A network administrator is managing a network that deploys a multicast service. The administrator has
multiple streams successfully being routed by PIM-DM in the network. The administrator then adds a new stream with a destination address of 239.0.0.1. However, clients who have not joined the stream are receiving it.
What should the administrator do to fix this problem?
MAC/IP overlap. 239.0.0.1 would be the same MAC for 224.0.0.1. 224.0.0.0/24 is always flooded over every port.
An administrator has an aggregation layer of 8325CX switches configured as a VSX pair. The administrator is
concerned that when OSPF network changes occur, the aggregation switches will respond to the changes
slowly, and this will affect network connectivity, especially VoIP calls, in the connected access layer switches.
What should the administrator do on the aggregation layer switches to alleviate this issue?D18912E1457D5D1DDCBD40AB3BF70D5D
'BFD tests the connectivity between two IP addresses in a BFD session. BFD reports when connectivity is lost. The router (or routing switch) can then use that information to take the appropriate actions, depending on the functions to which you have tied BFD'
Examine the attached diagram
Two AOS-CX switches are configured for VSX at the access layer, where servers attached to them. An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the switches.
What is correct about access from the servers to the Core?
A company has recently upgraded their campus switching infrastructure with AOS-CX switches. They have
implemented 802.1X authentication on access ports where laptop and IOT devices typically connect. An
administrator has noticed that for POE devices, the AOS-CX switch ports are delivering the maximum wattage
to the port instead of what the device actually needs.
Concerned about this waste of electricity, what should the administrator implement to solve this problem?
