Oracle Solaris 11 Advanced System Administration

Question No: 41

Your organization uses NFS to share data from Oracle Solaris servers to Oracle Solaris clients. The server currently has an NFS share configured for the rpool/export/data file system. A client is currently mounting this file system. As administrator, you add a new file system rpool/export/data/yesterdays_data, and copy data into the new file system.

Which action is required for the client currently mounting the rpool/expor/data file system to access the new data?

  1. The rpool/export/data/yesterdays_data file system must be mounted.

  2. No action is required because the data is automatically made available.

  3. The rpool/export/data file system must be remounted.

  4. The nfs/client server must be restarted.

Question No: 42

Which scheduling class distributes CPU resources among its processes based on assigned importance?

  1. Fair Share Scheduler (FSS)

  2. Real-Time (RT)

  3. Fixed-priority (FX)

  4. Timesharing (TS)

Answer: C

Explanation: The FX scheduler provides a scheduling policy for processes that require user or application control of scheduling priorities. The priorities of processes that run under FX are fixed.

The FX class provides a fixed-priority preemptive scheduling policy. This policy is used by processes that require user or application control of scheduling priorities but are not dynamically adjusted by the system. By default, the FX class has the same priority range as the TS, IA, and FSS classes. The FX class allows user or application control of scheduling priorities through user priority values assigned to processes within the class.

These user priority values determine the scheduling priority of a fixed-priority process relative to other processes within its class.

Incorrect:

Not A: The fair share scheduling class enables you to allocate CPU time based on shares instead of the priority scheme of the timesharing (TS) scheduling class.

Not D: The goal of the time-sharing policy is to provide good response time to interactive processes and good throughput to CPU-bound processes. The scheduler switches CPU allocation often enough to provide good response time, but not so often that the system spends too much time on switching. Time slices are typically a few hundred milliseconds.

The time-sharing policy changes priorities dynamically and assigns time slices of different lengths.

Question No: 43

Your company#39;s security policy prohibits access to the Internet. You already installed an instance of Oracle Solaris 11 on an M-series server for base testing. You used the text install media to install the system. You also installed a package repository on the same system.

There are 10 M-series servers that have just been installed on the local network.

Can you immediately install an AI server on your testing machine order to install Oracle Solaris 11 on these 10 servers?

  1. Yes, by using the existing Solaris 10 Jumpstart server.

  2. Yes, by using the text install media for the AI software.

  3. Yes, by using the Installed package repository.

  4. No, you must download the AI .iso image from Oracle first.

  5. No, the Solaris large-server group must be installed because it contains the AI setup tools.

  6. No, the Solaris 11 full n repository must be installed on the AI server.

  7. No, you must have a prebuilt image that was created by the distribution constructor.

Answer: D

Question No: 44

There is a valid SMF manifest located underneath the /var/svc/manifest directory. Which four methods can be used to add it to the services repository?

  1. Reboot the system.

  2. Restart the early-manifest-import service.

  3. Use the svccfg apply command.

  4. Restart the manifest-import service.

  5. Use the svccfg import command.

Answer: A,C,D,E

Explanation: AD: Manifests from the standard directory trees /lib/svc/manifest and

/var/svc/manifest are processed during system boot and anytime an administrator or program runs:

$ svcadm restart manifest-import C: svccfg

apply subcommand

If the argument is a service profile or manifest, apply the configuration to the admin layer of the SMF repository. Services, instances, property groups, and properties will be created as necessary.

E: import [-V] [file | directory]

svccfg import on a file in a system-managed filesystem location (subdirectories of

/lib/svc/manifest and /var/svc/manifest) invokes: svcadm restart manifest-import.

Placing your manifests in a system-managed location and invoking svcadm restart manifest-import to import them is the recommended practice.

svccfg import on files in other locations imports their properties as administrative customization into the admin layer. It is equivalent to:

svccfg apply [file | directory] Incorrect:

not B: Manifests are processed in two different phases during boot.

The service svc:/system/early-manifest-import:default, a pseudo service, is responsible for the first manifest processing. This service processes only manifests from the

/lib/svc/manifest directory tree before svc.startd(1M) initializes any services thus enabling services delivered in /lib/svc/manifest to always start with their most updated definition.

Since this is a pseudo service, svcadm(1M) commands are ignored though svcs(1) can be used to observe status and get log file information.

The svc:/system/manifest-import:default service handles the second manifest processing and imports manifest files from both /lib/svc/manifest and /var/svc/manifest directory trees, in that respective order.

Question No: 45

Which two conditions must exist in order to add a new link to an aggregation?

  1. The new link appears in the output of dladm show-phys.

  2. The new link may already support an active interface.

  3. The LACP policy must be set to L4.

  4. The link may currently be in any state.

  5. The new link has the same MAC address as the existing links.

Answer: A,D Explanation: A: Note:

Use dladm show-phys to obtain information about the system#39;s datalinks in relation to the physical NICs with which they are associated. Used without any options, the command displays information similar to the following:

# dladm show-phys

LINK MEDIA STATE SPEED DUPLEX DEVICE

net0 Ethernet up 100Mb full e1000g0 net1 Ethernet down 0Mb – nge0 net2 Ethernet up 100Mb full bge0 net3 Infiniband – 0Mb – ibd0

  • Your link aggregation configuration is bound by the following requirements:

    /You must use the dladm command to configure aggregations.

    / (not B) An interface that has been created cannot become a member of an aggregation.

    /All interfaces in the aggregation must run at the same speed and in full-duplex mode.

    / (not E) You must set the value for MAC addresses to “true” in the EEPROM parameter local-mac-address? For instructions, refer to How to Ensure That the MAC Address of an Interface Is Unique.

    Question No: 46

    Which two statements describe projects and/or tasks?

    1. A task is a resource container for one process.

    2. Project resource controls are evaluated before task resource controls.

    3. Every user belongs to one or more projects.

    4. Every task associates a project with a process.

    5. A project is optional and not every user must belong to a project.

    Answer: C,D

    Explanation: C: a user must be assigned to a default project, the processes that the user launches can be associated with any of the projects of which that user is a member.

    D: How to Create a New Task

    1. Log in as a member of the destination project, booksite in this example.

    2. Create a new task in the booksite project by using the newtask command with the -v (verbose) option to obtain the system task ID.

      machine% newtask -v -p booksite 16

      The execution of newtask creates a new task in the specified project, and places the user#39;s default shell in this task.

    3. View the current project membership of the invoking process. machine% id -p

    uid=100(mark) gid=1(other) projid=4113(booksite) The process is now a member of the new project.

    Note:

  • Projects are collections of tasks, which are collections of processes.

  • Projects and tasks are used to label workloads and separate them from one another.

    Incorrect:

    Not A: The task collects a group of processes into a manageable entity that represents a workload component.

    Not E: If no default project is found, the user#39;s login, or request to start a process, is denied.

    Question No: 47

    The output of the ppriv command lists four privilege sets. Which option best describes the Inherited privilege set?

    1. It is the privilege set that nonroot users may inherit.

    2. It is the privilege set an effective-user process may inherit.

    3. It is the privilege set only privilege-aware child processes may inherit.

    4. It is the privilege set the current process inherited.

    Answer: D Explanation:

    Note:

  • ppriv

  • inspect or modify process privilege sets and attributes

    Question No: 48

    You administer a server running a global zone with no virtual networking. Consider the following configuration:

    Ensurepass 2018 PDF and VCE

    Which is a valid IPMP configuration for this server?

    1. net0 and net1 must be configured into an IPMP group, net2 can be configured into its own IPMP group, and net0 or net1 can be configured as a standby interface.

    2. net0 and net1 must be configured into one IPMP group, net2 and net3 must be configured into a second IPMP group, and all interfaces can be configured for link detection.

    3. net1 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP group, and net3 can be configured as a standby interface.

    4. net0 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP group, and net3 can be configured as a standby interface.

    Answer: A

    Explanation: Must be in the same network range (see * below). Different speeds are fine (see ** below).

    • An IP multipathing group, or IPMP group, consists of one or more physical interfaces on

    the same system that are configured with the same IPMP group name. All interfaces in the IPMP group must be connected to the same IP link (A, not B, not C, Not D).

    ** The same (non-null) character string IPMP group name identifies all interfaces in the group. You can place interfaces from NICs of different speeds within the same IPMP group, as long as the NICs are of the same type. For example, you can configure the interfaces of 100-megabit Ethernet NICs and the interfaces of one gigabit Ethernet NICs in the same group. As another example, suppose you have two 100-megabit Ethernet NICs. You can configure one of the interfaces down to 10 megabits and still place the two interfaces into the same IPMP group.

    Question No: 49

    You detected a failure of net0 in the IPMP group named ips1. The server hosting the failed NIC supports dynamic reconfiguration. Which statement is true regarding the replacement of the hardware interface?

    1. The NIC must be replaced with an identical physical interface card type.

    2. The NIC will be configured after replacement with the dladm command.

    3. The devfsadm command will be used to discover the replacement NIC.

    4. The replacement NIC must occupy the same bus slot as the original NIC .

    Answer: B

    Explanation: When an underlying interface of an IPMP group fails, a typical solution would be to replace the failed interface by attaching a new NIC. RCM records the configuration information associated with any NIC that is detached from a running system. If you replace a failed NIC with an identical NIC, then RCM automatically configures the interface according to the persistent configurations that had been previously defined by using the ipadm command.

    Incorrect:

    Not A, not D: You can replace a failed NIC with a different NIC, provided that both are the same type, such as Ethernet. In this case, RCM plumbs the new interface after it is attached. If you did not use customized link names when you first configured your interfaces, then you will have to configure the new NIC before you can add the interface to the IPMP group.

    Not C: devfsadm, devfsadmd- administration command for /dev and /devices

    Note:

    * 1. On the system with the IPMP group configuration, assume the Primary Administrator role or become superuser.

    1. Display the test address configuration

    2. Remove the physical interface.

    1. Replace the physical interface.

      Question No: 50

      Which option describes how to revert a service back to a previous version?

      1. Issue the svccfg delcust command.

      2. Issue the revetsnap command.

      3. Issue the restore_repository command.

      4. Issue the svccfg revert command.

    Answer: D Explanation: svccfg

    subcommand: revert [snapshot]

    Reverts the administrative customizations of the currently selected instance and its service to those recorded in the named snapshot. If no argument is given, use the currently selected snapshot and deselect it on success.

    Incorrect:

    Not A: Rollback to as-delivered system: svccfg delcust svccfg

    subcommand: delcust [-M] [pattern]

    Delete any administrative customizations for the current selection. If an argument is supplied, it is taken as a glob pattern and only property groups and properties with names that match the argument are deleted.

    Not B: There is no command revetsnap

    Not C: Run the command /lib/svc/bin/restore_repository, and follow its instructions to restore one of the automatic backup copies of the repository. Upon successful completion, the system or local zone will be rebooted, and the restored repository will take effect.
