Network Support Engineer Interview Questions

Break the balls into the following groups: (1,2,3),(4,5,6),(7,8) Step 1. Weigh (1,2,3) against (4,5,6) Two possible outcomes: The two groups are equally heavy. (Case A) One of these groups is heavier than the other. (Case B) Case A --> Weigh 7 against 8. Now you have identified the heavier ball in 2 weighing. Case B --> Take the heavier group (assume it to be (1,2,3)), take any two balls and weigh them against each other. Either one of these is heavier else the third ball is.

Is there anyway you could go into more detail about the technical role play?

Hi could you just talk about a question about the technical role-play. I would really appreciate.

Hey can you tell me what other basic questions and scenarios they asked in technical round ? My technical round is scheduled for next week so that will be helpful

Hey!! Can you tell me what do they ask in the first phone interview? Are they asking any technical stuff in the first round itself?

Need help

DHCP Relay should be enabled

Can you give an idea on what they asked during the written assignment and the last face to face interview in the SF office

For this question, I responded with the 3-way handshake and briefly described its process, including which segment header fields are used and how the sequence/acknowledgement numbers are incremented.

sync, sync-ack, ack

Answers actually depend on topologies given for troubleshooting.

Could you brief about the topology you got during on-site interview?

Routing protocol specifies how routers perform the network connectivity algorithms and distribute information across the nodes. Categorized as static, default and dynamic routing protocols. Link-state and distance vector are dynamic routing protocols. Distance vector routing protocols are based on "routing by rumour" principle. ie perform its routing operations based on the communication with the directly connected neighbor and does not have an overview or full knowledge of the entire network, slower to converge and good for the small networks, This category includes RIP and EIGR. while Link State routing protcols have an overview (exact map) of the entire network. I know everything that moves. They have information about each link ( current status: up/down, speed, etc). This includes OSPF and IS-IS protocols. it converges faster, updates are triggered by events and uses hello to connects to its neighbor. NB: You can expatiate further on the behavior of each routing protocols such as the OSPF on link state hello messages, updating its routing table and calculating the shortest path using the Bellman-Ford algorithm. The RIP update time every 30-sec repetitively, learning the routes of the directly connected neighbor and storing of the information its routing table.

Access and Trunk, access allows only one VLAN to pass through, trunk allows multi VLANs. Recommended device- switch access and switch- switch trunk
