   A network engineer is designing a network for a small office. The engineer wants to ensure that devices on the same LAN can communicate using MAC addresses, while devices on different LANs communicate using IP addresses. Which statement correctly describes the roles of MAC and IP addresses in this design?

   • AMAC addresses are used for local delivery within a LAN, while IP addresses are used for delivery across networks
   • BMAC addresses are assigned by the network administrator, while IP addresses are burned into the NIC
   • CIP addresses are used for local delivery, while MAC addresses are used for delivery across networks
   • DBoth MAC and IP addresses are used for local delivery, but only MAC addresses are used across networks

   Which statement best describes the role of a frame in local network delivery?

   • AA frame encapsulates the packet and uses MAC addresses to deliver data within the same network segment.
   • BA frame is the data unit used to route packets between different networks.
   • CA frame contains only the application data without any addressing information.
   • DA frame is used to establish end-to-end communication between applications.

   A network administrator is explaining to a new technician how data is encapsulated as it moves down the TCP/IP stack. The technician asks, 'At which layer is a packet encapsulated into a frame?' Which answer is correct?

   • ATransport layer
   • BApplication layer
   • CNetwork access layer
   • DInternet layer

   A network engineer is examining a frame captured on an Ethernet LAN. The frame contains source and destination MAC addresses, but the engineer notes that the frame does not contain any IP address information. Which statement best describes why this is expected?

   • AThe frame is from a switch that only operates at Layer 2 and strips IP addresses
   • BThe frame is carrying a packet that has already been removed by the receiving host
   • CThe frame is at the data link layer and uses MAC addresses for local delivery, while IP addresses are inside the encapsulated packet
   • DThe frame is a broadcast frame and therefore does not need IP addresses

   A network instructor is explaining the differences between the OSI and TCP/IP models to a class. The instructor states that one model is more practical for describing modern internet protocols, while the other is more useful for troubleshooting and teaching. Which statement accurately compares the two models?

   • AThe TCP/IP model has seven layers, while the OSI model has four layers; the OSI model is more practical
   • BThe OSI model has seven layers, while the TCP/IP model has four layers; the TCP/IP model is more aligned with actual protocol implementations
   • CBoth models have the same number of layers, but they name them differently
   • DThe OSI model is used for routing, while the TCP/IP model is used for switching
