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.

An HACMP cluster has three nodes of unequal size. The largest node is Node ’A’. The primary application on Node ’A’ has two components. One component is memory intensive， the other is IO intensive. Nodes ’B’ and ’C’ are running web servers and databases that access information produced by applications on Node ’A’. The customer requires the most performance from the primary application and wants all nodes available for fallover processing.
Which of the following is the best solution for meeting the customer requirements？（）

A. Use nodes of equal size.
B. Create multiple resource groups and use loadlever.
C. Use dynamic node priority to manage resource groups.
D. Use an ordered list to manage resource group fallover.

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.
