What should be done to ensure the serial network will function with HACMP heartbeats？（）

A. Use either s1 or s2 port configured as a TTY interface with a NULL Modem cable.
B. Use the s2 serial port on each system configured as a TTY interface with a NULL modem cable.
C. Use the s1 port on each system configured as a TTY interface with a standard serial modemcable.
D. Verify with IBM support which native serial ports for the server model can be used for HACM pheartbeats.

单项选择题The administration staff of a large computer complex is resisting the installation of HACMP. There Are concerns about the difficulty of managing and administering an HACMP cluster without an administration only network. Adding adapters to create an administration network is not possible due to limitations on the number of open IO slots in the servers. What can be done to address this issue？（）

A. Create HACMP persistent IP labels for administration purposes.
B. Use HWAT to ensure the correct MAC address is available at all times.
C. Nothing can be done because RPAT is a characteristic of HACMP that cannot be changed.
D. Use IP aliasing within HACMP to allow the administrators constant access to the nodes.

单项选择题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

单项选择题During Company.com planning session， the LVM requirements for HACMP are provided. The administrator explains that there are five volume groups in the current production environment because filesystems constantly change due to the nature of the business. Maintenance outages are limited to one Saturday per month. There is some concern about the amount of time that will be required for outages once HACMP is installed. With HACMP，what will be the simplest methods of managing LVM changes while minimizing required downtime.（）

A. Make changes and allows Lazy Update to sync the changes later.
B. Use the Cluster Single Point Of Control to manage LVM changes.
C. Use exportvg on the primary node and improtvg on the second node.
D. Set up a local NFS cross-mount， and use the local filesystem until the outage.

单项选择题During Company.com planning session， the discussion focuses on how the IP connections are Managed after a cluster node failure.

What type of IPAT implementation would best address these requirements？（）

A. IPAT via IP aliasing
B. IPAT via IP replacement
C. IPAT via IP aliasing using HWAT
D. IPAT via IP replacement using HWAT
