Damodar Ropeways Infra Interview Questions and Answers

There are multiple ways to transfer data in CCNA, including wired and wireless methods.

• Data transfer methods in CCNA include Ethernet, Wi-Fi, Bluetooth, and cellular networks.

• Ethernet is a common wired method used for data transfer in CCNA.

• Wi-Fi allows for wireless data transfer over a local network.

• Bluetooth is used for short-range wireless data transfer between devices.

• Cellular networks enable data transfer over mobile networks.

IP stands for Internet Protocol, which is a logical address used to identify devices on a network.

• IP is a unique identifier assigned to each device connected to a network.

• It allows devices to communicate with each other by routing data packets.

• There are two versions of IP - IPv4 and IPv6.

• IPv4 addresses are 32 bits long and written in decimal format (e.g. 192.168.1.1).

• IPv6 addresses are 128 bits long and written in hexadecimal format (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:73...read more

VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol used to manage VLAN configurations across a network. VLANs are virtual LANs that separate broadcast domains.

• VTP is used to synchronize VLAN information across switches in a network

• It helps in reducing the administrative overhead of manually configuring VLANs on each switch

• VLANs are used to logically segment a network into separate broadcast domains

• VLANs improve network performance and security by isolating traffic

A network is a collection of computers, servers, mainframes, network devices, and other devices connected to one another for sharing data and resources.

• Networks can be wired or wireless

• Networks can be local (LAN), wide area (WAN), or global (Internet)

• Networks use protocols like TCP/IP for communication

Protocol is a set of rules that govern the communication between devices in a network.

• Protocol defines the format, timing, sequencing, and error checking of data transmission.

• Examples of protocols include TCP/IP, HTTP, FTP, and SMTP.

• Protocols ensure that devices can communicate effectively and understand each other's data.

Three-way handshake is a process used in TCP/IP networking to establish a connection between two devices.

• The client sends a SYN (synchronize) packet to the server.

• The server responds with a SYN-ACK (synchronize-acknowledge) packet.

• The client sends an ACK (acknowledge) packet to the server, and the connection is established.

• This process ensures that both devices are ready to communicate and establishes the parameters of the connection.

Basic requirements of CCNA include knowledge of networking fundamentals, routing and switching, and hands-on experience with Cisco devices.

• Understanding of networking fundamentals such as TCP/IP, subnetting, and OSI model

• Knowledge of routing and switching concepts including VLANs, STP, and routing protocols like OSPF and EIGRP

• Hands-on experience with Cisco routers and switches

• Ability to troubleshoot network issues and configure network devices

• CCNA certification is recommended...read more

Networking is the practice of connecting computers and other devices to share resources and information. IoT refers to the network of physical devices connected to the internet, allowing them to communicate and exchange data.

• Networking involves connecting devices to share resources and information

• IoT refers to physical devices connected to the internet

• IoT devices can communicate and exchange data

• Examples of IoT devices include smart thermostats, wearable fitness trackers, and...read more
