NEW QUESTION # 56
Which three of the components could be used in a ZFS storage pool, but are not recommended configurations?

A. A LUN In a hardware RAID array
B. A Solaris Volume Manager (SVM) volume
C. A file on a UFS file system
D. A disk slice from an SMI labeled disk
E. A Veritas Volume Manager (VxVM) volume
F. An EFI labeled disk

Answer: B,C,E

Explanation:
A: ZFS also allows you to use UFS files as virtual devices in your storage pool. This feature is aimed primarily at testing and enabling simple experimentation,not for production use. The reason is that any use of files relies on the underlying file system for consistency. If you create a ZFS pool backed by files on a UFS file system,then you are implicitly relying on UFS to guarantee correctness and synchronous semantics. However,files can be quite useful when you are first trying out ZFS or experimenting with more complicated layouts when not enough physical devices are present. All files must be specified as complete paths and must be at least 64 Mbytes in size.
B,E: You can construct logical devices for ZFS using volumes presented by software-based volume managers,such as Solaris Volume Manager (SVM) or Veritas Volume Manager (VxVM). However,these configurations are not recommended. While ZFS functions properly on such devices,less-than-optimal performance might be the result.

NEW QUESTION # 57
You log in to the system as user1, then switch user to root by using the su - command. After entering the correct password, yon enter the following commands:
whoami;who am i;id
Which option correctly represents the output?

A. Option B
B. Option C
C. Option D
D. Option A

Answer: A

Explanation:
* The whoami utility displays your effective user ID as a name.
Here this would be root.
* who am i
The command who shows who is logged on.
Here this would be:
user1 console Dec 30 20:20
* The id utility displays the user and group names and numeric IDs, of the calling process, to the standard output. If the real and effective IDs are different, both are displayed, otherwise only the real ID is displayed.
Here this would be:
uid=0(root) gid=0(root)
Note:
Each UNIX proces has 3 UIDs associated to it. Superuser privilege is UID=0.
Real UID
--------
This is the UID of the user/process that created THIS process. It can be changed only if the running process has EUID=0.
Effective UID
-------------
This UID is used to evaluate privileges of the process to perform a particular action. EUID can be change either to RUID, or SUID if EUID!=0. If EUID=0, it can be changed to anything.
Saved UID
---------
If the binary image file, that was launched has a Set-UID bit on, SUID will be the UID of the owner of the file.
Otherwise, SUID will be the RUID.

NEW QUESTION # 61
Your server has a ZFS storage pool that is configured as follows:

The server has two spate 140-GB disk drives: c3t5d0 c3t6d0
Which command would add redundancy to the pool1 storage pool?

A. zpool attach pool1 c3t5d0 c3t6d0
B. zpool add raidz pool1 c3t5d0 c3t6d0
C. zpool mirror pool1 c3t5d0 c3t6d0
D. zpool attach pool1 c3t3d0 c3c5d0; zpoo1 attach pool1 c3t4d0 c3t6d0
E. zpool add pool1 mirror c3t5d0 c3t6d0

Answer: A

Explanation:
You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
Note: zpool attach [-f] pool device new_device Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

NEW QUESTION # 64
You have been asked to do an orderly shutdown on a process with a PID of 1234,with the kill command.
Which command is best?

A. kill -1 1234
B. kill -15 1234
C. kill -9 1234
D. kill -2 1234

Answer: B

Explanation:
On POSIX-compliant platforms,SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms,however on the vast majority of systems,SIGTERM is signal #15.
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process,but unlike the SIGKILL signal,it can be caught and interpreted (or ignored) by the process. Therefore,SIGTERM is akin to asking a process to terminate nicely,allowing cleanup and closure of files. For this reason,on many Unix systems during shutdown,init issues SIGTERM to all processes that are not essential to powering off,waits a few seconds,and then issues SIGKILL to forcibly terminate any such processes that remain.

NEW QUESTION # 65
A datalink can best be described as______.

A. the software connecting the Internet Layer and the Physical Layer
B. a device that provides Classless Inter-Domain Routing
C. a driver for a Network Interface Card
D. a logical object used for IP Multipathing

Answer: D

Explanation:
The command dladm is used to configure data-link interfaces in Sun Solaris. A configured data-link is represented in the system as interface that can be used for TCP/IP. Each data-link relies on either a single network device or an link aggregation device to send & recieve packets.
Network interfaces provide the connection between the system and the network. These interfaces are configured over data links, which in turn correspond to instances of hardware devices in the system.
In the current model of the network stack, interfaces and links on the software layer build on the devices in the hardware layer. More specifically, a hardware device instance in the hardware layer has a corresponding link on the data-link layer and a configured interface on the interface layer. This one-to-one relationship among the network device, its data link, and the IP interface is illustrated in the figure that follows.

NEW QUESTION # 66
Review the storage pool information:

Which statement describes the status of this storage pool?

A. It is an improperly configured RAIDZ storage pool; data will be striped across three disk components, but only three drives are protected with redundancy.
B. It is a double-parity RAIDZ storage pool and can withstand two disk failures; data will be striped across four disk components.
C. It is a RAIDZ storage pool and can withstand a single disk failure; data will be striped at: disk components.
D. It is an improperly configured RAIDZ storage pool; data will be striped across four disk components, but only three drives are protected with redundancy.

Answer: A

Explanation:
Explanation/Reference:
Explanation:
Device c3t6d0 is not included in the RAIDZ storage pool. The other three devices are included in the raidz pool. The data on these devices are protected.
Note: In addition to a mirrored storage pool configuration, ZFS provides a RAID-Z configuration with either single, double, or triple parity fault tolerance. Single-parity RAID-Z (raidz or raidz1) is similar to RAID-5.
Double-parity RAID-Z (raidz2) is similar to RAID-6.

NEW QUESTION # 67
Identify the two security features incorporated in the Oracle Solaris 11 Cryptographic Framework.

A. Diffie-Kerberos coaxial key encryption
B. Internet protocol security
C. Kernel support for signed antivirus plugins
D. Layer 5 IP address encryptions
E. Signed cryptographic plugins (providers)

Answer: C,E

Explanation:
The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another name for providers is plugins. The framework allows three types of plugins:
*User-level plugins - Shared objects that provide services by using PKCS #11 libraries, such as pkcs11_softtoken.so.1.
*Kernel-level plugins - Kernel modules that provide implementations of cryptographic algorithms in software, such as AES.
*Hardware plugins - Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardware accelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example.
Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.

NEW QUESTION # 68
When issuing the zonestat 2 1h is command, the following information is displayed: Which two options accurately describe the statistics contained in the output?

A. dbzone is using 2.37% of the global zone's total virtual memory.
B. dbzone is using 0.21% of the global zone's total CPU.
C. The network is being utilized 100% with no physical bandwidth remaining.
D. dbzone is using 0.21% of the total CPU resource available in the zone's processor set.
E. dbzone is using 5.48% of the total physical memory that has been allocated to the zone.

Answer: D,E

Explanation:
A: %PART The amount of cpu used as a percentage of the total cpu in a processor-set to which the zone is bound. A zone can only have processes bound to multiple processor sets if it is the global zone, or if psrset(1m) psets are used. If multiple binding are found for a zone, it's %PART is the fraction used of all bound psets. For [total] and [system], %PART is the percent used of all cpus on the system.
Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the zone's configured limits.
The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval.

Explanation:
You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
Note: zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

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?

A. echo 192.168.1.1 >/etc/defaultrouter
B. route add default 192.168.1.1
C. ipadm set-gateway 192.168.1.1
D. ipadm set-default 192.168.1.1
E. echo 192.168.1.1>/etc/gateway
F. dladm route-add -d 192.168.1.1

Answer: A,B

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
