NEW QUESTION 4
Which two options accurately describe the network characteristics of a zone?
- A. DHCP address assignment cannot be configured in a shared IP zone.
- B. Shared IP is the default type of network configuration.
- C. Exclusive IP is the default type of network configuration.
- D. By default, all IP addresses, netmasks, and routes are set by the global zone and cannot be altered in a non global zone.
- E. IPMP cannot be managed within the non-global zone.
- F. Commands such as snoop and dladm cannot be used on datalinks that are in use by a running zone.
A: Non-global zones can not utilize DHCP (neither client nor server).
B (not C): By default, non-global zones will be configured with a shared IP functionality. What this means is that IP layer configuration and state is shared between the zone you’re creating and the global zone. This usually implies both zones being on the same IP subnet for each given NIC.
Note: A zone is a virtual operating system abstraction that provides a protected environment in which applications run. The applications are protected from each other to provide software fault isolation. To ease the labor of managing multiple applications and their environments, they co-exist within one operating system instance, and are usually managed as one entity.
The original operating environment, before any zones are created, is also called the "global zone" to distinguish it from non-global zones, The global zone is the operating system instance.
E: Exclusive-IP zones can use IPMP. IPMP is configured the same way in an exclusive-IP zone as it is on a system not using zones.
For shared-IP zones, IPMP can be configured in the global zone. F: Full IP-level functionality is available in an exclusive-IP zone. An exclusive-IP zone has its own IP-related state.
An exclusive-IP zone is assigned its own set of data-links using the zonecfg command. The zone is given a data-link name such as xge0, e1000g1, or bge32001, using the physical property of the net resource. The address property of the net resource is not set.
Note that the assigned data-link enables the snoop command to be used.
The dladm command can be used with the show-linkprop subcommand to show the assignment of data-links to running exclusive-IP zones.
NEW QUESTION 5
You are troubleshooting the failure of a computer to mount an NFS file system hosted by a server (hostname mars) in the local area network.
Select the three commands that will enable you to identify the problem.
- A. ping - s mars
- B. cat /etc/vfstab
- C. cat /etc/dfs/dfstab
- D. sharemgr show -v
- E. showmount -e mars
- F. rpcinfo -s mars | egrep ‘nfs|mountd’
B: The mount point Error. The following message appears during the boot process or in response toan explicit mount request and indicates a non-existent mount point.
Mount: mount-point /DS9 does not exist.
To solve the mount point error condition, check that the mount point exists on the client. Check the spelling of the mount point on the command line or in the /etc/vfstab file (B) on the client, or comment outthe entry and reboot the system.
Note: The /etc/vfstab file lists all the file systems to be automatically mounted at system boot time, with the exception of the /etc/mnttab and /var/run file systems.
This command displays all clients that have remotely mounted file systems that are shared from an NFS server, or only the file systems that are mounted by clients, or the shared file systems with the client access information. The command syntax is:
showmount [ -ade ] [ hostname ]
where -a prints a list of all the remote mounts (each entry includes the client name and the
directory), -d prints a list of the directories that are remotely mounted by clients, -e prints a list of the files shared (or exported), and hostname selects the NFS server to gather the information from. If hostname is not specified the local host is queried.
F: * mountd Daemon
This daemon handles file-system mount requests from remote systems and provides access control. The mountd daemon checks /etc/dfs/sharetab to determine which file systems are available for remote mounting and which systems are allowed to do the remote mounting.
* Commands for Troubleshooting NFS Problems
These commands can be useful when troubleshooting NFS problems. rpcinfo Command
This command generates information about the RPC service that is running on a system.

NEW QUESTION 9
Select two correct statements about the authentication services available in Oracle Solaris 11.
- A. Pluggable Authentication Modules (PAM) is used to control the operation of services such console logins and ftp.
- B. The Secure Shell can be configured to allow logins across a network to remote servers without transmitting passwords across the network.
- C. Secure Remote Procedure Calls (Secure RPC) provides a mechanism to encrypt data on any IP Socket connection.
- D. Pluggable Authentication Modules (PAM) is used to implement the Secure Shell in Oracle Solaris 11.
- E. Simple Authentication and Security Layer (SASL) provides a mechanism to authenticate and encrypt access to local file system data.
A: Pluggable Authentication Modules (PAM) are an integral part of the authentication mechanism for the Solaris. PAM provides system administrators with the ability and flexibility to choose any authentication service available on a system to perform end-user authentication.
By using PAM, applications can perform authentication regardless of what authentication method is defined by the system administrator for the given client.
PAM enables system administrators to deploy the appropriate authentication mechanism for each service throughout the network. System administrators can also select one or multiple authentication technologies without modifying applications or utilities. PAM insulates application developers from evolutionary improvements to authentication technologies, while at the same time allowing deployed applications to use those improvements.
PAM employs run-time pluggable modules to provide authentication for system entry services.
E: The Simple Authentication and Security Layer (SASL) is a method for adding authentication support to connection-based protocols.
Simple Authentication and Security Layer (SASL) is a framework for authentication and data security in Internet protocols. It decouples authentication mechanisms from application protocols, in theory allowing any authentication mechanism supported by SASL to be used in any application protocol that uses SASL. Authentication mechanisms can also support proxy authorization, a facility allowing one user to assume the identity of another. They can also provide a data security layer offering data integrity and data confidentiality services. DIGEST-MD5 provides an example of mechanisms which can provide a data-security layer. Application protocols that support SASL typically also support Transport Layer Security (TLS) to complement the services offered by SASL.

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.
The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.
NEW QUESTION 13
You want the system to generate an email notification each time one of the services has changed its state. Which option would send an email message to the system administrator whenever a service changes to the maintenance state?
- A. Use the setsc command in ALOM to enable the mail alerts to be sent to a specified email address whenever the fault management facility detects a service change to the maintenance state.
- B. Make an entry in the /etc/syslog.conf file to instruct syslogd to send an email alert when it receives a message from the SMF facility that a service has changed to the maintenance state.
- C. Use the svccfg setnotify command to create a notification and send an email when a service enters the maintenance state.
- D. Use the scvadm command to enable the notification servic
- E. Set the –g maintenance option on the netnotify service to send an email when a service enters the maintenance state.
This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally, you would only select SNMP if you already have SNMP configured for some other reason.
By default, SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring, you can configure additional traps for other state transitions.
1. Become an administrator or assume a role that includes the Service Management rights profile.
2. Set notification parameters.
The following command creates a notification that sends email when transactions go into the maintenance state
# /usr/sbin/svccfg setnotify -g maintenance mailto:firstname.lastname@example.org
NEW QUESTION 14
On which is the open boot prom available?
- A. x86 only
- B. x86 64-Bit only
- C. SPARC only
- D. both x86 and x86 64-Bit
- E. x86, x86 64-Bit and SPARC
No OpenBoot Environment on the Intel Platform. The Intel environment has no OpenBoot PROM or NVRAM. On Intel systems, before the kernel is started, the system is controlled by the basic input/output system (BIOS), the firmware interface on a PC. Therefore, many features provided by OpenBoot are not available on Intel systems.
Note: The Open Boot PROM (OBP) bootloader only exists within SPARC. Before Solaris 10 01/06, the bootloader for Solaris x86 was a Sun customized bootstrap software. After Solaris 10 01/06, it uses GRUB, a well known bootloader that's commonly used in the
With GRUB, it's much easier to make the system dual-boot Linux and Solaris. GRUB extends the capabilities of the bootloader that was not available previously such as the ability to boot from a USB DVD drive. Those who have used Linux will be quite familiar with GRUB and its options.
NEW QUESTION 15
You have a ZFS file system named /dbase/oral and you want to guarantee that 10 GB of storage space is available to that dataset for all data, snapshots, and clones.
Which option would you choose?
- A. zfs set refreservation=10g dbase/oral
- B. zfs set quota=10g dbase/oral
- C. zfs set refquota=10g dbase/oral
- D. zfs set reservation=10g dbase/oral
A ZFS reservation is an allocation of disk space from the pool that is guaranteed to be available to a dataset. As such, you cannot reserve disk space for a dataset if that space is not currently available in the pool. The total amount of all outstanding, unconsumed reservations cannot exceed the amount of unused disk space in the pool. ZFS reservations can be set and displayed by using the zfs set and zfs get commands. For example:
# zfs set reservation=5G tank/home/bill
# zfs get reservation tank/home/bill NAME PROPERTY VALUE SOURCE
tank/home/bill reservation 5G local

- A. unsuccessful attempt
- B. successful attempt
- C. The attempt was from a pseudo terminal, and not the console.
- D. The attempt was from a user that is in the adm group, same as root.
- E. Time zone is not set.
The sulog file, /var/adm/sulog, is a log containing all attempts (whether successful or not) of the su command. An entry is added to the sulog file every time the su command is executed. The fields in sulog are: date, time, successful (+) or unsuccessful (-), port, user executing the su command, and user being switched to. In the preceding example, all su attempts were successful, except for the attempt on 2/23 at 20:51, when user pete unsuccessfully attempted to su to user root.
Look for entries where an unauthorized user has used the command inappropriately. The following entry shows a successful (indicated by +) su from user userid to root.
SU 03/31 12:52 + pts/0 <userid>-root
