Q

Flashcard question: How does internet queries work?

A

Flashcard answer: When a client wants to access a website, it sends a query to the local DNS resolver, which is typically provided by the client’s ISP. The local resolver will first check its cache to see if it has a recent copy of the requested DNS record. If it does not, it will send a query to the root DNS server. The root server will respond with the address of the top-level domain (TLD) DNS server, such as .com or .org. The local resolver will then send a query to the TLD server, which will respond with the address of the authoritative DNS server for the domain in question. The local resolver will then send a query to the authoritative server, which will finally return the IP address for the requested website.

Q

Flashcard question: What is a domain?

A

Flashcard answer: A subset of the DNS namespace that is used to organize and identify resources on the Internet, a unique string of characters that identifies a domain, such as example.com and organized into a hierarchical structure, with the most specific domain at the top and the least specific at the bottom.

23

A

Flashcard answer: DNS zones are defined by the domain names they contain and manage the mapping of domain names to IP addresses and other information related to the domain names within that zone, while domain is a unique string of characters that identifies a domain such as example.com and is organized into a hierarchical structure.

25
Q

Flashcard question: What is a primary zone?

27
Q

Flashcard question: What is a forward zone?

A

Flashcard answer: A DNS zone that is used to resolve domain names to IP addresses, DNS records in a forward zone map a domain name, such as example.com, to an IP address, such as 192.0.2.1.

28
Q

Flashcard question: What is a reverse zone?

A

Flashcard answer: A DNS zone that is used to resolve IP addresses to domain names, DNS records in a reverse zone map an IP address, such as 192.0.2.1, to a domain name, such as example.com.

29
Q

Flashcard question: What is a resource record?

A

Flashcard answer: Individual entries in a DNS zone file that contain information about a specific domain or host, map domain names to IP addresses and other information such as the addresses of mail servers, text records and more.

30
Q

Flashcard question: What kind of information do resource records contain?

A

Flashcard answer: Resource records contain information such as domain name, IP address, addresses of mail servers, text records and other information relevant to its type.

31
Q

Flashcard question: What is the function of resource records?

A

Flashcard answer: The function of resource records is to provide information about a specific domain or host, including the IP address, to the DNS servers and clients, in order to help them to find the correct location of the requested resource.

32
Q

Flashcard question: What are the different types of resource records?

A

Flashcard answer: Common types of resource records include A (Address), MX (Mail Exchanger), NS (Name Server), PTR (Pointer), and CNAME (Canonical Name).

33
Q

Flashcard question: What are resource records in DNS?

A

Flashcard answer: Resource records (RRs) are individual entries in a DNS zone file that contain information about a specific domain or host, such as mapping domain names to IP addresses and other information.

34
Q

Flashcard question: What information do resource records contain?

A

Flashcard answer: Resource records contain information such as domain names, IP addresses, addresses of mail servers, text records and other information relevant to its type.

35
Q

Flashcard question: What is the purpose of resource records in DNS?

A

Flashcard answer: The purpose of resource records is to provide information about a specific domain or host, including the IP address, to the DNS servers and clients in order to help them find the correct location of the requested resource.

36
Q

Flashcard question: What are the different types of resource records?

A

Flashcard answer: Common types of resource records include A (Address), MX (Mail Exchanger), NS (Name Server), PTR (Pointer), and CNAME (Canonical Name).

37
Q

Flashcard question: What is the format of a resource record?

A

Flashcard answer: The format of a resource record includes a name, a time-to-live (TTL) value, a class, and type-specific data.

38
Q

Flashcard question: What are NetBIOS names?

A

Flashcard answer: NetBIOS names are a naming system used by Windows-based systems to identify and locate resources on a local area network (LAN), 15 characters or less, used to identify a specific computer or service on a LAN.

39
Q

Flashcard question: How are NetBIOS names used?

A

Flashcard answer: NetBIOS names are used in conjunction with the NetBIOS over TCP/IP (NBT) protocol, which allows Windows-based systems to communicate with each other on a LAN.

40
Q

Flashcard question: What is the purpose of NetBIOS names?

A

Flashcard answer: The purpose of NetBIOS names is to provide a human-readable and memorable way to identify resources on a local area network and make communication between computers in a LAN easier.

41
Q

Flashcard question: How are NetBIOS names different from hostnames?

A

Flashcard answer: Hostnames are human-readable names that are used to identify a device on a network, while NetBIOS names are a specific naming system used by Windows-based systems to identify and locate resources on a local area network (LAN).

42
Q

Flashcard question: What is LMHOSTS file?

A

Flashcard answer: LMHOSTS (Local Machine Hosts) is a plain-text file used by Windows-based systems to resolve NetBIOS names to IP addresses on a local area network (LAN).

43
Q

Flashcard question: What is the purpose of LMHOSTS file?

A

Flashcard answer: The purpose of LMHOSTS file is to resolve NetBIOS names when a DNS server is not available or when a specific IP address needs to be associated with a NetBIOS name.

44
Q

Flashcard question: Where is the LMHOSTS file typically located?

A

Flashcard answer: The LMHOSTS file is typically located in the \Windows\System32\Drivers\Etc directory.

45
Q

Flashcard question: What kind of information does LMHOSTS file contain?

A

Flashcard answer: LMHOSTS file contains a list of NetBIOS names and corresponding IP addresses.

46
Q

Flashcard question: When is it useful to use LMHOSTS file?

A

Flashcard answer: LMHOSTS file can be useful in situations where a DNS server is not available or when a specific IP address needs to be associated with a NetBIOS name.

47
Q

Flashcard question: What is WINS?

A

Flashcard answer: WINS (Windows Internet Name Service) is a Microsoft service that is used to resolve NetBIOS names to IP addresses on a Windows-based network.

48
Q

Flashcard question: What is the purpose of WINS?

A

Flashcard answer: The purpose of WINS is to provide name resolution services for client computers, allowing them to locate resources on the network using NetBIOS names.

49
Q

Flashcard question: How is WINS deployed and configured?

A

Flashcard answer: WINS servers can be deployed and configured on a LAN to provide name resolution services for client computers.

50
Q

Flashcard question: What is the process of client NetBIOS name-resolution?

A

Flashcard answer: When a client computer needs to resolve a NetBIOS name, it first checks its local cache for the name resolution. If the name is not found in the cache, the client will broadcast a request for the name on the local network. If a WINS server is available on the network, it will respond to the broadcast with the IP address associated with the requested NetBIOS name. If no WINS server is available, the client will use broadcast name resolution.

51
Q

Flashcard question: What is a GlobalNames zone in DNS?

A

Flashcard answer: A GlobalNames zone is a feature in DNS that allows for the creation of single-label names, such as “www” instead of “www.example.com”, to be resolved to their fully qualified domain name (FQDN) equivalents.

52
Q

A

Flashcard answer: A GlobalNames zone is created and configured on a DNS server.

53
Q

Flashcard question: What are the benefits of using a GlobalNames zone?

A

Flashcard answer: The benefits of using a GlobalNames zone include easier and more consistent name resolution across the network, as well as reducing the potential for naming conflicts.
