You administer your company network. The network consists of a single Active Directory domain named verigon.com. All five domain controllers run Windows Server 2003 and DNS Server, and they all host an Active Directory-integrated DNS zone for the verigon.com domain. You install DNS Server on a new Windows Server 2003 member server named ServerA. You configure ServerA to host a secondary zone for the verigon.com domain. On one of the domain controllers, you open the Properties dialog box for the verigon.com DNS zone. You must designate ServerA as an authoritative server for the verigon.com zone. Which tab should you select?
A. Start of Authority (SOA) B. Name Servers C. WINS D. Zone Transfers
Name servers-explanation: to indicate that servera hosts a zone for the verigon.com domain and to designate servera as an authoritative server for that domain, you should add a name server (ns) record to the zone by specifying the name and ip address of servera in the name servers list on the name servers tab.the name servers tab in this scenario, should contain one ns record for each authoritative dns server for the zone: one ns record for each of the five domain controllers, which host the active directory-integrated zone for the verigon.com domain, and one ns record for servera, which hosts a secondary zone for the verigon.com domain. on the start of authority (soa) tab, an soa record for a dns zone can be configured. if a dns zone is standard, then there is only one soa record, which contains the name or ip address of the only primary server for that zone. if a zone is active directory-integrated, then there can be multiple soa records, with one record for each primary server. the soa record on each primary server contains that servers name or ip address. in this scenario, servera hosts a secondary zone; therefore, its name or ip address should not be specified in the soa record on any of the primary servers for that zone. the wins tab is used to specify ip addresses of wins servers to configure dns to work with wins to resolve the names that are registered with wins, but are not registered with dns. you should enable the use wins forward lookup option to configure the dns zone to use wins forward lookups. the do not replicate this record option should be selected if you do not want to replicate a record. the ip addresses of the wins servers should be entered in the ip address text box. records obtained by the dns server from the wins server will be marked as authoritative and will be stored in the dns cache, not the zone. the ttl value of these records is decreased while the records are in cache. on the zone transfers tab, you can specify whether and how zone transfers to secondary dns servers occur in a dns zone. secondary zones are read-only; they do not accept dynamic updates from dns clients or manual changes from administrators. each secondary zone is updated by using zone transfers from a master server, which can be a primary or secondary server for the zone. zone transfers can be allowed to any dns server, to only the servers that are specified on the name servers tab, or to the servers that are explicitly listed on the zone transfers tab. if you select only to the following servers on this tab, then you should add the ip address of servera. however, specifying servera on the zone transfers tab does not designate servera as an authoritative server for the zone.
