Question #6
What three items are true with regard to network planning in a Solaris 11 environment?
- AHardware and network topology should be planned in advance of installation.
- BSubnetting needs to be considered when implementing IPv6 networks.
- CIPv4 and IPv6 network addressing cannot co-exist on the same server.
- DSolaris 11 enables the use of local files, NIS, DNS, or LDAP for name services.
- EThe physical network topology will determine if you need routers, not all networks require routers.
Correct Answer:
ACD
The following table lists different tasks for planning the network configuration.
* (A) Identify the hardware requirements of your planned network topology.
Determine the types of equipment that you need for your network site.
*(C) Determine the type of IP addresses to use and obtain registered IP addresses.
Select whether you are deploying a purely IPv4 network, an IPv6 network, or a network that uses both types of IP addresses. Obtain unique IP addresses to communicate to public networks in the Internet.
* (D) Determine a naming scheme to identify the hosts in the network as well as the name service to use.
Create a list of names to assign to the systems on the network and decide whether to use NIS, LDAP, DNS, or the network databases in the local /etc directory.
* If necessary, establish administrative subdivisions and design a strategy for subnets.
Decide if your site requires that you divide your network into subnets to service administrative subdivisions
* Determine where to place routers in the network design.
If your network is large enough to require routers, create a network topology that supports them.
* Decide whether to create virtual networks in the overall network configuration scheme.
You might need to create virtual networks within a system to reduce the hardware footprint of your network.

Question #7
To upgrade a system from Oracle Solaris 10 to Oracle Solaris 11, it is necessary to________.
- Aconvert all Oracle Solaris 10 packages to Oracle Solaris 11 packages using IPS
- Buse IPS and Live Upgrade to install all updated software
- Cuse IPS to replace the Oracle Solaris 10 kernel with the Oracle Solaris 11 kernel
- Dsave user data and perform a new Oracle Solaris 11 install; there is no upgrade method
- Eupdate Oracle Solaris 10 from an Oracle Solaris 11 repository
Correct Answer:
D
There are no upgrade methods or tools available to transition from Oracle Solaris 10 to Oracle Solaris 11. You cannot use an installer to upgrade from Oracle
Solaris 10 to Oracle Solaris 11.
Oracle Solaris 11 Transition Tools and Features

Solaris 10 to Oracle Solaris 11.
/ JumpStart Migration Utility (js2ai)
Used to convert Oracle Solaris 10 JumpStart rules and profiles to a format that is compatible with AI manifest entries.
/ ZFS shadow migration feature
Used to migrate data from an existing file system to a new file system.
/ Oracle Solaris 11 support for Oracle Solaris 10 zones
Used to migrate your Oracle Solaris 10 application environments to an Oracle Solaris 11 system.
/ NFS file sharing and pool migration
Used to access shared files from an Oracle Solaris 10 system on an Oracle Solaris 11 system.
Used to import a ZFS storage pool from an Oracle Solaris 10 system into an Oracle Solaris 11 system.

Question #8
When attempting to perform an installation of Oracle Solaris 11, you encounter a failure message along the lines of "no offers were received." What is the most likely reason for this message and why?
- AThe system could not obtain a DHCP-based lease so it could not proceed.
- BThe amount of disk space offered by the installer is inadequate so the installer attempted to compress data in memory.
- CThe minimum amount of memory is not sufficient to load the necessary network driver so the installer tried to offer disk as backing store.
- DAn IP address provided is located on a different network segment because the correct RARP server did not respond.
- EThe IP address provided is outside the range of allocatable addresses.
Correct Answer:
A
No DHCP or Proxy DHCP Offers Were Received
If a DHCP server is not responding to an x86 client's request, you see the following messages:
Intel(R) Boot Agent PXE Base Code (PXE-2.1 build 0.86)
Copyright(C) 1997-2007, Intel Corporation
CLIENT MAC ADDR 00 14 4F 29 04 12 GUID FF2000008 FFFF FFFF FFFF 7BDA264F1400
DHCP......... No DHCP or ProxyDHCP offers were received
PXE-MOF: Exiting Intel Boot Agent
The timeout message indicates that the client is sending a DHCP request and not getting a response. This issue is probably due to an error in the DHCP configuration. Check to see if your client is configured correctly in the DHCP server.

Question #10
Which two actions must be taken to enable IP forwarding on all interfaces yet disable on a specific interface?
- Arouteadm –r
- Bipadm set–addrprop
- Cipadm set–ifprop
- Drouteam –e
- Edladm set–router
Correct Answer:
AE
The routeadm command is used to administer system-wide configuration for IP forwarding and routing. IP forwarding is the passing of IP packets from one network to another; IP routing is the use of a routing protocol to determine routes.
-e option...
Enable the specified option. The effect is to prepare the associated services (svc:/network/ipv4-forwarding:default in the case of ipv4-forwarding) for enabling. By means of the routing-svcs variable, the routing daemons are specified to be enabled on subsequent boot or when routeadm -u is run.
-d option...
Disable the specified option. The effect is to prepare the associated services (svc:/network/ipv4-forwarding:default in the case of ipv4-forwarding) for enabling. By means of the routing-svcs variable, the routing daemons are specified to be disabled on subsequent boot or when routeadm -u is run.
