• A、1
• B、2
• C、3
• D、4

• B、Chassis clusters are used to create aggregate interfaces.
• C、Chassis clusters are used to group two chassis into one logical chassis.
• D、Chassis clusters are used to group all interfaces into one cluster interface.

A customer has two single cluster IBM TS7700 Virtualization Engines at the same site. The customer wants to move one to a remote site and set up a grid configuration with the two clusters. The customer has fibre between the two sites. What is the most important factor to consider when planning the new configuration?（）

• A、operator training
• B、cache size of the two clusters
• C、fibre bandwidth capability between the sites

第10题：

A two-node cluster is configured for mutual takeover with two service IP labels. The cluster is Being tested for fallover behavior. Both nodes in the cluster have two network interfaces （ent0’ and ’ent1’） configured with IPAT via IP Replacement. When the network cable is removed from the interface card with the service address （’ent0’）， the service address is moved to ’ent1’， and ’ent0’ is reconfigured on its boot address. When the network cable is replaced on ’ent0，the service address does not switch back to ’ent0’.  What statement most accurately describes this situation？（）   

• A、 EtherChannel is needed to automatically switch the service IP address back to ’ent0’.
• B、 This is the default behavior for a network interface failure with this configuration.
• C、 Gratuitous ARP support needs to be enabled for the IP Network Interface Module in SMIT.
• D、 The Inactive Network Takeover option should be set to "true" to forece the service address back to ’ent0’.
