in DNS that is used to identify or point to a COMPUTER that host specific services i.e ACTIVE directory.

DNS SERVERS running Windows Server support aging and scavenging features. These features are PROVIDED as a mechanism to perform cleanup and REMOVAL of stale resource RECORDS from the server and zone. This FEATURE removes the dynamically created records when they are stamped as stale.
By default, the aging and scavenging mechanism for the DNS Server service is disabled.
Scavenging and aging must be enabled both at the DNS server and on the zone

Caching-only servers are those DNS servers that only perform name resolution queries, CACHE the answers, and RETURN the RESULTS to the client. Once the query is stored in cache, next time the query in resolved LOCALLY from cached instead of going to the actual site.

A stub ZONE is a read only copy of a zone that contains only those resource records which are necessary to identify the authoritative DNS servers for that particular zone. A stub zone is practically used to resolve names between separate DNS namespaces. This type of zone is generally created when a corporate merger or acquire and DNS servers for TWO separate DNS namespaces resolve names for CLIENTS in both namespaces.
A stub zone contains:

• The start of AUTHORITY (SOA) resource record, name server (NS) resource records, and the glue A resource records for the delegated zone.
• The IP ADDRESS of one or more master servers that can be used to update the stub zone.

This is the READ only COPY of a zone file in the DNS namespace. This is secondary source for information about the zone and it get the updated information from the master copy of primary zone. The NETWORK access must be available to connect with primary SERVER. As secondary zone is merely a copy of a primary zone that is hosted on another server, it cannot be stored in AD DS.

This is the READ and writable copy of a zone file in the DNS NAMESPACE. This is primary source for information about the zone and it STORES the master copy of zone data in a local file or in AD DS. Dy default the primary zone file is NAMED as zone_name.dns in %windir%System32DNS folder on the server.

Forward LOOKUP: When a name query is SEND to the DNS server against to IP address, it is generally said a forward lookup.
Reverse Lookup: DNS also PROVIDES a reverse lookup process, enabling clients to use a KNOWN IP address during a name query and look up a computer name based on its address.

A (Address) Maps a host name to an IP address. When a computer has MULTIPLE adapter cards and IP addresses, it should have multiple address records.
CNAME (Canonical Name) Sets an ALIAS for a host name. For example, using this record, zeta.tvpress.com can have an alias as www.tvpress.com.
MX (MAIL Exchange) Specifies a mail exchange server for the domain, which allows mail to be delivered to the correct mail servers in the domain.
NS (Name Server) Specifies a name server for the domain, which allows DNS lookups within various ZONES. Each primary and secondary name server should be declared through this record.
PTR (Pointer) Creates a pointer that maps an IP address to a host name for reverse lookups.
SOA (Start of Authority) Declares the host that is the most authoritative for the zone and, as such, is the best SOURCE of DNS information for the zone. Each zone file must have an SOA record (which is created automatically when you add a zone).

Dynamic DNS or DDNS is a method of updating, in real time, a Domain Name System to point to a changing IP ADDRESS on the Internet. This is used to provide a PERSISTENT domain name for a resource that may CHANGE location on the network.
