Moog Controls Interview Questions and Answers

DNS is used to translate domain names to IP addresses. If internet is not working, check DNS settings, troubleshoot network connection, and contact ISP.

• Check DNS settings to ensure they are configured correctly

• Troubleshoot network connection to identify any issues

• Contact Internet Service Provider (ISP) to check for any outages or problems

• Try using alternative DNS servers like Google DNS (8.8.8.8, 8.8.4.4)

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

• The OSI model stands for Open Systems Interconnection model

• It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application

• Each layer has specific functions and communicates with the adjacent layers

• The Application layer is the top layer and is responsible for providing network services to user applicat...read more

Static IP is manually assigned and does not change, while dynamic IP is automatically assigned and can change.

• Static IP is manually configured by a network administrator.

• Dynamic IP is assigned by a DHCP server automatically.

• Static IP is useful for servers, while dynamic IP is common for home networks.

• Static IP provides consistency for services like web hosting, while dynamic IP is more flexible for devices that move between networks.

DHCP is a network protocol that automatically assigns IP addresses to devices on a network.

• DHCP stands for Dynamic Host Configuration Protocol

• It allows devices to obtain IP addresses and other network configuration information automatically

• DHCP servers are responsible for assigning and managing IP addresses within a network

• DHCP clients request IP addresses from DHCP servers when they connect to a network

Private IP addresses are reserved for use within a private network and are not routable on the public internet.

• Private IP addresses are used within a local network to uniquely identify devices.

• They are not accessible from the internet.

• Examples of private IP address ranges include 192.168.0.0 - 192.168.255.255 and 10.0.0.0 - 10.255.255.255.

DNS (Domain Name System) translates domain names to IP addresses to enable communication between devices on a network.

• DNS resolves domain names to IP addresses

• DNS uses a hierarchical system of servers to store and distribute domain name information

• DNS records include A records (IPv4 addresses), AAAA records (IPv6 addresses), MX records (mail servers), and more

IPv4 and IPv6 are two different versions of the Internet Protocol used to identify and locate devices on a network.

• IPv4 is the fourth version of the Internet Protocol and uses a 32-bit address scheme.

• IPv6 is the sixth version of the Internet Protocol and uses a 128-bit address scheme.

• IPv4 addresses are written in decimal format, separated by periods (e.g. 192.168.1.1).

• IPv6 addresses are written in hexadecimal format, separated by colons (e.g. 2001:0db8:85a3:0000:0000:8a2e:037...read more

DORA process stands for Discover, Offer, Request, and Acknowledge in DHCP communication.

• Discover: Client broadcasts a DHCPDISCOVER message to find available DHCP servers.

• Offer: DHCP server responds with a DHCPOFFER message containing IP address lease information.

• Request: Client sends a DHCPREQUEST message to request the offered IP address.

• Acknowledge: DHCP server sends a DHCPACK message to confirm the IP address lease to the client.
