Common Technical System Administrator Interview Questions

Difference between TCP and UDP protocols

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both protocols used in computer networking.

  • TCP is a connection-oriented protocol that ensures reliable, ordered delivery of data packets. It establishes a connection between the sender and receiver before transmitting data, and it guarantees that the data will be delivered without errors.

  • On the other hand, UDP is a connectionless protocol that does not establish a connection before transmitting data. It is faster but less reliable than TCP since it does not guarantee delivery or ensure packet ordering.

RAID and its different levels

RAID (Redundant Array of Independent Disks) is a technology used to combine multiple physical hard drives into one logical unit for improved performance, redundancy, or both.

  • RAID 0: Provides increased performance by striping data across multiple drives but offers no fault tolerance.

  • RAID 1: Mirrors data across two drives for redundancy, ensuring that if one drive fails, the other can still function.

  • RAID 5: Distributes parity information across all drives to provide fault tolerance with optimized storage capacity.

  • RAID 10: Combines mirroring (RAID 1) and striping (RAID 0) for both performance and redundancy.

DHCP and how it works

DHCP (Dynamic Host Configuration Protocol) is a network protocol that automatically assigns IP addresses to devices on a network.

  • When a device connects to a network, it sends out a DHCP discover message to find available DHCP servers.

  • The DHCP server responds with an offer containing an IP address lease along with additional configuration parameters such as subnet mask and default gateway.

  • The device then requests the offered IP address by sending a DHCP request message.

  • Finally, the server acknowledges the request by sending a DHCP acknowledgment message confirming the lease of the IP address.
