100
This is a balancing mechanism that distributes network loads among multiple servers by rotating resource records from a DNS server.
What is Round-Robin DNS?
100
This is the complete or partial transfer of DNS data from a zone on a DNS server to another DNS server.
What is a zone transfer?
100
Another name for a DNS Client.
What is a resolver?
100
Use this command line command to verify local DNS settings.
What is ipconfig /all?
100
Before you can create pointer records in DNS, you must have this.
What is a reverse lookup zone?
200
This value defines the default time a resource record remains in a DNS cache after a DNS query has retrieved a record.
What is TTL (time to live)?
200
This type DNS record specifies authoritative information about a DNS zone, including the primary name server, the e-mail of the domain administrator, the domain serial number, and the expiration and reload timers of the zone.
What is a SOA (start of authority) record?
200
These are the questions for which you need answers before installing and deploying DNS in your network.
What is - How busy are the servers? What kind of fault tolerance is needed? What kind of performance is required, and What kind of security is needed?
200
Two events that can trigger a zone transfer.
What is when a secondary zone is created, the zone refresh interval expires, the DNS Server service is started at the secondary server, and the master server notifies the secondary server that changes have been made to a zone? (This is more than two.)
200
Second level domains are owned by these.
What is people or organizations?
300
The generic name for a specific computer or other network device.
What is a host?
300
Use a DNS forwarder for this reason.
What is - By using a forwarder, you control name resolution queries and traffic, which can improve the efficiency of name resolution for the computers in your network?
300
This happens during an incremental zone transfer.
What is only resource records that have changed within a zone will be retrieved?
300
These allow you to break up larger domains into smaller, more manageable domains.
What are subdomains?
300
In DNS a cononical or cname is sometimes referred to as this.
What is an alias?
400
This is a time that a caching-only server is needed.
What is you use caching-only DNS servers when DNS is needed locally, but you do not want to create a separate domain or zone?
400
A good reason for knowing command line options for dnscmd.exe.
What is dnscmd.exe can be used in scripts to automate some DNS maintenance tasks?
400
Top level domains are made up of these generic types.
What is .com, .org, .edu, .gov, and .net? (To name a few.)
400
Name three types of zone transfers.
What is full, incremental, and DNS notify?
400
This type of DNS zone resolves host names to IP addresses.
What is a forward lookup zone?
500
This is a copy of a zone that contains only necessary resource records—Start of Authority (SOA), Name Server (NS), and Address/Host (A) record—in the master zone and acts as a pointer to the authoritative name server.
What is a stub zone?
500
If you are using Active Directory-Integrated zones, you are following this model.
What is a multi-master model?
500
Command line command used to view the zones on a DNS server named RWDC01.contoso.com
What is dnscmd RWDC01.contoso.com /enumzones?
500
This DNS server receives client requests, and as the DNS servers fulfill DNS queries, the server adds the information to its cache. It will not do name resolution requests on its own.
What is a caching-only server?
500
One primary advantage of using Active Directory to store DNS information is this.
What is fault, tolerance, security, and efficient replication? Any of these are acceptable.
