Juniper JN0-682 問題集

質問 1：
You need to add perimeter security to the network shown in the exhibit. All traffic must be inspected for attacks. The edge routers are using all available ports. Your solution must maintain both port and device resiliency.

In this scenario, which design would satisfy these requirements?
A. one-arm SRX Series chassis cluster
B. one-arm SRX Series device using LAG
C. inline SRX Series chassis cluster
D. inline SRX Series device using LAG
正解：C

質問 2：
You are implementing an EVPN overlay in your IP fabric data center. The IP fabric was stable before configuring the overlay group and EVPN-related settings. After committing the configuration shown in the exhibit on your spine device, you are no longer exchanging any routes in your underlay fabric.

In this scenario, what will solve this problem?
A. You must change the overlay group to establish an EBGP peering instead of IBGP.
B. You must move the EVPN NLRI family declaration to be applied under the overlay BGP group.
C. You must remove the multipath parameter from the overlay group.
D. You must remove the export policy applied to your fabric group.
正解：D

質問 3：
You have successfully deployed an IP fabric in your data center. However, your server team complains that they are not seeing an increase in performance as expected. After examining the routing and forwarding tables, you notice that only a single route is listed to each destination in the forwarding table, even though there are multiple routes shown in the routing table.
In this scenario, what should you do to solve the problem?
A. Write a load balancing policy and apply it to the forwarding table.
B. Disable the Spanning Tree Protocol that is blocking the redundant paths.
C. Write a load balancing policy and apply it to the routing table.
D. Modify the hash algorithm so that only source and destination addresses are used.
正解：A

質問 4：
You are deploying your data center switches using ZTP.
A brand new QFX5120 switch has been booted for the first time. It is failing to upgrade to the desired Junos OS version.
In this scenario, which two actions would you take to troubleshoot this problem? (Choose two.)
A. From the configuration mode, issue the load factory-default and commit commands to re-initiate the ZTP request.
B. Ensure that the correct Juniper default FTP password is defined under the DHCP configuration option and restart the FTP service.
C. Log in to the switch through the console and look for log messages that might indicate the cause of the issue.
D. Ensure that anonymous login is enabled on the FTP server and that the FTP service is running.
正解：C,D

質問 7：
You are implementing a second data center and must have some of your VLANs active in both data centers. You must provide high availability, fast reconvergence, and avoid tromboning traffic on these VLANs.
In an over-the-top DCI strategy, which two statements are correct? (Choose two.)
A. The VLAN ID must be the same in both data centers, but the VNI can be different.
B. The VLAN ID and VNI must be the same in both data centers for these VLANs.
C. A type-5 route for each host must be advertised from the data center where the host resides.
D. A single type-5 route for the subnet must be advertised from both data centers.
正解：B,D
