CISSP®- The CIA Triad - Part 2 - Confidentiality, Integrity, and Availability

The video tutorial covers networking models, focusing on the OSI and TCP/IP models. It explains the OSI model's seven layers, their functions, and their importance in networking. The tutorial also discusses the physical and data link layers in detail, including their components, security aspects, and common threats. Mnemonics for remembering the OSI layers and practical tips for exam preparation are provided.

Which two models are primarily discussed in the context of networking?

• OSI and TCP/IP models

• OSI and HTTP models

• OSI and FTP models

• TCP/IP and HTTP models

What is the primary purpose of the OSI model?

• To manage network security protocols

• To encrypt data during transmission

• To provide a physical connection between devices

• To standardize communication functions across different systems

Which mnemonic helps remember the OSI layers from layer 1 to 7?

• Every Good Boy Deserves Fruit

• All People Seem To Need Data Processing

• Cats Always Land On Their Feet

• Please Do Not Throw Sausage Pizza Away

What type of cable is considered more secure due to its resistance to eavesdropping?

• Twisted pair cable

• Coaxial cable

• Fiber optic cable

• Copper Ethernet cable

Which topology is NOT mentioned as part of the physical layer?

• Tree

• Star

• Ring

What is a MAC address primarily used for in a network?

• Encrypting data

• Identifying devices on a local network

• Routing data between networks

• Managing network security

What is a common threat to the data link layer involving MAC addresses?

• DNS Spoofing

• MAC Spoofing
