10+ Advantmed Interview Questions and Answers

Swapping two particular bits of an integer program.

• Use bitwise operators to get the values of the two bits to be swapped

• Use XOR operator to swap the bits

• Shift the bits back to their original positions

• Example: Swapping 2nd and 5th bits of 8 (1000) gives 32 (100000)

• Example code: num ^= (1 << bit1) | (1 << bit2);

IP packet header fields and their usage

• Version: indicates the IP version being used (IPv4 or IPv6)

• Header Length: specifies the length of the IP header

• Type of Service: used to prioritize packets

• Total Length: specifies the total length of the IP packet

• Identification: used to identify fragments of a larger packet

• Flags: used to control fragmentation

• Fragment Offset: used to reassemble fragmented packets

• Time to Live: specifies the maximum number of hops a packet can take

• Protocol: s...read more

TCP packet header fields and their usage

• TCP packet header consists of 20 bytes

• Fields include source and destination ports, sequence and acknowledgement numbers, flags, window size, and checksum

• Source and destination ports identify the endpoints of the connection

• Sequence and acknowledgement numbers are used for reliable data transfer

• Flags indicate the purpose of the packet, such as SYN, ACK, FIN, RST

• Window size is used for flow control

• Checksum is used for error detection

Security is important in a system to protect against unauthorized access, data breaches, and cyber attacks.

• Prevents unauthorized access to sensitive data

• Protects against data breaches and cyber attacks

• Ensures confidentiality, integrity, and availability of data

A program to implement a dictionary using an array of strings.

• Use an array of strings to store the words and their definitions.

• Implement functions to add, delete, and search for words.

• Consider using a hash table for faster search times.

Asymmetric routing in a network can lead to issues such as packet loss, out-of-order delivery, and inefficient use of network resources.

• Packet loss: When packets take different paths to reach their destination, some packets may get lost or dropped along the way.

• Out-of-order delivery: Asymmetric routing can cause packets to arrive at the destination out of order, leading to delays in data transmission.

• Inefficient use of network resources: Asymmetric routing can result in subop...read more

Blackhole issues with firewalls can cause slowness in forwarding traffic via MPLS and returning traffic via internet.

• Check firewall configurations to ensure proper routing of traffic

• Investigate blackhole issues to identify any dropped packets

• Consider implementing Quality of Service (QoS) policies to prioritize MPLS traffic

• Monitor network performance to detect any bottlenecks causing slowness

Writing code on notepad instead of an IDE

• Ensure proper indentation and formatting

• Use comments to explain code

• Compile and test code manually

• Save frequently to avoid losing work

Asymmetric routing occurs when data packets take different paths to reach their destination, leading to potential issues such as packet loss or out-of-order delivery.

• Asymmetric routing can occur in networks with multiple paths between source and destination.

• Issues with asymmetric routing include packet loss, out-of-order delivery, and potential security vulnerabilities.

• Examples of solutions to mitigate asymmetric routing issues include implementing symmetric routing policies ...read more

TCP is a reliable, connection-oriented protocol while UDP is a faster, unreliable, connectionless protocol.

• TCP ensures data delivery and error checking while UDP does not.

• TCP establishes a connection before data transfer while UDP does not.

• TCP is used for applications that require reliable data transfer like email, file transfer, etc. while UDP is used for applications that require speed like online gaming, video streaming, etc.

Reorder a linked list by alternating between the first and last elements

• Create two pointers, one at the beginning and one at the end of the linked list

• Iterate through the linked list, moving the first pointer to the next node and the second pointer to the previous node

• Adjust the pointers to reorder the linked list by alternating between the first and last elements

BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between autonomous systems on the internet.

• BGP is an exterior gateway protocol (EGP) that operates on TCP port 179.

• It is used to establish and maintain routing information among routers in different autonomous systems (ASes).

• BGP uses a path-vector algorithm to determine the best path for routing traffic.

• It supports both IPv4 and IPv6 networks.

• BGP allows routers to exchange information abo...read more
