The IP subsystem fallover behavior of a two-node cluster is being testing in a large client organization. One of the tests is to simulate a network_down event and verify that HACMP movesthe single resource group to the standby node. What is the best way to simulate a network down condition？（）

A. Turn off the IP core switch connecting the two nodes.
B. Issue the command "stopsrc -g inetd" on the node that has the resource group.
C. Issue the command "sh /etc/rc.tcpclean" on the node that has the resource group.
D. Simultaneously unplug all network cables from the node that has the resource group.

To enhance the availability of an application running under HACMP， a decision was made to use The application monitoring facility. The application consists of several components and can take several minutes to initialize. The components use socket communication and can be initialized in any order as long as it is a serial order. The customer’s concern is that if the application stop and start scripts are used during application monitoring recovery，it may take an extraordinary length of time to reset all of the application components. What can be done to ensure the best recover time？（）

A. Use a process monitor that restarts the named processes in the original start order.
B. Use the defined application start and stop scripts to control the application if there is a failure.
C. Use multiple application monitors for this resource group to enable the monitoring of the specific components of the resource group.
D. Use application cleanup and restart scripts designed to determine the state of the various components of the application and start only the parts required.

During a planning session， the customer indicates that they intend to build two independent two- Node clusters （cluster ’A’ and ’B’） that will be provided shared storage form an IBM TotalStorage FAStT900 server. The customer intends to present 2 LUNs to cluster ’A’， and 2 LUNs to cluster ’B’. All hosts will be dual attached via fibre. What additional hardware or software is necessary to make this a valid configuration？（）

A. SAN switches
B. Fibre channel Hub（s）
C. IBM Storage Manager Agents
D. IBM Subsystem Device Driver

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 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

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.

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.
Dynamic routing must be used to properly route packets in a firewall-protected environment.

Company.com is planning for an HACMP cluster and wants to know more about the network requirements. The plan is to use IPAT via IP aliasing and heartbeating via IP aliasing to preserve the corporate IP addresses. Currently the customer uses a separate VLAN for each individual subnet. Which statement best describes how HACMP co-exists with VLAN’s in this configuration？（）

All subnets in use by HACMP must be in the same VLA
B. All subnets in sue by HACMP must be in a different VLA
C. HACMP does not support multiple subnets when using heartbeating via IP aliasing.
D. HACMP does not support the use of VLA
