Which version or versions of NetFlow support MPLS?
MPLS-aware NetFlow uses the NetFlow Version 9 export format. MPLS-aware NetFlow exports up to three labels of interest
from the incoming label stack, the IP address associated with the top label, as well as traditional NetFlow data.
Which three algorithms can you configure with the ip cef load-sharing algorithm command? (Choose three.)
B C E
The following load-balancing algorithms are provided for use with Cisco Express Forwarding traffic. You select a load-
balancing algorithm with the ip cef load-sharing algorithm command.
Original algorithm--The original Cisco Express Forwarding load-balancing algorithm produces distortions in load sharing
across multiple routers because the same algorithm was used on every router. Depending on your network environment, you
should select either the universal algorithm (default) or the tunnel algorithm instead.
Universal algorithm--The universal load-balancing algorithm allows each router on the network to make a different load
sharing decision for each source-destination address pair, which resolves load-sharing imbalances. The router is set to
perform universal load sharing by default. Tunnel algorithm--The tunnel algorithm is designed to balance the per-packet
load when only a few source and destination pairs are involved. Include-ports algorithm--The include-ports algorithm
allows you to use the Layer 4 source and destination ports as part of the load-balancing decision. This method benefits traffic
streams running over equal cost paths that are not load shared because the majority of the traffic is between peer addresses
that use different port numbers, such as Real-Time Protocol (RTP) streams. The include-ports algorithm is available in Cisco
IOS Release 12.4(11)T and later releases.
What is the benefit of deploying IPv6 in a campus network using dual stack mode?
Deploying IPv6 in the campus using the dual-stack model offers several advantages over the hybrid and service block
The primary advantage of a dual stack model is that it does not require tunneling within the campus network.
The dual stack model runs the two protocols as ships in the night, meaning that IPv4 and IPv6 run alongside one another
and have no dependency on each other to function except that they share network resources. Both have independent
Which command sequence can you enter a router to configure Unicast Reverse Path Forwarding in loose mode?
Refer to the exhibit.
Routers R2, R3, R4, and R5 have OSPF enabled.
What should be configured on the routers in area 1 to ensure that all default summary routes and redistributed EIGRP routes
will be forwarded from R6 to area 1, and only a default route for all other OSPF routes will be forwarded from R5 to area 1.

receive an IP address from the DHCP server?
Refer to the exhibit. Which option prevents routing updates for 10.255.255.0/30 from being sent to the DHCP router, while
still allowing all other routing update messages?
