Interface ge-0/0/2.0 of your router is attached to the Internet and is configured with an IP address and network mask of 71.33.252.17/24. A host with IP address 10.20.20.1 is running an HTTP service on TCP port 8080. This host isattached to the ge-0/0/0.0 interface of your router. You must use interface-based static NAT to make the HTTP service on the host reachable from the Internet. On which IP address and TCP port can Internet hosts reach the HTTP service?（）A、IP address 10.10.10.1 and TCP port 8080B、IP address 71.33.252.17 and TCP port 80C、IP address 71.33.251.19 and TCP port 80D、IP address 71.33.252.19 and TCP port 8080

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.
考题
A two-node cluster is configured for mutual takeover with two service IP labels. The cluster is Being tested for fallover behavior. Both nodes in the cluster have two network interfaces （ent0’ and ’ent1’） configured with IPAT via IP Replacement. When the network cable is removed from the interface card with the service address （’ent0’）， the service address is moved to ’ent1’， and ’ent0’ is reconfigured on its boot address. When the network cable is replaced on ’ent0，the service address does not switch back to ’ent0’. What statement most accurately describes this situation？（） A、 EtherChannel is needed to automatically switch the service IP address back to ’ent0’.B、 This is the default behavior for a network interface failure with this configuration.C、 Gratuitous ARP support needs to be enabled for the IP Network Interface Module in SMIT.D、 The Inactive Network Takeover option should be set to "true" to forece the service addressback to ’ent0’.
考题
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.
