質問 2

Refer to the exhibit. The service provider operations team was alerted that hub site traffic from BGP AS
65101 to AS 65201 uses a non-primary path via the R5-R6 link. IBGP peering between R1 and R2 is up. and no fiber failure has been reported on the R2-R3 link The team determined that the traffic flow between
10.10.10.1 and 192.168.30.1 is not considering the R1-R2-R3-R4 path. Which action resolves this issue?

（A）Add metric 5 with BGP neighbor 10.10.10.6 on R5for receiving routes.

（B）Change the metric attribute to 20 with neighbor 10.10.10.5 on R1.

（C）Set the local-preference to the default value with BGP neighbor 10 10.10.3 on R2 for receiving routes.

（D）Change the local-preference attribute to 50 with neighbor 10.10 10 5 on R1

質問 3

Refer to the exhibit.

The UserA device fails to recede IPTV streaming traffic from the source While debugging the issue a network engineer finds that routers RB and RC receive the multicast traffic normally RC receives subscription messages from UserA to join the IPTV stream Which action must the engineer lake on router RA to correct this problem?

（A）Change ip igmp version 2 to ip igmp version 3 on interface GigabitEthernet 1/0.

（B）Configure ip pim bidir-enable in global mode and add ip pim rp-address 10.10.10.3

質問 6

Refer to the exhibit. Users at the branch office on R1 reported issue with an application at the home office on R4. While troubleshooting the issue, a network engineer determined that
* The branch-office users can connect to the home office.
* The IS-IS adjacencies between R1 and R2 and R1 and the branch office are up.
* Traffic from R1 to the R2 10.20.1.0/24 network is moving normally.
* The application at the home office is experiencing packet drops on the connection to the Branch, and R3 cannot reach the R1 172.16.10.0/24 network.
Which action resolves the issues?

（A）Redistribute static connected routes in IS-IS on router RI.

（B）Configure the IS-IS core instance on the R2 GigabitEthernet0/1 interface.

（C）Configure the IS-IS core instance on the RI GigabitEthernet0/3 interface.

（D）Redistribute static connected routes in IS-IS on router R4.

（A）TenGigE0/2 interface provides the alternate path

（B）TenGigE0/1 interface provides the alternate path

質問 9

What are two major differences between OSPF and IS-IS routing protocols? (Choose two.)

（A）The OSPF default administrative distance is 115 and the default administrative distance for IS-IS is 110

（B）OSPF partially refreshes the LSA database every 30 minutes, and IS-IS refreshes the complete database table every 60 minutes

（C）The OSPF DR role can be pre-empted only when the active DR goes down, but the IS-IS DR role can be taken by a router with higher priority at any time

（D）An OSPF-enabled router is part of only one area but an IS-IS-enabled router is part of multiple areas

（E）OSPF uses IP protocol 89 foe encapsulation and IS-IS uses an IEEE 802 3 standard-based protocol foe encapsulation
