Cisco Designing Cisco Enterprise Networks Sample Questions (Q45-Q50):

NEW QUESTION # 45
Which statements about RSPAN are true? (Choose two.)

Answer: A,F

Explanation:
The RSPAN VLAN carries SPAN traffic between RSPAN source and destination sessions. It has these special characteristics:
All traffic in the RSPAN VLAN is always flooded.
No MAC address learning occurs on the RSPAN VLAN.
RSPAN VLAN traffic only flows on trunk ports.
RSPAN VLANs must be configured in VLAN configuration mode by using the remote-span VLAN configuration mode command.
STP can run on RSPAN VLAN trunks but not on SPAN destination ports.
An RSPAN VLAN cannot be a private-VLAN primary or secondary VLAN.
For VLANs 1 to 1005 that are visible to VLAN Trunking Protocol (VTP), the VLAN ID and its associated RSPAN characteristic are propagated by VTP. If you assign an RSPAN VLAN ID in the extended VLAN range (1006 to 4094), you must manually configure all intermediate switches.
It is normal to have multiple RSPAN VLANs in a network at the same time with each RSPAN VLAN defining a network-wide RSPAN session. That is, multiple RSPAN source sessions anywhere in the network can contribute packets to the RSPAN session. It is also possible to have multiple RSPAN destination sessions throughout the network, monitoring the same RSPAN VLAN and presenting traffic to the user. The RSPAN VLAN ID separates the sessions.

An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state.
Which solution limits impact on the device and provides the required data?

Answer: D

Explanation:
There are two types of subscriptions: periodic and on-change. With periodic subscription, data is streamed out to the destination at the configured interval. It continuously sends data for the lifetime of that subscription. With on-change, data is published only when a change in the data occurs such as when an interface or OSPF neighbor goes down.
