Movate Technical Support Engineer Interview Questions and Answers

IPSec is a protocol suite used for secure communication over IP networks.

• IPSec operates in two modes: Transport mode and Tunnel mode.

• In Transport mode, only the payload of the IP packet is encrypted and/or authenticated.

• In Tunnel mode, the entire IP packet is encrypted and/or authenticated.

• IPSec uses security protocols like Authentication Header (AH) and Encapsulating Security Payload (ESP) to provide data integrity, a...read more

DHCP stands for Dynamic Host Configuration Protocol. It is a network management protocol used to assign IP addresses to devices on a network.

• DHCP automatically assigns IP addresses to devices on a network

• There are two types of DHCP: DHCP server and DHCP client

• DHCP server assigns IP addresses to devices, while DHCP client requests and receives IP addresses

Accessing google.com involves DNS resolution, TCP handshake, HTTP request, and response at the packet level.

• 1. DNS resolution to translate domain name to IP address

• 2. TCP handshake to establish connection

• 3. HTTP request sent to the server

• 4. Server processes the request and sends back HTTP response

• 5. Data packets are exchanged between client and server

• Test different solutions and document the results to track progress.

• Keep detailed notes of the troubleshooting process for future reference.

• Consider reaching out to the vendor or manufacturer fo...read more

An IP address can be found by checking network settings on a device or using online tools.

• Check network settings on device (e.g. Windows: Control Panel > Network and Sharing Center > Change adapter settings)

• Use online tools like ipchicken.com or whatismyip.com

• Command prompt: type 'ipconfig' (Windows) or 'ifconfig' (Mac/Linux)

Understanding of OSI Layers, MAC vs IP, ARP types, SSL handshake, and TCP handshake.

• OSI Layers: 7 layers that define networking functions

• MAC vs IP: MAC address is hardware address, IP address is logical address

• ARP types: ARP, RARP, Inverse ARP

• SSL handshake: Process of establishing secure connection

• TCP handshake: 3-way process to establish connection

DHCP stands for Dynamic Host Configuration Protocol, which is a network management protocol used to assign IP addresses automatically to devices on a network.

• DHCP eliminates the need for manual IP address configuration on each device

• It dynamically assigns IP addresses to devices when they connect to the network

• DHCP servers lease IP addresses to devices for a specific period of time

• DHCP also provides other network confi...read more

DNS stands for Domain Name System, which translates domain names to IP addresses.

• DNS is like a phone book for the internet, translating human-readable domain names (like google.com) to IP addresses (like 172.217.3.206).

• DNS servers store DNS records, which contain information about domain names and their corresponding IP addresses.

• DNS operates through a hierarchical system, with different levels of DNS servers responsib...read more

OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.

• OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, Application

• Each layer has specific functions and communicates with adjacent layers

• Example: HTTP operates at the Application layer, while TCP operates at the Trans...read more

ARP stands for Address Resolution Protocol, used to map IP addresses to MAC addresses on a local network.

• ARP is used to find the MAC address of a device based on its IP address.

• It operates at the data link layer of the OSI model.

• ARP requests are broadcasted to all devices on the local network.

• Once the device with the corresponding IP address responds, its MAC address is stored in the ARP table.

• ARP cache poisoning is a ...read more
