LTIMindtree Technical Lead Interview Questions, Process, and Tips

BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between different networks. Metrics are values used to determine the best path for data to travel.

• BGP is used to route traffic between different autonomous systems (AS)

• Metrics in BGP include attributes like AS path length, local preference, and MED (Multi-Exit Discriminator)

• BGP uses these metrics to determine the best path for data...read more

OSPF (Open Shortest Path First) is a routing protocol used to determine the best path for data packets in a network.

• OSPF is a link-state routing protocol

• It uses Dijkstra's algorithm to calculate the shortest path

• Cost in OSPF is a metric used to determine the best path, calculated based on bandwidth of the link

• Cost is inversely proportional to the bandwidth, higher bandwidth means lower cost

• Example: A link with bandwidt...read more

Stateful firewall is a type of firewall that keeps track of the state of active connections and makes decisions based on the context of the traffic.

• Stateful firewalls monitor the state of active connections and make decisions based on the context of the traffic

• They keep track of the state of each connection by maintaining a state table

• Stateful firewalls can filter traffic based on the state of the connection, such as a...read more

TCP handshake is a process where two devices establish a connection by exchanging synchronization and acknowledgment packets.

• Three-way process involving SYN, SYN-ACK, and ACK packets

• Initiated by client sending a SYN packet to server

• Server responds with a SYN-ACK packet

• Client acknowledges with an ACK packet to complete the handshake

• Ensures reliable and orderly connection establishment

Upgrade Palo Alto involves planning, testing, and executing the upgrade process to ensure minimal downtime and maximum security.

• Plan the upgrade by reviewing release notes and compatibility matrix

• Backup current configuration and settings

• Test the upgrade in a lab environment before applying to production

• Schedule a maintenance window for the upgrade

• Monitor the upgrade process and verify functionality post-upgrade

• Create a map to store characters and their frequencies

• Iterate through the string and update the frequencies in the map

• Print characters with frequency greater than 1 as duplicates
