NEW QUESTION # 27
When configuring an LPAR profile, what is the meaning of CPU Entitlement?
- A. the count of virtual CPUs configured on an LPAR
- B. Simultaneous Multi Threading setting of an LPAR
- C. the amount of guaranteed CPU time allocated to an LPAR
- D. the number of logical CPUs allocated to an LPAR
Answer: C
Explanation:
CPU Entitlement is a setting in the LPAR profile that defines the amount of guaranteed CPU time allocated to an LPAR. This setting is important for workloads that require a steady level of performance, as it guarantees that the LPAR will always have access to a certain percentage of the processing power on the managed system. Reference: IBM AIX v7 Administrator Specialty Study Guide.
CPU Entitlement in AIX refers to the guaranteed amount of CPU time that is allocated to a logical partition (LPAR). It ensures that the LPAR receives a specific share of the processor resources, regardless of the load on the system. This setting is crucial for ensuring that critical applications have the necessary CPU resources to perform optimally. It is different from the total number of virtual CPUs configured, as it represents a minimum guarantee rather than the maximum potential CPU usage.References: IBM AIX Documentation - CPU Entitlement
NEW QUESTION # 28
What impact does an EtherChannel network device have on network flow?
- A. Each network adapter port added to the channel doubles the speed of the flow.
- B. TCP traffic may be held up to allow UDP traffic to run faster.
- C. All network flow is converted to jumbo frames.
- D. Traffic will flow through other available adapters if one fails.
Answer: D
Explanation:
An EtherChannel network device provides network redundancy and load balancing by combining multiple physical network adapters into a single logical interface. If one adapter fails, traffic will automatically flow through the other available adapters in the channel, ensuring continuous network availability.References:= IBM AIX EtherChannel Documentation
NEW QUESTION # 29
A system administrator has noticed that static routes are missing after rebooting a system. What is the most likely reason for this?
- A. The administrator has failed to run the cfgmgr command before rebooting the systems.
- B. The administrator has failed to configure the routes in the inet0 device with the chdev command.
- C. The administrator has failed to configure the routes with the route add command.
- D. The administrator has failed to configure the routes in the lo0 device with the chdev command.
Answer: A
Explanation:
The administrator has failed to run the cfgmgr command before rebooting the systems. Running the cfgmgr command before rebooting a system is important, as it ensures that any changes made to the configuration are written to the system, otherwise the changes may be lost when the system is rebooted. Other commands such as chdev and route add are not related to this issue and will not solve the problem.
For more information on the cfgmgr command, please refer to the IBM AIX v7 Administrator Specialty Study Guide, page 10-7. The guide can be found here: https://www.ibm.com/support/knowledgecenter/en/ssw_aix_72/cfgmgmt/cfgmgr_command.htm.

NEW QUESTION # 40
Which user account is always UID 0 on AIX?
- A. root
- B. bin
- C. system
- D. admin
Answer: A
Explanation:
The root account is the special user in the /etc/passwd file with the user ID (UID) of 0 and is commonly given the user name, root. It is not the user name that makes the root account so special, but the UID value of 0. This means that any user that has a UID of 0 also has the same privileges as the root user. Also, the root account is always authenticated by means of the local security files.
