IPSec (Internet Protocol Security)   is a suite of protocols designed to secure communications over IP networks. It provides data confidentiality, integrity, and authentication, ensuring secure data transmission. Here's a breakdown of the key components: 1. Authentication Header (AH) Purpose:  Provides data integrity, data origin authentication, and an optional replay protection service. How it works: Calculates a message authentication code (MAC) based on the entire IP packet (including the outer IP header). Appends the MAC to the packet. The recipient verifies the MAC to ensure data integrity and authenticity. Benefits: Ensures that data hasn't been tampered with during transit. Verifies the source of the data. Limitations: Doesn't provide data confidentiality (encryption). 2. Encapsulating Security Payload (ESP) Purpose:  Provides data confidentiality (encryption), data integrity, and data origin authentication. How it works: Encrypts the entire IP packet (except for s...

  S/STP: Screened Shielded Twisted Pair Cable S/STP  stands for  Screened Shielded Twisted Pair . It's a type of Ethernet cable that combines two layers of shielding for enhanced protection against electromagnetic interference (EMI) and crosstalk.   Structure of S/STP Cable: Twisted Pairs:  Each pair of copper wires is twisted together to reduce crosstalk.     Individual Pair Shielding:  Each pair is individually wrapped in a foil shield, providing additional protection against interference.     Overall Screen:  A braided mesh of metal strands surrounds all the shielded pairs, creating a second layer of shielding.  Benefits of S/STP: Superior EMI/RFI Protection:  The double shielding significantly reduces the impact of external electromagnetic interference, ensuring reliable data transmission even in noisy environments.     Reduced Crosstalk:  The shielding minimizes interference between the individual pairs...

  CCST Networking sample questions for practice: Question 1: Which layer of the OSI model is responsible for end-to-end reliability and flow control? A. Transport Layer B. Network Layer C. Data Link Layer D. Physical Layer Answer: A. Transport Layer Explanation: The Transport Layer (Layer 4) is responsible for reliable end-to-end communication between devices. It uses protocols like TCP to ensure data integrity and flow control. Question 2: What is the purpose of the ARP protocol? A. To resolve IP addresses to MAC addresses B. To resolve MAC addresses to IP addresses C. To route packets between networks D. To provide network security Answer: A. To resolve IP addresses to MAC addresses Explanation: The Address Resolution Protocol (ARP) is used to map IP addresses to physical (MAC) addresses. This is essential for devices on the same network to communicate with each other. Question 3: Which network topology provides the highest level of redundancy? A. Bu...
