Oracle 1Z0-820 Exam - Cheat-Test.com

Free 1Z0-820 Sample Questions:

Q: 1
Identify the two security features incorporated in the Oracle Solaris 11 Cryptographic Framework.
A. Layer 5 IP address encryptions
B. Internet protocol security
C. Diffie-Kerberos coaxial key encryption
D. Signed cryptographic plugins (providers)
E. Kernel support for signed antivirus plugins
Answer: D,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.
Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.
* 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.

Q: 2
You are configuring NFS on a server. Select the two statements that are true.
A. Resources listed in /etc/dfs/dfstab are automatically shared on boot up.
B. A directory cannot be shared if a subdirectory below it is already shared.
C. Renaming a share created with the zfs set share command is not supported.
D. NFS and SMB protocols cannot be used simultaneously to share the same directory.
Answer: A,C
Explanation: A: ZFS can automatically share file systems by setting the sharenfs property. Using this property, you do not have to modify the /etc/dfs/dfstab file when a new file system is shared.
The sharenfs property is a comma-separated list of options to pass to the share command. The value on is an alias for the default share options, which provides read/write permissions to anyone.
The value off indicates that the file system is not managed by ZFS and can be shared through traditional means, such as the /etc/dfs/dfstab file. All file systems whose sharenfs property is not off are shared during boot.

Q: 3
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__________.
A. An ether stub
B. A virtual router
C. A virtual switch
D. A virtual bridge.
E. A virtual network interface
F. Nothing because a virtual switch is automatically created then the virtual network interfaces are created.
Answer: A
Explanation: 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

Q: 4
You have set up the task.max-lwps resource control on your Solaris 11 system.
Which option describes how to configure the system so that syslogd notifies you when the resources control threshold value for the task.max-lwps resource has been exceeded?
A. Use the rctladm command to enable the global action on the task.max-lwpa resource control.
B. Modify the /etc/syslog.conf file to activate system logging of all violations of task.max-lwps and then refresh then svc: /system/system-log:default service.
C. Activate system logging of all violations of task.max-lwpp in the /etc/rctldm.conf file and then execute the rctladm-u command.
D. Use the prct1 command to set the logging of all resource control violations at the time the task.max-lwps resource control is being setup.
E. Use the setrct1 command to set the logging of all resource control violations for the task.maxlwps resource control.
Answer: A
Explanation: rctladm - display and/or modify global state of system
resource controls
The following command activates system logging of all violations
of task.max-lwps.
# rctladm -e syslog task.max-lwps
#
Reference: man rctladm

Q: 5
You want to deploy oracle Solaris 11 with the automated installer (AI). You need to make sure that your server and network meet the requirements for using AI.
Choose the three options that describe; the requirements for using AI.
A. You can create only one manifest per install service. If you need more than one manifest, create multiple install services.
B. If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS, then create two AI manifests and a single Install service.
C. You need a separate install service for each different client architecture that you plan to install, and for each different version of the Oracle Solaris 11 OS that you plan to install on client systems.
D. If two client machines have different architectures and need to be installed with different versions of the Oracle Solaris 11 OS, then create two AI manifests and two install services.
E. The install server needs to be able to access an Oracle Solaris Image Packaging System (IPS) software package repository; the clients do not.
F. The install server can be either an x86 machine or a SPARC machine.
Answer: B,E,F
Explanation: B:
Note: You can create custom AI manifests for particular clients.
Create a custom XML AI manifest file. This method is best suited to an environment where few systems require custom provisioning. Most systems to be installed have identical or similar hardware and will be provisioned identically.
Write a script that dynamically creates an AI manifest for each client at installation time. Use this method to create a custom installation for each client, based on client characteristics discovered at installation time.
E: AI Server Software Requirements include Software package repository
Ensure that the install server can access an IPS software package repository. AI requires the install/installadm package.
F: Install Server Requirements
Any system that meets these requirements can be used as an AI install server, including laptops, desktops, virtual machines, and enterprise servers. The install server can be either an x86 machine or a SPARC machine. An x86 install server can install both SPARC and x86 clients, and a SPARC install server can install both SPARC and x86 clients.
Note: To install clients over the network, AI requires a separate system to be an install server. On the install server, create an AI install service to provide a net image and instructions for installing the Oracle Solaris 11 OS on different clients.

Q: 6
Which three options are valid methods of installing a Solaris 10 branded zone on a system running Oracle Solaris 11?
A. Use the V2V process to migrate an existing Solaris 8 or9non-global zone from a Solaris 10 system to a solaris10 branded zone.
B. Use the V2V process to migrate an existing Solaris 10 non global whole root zone from a Solaris 10 system to a solaris10 branded whole root zone.
C. Install a solaris10 branded zone directly from the Oracle Solaris 10 media.
D. Migrate an existing 64-bit Solaris 10 system to a solaris10 branded non-global zone using the P2Vprocess.
E. Migrate an existing 32 bit Solaris10 system to a solaris10 branded non-global zone using the P2V process.
F. Use the V2V process to migrate an existing Solaris 10 non-global sparse root zone from a Solaris 10 system to a solaris10 branded sparse root zone.
Answer: B,D,E
Explanation: B: Due to change in package system (SRV4 to IPS) there is no direct upgrade from S10 to S11 one can use
* P2Vconverting s10 physical system to solaris10 branded zone in s11 (32-bit or 64-bit)
* V2V converting s10 native full root zone to solaris10 branded zone in s11 (B)

Q: 7
Which command should you choose to display the current parameters for the FSS scheduler?
A. dispadmin - c FSS
B. prionctl-c FSS
C. dispadmin -c FSS -g
D. priocntl-c FSS -g
Answer: C
Explanation: The dispadmin command displays or changes process scheduler parameters while
the system is running.
-c class
Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fairshare class, and FX for the fixed-priority class. The time-sharing and inter-active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.
-g
Gets the parameters for the specified class and writes them to the standard output.
