Click the Exhibit button.
There is an existing chassis cluster connected to the corporate network 192.168.1.0/24. You are asked to connect another department to this VLAN. To achieve this, you add a new chassis cluster to the network. After connecting to the network, the cluster experiences traffic problems. You have verified that the addresses and VLAN IDs are configured correctly.
Referring to the exhibit, which configuration would resolve this problem?

問題 2

You want to allow remote users using PCs running Windows 7 to access the network using an IPsec VPN. You implement a route-based hub-and-spoke VPN; however, users report that they are not able to access the network.
What is causing this problem?
