R1. The output shows all BGP table entries on R1. How many iBGP-learned routes exist on
this router?

A company uses Routers R1 and R2 to connect to ISP1 and ISP2, respectively, with
Routers I1 and I2 used at the ISPs. R1 peers with I1 and R2; R2 peers with I2 and R1.
Assuming as many default settings as possible are used on all four routers, which of the
following is true about the next-hop IP address for routes R1 learns over its iBGP connection
to R2?

A company uses Routers R1 and R2 to connect to ISP1 and ISP2, respectively, with Routers
I1 and I2 used at the ISPs. R1 peers with I1 and R2; R2 peers with I2 and R1. R1 and R2 do
not share a common subnet, relying on other routers internal to the Enterprise for IP
connectivity between the two routers. Which of the following could be used to prevent
potential routing loops in this design? (Choose 2)

R1 is currently advertising prefixes 1.0.0.0/8, 2.0.0.0/8, and 3.0.0.0/8 over its eBGP
connection to neighbor 2.2.2.2 (R2). An engineer configures a prefix list (fred) on R1 that
permits only 2.0.0.0/8 and then enables the filter with the neighbor R2 prefix-list fred out
command. Upon exiting configuration mode, the engineer uses some show commands on
R1, but no other commands. Which of the following is true in this case?

Which of the following three BGP filtering methods enabled with the neighbor command will
filter BGP prefixes based on the prefix and prefix length? (Choose 3)

Which of the following commands causes a router to bring down BGP neighbor
relationships?

An engineer is preparing an implementation plan in which the configuration needs to
influence BGP’s choice of best patH. Which of the following is least likely to be used by the
configuration in this implementation plan?

Router R1 learns two routes with BGP for prefix 200.1.0.0/16. Comparing the two routes,
route 1 has a longer AS_Path Length, bigger MED, bigger Weight, and smaller Local
PreferencE. Which of the following is true about Router R1’s choice of best path for this
prefix?
