第4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5题：

Which of the following statements is true about IPAT via IP replacement？（）  

• A、 Configuration of Hardware Address Takeover is supported.
• B、 Fewer physical network interface cards are required in the cluster.
• C、 It is the default for keeping a service IP labels highly available.
• D、 None-service ip labels must use different subnets than service IP labels.

第6题：

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？（）   

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

第7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8题：

A database administrator wants a unique IP address for each of three instances of a database.  Normally，all instances run on a large production node，but they may fallover to different standby nodes according to the dynamic node priority configuration.  What is the best way to obtain unique addresses for each of the three database instances？（）

• A、 There is no way since this cannot be configured with HACMP
• B、 Use IP Replacement address takeover and define all service addresses on the same NIC
• C、 Use IP Aliasing for address takeover and define each alias in a separate resource group
• D、 Use EtherChannel to map the three alias IP addresses to the common service address defined to HACMP

第9题：

Company.com with an EtherChannel implementation is considering an HACMP solution. What considerations must be addressed in planning this configuration？（）  

• A、 Hardware address takeover must be configured.
• B、 IPAT via IP aliasing is required for EtherChannel.
• C、 EtherChannel must be defined as a separate network.
• D、 HACMP does not support the fallover of EtherChannel.

第10题：

Company.com has several network adapters configured as backup paths using the Virtual IP Addressing and dynamic routing of AIX. A second node needs to be added to the environment to crate a cluster. What considerations must be addressed during the planning session？（）  

• A、 HACMP supports most types of networks，including Virtual IP Addressing by AIX.
• B、 If HACMP IP aliasing is used，the devices may be the Virtual IP type used by AIX.
• C、 Using the AIX Virtual IP Addressing scheme HACMP can provide near fault tolerant availability of the network.
• D、 The AIX Virtual Addressing mechanism is not supported by HACMP，but a similar configuration can be created in HACMP.
