第2题：

While performing a site survey to document the existing environment before implementing a new HACMP cluster， it was discovered that a port filtering firewall was being used to protect the production system. The plan is to continue using the firewall and add a second firewall to avoid a single point of failure. Each node in the two-node cluster will have all of its network adapters connected to the firewalls， and all connections to the nodes will pass through these firewalls.  What must be considered about HACMP in a firewall environment？（）  

• A、 Firewalls are not supported in a HACMP environment.
• B、 HACMP uses only TCP/IP so firewalls are not relevant.
• C、 Specific ports must be open for HACMP communications.
• D、 Dynamic routing must be used to properly route packets in a firewall-protected environment.

第3题：

Continuous availability is required for an application in a two-node cluster. There is one rotating resource group in the cluster， and the nodes are identical machines. Client telnet connections to the application cannot be broken because it takes 20 to 30 minutes to recycle the client workstations and transactions will be lost.  What configuration best provides continuous connectivity to the application？（）   

• A、 IPAT using IP Replacement without MAC address takeover.
• B、 IPAT using IP Aliasing and hardware MAC address takeover.
• C、 None because continuous telnet connectivity cannot be provided with HACMP.
• D、 Shared service IP address assigned to multiple network interface cards on each node.

第4题：

Company.com is adding HACMP to an existing pair of nodes. One node is using EtherChannel  with only one adapter. The other node is using regular Ethernet connection to the switch. The customer is going to increase the number of network interfaces to two for each node.  What other considerations need to be addressed in a HACMP environment？（）  

• A、 Al interfaces used for HACMP heartbeats must be identical. Differences in the interfaces will cause heartbeat failure.
• B、 The network interfaces should all be configured with the same frame type. The use of regular Ethernet frames is mandatory.
• C、 Network interfaces for HACMP must be all the same，Ethernet or 802.3. It does not matter which，as long as they are all the same.
• D、 HACMP can use any network interface supported by AIX. The options on the various interfaces are masked by the Ethernet switch and do not affect HACMP.

第9题：

Company.com has installed HACMP and is configuring a three-node cluster. One of the Applications  uses the AIX hostname as a key for authorization to execute on the specific computer. The application vendor was contacted and consented to having multiple copies of the application but required that only one application be active at any one point in time.  How can the AIX host name dependency be managed in an HACMP environment.（）  

• A、 It cannot be managed because the application will not work properly with HACMP.
• B、 The application start and stop script for the application can manage the hostname.
