What is the most common record type in DNS Mcq
The most common DNS record types are:
- Address Mapping record (A Record)—also known as a DNS host record, stores a hostname and its corresponding IPv4 address.
- IP Version 6 Address record (AAAA Record)—stores a hostname and its corresponding IPv6 address.
Which of these is a full form of DNS Mcq
DNS stands for domain name system .
How many types of DNS zones are there
There are two types of zone files: A DNS Primary File which authoritatively describes a zone. A DNS Cache File which lists the contents of a DNS cache—this is only a copy of the authoritative DNS zone.
What is DNS in cyber security Mcq
Explanation: DNS is a naming system given to different computers that adapt to human-readable domain names.
What is domain Mcq answer
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.
What is the importance of using DNS Mcq
Explanation: Root name servers are actually very important and critical as they are the first step in translating human readable hostnames into IP addresses for carrying out communication.
What is DNS zone example
DNS zones are not necessarily physically separated from one another, zones are strictly used for delegating control. For example, imagine a hypothetical zone for the cloudflare.com domain and three of its subdomains: support.cloudflare.com, community.cloudflare.com, and blog.cloudflare.com.
Which is the type of DNS scopes Mcq
The correct answer is "option 3". CONCEPT: DNS, which stands for Domain Name System, maps domain name into Internet Protocol (IP) address. Hence, the DNS maps the IP addresses to a hierarchy of domain names.
What is the use of PTR pointer record in DNS Mcq
A DNS pointer record (PTR for short) provides the domain name associated with an IP address. A DNS PTR record is exactly the opposite of the 'A' record, which provides the IP address associated with a domain name. DNS PTR records are used in reverse DNS lookups.
What is an alias record used for
An ALIAS record is a type of DNS record that points your domain name to a hostname instead of an IP address.
What type of protocol is HTTP Mcq
Explanation: HTTP is an Application layer protocol used to define how messages are formatted and transmitted through the World Wide Web.
What DNS database contains
DNS Database is the collection of database files, or zone files, and associated files that contain resource records for a domain. These files are stored on a name server. DNS database files are typically flat-file database files in the form of simple ASCII files.
What is wild card domain
A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a * as the leftmost label (part) of a domain name, e.g. *. example.com .
What is the function of the DNS
DNS servers convert URLs and domain names into IP addresses that computers can understand and use. They translate what a user types into a browser into something the machine can use to find a webpage. This process of translation and lookup is called DNS resolution.
What is the basic function of the nslookup program Mcq
The correct answer is A. The nslookup programs generates name server queries, and can be used to debug DNS.
What does a DNS client called
A DNS client is also called a resolver. When a client needs to resolve a remote host's name into its IP address, it sends a request to the DNS server, which returns the IP address of the remote host.
Which DNS resource record is used to reverse map IP addresses
What is DNS Resource Record
DNS Resource Record Type | Explanation |
---|---|
PTR Record | Pointer, used for reverse lookup (IP Address to Domain Name resolution) |
SRV Record | SRV record, used to map available services. Mainly used by Active Directory in Microsoft Windows Servers |
Is DNS decentralized system
The Domain Name System (DNS) is the hierarchical and decentralized naming system used to identify computers reachable through the Internet or other Internet Protocol (IP) networks. The resource records contained in the DNS associate domain names with other forms of information.
