Toku Voice Network Engineer Interview Questions and Answers

Q1. What do you know about routing?
Ans. 
Routing is the process of selecting the best path for network traffic to reach its destination.
• Routing involves determining the optimal path for data packets to travel from the source to the destination.

• Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.

• There are different types of routing protocols such as RIP, OSPF, EIGRP, and BGP.

• Static routing involves manually ...read more

Q2. What do you know about switching?
Ans. 
Switching is a networking technique used to forward data packets between devices on a computer network.
• Switching involves the process of receiving, analyzing, and forwarding data packets within a network.

• Switches operate at Layer 2 (Data Link Layer) of the OSI model.

• Switches use MAC addresses to determine the destination of data packets.

• Switches create separate collision domains and broadcast domains, improving network...read more

Q1. Routing tables in bgp and explain
Ans. 
BGP routing tables store information about routes to different networks and the best path to reach them.
• BGP uses a path-vector routing protocol to determine the best path for a packet to reach its destination.

• BGP routing tables contain information about the network prefixes, the next hop to reach them, and the path attributes that determine the best path.

• BGP routers exchange routing information with their neighbors to ...read more

Q3. What is nat and port number that can be used
Ans. 
NAT is a technique used to map private IP addresses to public IP addresses. Port numbers are used to identify specific applications.
• NAT stands for Network Address Translation

• It is used to allow devices with private IP addresses to access the internet using a public IP address

• Port numbers are used to identify specific applications or services

• Common port numbers include 80 for HTTP, 443 for HTTPS, and 22 for SSH

Q4. If neither the port range in source NAT pools nor the default port range are configured, the default single port range is 1024 through 63,487.
Ans. 
Default single port range when neither port range in source NAT pools nor default port range are configured.
• When neither port range in source NAT pools nor default port range are configured, the default single port range is 1024 through 63,487.

• This range is used for outbound traffic initiated by the device.

• It is important to configure the port range to avoid conflicts with other devices on the network.

• For example, if m...read more

Q5. What is mss in tcp explain
Ans. 
MSS in TCP refers to the maximum segment size, which is the largest amount of data that can be sent in a single TCP segment.
• MSS is negotiated during the TCP three-way handshake

• It is determined by the maximum transmission unit (MTU) of the network

• MSS can be adjusted by the sender or receiver using TCP options

• A smaller MSS can help prevent fragmentation and improve network performance

Q7. Troubleshooting pAcket drops
Ans. 
Packet drops can be caused by various factors. Troubleshooting involves identifying the root cause and implementing a solution.
• Check for network congestion or bandwidth limitations

• Verify if the packet is being dropped at the source or destination

• Inspect network devices for errors or misconfigurations

• Use packet capture tools to analyze the traffic

• Consider implementing Quality of Service (QoS) policies

• Update firmware or

Q8. Chekc port and duplex setting. Check mss and mtu Check link utilization
Ans. 
To check port and duplex setting, MSS and MTU, and link utilization in network engineering.
• Use command 'show interface' to check port and duplex setting.

• Use command 'ping -f -l ' to check MTU.

• Use command 'netstat -s' to check MSS.

• Use command 'show interface' or 'show interfaces utilization' to check link utilization.
