A network administrator is inspecting a Cisco IOS switch interface connected to a server. The output of the `show interfaces GigabitEthernet 0/1` command reveals a high number of Frame Check Sequence (FCS) errors and late collisions. Which two physical or data-link layer issues are the most likely causes of these specific interface counter statistics? (Select two.)
- Physical cable damage, excessive electromagnetic interference, or faulty connectors corrupting bits in transit.Cevap
- A duplex mismatch between the switch port and the connected device, causing the half-duplex side to transmit while receiving data after the slot time.Cevap
- CA native VLAN identifier mismatch between the switch port and the server's network adapter.
- DUsing a straight-through Ethernet cable between two switch ports with Auto-MDIX manually disabled.
Cevap
Physical cable damage or interference causing bit corruption (FCS errors) and a duplex mismatch causing collision detection after the 64-byte window (late collisions).
Physical cable damage or electrical interference causes bits to flip in transit, resulting in Frame Check Sequence (FCS) checksum mismatches. A duplex mismatch causes the half-duplex end to attempt transmission while the full-duplex end sends traffic, producing late collisions after the initial 64-byte collision window.
