Refer to the exhibit. What is the issue with the interface GigabitEthernet0/0/1?
The interface GigabitEthernet0/0/1 is experiencing a duplex mismatch issue. This is evident from the fact that the interface is operating in half-duplex mode, which is unusual for a Gigabit Ethernet connection that typically operates in full-duplex. Additionally, the presence of 50 collisions and the issue of 'line protocol is down' further corroborate that there is a duplex mismatch occurring on this interface.
B because line protocol is down
Half Duplex, 1000Mbps" is unusual because GigabitEthernet typically operates in full duplex. This discrepancy could indicate a duplex mismatch, which can happen when one side of a connection is set to full duplex and the other side to half duplex, or when one side is set to auto-negotiate and the other is manually set to a fixed speed or duplex setting. "50 collisions" is another indicator that points to a duplex mismatch. Collisions should not occur on full-duplex links. On a Gigabit interface, it's even more uncommon because GigabitEthernet should only operate in full duplex.
B because line protocol is down
A. Port security: There’s no indication that port security is causing the issue. B. Cable disconnect: The interface is up, so the cable is likely connected. If the cable were disconnected, the interface would likely be down. C. High throughput: There’s no indication of high throughput issues; the output rate is low. D. Duplex mismatch: The interface is set to half-duplex, which is unusual for a Gigabit Ethernet connection (which typically runs in full-duplex). The presence of collisions also suggests a duplex mismatch, as collisions are common in half-duplex environments when one side is configured incorrectly. Based on the provided information and the common symptoms of duplex mismatches (e.g., collisions, line protocol down), the most likely issue with the interface GigabitEthernet0/0/1 is: D. Duplex mismatch
it´s B line protocol is down
B Line protocol down == no cable, bad cable, speed mismatch, etc. Line protocol down(err disabled) == Port security has disabled the interface this is a good video that made me understand most of this: https://www.youtube.com/watch?v=tZbayqSJISU
B; the line protocol is down. As for the other answers: A -> Incorrect; if it were a port security violation, the line protocol would read "down (err-disabled)". C -> Incorrect; the line is down, there's no throughput. D -> Partially correct; interface is configured as half-duplex and there's a number of collisions. However, since the interface is down, it's not the relevant issue.
I think it is D, cable disconnect is not the exact word I would use. cable issue maybe.
input error: duplex mismatch, bad cables or NIC problems. option B sounds like completely disconnected, it will cause line down/proto down
changed to B because collision is relatively low and high interface resets
When cable is disconnected, interface is in down/down state. In his case it is up/down. Therefore D is correct answer. Rest are invalid.
