• B、 HACMP/XD://PPRC
• C、 HACMP/XD://GPFS
• D、 HACMP/XD://HAGEO

第6题：

Company.com has I/O slot constraints on two nodes that are going to be configured in an  HACMP cluster. There is room for only one Network Interface Card in each node，in addition to the built-in Ethernet port on the system planer.  The best HACMP configuration for these servers is to implement：（）  

• A、 A single adapter network using the Network Interface Card in each node
• B、 A single adapter network using persistent addresses on the Network Interface Card in each node
• C、 A dual adapter network using the internal Ethernet adapters as an non-service interface with IPAT via IP Replacement.
• D、 EtherChannel high availability for the network connections with HACMP cascading resource groups for data and application fallover

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.
