Your network contains two Active Directory forests named contoso.com and dev.contoso.com. The contoso.com forest contains a domain controller named DC1. The dev.contoso.com forest contains a domain controller named DC2. Each domain contains an organizational unit (OU) named OU1.
Dev.contoso.com has a Group Policy object (GPO) named GPO1. GPO1 contains 200 settings, including several settings that have network paths. GPO1 is linked to OU1.
You need to copy GPO1 from dev.contoso.com to contoso.com.
What should you do first on DC2?

• A.Run the Save-NetGpocmdlet.
• B.From the Group Policy Management console, right-click GPO1 and select Copy.
• C.Run the mtedit.exe command and specify the /Domaintcontoso.com /DC: DC 1 parameter.
• D.Run the Backup-Gpocmdlet.

You have a DNS server named DN51 that runs Windows Server 2012 R2.
On DNS1, you create a standard primary DNS zone named adatum.com.
You need to change the frequency that secondary name servers will replicate the zone from DNS1.
Which type of DNS record should you modify?

• A.Host information (HINFO)
• B.Service location (SRV)
• C.Start of authority (SOA)
• D.Name server (NS)

HOTSPOT
Your network contains a DNS server named Server1 that runs Windows Server 2012 R2. Server1 has a zone named contoso.com. The network contains a server named Server2 that runs Windows Server
2008 R2. Server1 and Server2 are members of an Active Directory domain named contoso.com.
You change the IP address of Server2.
Several hours later, some users report that they cannot connect to Server2.
On the affected users' client computers, you flush the DNS client resolver cache, and the users successfully connect to Server2.
You need to reduce the amount of time that the client computers cache DNS records from contoso.com.
Which value should you modify in the Start of Authority (SOA) record? To answer, select the appropriate setting in the answer area.

정답:

The Default TTL, is just that a default for newly created records. Once the records are created their TTL is independent of the Default TTL on the SO
A. Microsoft DNS implementation copies the Default TTL setting to all newly created records their by giving them all independent TTL settings.
SOA Minimum Field: The SOA minimum field has been overloaded in the past to have three different meanings, the minimum TTL value of all RRs in a zone, the default TTL of RRs which did not contain a TTL value and the TTL of negative responses.
Despite being the original defined meaning, the first of these, the minimum TTL value of all RRs in a zone, has never in practice been used and is hereby deprecated. The second, the default TTL of RRs which contain no explicit TTL in the master zone file, is relevant only at the primary server. After a zone transfer all RRs have explicit TTLs and it is impossible to determine whether the TTL for a record was explicitly set or derived from the default after a zone transfer. Where a server does not require RRs to include the TTL value explicitly, it should provide a mechanism, not being the value of the MINIMUM field of the SOA record, from which the missing TTL values are obtained. How this is done is implementation dependent.
TTLs also occur in the Domain Name System (DNS), where they are set by an authoritative name server for a particular resource record. When a caching (recursive) nameserver queries the authoritative nameserver for a resource record, it will cache that record for the time (in seconds) specified by the TTL. If a stub resolver queries the caching nameserver for the same record before the TTL has expired, the caching server will simply reply with the already cached resource record rather than retrieve it from the authoritative nameserver again.
Shorter TTLs can cause heavier loads on an authoritative nameserver, but can be useful when changing the address of critical services like Web servers or MX records, and therefore are often lowered by the DNS administrator prior to a service being moved, in order to minimize disruptions.
