Show Answer

Correct Answer: B

Question No. 2

You display the IP interface information with ipmpstat -i.

Which two characteristics are indicated by characters that may be included in the FLAGS column?

Adefault route

BIP forwarding enabled IS

Callocated to global zone

Dunusable due to being inactive

Enominated to send/receive IPv4 multicast for its IPMP group

Show Answer

Correct Answer: D, E

FLAGS

Indicates the status of each underlying interface, which can be one or any combination of the following:

(D) d indicates that the interface is down and therefore unusable.

(E) M indicates that the interface is designated by the system to send and receive IPv6 multicast traffic for the IPMP group.

Note:

i indicates that the INACTIVE flag is set for the interface. Therefore, the interface is not used to send or receive data traffic.

s indicates that the interface is configured to be a standby interface.

m indicates that the interface is designated by the system to send and receive IPv4 multicast traffic for the IPMP group.

b indicates that the interface is designated by the system to receive broadcast traffic for the IPMP group.

h indicates that the interface shares a duplicate physical hardware address with another interface and has been taken offline. The h flag indicates that the interface is unusable.

Question No. 3

After installing the OS, the following network configuration information is displayed from the system:

Which option describes the state of this server?

AThe automatic network configuration option was chosen during the installation of the OS.

BThe manual network configuration option was chosen during the installation of the OS.

CThe network was not configured during the installation of the OS.

DThe network interface is configured with a static IP address.

Show Answer

Correct Answer: C

Only the loopback addresses are configured. No IP address is configured.

Question No. 4

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__________.

AAn ether stub

BA virtual router

CA virtual switch

DA virtual bridge.

EA virtual network interface

FNothing because a virtual switch is automatically created then the virtual network interfaces are created.

Show Answer

Correct Answer: A

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

Question No. 5

The following image properties are displayed on your system:

Which two options describe the boot environment policy property that is currently set for this image?

AAll package operations are performed in a new BE set as active on the next boot.

BDo not create a new BE . The install, update, uninstall, or revert operation is not performed if a new BE is required.

CIf a BE is created, do not set it as the active BE on the next boot

DA reboot is required for all package operations

EA reboot is not required after a package operation.

FFor package operations that require a reboot, this policy creates a new BE set as active on the next boot.

Show Answer

Correct Answer: D, F

Image properties described below.

* be-policy

Specifies when a boot environment is created during packaging operations. The following values are allowed:

/ default

Apply the default BE creation policy: create-backup.

/ always-new (D, F)

Require a reboot for all package operations (D) by performing them in a new BE set as active on the next boot (F). A backup BE is not created unless explicitly requested.

This policy is the safest, but is more strict than most sites need since no packages can be added without a reboot.
