A network engineer is investigating a performance degradation on a 1 Gbps Ethernet link between a router and a switch. The engineer runs 'show interfaces ge-0/0/0 extensive' and sees a high number of 'Input errors' with a large count of 'giants' and 'runt' frames. The CRC error count is zero. What is the most likely cause of these errors?

A duplex mismatch or faulty cable causing framing errors

An MTU mismatch between the router and the switch

A faulty transceiver on the router's interface

A software bug on the switch causing it to send malformed frames

A network engineer is troubleshooting intermittent connectivity between two buildings connected by a fiber link. The engineer runs 'show interfaces ge-0/0/0 extensive' and notices that the 'Input errors' counter is increasing, with a large number of 'CRC errors' and 'framing errors' on the same interface. The physical link is up and the output errors counter is zero. What is the most likely cause of this issue?

An MTU mismatch between the two connected devices

A faulty or dirty fiber optic cable or connector

Excessive broadcast traffic on the segment

A duplex mismatch between the two connected devices

Why is it important to monitor interface errors on a regular basis?

To verify that the routing protocol is functioning correctly.

To ensure that the interface is administratively up.

To determine the IP address of the interface.

To detect physical layer problems early before they cause significant network degradation.

In Junos OS, which statement accurately describes the purpose of interface statistics?

They display the MAC address and IP address assigned to the interface.

They track the number of packets and bytes transmitted and received, along with error counts, to help monitor interface health.

They list the routing protocols enabled on the interface and their current state.

They provide a real-time view of the current configuration of the interface.

Part of the Operational Monitoring and Maintenance domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–2 from this objective — we provide 16 practice questions to prepare you well beyond it.
