Practice Questions
Question 1
Reorder the following events in setting up an AD network into their proper order:
The correct answer is:
Question 2
Which of the following is not a reason to use AD integrated zones rather than standard zones?
Fault tolerance.
Security.
Simplicity of management.
The database is stored in easy-to-edit text files.
Answer d is correct. AD integrated zones store zone information within the AD database. Answer d refers to standard zones, which store the DNS database in text files that carry a .dns extension. Answers a, b, and c are incorrect because fault tolerance, security, and simplicity of management are all legitimate reasons to use AD integrated zones.
Question 3
Which of the following DC resource record types would you look for if trying to troubleshoot workstations not being able to log on to a domain? [Check all correct answers]
A
CNAME
SRV
MX
Answers a and c are correct. You would check for the proper registration of Address and Service records. Answer b is incorrect because CNAME records are aliases. Answer d is incorrect because MX records are for mail servers.
Question 4
The following are types of name servers:
Match the following features with the name server type they are most associated with:
The correct answer is:
Active Directory integrated
Standard primary and secondary
Question 5
Under which of the following circumstances could you use Windows 98 clients in a dynamic update situation? [Choose the best answer]
When the Only Secure Updates option is enabled on the DNS server.
When the Allow Dynamic Updates? option is set to Yes on the DNS server.
When the Enable Updates For DNS Clients That Do Not Support Dynamic Updates option is enabled on the DHCP server.
Legacy clients cannot be supported by dynamic update.
Answer c is correct. By default, dynamic update is not supported by legacy clients; however, DHCP can be configured to act as a proxy on their behalf. Answers a and b are incorrect because simply enabling dynamic updating or secure updates will not allow Windows 98 clients to register with DNS. Answer d is incorrect because they can be supported.
Question 6
Which of the following types of name servers store copies of a zone database? [Check all correct answers]
AD integrated
Caching
Primary
Secondary
Answers a, c, and d are correct. AD integrated, primary, and secondary name servers all store copies of a zone database. Answer b is incorrect because caching is the only type in the list that does not store an editable copy of a zone database.
Question 7
Which of the following name-resolution methods use manually updated text files to record name mappings? [Check all correct answers]
DNS
HOSTS
WINS
LMHOSTS
Answers b and d are correct. HOSTS was a name-toIP address mapping system used prior to the advent of DNS on the Internet. LMHOSTS resolved NetBIOS names on Windows networks before WINS and later DNS. Answers a and c are incorrect because DNS and WINS are both dynamically updated databases, whereas HOSTS and LMHOSTS use text files to store their mappings.
Question 8
Which of the following elements is required to successfully install and configure DNS? [Choose the best answer]
DHCP
Static IP address
Active Directory
Windows 2000 clients
Answer b is correct. To install and configure a working DNS server, the server running DNS must have a static IP address. Answer a is incorrect because DHCP is not required to use DNS, although it is necessary if you want to enable dynamic update. Answer c is incorrect because Active Directory is not required. Answer d is incorrect because DNS works with legacy clients as well as Windows 2000 clients.
Question 9
When monitoring a DNS server, which type of test sends a query to other name servers for resolution? [Choose the best answer]
Simple query
Recursive query
Forward lookup query
Iterative query
Answer b is correct. A recursive query sends a resolution query to other servers when monitoring the server. Answer a is incorrect because a simple query resolves the name against only the server being tested. Answers c and d are incorrect because these are not valid choices for DNS monitoring.
Question 10
In a standard primary zone, what name server(s) can an administrator update the zone database on? [Choose the best answer]
Secondary
Active Directory integrated
Primary
Any server
Answer c is correct. In a standard primary zone, only the primary server can be updated directly. Answer a is incorrect because secondary servers receive updates through zone transfer. Answer b is incorrect because Active Directory integrated servers don't exist in a standard primary zone. Answer d is incorrect because only the primary server can be updated in this way.
