Referring to the exhibit, how would this task be accomplished?
A. Configure the set protocols isis ignore-attached-bit parameter on router R5.
B. Configure the set protocols isis ignore-attached-bit parameter on routers R3 and R4.
C. Configure the set protocols isis level 1 wide-metrics-only parameter on router R5.
D. Configure the set protocols isis level 2 wide-metrics-only parameter on routers R3 and R4.

質問 4：
Click the Exhibit button.

You administer AS 65000, and have deployed a route reflector (RR1) in your network as shown in the exhibit. The traffic between AS 65001 and AS 65002 is going through the route reflector, even though it is not the best path.
What will solve this problem?
A. Change the IGP metric so it is lower on the preferred path.
B. Remove the nhs policy.
C. Change the LOCAL_PREF so that it uses the preferred path.
D. Change the originator to be the preferred path.
正解：B

質問 5：
How does Juniper Networks use selective BGP route damping to help stabilize the network?
A. The damping max-suppress timer is set to the lowest possible value by default.
B. The damping decay half-life holds down peer links for a defined measure of time to prevent route table reconvergence.
C. The figure-of-merit value measures route stability by advertisement and withdrawal.
D. Aggressive IGP hold timers prevent the routes from entering and exiting the BGP route selection process.
正解：C

質問 6：
You are asked to deploy VPLS in your network as a new service for several customers, and you must identify the configuration and provisioning requirements for your customers. Which two statements are correct in this scenario? (Choose two.)
A. VLAN IDs defined on CE interfaces must be the same on both ends unless otherwise negotiated.
B. CE interfaces facing the service provider must be Layer 3 interfaces.
C. CE interfaces facing the service prowler must be Ethernet interfaces.
D. PE interfaces facing the core must have VPLS encapsulation enabled.
正解：A,C

質問 7：
The network team will be performing maintenance on R3. The maintenance window requires a reboot of router R3. You want to gracefully move traffic away from R3 until after the reboot. In this scenario, how would you solve this problem?
A. Configure the set protocols isis interface all level 1 hello-interval 300 parameter, then reboot the router.
B. Configure the set protocols isis interface all level 1 hold-time 300 parameter, then reboot the router.
C. Configure the set protocols isis overload parameter, then commit the configuration.
D. Configure the set protocols isis spf-options delay 300 parameter, then reboot the router.
正解：C
