Advantages Of Dns In Windows Server 2012

Front 1

Background Zone Loading

Back 1

As the DNS restarts, the Active Directory zone data populates the database in the background. This allows the DNS server to service client requests for data from other zones almost immediately after a restart.
__________________ accomplishes this task by loading the DNS zone using separate threads. This allows a DNS server to service requests while still loading the rest of the zone. If a client sends a request to the DNS server for a computer that has not yet loaded into memory, the DNS server retrieves the data from Active Directory and updates the record.

Front 2

IPv4 and IPv6

Back 2

Microsoft Windows Server 2012 DNS has built-in support to accommodate both _____ and ______ address records

Front 3

DNS socket pools

Back 3

______________ allow source port randomization to protect against DNS cache-poisoning attacks.
when the DNS service starts, the DNS server will randomly pick a source port from a pool of available sockets. This is an advantage because instead of DNS using a well-known source port when issuing queries, the DNS server uses a random port selected from the ___________. This helps guard against attacks because a hacker must correctly access the source port of the DNS query. __________ are automatically enabled in DNS with the default settings.

Front 4

Domain Name System Security Extensions (DNSSEC),

Back 4

Windows Server 2012 can use a suite of extensions that will help add security to DNS, and that suite is called _______________ , which was introduced in Windows Server 2008 R2. The ______________ protocol allows your DNS servers to be secure by validating DNS responses. _______________ secures your DNS resource records by accompanying the records with a digital signature.

Front 5

Trust Anchors

Back 5

___________ are preconfigured public keys that are linked to a DNS zone. For a DNS server to perform validation, one or more ___________ must be configured. If you are running an Active Directory Integrated zone, ___________ can be stored in the Active Directory Domain Services directory partition of the forest. If you decide to store the ___________ in the directory partition, then all DNS servers that reside on a domain controller get a copy of this trust anchor. On DNS servers that reside on stand-alone servers, ___________ are stored in a file called ___________.dns.

Front 6

viewing trust anchors

Back 6

What is this command used for?
get-dnsservertrustanchor FQDN

Front 7

DNS devolution

Back 7

Using ____________, if a client computer is a member of a child namespace, the client computer will be able to access resources in the parent namespace without the need to explicitly provide the fully qualified domain name (FQDN) of the resource.

Front 8

weight

Back 8

_________ing DNS records will allow an administrator to place a value on DNS SRV records. Clients will then randomly choose SRV records proportional to the _________ value assigned.

Front 9

netmask ordering

Back 9

When an administrator configures ___________, the DNS server will detect the subnet of the querying client. The DNS server will then return a host address available for the same subnet.

Front 10

DnsUpdateProxy

Back 10

A DHCP server can be configured to register host (A) and pointer (PTR) resource records dynamically on behalf of DHCP clients. Because of this, the DNS server can end up with stale resources. To help solve this issue, an administrator can use the built-in security group called ____________.
