Layer 2 Data Link layer handles frames across the physical medium. Answer b is incorrect because bits are transferred at layer 1 Physical layer of the OSI model. Answer c is incorrect because layer 3 Network layer is commonly known as packets. Question 2 The correct answer is b. To enable RIP routing you issue the router rip global command. By default a Cisco router will send only RIP version I packets but will listen for RIP I and RIP II. Therefore if you only configure RIP I then RIP II packets will also be received and placed in the routing table but they will not be advertised by RIP. If you enable RIP II with the version 2 command then you ll only send and receive RIP II packets. Answer a is incorrect because router-rip is an invalid IOS command. Answer c is incorrect because the version 2 command is only applicable to the interface and does not satisfy the question. Answer d is incorrect because ip rip version 2 is an invalid IOS command. Answer e is incorrect because answer a is an invalid IOS command. Question 3 The correct answers are b and c. The unique bridge .
