user@router# show protocols bgp
group myEBGP {
import noTransit;
peer-as 318;
neighbor ;
}
[edit]
user@router# show policy-options
policy-statement noTransit {
term rejectAS1524 {
from as-path AS1524;
then accept;
}
}
as-path AS1524 *1524*;
To block transit traffic from AS1524, you have configured and committed the configuration as shown in the exhibit. However, traffic from AS1524 is still flowing through your AS.
Which two changes must you implement to resolve the problem? (Choose two.)
A. Change the peer AS in the myEBGP group to 1524.
B. Change the as-path regex to “.* 1524 .*”
C. Change the then condition from accept to reject.
D. Change the import noTransit statement to export noTransit.
Answer: BC

user@router# show protocols bgp
group ebgp {
import block-martian;
family inet {
unicast;
}
peer-as 65530;
neighbor 172.22.135.37;
}
[edit]

route-filter 191.255.0.0/16 orlonger reject;
route-filter 192.0.0.0/24 orlonger reject;
route-filter 223.255.255.0/24 orlonger reject;
route-filter 240.0.0.0/4 orlonger reject;
}
}
then reject;
}
[edit]
You have established a peering with an EBGP neighbor, but the peer’s 172.0.0.0/8 routes show as hidden.
Referring to the exhibit, what is causing the problem?
A. The ebgp group configuration is missing an export policy needed to accept the routes.
B. The route-filter used in the import policy is rejecting the 172.0.0.0/8 routes.
C. The import policy is rejecting all routes from the EBGP peer.
D. The ebgp group configuration for family inet unicast is causing a route mismatch.
Answer: C
QUESTION 23
Click the Exhibit button.
A customer is not seeing direct routes in the LDP database.
Referring to the exhibit, which configuration is required on router R2 to advertise labels corresponding to direct routes?
A. set protocols ldp export connected-routes
B. set protocols ldp egress-policy connected-routes
C. set protocols ldp import connected-routes
D. set protocols ldp igp-synchronization
Answer: B
QUESTION 24
Click the Exhibit button.
user@router# show policy-options
policy-statement isis-export {
term 1 {
from {
route-filter 172.22.135.0/8 orlonger reject;
route-filter 172.22.135.0/24 orlonger accept;
}
then reject;
}
term 2 {
from {
protocol isis;
route-filter 10.0.0.0/8 longer;
route-filter 10.0.0.0/24 longer accept;
}
then reject;
}
}
You are asked to block the 10.0.0.0/8 IS-IS routes from being redistributed into other protocols.
You still want the existing 10.0.0.0/25 IS-IS routes to continue to be redistributed. You have applied an export policy as shown in the exhibit, however, the 10.0.0.0/8 routes are still being redistributed.
What is causing the problem?
A. The policy can only evaluate a single route-filter match for each term.
B. When the route-filter matching process occurs, the least specific route-filter prefix evaluation is
rejecting the routes.
C. When the route-filter matching process occurs, the most specific route-filter prefix evaluation is
accepting the routes.
D. Term 2 should be inserted before term 1.
Answer: C
QUESTION 25
Click the Exhibit button.
user@P1# show policy-options policy-statement imp-bgp1 term 1
{
from {
protocol bgp;
route-filter 0.0.0.0/0 orlonger;
}
then {
preference 245;
}
}
user@P1# show protocols bgp group IBGP
local-address 172.24.255.1;
family inet {
unicast;
}
family inet-vpn {
unicast;
}
cluster 172.24.255.1;
peer-as 50;
neighbor 172.24.255.3;
neighbor 172.24.255.2 {
local-preference 200;
import imp-bgp1;
}
neighbor 172.24.255.4;
The operator of the network shown in the exhibit wants to make 172.24.255.2 the preferred path for routes. However, the router still prefers a different peer.
What is the problem?
A. The default protocol preference is less preferred than the preference set in the policy.
B. The import policy is setting the protocol preference less preferred than the default.
C. The default protocol preference is more preferred than the preference set in the policy.
D. The local preference setting is below the default.
Answer: C

Referring to the exhibit, the bandwidth reservation on interface ge-5/3/1.0 appears to be incorrect.
Which statement is true?
A. RSVP reservation is unidirectional; bandwidth is reserved only on the egress interface of an LSP.
B. LSP statistics shows 0 packets; no reservation exists on the interface.
C. The fixed filter (FF) reservation style should be configured instead of the shared explicit (SE) style.
D. Interface ge-5/3/1.0 has no admin group configured.
Answer: A
