第4题：

Company.com environment consists of 10 volume groups and 4 physical networks. The customer  Desires the fastest possible fallover for a two-node cluster.  Which of the following configuration alternatives will provide the fastest fallover？（）  

• A、 IPAT via IP Aliasing，default shared volume groups
• B、 IPAT via IP Replacement default shared volume groups
• C、 IPAT via IP Aliasing，enhanced concurrent volume groups

第5题：

A cluster node has three network interfaces that support three resource groups with three service  IP labels. Each IP label uses IPAT via IP aliasing. One of the adapters fails， and all of the IP labels on it are moved to other interfaces as expected. The system supports the "hot swap" replacement of the network interfaces， and the system engineer has corrected the problem.  What will happen to the service IP lab3els when the repaired adapter is noticed by HACMP？（）

• A、 They will migrate back to the repaired interface.
• B、 They will not move，the interface will join the pool of available resources.
• C、 They will not move； the interface will join the cluster as an available non-service adapter. 
• D、 They will migrate to the repaired interface to create an equal number of service IP labels per interface.

第6题：

A cluster with 10 adapters per node is converted to use IPAT address takeover vial IP aliasing.  During the conversion， the customer ran out of IP subnets in the allocated range.  What feature in HACMP can help resolve this issue？（）  

• A、 Disk based heartbeats
• B、 Heart beating via IP aliasing
• C、 IP aliases for the non-service addresses
• D、 A single subnet for all non-standby adapters

第7题：

During Company.com planning session， the network administrator discusses the requirements of having a persistent MAC address associated with the IP Service address.  How can this be accomplished using HACMP？（）  

• A、 Enable routed to handle dynamic route creation.
• B、 Use IPAT via IP aliasing and define the required MAC address.
• C、 Add the Service IP Label to the /etc/cluster/ping_client_list.
• D、 Use IPAT via IP replacement and define the required MAC address.

第8题：

What restrictions apply to using virtual Ethernet within a cluster containing VIO clients？（）

• A、IPAT via Aliasing must be used
• B、IPAT via Replacement must be used
• C、Resilience must be provided by the use of dual VIO servers
• D、Hardware Address Takeover （HWAT） must be used to ensure a consistent virtual MAC address

第9题：

A network for a two-node cluster has been planned. The network administrator has explained that the networkdoes not support gratuitous ARP. Which of the following steps will ensure that clients are able to connect tothe cluster after a failover takes place？（）

• A、Implement heartbeating over IP aliases
• B、Implement persistent service IP addresses
• C、Implement IPAT aliasing with hardware address takeover （HWAT）
• D、Implement IPAT replacement with hardware address takeover （HWAT）

第10题：

Company.com is considering converting from IPAT via replacement to IPAT via IP aliasing. What condition of IPAT via IP aliasing must be taken into consideration？（）

• A、 The clients must support gratuitous ARP.
• B、 The network type must support gratuitous ARP.
• C、 Additional TCP/IP interfaces must be allocated for backup in case of failure.
• D、 Using IPAT via IP aliasing will reduce the number of rotating resource groups that can be used.
