Movate Network Engineer Interview Questions, Process, and Tips

L3 switch is a switch with routing capabilities while a router is a dedicated device for routing.

• L3 switch operates at layer 2 and layer 3 of the OSI model while a router operates only at layer 3.

• L3 switch can perform routing functions like a router but also has the ability to switch frames between ports like a switch.

• Routers are typically used to connect different networks while L3 switches are used to segment a netwo...read more

VLAN leakage is when traffic from one VLAN is mistakenly sent to another VLAN.

• VLAN tagging should be properly configured to prevent leakage

• Access control lists (ACLs) can be used to restrict traffic between VLANs

• VLAN pruning can be used to limit the number of VLANs that are propagated throughout the network

• Examples of VLAN leakage include a misconfigured switch port or a compromised network device

TCP 3 way handshake is a process of establishing a connection between two devices over a network.

• The client sends a SYN packet to the server

• The server responds with a SYN-ACK packet

• The client sends an ACK packet to the server to confirm the connection

• This process is used to ensure reliable communication between devices

Questions related to TCP/IP layers, subnet mask, VLAN, ARP, port number, IP and MAC addresses.

• Transport layer is needed for reliable communication and error correction.

• Subnet mask is used to identify the network and host portions of an IP address.

• VLAN is needed for network segmentation and security.

• Switches and routers send packets or frames based on destination IP address.

• Types of ARP include ARP request and ARP reply...read more
