CIT233 Win Server Ent Services - Terms Chapters 3 - 5

Delegation Signer (DS) A DNSSEC record that holds the name of a delegated zone and is used to verify delegated child zones. See also Domain Name System Security (DNSSEC).
DHCP failover A new feature in Windows Server 2012 that allows two DHCP servers to share the pool of addresses in a scope, giving both servers access to all addresses in the pool.
DHCP name protection A feature in DHCP that prevents name squatting by non-Windows computers by using a DHCP resource record called Dynamic Host Configuration Identifier (DHCID). See also name squatting.
DHCP Unique Identifier (DUID) A hexadecimal number, usually derived from the MAC address of the network interface used by DHCPv6 to identify clients for address leases and to create reservations.
DNS cache locking A DNS security feature that allows you to control whether data in the DNS cache can be overwritten.
DNS cache poisoning An attack on DNS servers in which false data is introduced into the DNS server cache, causing the server to return incorrect IP addresses.

Dynamic Host Configuration Protocol (DHCP) A component of the TCP/IP protocol suite used to assign an IP address to a host automatically from a defined pool of addresses.
GlobalNames zone (GNZ) A DNS feature that gives IT administrators a way to add single-label names to DNS, thereby allowing client computers to resolve these names without including a DNS suffix in the query.
hot standby mode A DHCP failover mode in which one server is assigned as the active server to provide DHCP services to clients, and the other server is placed in standby mode. See also DHCP failover.
iterative query A DNS query in which the server responds with the best information it currently has in its local database to satisfy the query.
key-signing key (KSK) A DNSSEC key that has a private and public key associated with it. The private key is used to sign all DNSKEY records, and the public key is used as a trust anchor for validating DNS responses. See also Domain Name System Security Extension (DNSSEC).

name squatting A DNS problem that occurs when a non-Windows computer registers its name with a DNS server, but the name has already been registered by a Windows computer.
netmask ordering A DNS feature that causes the DNS server to order the list of addresses so that the ones with a closer address match to the client making the query are returned at the top of the list.
Next Secure (NSEC) A DNSSEC record that is returned when the requested resource record does not exist. See also Domain Name System Security Extension (DNSSEC).
Next Secure 3 (NSEC3) An alternative to NSEC records. They can prevent zone-walking, which is a technique of repeating NSEC queries to get all the names in a zone. See also Next Secure (NSEC).
Next Secure 3 (NSEC3) Parameter DNSSEC records used to determine which NSEC3 records should be included in responses to queries for nonexistent records. See also Next Secure 3 (NSEC3).

Resource Record Signature (RRSIG) A key containing the signature for a single resource record, such as an A or MX record.
scope A pool of IP addresses and other IP configuration parameters that a DHCP server uses to lease addresses to DHCP clients.
split scope A fault-tolerant DHCP configuration in which two DHCP servers share the same scope information, allowing both servers to offer DHCP services to clients.
stateful autoconfiguration A method of IPv6 autoconfiguration in which the node uses an autoconfiguration protocol, such as DHCPv6, to obtain its IPv6 address and other configuration information.
stateless autoconfiguration A method of IPv6 autoconfiguration in which the node listens for router advertisement messages from a local router.
superscope A special type of scope consisting of one or more member scopes that allows a DHCP server to service multiple IPv4 subnets on a single physical network.

block-level storage Storage seen by the storage client as a local drive.
BranchCache A file-sharing technology that allows computers at a branch office to cache files retrieved from a central server across a WAN link.
classification property A file attribute containing a value that’s used to categorize the data in a file or an aspect of the file, such as its location or creation time.
content information A message transferred from a BranchCache server to a client that indicates to the client where the file can be retrieved from the cache in the branch office. See also BranchCache.
distributed cache mode A BranchCache mode of operation in which cached data is distributed among client computers in the branch office. See also BranchCache.
feature file store A network share containing the files required to install roles, role services, and features on Windows Server 2012/R2 servers.
Features on Demand A feature in Windows Server 2012/R2 that enables you to remove Unneeded installation files and free up the disk space they normally consume.
File Classification Infrastructure (FCI) A feature of File Server Resource Manager that allows classifying files by assigning new properties to them. The properties can then be used to create rules for searching or perform tasks on files meeting the criteria of the assigned properties.
file-level storage Storage that the client has access to only as files and folders.
global object access auditing policy A group policy setting that affects the auditing status of an entire file system or Registry on computers in the scope of the GPO where the policy is defined.
hosted cache mode A BranchCache mode of operation in which cached data is stored on one or more file servers in the branch office. See also BranchCache.
Internet Storage Name Service (iSNS) An IP-based protocol used to communicate between iSNS clients and servers for the purpose of allowing iSCSI devices to discover and monitor one another.
