Question 1

Every AD domain in Windows Server 2008 has a naming convention based on a DNS domain name.

Accepted Answer

Windows Server 2008 uses a DNS domain name as the basis for the naming convention for AD domains. This helps to ensure that the domain name used for AD is unique and can be resolved within the DNS namespace.

Question 2

____ instructs a DNS server to forward nonauthoritative queries for a specific nonhosted domain, such as widgetsbiz.net, to a specific DNS server or servers.

Accepted Answer

Conditional forwarding is a feature of the DNS server that lets you specify a DNS domain for which the server is authoritative, forward queries to a specified DNS server based on specified criteria, and then return the results to the client. This is useful when you want to forward queries for a specific nonhosted domain to a specific DNS server or servers.

Question 3

By default, FQDN is configured to provide dynamic updates to clients that support this feature.

Accepted Answer

False

Question 4

At the ____ level, you can make configuration changes that are server specific. You can also perform maintenance tasks for a specific server.

Accepted Answer

At the DNS server level, you can make configuration changes and perform maintenance tasks for a specific server. DNS zone is a specific portion of the DNS namespace, DNS client refers to devices that query DNS servers for domain name resolution, DNS record is an entry in a DNS database that maps a domain name to an IP address or other information.

Question 5

A DNS server must support the SRV record type and dynamic update protocol, or Request for Comment (RFC)2136, to support an AD environment properly.

Accepted Answer

A DNS server that supports the SRV record type and dynamic update protocol is necessary for proper functioning of an Active Directory environment. This is specified in Request for Comment (RFC)2136.

Question 6

____ allows an administrator to configure load balancing of servers based on DNS name resolution information.

Accepted Answer

Round-robin DNS allows an administrator to configure load balancing of servers by alternating the IP addresses returned to clients in a round-robin fashion. This can be an effective and simple solution for load balancing. Delegation is used for delegating control of a subdomain to a different nameserver. Zone transfer is used for replicating DNS information between primary and secondary DNS servers. Forwarding is used for sending DNS requests to another DNS server for resolution. None of these options are directly related to load balancing based on DNS name resolution.

Question 7

Dynamic updates are configured at the DNS record level.

Accepted Answer

The answer of Dynamic updates are configured at the DNS...

Question 8

The ____ is the length of time records wait before they can refresh their time stamp.

Accepted Answer

The no-refresh interval is the length of time that records in a DNS zone can't refresh their time stamp. This period is set to minimize performance issues caused by unnecessary record updates. The no-refresh interval is typically set to 7 days by default.

Question 9

The ____ log file is set to a default size of 16,384 KB, though you can increase the size in increments of 64 KB.

Accepted Answer

The DNS Events log file is set to a default size of 16,384 KB and can be increased in increments of 64 KB. The other options (Global, root, domain) do not specify a particular log file and do not have a default size of 16,384 KB.

Question 10

The ____ is the length of time after a record can refresh that it is determined to be stale and scavenging can begin

Accepted Answer

The refresh interval is the length of time after a record can refresh that it is determined to be stale and scavenging can begin. The client interval refers to the time between a client's attempts to refresh its DNS cache. The DNS zone and DNS domain are not directly related to determining stale records for scavenging purposes.

Question 11

____ are designed to limit the replication traffic across wide area network (WAN)links, as this traffic can affect performance for clients and users.

Accepted Answer

AD DS sites are designed to limit the replication traffic across WAN links by dividing the domain into different sites based on physical or logical boundaries. This ensures that only necessary replication traffic is sent across WAN links, reducing the impact on performance for clients and users.

Question 12

Part of the netlogon service used by every client logging onto an Active Directory domain, the ____ runs at logon to provide the client with the location of a DC that can authenticate its requests.

Accepted Answer

The domain controller locator is a part of the netlogon service that runs during client logon to provide the client with the location of a domain controller that can authenticate its requests. This allows the client to access the resources it needs on the domain. Round-robin DNS is a load balancing technique used to distribute traffic among multiple servers, but it is not directly related to the netlogon service. The netlogon service itself is a service that runs on domain controllers and manages secure channel connections and logon requests. The root domain is the top level of a domain hierarchy and is not directly related to the netlogon service.

Question 13

____ is Microsoft's implementation of a directory services infrastructure.

Accepted Answer

AD DS (Active Directory Domain Services) is Microsoft's implementation of a directory services infrastructure, which is used to store and manage information about network resources, such as computers, users, printers, and applications, and to authenticate and authorize access to those resources within a domain environment. NetBIOS (Answer A) is an older networking protocol that is no longer widely used. BOOTP (Answer B) is a protocol used for booting diskless workstations in a networked environment. Kerberos (Answer C) is a network authentication protocol used to provide secure communication over a network by verifying the identity of clients and services. While Kerberos is integrated with AD DS, it is not synonymous with it.

Question 14

A(n)____ is used by AD DS for storing all of the AD objects and information about your network environment.

Accepted Answer

Domain controllers (DC) are the servers used by Active Directory Domain Services (AD DS) to store all AD objects and information about the network environment. Option A, OEM, refers to original equipment manufacturer and is not directly related to AD DS or network environment. Option C, domain, is a logical grouping of network resources and is closely related to AD DS, but it does not directly store AD objects and information. Option D, KDC, refers to Key Distribution Center, which is a component of the Kerberos authentication protocol, and is not directly related to AD DS storage.

Question 15

In ____, the DNS database is stored in AD, and DNS replication occurs through the normal AD replication process.

Accepted Answer

Active Directory-integrated DNS stores the DNS database in AD, and DNS replication is handled through the normal AD replication process. NetBIOS is a legacy protocol used for computer naming and communication. Kerberos is a network authentication protocol. DCDiag is a diagnostic tool used to check the health of domain controllers.

Question 16

The term ____ can refer to the common practice of assigning an FQDN to a computer or device whose IP address changes from time to time.

Accepted Answer

The term "Dynamic DNS" specifically refers to the practice of assigning a fully qualified domain name (FQDN) to a computer or device with a changing IP address. BIND is a domain name system (DNS) server software, a label is a component of the FQDN, and a stub zone is a type of DNS zone used for delegation. None of these terms refer specifically to the practice of Dynamic DNS.

Question 17

AD DS uses a database structure to maintain its objects.

Accepted Answer

This is true. AD DS uses a database structure to store and organize its objects, which include user accounts, computer accounts, and organizational units (OUs). This allows for efficient querying and management of the directory service.

Question 18

The ____ contains a subset of the event logs relating specifically to DNS called DNS Events.

Accepted Answer

The Global Logs folder contains a subset of the event logs relating specifically to DNS called DNS Events. The other options are not related to the DNS event logs in this context.

Question 19

____ is an excellent command-line tool for performing configuration and maintenance tasks on a DNS server.

Accepted Answer

DNScmd is specifically designed to perform configuration and maintenance tasks on a DNS server. It allows administrators to manage DNS servers and their associated zones and resource records through the command line interface.

Question 20

____ instructs a DNS server to forward all queries for DNS domains not hosted on a server to another server or servers

Accepted Answer

Standard forwarding is the instruction given to a DNS server to forward all queries for DNS domains not hosted on a server to another server or servers. This is particularly useful when a DNS server is unable to resolve a query, and it needs to request the information from another DNS server that has the information.
