In-Depth Information
12. You have Windows Server 2008 DNS servers, Windows Server 2003 DNS servers, and
Windows 2000 DNS servers. You just created a new zone, newzone.com, that you want
replicated by Active Directory to all DNS servers. Where should you store the zone?
a. ForestDNSZones partition
b. Newzone.com.dns
c. DomainDNSZones partition
d. Domain partition
13. The DNS server at your headquarters holds a standard primary zone for the abc.com
domain. A branch office connected by a slow WAN link holds a secondary zone for abc.com.
Updates to the zone aren't frequent. How can you decrease the amount of WAN traffic
caused by the secondary zone checking for zone updates?
a. In the SOA tab of the zone's Properties dialog box, increase the minimum (default) TTL.
b. In the Advanced tab of the DNS server's Properties dialog box, increase the expire
interval.
c. In the SOA tab of the zone's Properties dialog box, increase the refresh interval.
d. In the Zone Transfers tab of the SOA Properties dialog box, decrease the retry interval.
14. You have delegated a subdomain to a zone on another server. Several months later, you
hear that DNS clients can't resolve host records in the subdomain. You discover that the
IP address scheme was changed recently in the building where the server hosting the sub-
domain is located. What can you do to make sure DNS clients can resolve hostnames in
the subdomain?
a. Configure a forwarder pointing to the server hosting the subdomain.
b. Edit the NS record in the delegated zone on the parent DNS server.
c. Edit the NS record in the delegated zone on the DNS server hosting the subdomain.
d. Configure a root hint pointing to the server hosting the subdomain.
15. You want a DNS server to handle queries for a domain with a standard primary zone hosted
on another DNS server. You don't want your server to be authoritative for that zone. How
should you configure your server? (Choose all that apply.)
a. Configure a secondary zone on your DNS server.
b. Configure a stub zone on your DNS server.
c. Configure a forwarder on your DNS server.
d. Configure a delegation on your Web server.
16. You're in charge of a standard primary zone for a large network with frequent changes to
the DNS database. You want changes to the zone to be transmitted as quickly as possible to
all secondary servers. What should you configure and on what servers?
17. You have several hundred client computers using WINS to resolve names of some enterprise
servers. Many of the client computers are laptops used to connect to the network remotely.
You're trying to eliminate WINS from your network to reduce the number of protocols and
services you must support. What can you do, with the least administrative effort, that allows
you to stop using WINS yet still allows clients computers to use a single-label name for
accessing enterprise servers?
a.
Create a GlobalNames zone and add CNAME records for enterprise servers.
b.
Create a Hosts file containing servers' names and addresses and upload the Hosts file to
each client that needs it.
c.
Configure each client computer with the correct domain suffix.
d.
Create a stub zone and add CNAME records for each enterprise server.
