| Question ID 15983 | Which three statements accurately describe Layer 2 Ethernet switches? (Choose three.) |
| Option A | Spanning Tree Protocol allows switches to automatically share VLAN information. |
| Option B | Establishing VLANs increases the number of broadcast domains. |
| Option C | Switches that are configured with VLANs make forwarding decisions based on both Layer 2 and Layer 3 address information. |
| Option D | Microsegmentation decreases the number of collisions on the network. |
| Option E | In a properly functioning network with redundant switched paths, each switched segment will contain one root bridge with all its ports in the forwarding state. All other switches in that broadcast domain will have only one root port. |
| Option F | If a switch receives a frame for an unknown destination, it uses ARP to resolve the address. |
| Correct Answer | B,D,E |
| Question ID 15984 | Refer to the exhibit.
Host A pings interface S0/0 on router 3. What is the TTL value for that ping? |
| Option A | 252 |
| Option B | 253 |
| Option C | 254 |
| Option D | 255 |
| Option F | Answer : B Explanation: From the CCNA ICND2 Exam book: Routers decrement the TTL by 1 every time they forward a packet; if a router decrements the TTL to 0, it throws away the packet. This prevents packets from rotating forever. I want to make it clear that before the router forwards a packet, the TTL is still remain the same. For example in the topology above, pings to S0/1 and S0/0 of Router 2 have the same TTL. The picture below shows TTL values for each interface of each router and for Host B. Notice that Host A initializes ICMP packet with a TTL of 255:
