During Abc .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
C. Add the Service IP Label to the /etc/cluster/ping_client_list.
D. Use IPAT via IP replacement and define the required
During a planning session, it is determined that both
nodes in a mutual takeover cluster will provide NFS
mounts to a variety of Unix hosts. What is the first
consideration that must b4e taken into account when
using NFS with HACMP?
A. AIX Connections will need to be installed to provide
the NFS shares.
B. Mutual takeover cluster cannot provide NFS services
from both nodes.
C. The major number for the volume groups needs to be
the same on both nodes.
D. The no option rfc 1323 must be set to 1 and the number
of biods need to be adjusted to provide reasonable response
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
A. There is no way since this cannot be configured with
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.
Abc .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
D. The AIX Virtual Addressing mechanism is not supported
by HACMP, but a similar configuration can be created
Abc .com has a new computer room that will be used to
house a new HACMP cluster. Once of the outstanding features
of the new computer room was the new large air conditioner.
This unit has enough excess capacity for more than double
the planned amount of equipment. Another feature of
this computer room was the dual electric supplies to
the room housed in two separate power panels. How would
this impact the overall availability of the environment?
A. Dual power feeds will make the installation difficult
to manage and less high available.
B. The single air conditioner is a single point of failure
and the customer should be made aware of the issue.
C. The single air conditioner is a single point of failure
and HACMP should be customized to compensate for the
D. A single power feed should be used to avoid ground
loops in the computer room causing premature failure
of the systems.
Abc .com has an application that requires a serial connection
for Electronic Data Interchange. What must be done to
integrator the serial connection into an HACMP cluster?
A. Use an RS3232/422 serial Y cable.
B. Alter the device settings to 9600 8/n/1 xon/xoff.
C. Use a network based terminal server for the serial
D. Nothing because HACMP does not support native serial
During a planning session, Abc .com expresses concern
about the behavior of the nodes when HACMP is installed.
Once department is reliant on an older piece of equipment
that is critical to operations and must communicate
to the database server. Previous network changes indicated
that this piece of equipment does not support gratuitous
ARP. How can HACMP best incorporate this restriction
into the cluster design?
A. The administrator must use Hardware Address Take
over with HACMP.
B. The clsmuxpd process and the contents of the /etc/cluster/ping_client_list
can address the issue.
C. HACMP does not have any facility to be compatible
with older devices that have limited capabilities.
D. HACMP can use either hardware address take over,
or clinfo can update the arp cache of the clients when
an adapter event occurs.
An enterprise has three nodes: -Node 'A' is a production
database, -Node 'B' is a production application server,
and -Node 'C' is a test and development node. Node 'C'
is used by six programmers to develop and the production
application as business critical and would like to make
it highly available with HACMP. Application development
and testing is not business critical. Which of the following
describes the best solution?
A. There is not an adequate solution because HACMP should
not be configured in this environment without a dedicated
B. Nodes 'A' and 'B' should be configured in a cluster
with mutual fallover of two cascading resource groups
to provide both nodes will deliver acceptable response
time with both resource groups.
C. Nodes 'A' and 'C' should be configured in one cluster,
and Nodes 'B' and 'C' in another cluster to prevent
both the database and application server from falling
over to Node 'C' at the same time.
D. Nodes 'A', 'B', and 'C' should be configured in a
cluster with Node 'C' the hot standby for both the database
and application server resource groups. Workload Manager
(WLM) must be configured on database and application
developers from over utilizing the CPU resources.
Abc .com wishes to use IPAT via IP replacement in a
two-node mutual cluster. Each node has two Ethernet
10/100/1000 adapters. Throughout the planning session,
the customer has asked questions about subnet and VLAN
requirements for the intended network topology. Which
of the following best describes the network requirements?
A. The service IP addresses must be on a separate subnet
B. The non-service and service IP addresses must be
on the same subnet and on the same VLAN.
C. All interfaces on a node must be in different subnets.
All subnets must be on the same VLAN.
D. One non-service and one service IP address must be
on the same logical subnet. All interfaces must be on
the same VLAN.
