Juniper JN0-692 real exam prep : Service Provider Routing and Switching Support, Professional

You have applied a customized EXP rewrite rule on router R1 on the egress of the interface connecting to router R2. You want to verify if it is working properly. Which two methods would you use to accomplish this task? (Choose two.)

• A. Use the traceroute utility.
• B. Apply a rewrite rule on the ingress of R2 for packets coming in from R1 and count those packets for the new EXP values with a firewall filter as they leave R2.
• C. Use an output filter on R1 that matches and counts on various EXP values on packets going to R2.
• D. Use an input firewall filter on R2 that matches and counts on various EXP values on packets coming from R1.

ISIS Trace options :
May 21 20:58:25.3 ERROR: interface ae1.12 MTU 1200 is too small
Interface configuration :
user@router# show interfaces ae1.12
vlan-id 12;
family inet {
address 10.1.1.1/24;
}
family iso {
mtu 1200;
}
-- Exhibit --
An IS-IS adjacency does not come up between two directly connected routers.
Referring to the exhibit, what would cause this problem?

• A. MTU has been configured for family iso instead of family inet.
• B. The MTU configured on the interface is higher than the maximum MTU supported by IS-IS.
• C. The MTU configured on the interface is less than the IS-IS minimum MTU requirement.
• D. The neighboring router has a larger MTU configured.

Which two statements are true about the OSPF 2-Way state? (Choose two.)

• A. It is the normal state for neighbors that are the DR and BDR.
• B. It indicates that communication between two neighbors is bidirectional.
• C. It is the normal state for two neighbors that are neither the DR nor BDR.
• D. It indicates that a device cannot accept any more full adjacencies.

You have been asked to troubleshoot an OSPF problem where the OSPF session will not establish.
According to the outputs shown in the exhibit, which statement is true?

• A. The dead-interval is set too low.
• B. The hold-time interval is set too low.
• C. There is an MTU mismatch.
• D. The hold-time interval is set too high.

Referring to the exhibit, you have been asked to troubleshoot a class of service (CoS) problem where an interface is dropping some expedited-forwarding (EF) packets during congestion.
Which two statements describe what is happening? (Choose two.)

• A. The default CoS output scheduler is in use.
• B. EF packets are dropped because the ipprec-compatibility classifier maps EF packets to queue
  1.C. The default CoS input scheduler is in use.
• C. EF packets are dropped because the exp-default classifier maps EF packets to queue 1.
