• Question 114:

  An Alcatel-Lucent 7750 SR is unable to locate a multicast source address in the multicast routing table. However, the source address is available in the unicast routing table. Which statement best describes the default RPF check behavior of the Alcatel-Lucent 7750 SR?

  A. The RPF check fails, as PIM relies exclusively on the multicast routing table by default.
  B. The RPF check fails, as it requires the source address be present in both the unicast and multicast routing tables.
  C. The RPF check succeeds, as PIM uses only the unicast routing table by default.
  D. The RPF check succeeds, as PIM uses the multicast routing table first, and then the unicast routing table by default.
  C. The RPF check succeeds, as PIM uses only the unicast routing table by default.
