Is Your BGP Knowledge at Cisco ENARSI Level?

Examine the BGP configuration shown. Which statement regarding this configuration is true?

R1:
ip prefix-list MYLIST seq 5 permit 10.10.10.0/24
!
route-map MYMAP permit 10
match ip address prefix-list MYLIST
set as-path prepend 65000

If this route map is applied outbound to a BGP neighbor, non 10.10.10.0/24 prefixes will be filtered
This configuration will return an error as AS Path Prepending is not permitted against internal AS numbers
The AS-PATH is prepended three times with the value 65000
This route map may only be applied in the inbound direction

Examine the BGP configuration shown. Which statement regarding this configuration is true?

R1:
ip prefix-list MYLIST seq 5 permit 10.10.10.0/24
!
route-map MYMAP permit 10
match ip address prefix-list MYLIST
set as-path prepend 65000

This configuration permits R1 to prefer a certain path for outbound traffic
This configuration permits R1 to prefer a certain path for inbound traffic
This configuration impacts the origin attribute
This configuration impacts the next hop attribute

You have noticed that a prefix for your BGP topology is not being advertised to peers. This prefix is in the BGP table, but you note that it is not marked as a best path. What is the most likely issue?

There is no IGP path to the next hop
There is not a matching prefix in the IP routing table
The prefix was learned from an iBGP peer
The metric has been exceeded for the prefix

You have run the show ip bgp summary command and you have discovered the following output:

10.0.0.1 4 200 965 948 0 0 0 00:02:24 Idle (PfxCt)

What is the most likely reason for this idle state?

The holdtime has been exceeded
There has been an authentication mismatch
There is an out of memory condition
The BGP maximum-prefix feature is being utilized

You have decided to use weight in order to influence outbound traffic flows with BGP. What should be your approach?

You should set the weight value for outbound prefix advertisements; make sure the weight is lower for preferred paths
You should set the weight value for inbound prefix advertisements; make sure the weight is lower for preferred paths
You should set the weight value for inbound prefix advertisements; make sure the weight is higher for preferred paths
You should set the weight value for outbound prefix advertisements; make sure the weight is higher for preferred paths
