Question 133

You have completed configuring a zone named dbzone on your Solaris 11 server. The configuration is as following:

The global zone displays the following network information:

The zone has never been booted. Which three options correctly describe this zone?

Correct Answer: C,E,G
Explanation/Reference:
Explanation:
C: Immutable Zones provide read-only file system profiles for solaris non-global zones.
Note that ip-type: exclusive:
Starting with OpenSolaris build 37 and Oracle Solaris 10 8/07, a default zone can be configured as an
"exclusive-IP zone" which gives it exclusive access to the NIC(s) that the zone has been assigned.
Applications in such a zone can communicate directly with the NIC(s) available to the zone.
Note on zones:
After installing Oracle Solaris on a system, but before creating any zones, all processes run in the global zone. After you create a zone, it has processes that are associated with that zone and no other zone. Any process created by a process in a non-global zone is also associated with that non-global zone.
Any zone which is not the global zone is called a non-global zone. Most people call non-global zones simply "zones." Some people call them "local zones" but this is discouraged.
The default native zone file system model on Oracle Solaris 10 is called "sparse-root." This model emphasizes efficiency and security at the cost of some configuration flexibility. Sparse-root zones optimize physical memory and disk space usage by sharing some directories, like /usr and /lib. Sparse-root zones have their own private file areas for directories like /etc and /var. Whole-root zones increase configuration flexibility but increase resource usage. They do not use shared file systems for /usr, /lib, and a few others.
There is no supported way to convert an existing sparse-root zone to a whole-root zone. Creating a new zone is required.

Question 134

Oracle Solaris 11 kernel encounters a fatal error, and it results in a system panic.
What type of file does this generate?

Correct Answer: C
A kernel panic is a type of error that occurs when the core (kernel) of an operating system receives an instruction in an unexpected format or when it fails to handle properly. A kernel panic can also follow when the operating system can't recover from a different type of error.
A kernel panic can be caused by damaged or incompatible software or, more rarely, damaged or incompatible hardware.
When a server kernel panics it abruptly halts all normal system operations. Usually, a kernel process named panic() outputs an error message to the console and stores debugging information in nonvolitile memory to be written to a crash log file upon restarting the computer. Saving the memory contents of the core and associated debugging information is called a "core dump."

Question 135

You are troubleshooting a newly installed desktop Oracle Solaris 11 system with a single network interface. From this system, you can connect to other systems within the company intranet, but cannot access any external services (such as websites and email), even when using IP addresses.
Examining the routing table confirms that the default route to 192.168.1.1 is missing. DHCP is not used at this site. Which two commands will temporarily mid permanently configure the default route?

Correct Answer: B,F
Explanation/Reference:
Explanation:
B: Setting the default route on Solaris is easy. If you are trying to just set the route temporarily you can use the route command:
Route add default <ipaddress>
Example:
Route add default 192.168.1.1
Note: Route command manipulates the kernel routing tables. Routing is the process of forwarding a packet from one computer to another. It is based on the IP address in the IP packet header and netmask.
F: If you want the route to be persisted when you reboot the system, you will need to set the route in the / etc/defaultrouter file.
/etc/defaultrouter
Example:
Echo 192.168.1.1 > /etc/defaultrouter
