1z0-820 Upgrade to Oracle Solaris 11 System Administrator - Practice Questions

Question 7

The rctladm command reports the following:

# rctladm |grep task.max.lwps task.max-lwps syslog=notice [ count ]

Which of the following correctly describes the system configuration?

Select an option, then click Submit answer.

○
A message will be logged with syslogd when the number of notice messages generated by the resource control threshold meets or exceeds the value specified with [count].
○
A message will be logged with sysloqd when the number of violations generated by the resource control threshold meets or exceeds the value specified with [count].
○
The global resource control monitoring for the task.max-lwps resource control has been enabled and syslog messaging for that resource control has been set to notice. However, because the [count] value has not been specified, there is no threshold set for the resource to monitor. The configuration to monitor the task.max-lwps resource control is incomplete.
○
The global resource control monitoring for the task.max-lwps resource control has been enabled. syslog messaging for that resource control has been set to notice.

Question 8

View the Exhibit, a file named testzone.cfg:

Select the command that will use the information in this file to create a new zone named testzone2.

Select an option, then click Submit answer.

○
zonecfg -z testzone2 < testzone.cfg
○
zonecfg -z testzone2 import testzone.cfg
○
zoneadm -z testzone2 clone testzone.cfg
○
zonecfg -z testzone2 -f testzone.cfg

Question 9

You have been tasked with creating a dedicated virtual network between two local zones within a single system. In order to isolate the network traffic from other zones on that system.

To accomplish this, you will create__________.

Select an option, then click Submit answer.

○
An ether stub
○
A virtual router
○
A virtual switch
○
A virtual bridge.
○
A virtual network interface
○
Nothing because a virtual switch is automatically created then the virtual network interfaces are created.

Reference / correct answer:

An ether stub

Etherstubs are pseudo ethernet NICs which are managed by the system administrator. You can create VNICs over etherstubs instead of over physical links. VNICs over an etherstub become independent of the physical NICs in the system. With etherstubs, you can construct a private virtual network that is isolated both from the other virtual networks in the system and from the external network. For example, you want to create a network environment whose access is limited only to your company developers than to the network at large. Etherstubs can be used to create such an environment.

Note: Oracle Solaris 11 introduces a new and powerful network stack architecture which includes:

* Networking virtualization with virtual network interface cards (VNICs) and virtual switching(etherstubs)

* Tight integration with zones

* Network resource management - efficient and easy to manage integrated quality of service(QoS) to enforce bandwidth limit on VNICs and traffic flows We will be examini
