In this article, we will dive into the concept of DNS servers and explore their functions through a set of multiple-choice questions (MCQs). Let’s get started!
What Is a DNS Server?
A DNS server stands for Domain Name System server. It is an essential component of the internet infrastructure that translates domain names into IP addresses. When you enter a URL into your web browser, the DNS server is responsible for finding the corresponding IP address of that domain.
Functions of a DNS Server – MCQs
What does DNS stand for?
- Domain Name System
- Digital Network Service
- Data Naming Server
- Distributed Network System
Which of the following is NOT a function of a DNS server?
- Translating domain names to IP addresses
- Caching recently accessed IP addresses for faster future access
- Maintaining website content and databases
- Facilitating email delivery by resolving MX records
What is the purpose of caching in a DNS server?
- To improve website performance by storing frequently accessed IP addresses locally
- To encrypt sensitive data during transmission between client and server
- To prevent unauthorized access to the DNS server’s configuration settings
- To filter malicious websites and protect users from online threats
Which record type is used to map a domain name to an IP address?
- A (Address) record
- CNAME (Canonical Name) record
- MX (Mail Exchange) record
- NS (Name Server) record
What happens if a DNS server fails to resolve a domain name?
- The web browser will display an error message indicating the DNS resolution failure
- The DNS server will automatically redirect the request to another server for resolution
- The web browser will display cached information from previous requests instead of the current data
- The DNS server will generate a temporary domain name and provide it as an alternative option
Congratulations on completing the MCQs! By now, you should have a better understanding of the functions of a DNS server. Remember that DNS plays a crucial role in translating domain names into IP addresses, caching frequently accessed addresses for faster resolution, and facilitating various internet services.
