JNCIA-DC: Juniper Networks Certified Associate – Data Center (2021) — Question 23

Mist has detected a bad cable.
What are two ways that Marvis determined this result? (Choose two.)

Answer options

• A. It identified network loops.
• B. It identified port flapping.
• C. It identified interface errors.
• D. It identified a missing VLAN.

Correct answer: B, C

Explanation

Marvis can determine a bad cable by identifying port flapping, which indicates instability in the connection, and by recognizing interface errors, which suggest problems in data transmission. Network loops and missing VLANs do not directly indicate a faulty cable, making options A and D incorrect.
