CCNP Certification / BSCI Exam:
DUAL has discovered four latent paths to a faraway network, near the succeeding metrics: PathA, 1500. PathB, 1500. PathC, 2600. PathD, 3100. What dictate will let EIGRP to use the archetypal iii paths in need victimization the fourth?
Answer: departure 2 would do the job. Any track near a metric of 3000 or humiliate will be utilized; location it to 3 would take PathD into the mathematical statement.
CCNP Certification / BCMSN Exam:
What is the basic intention of IEEE 802.3ac?
Answer: The IEEE 802.3ac common allows the maximum frame physical property to be extended to 1522 bytes, which mode the dot1q 4-byte heading doesn't make happen snags in transmission.
