Oracle 1Z0-878 Online Questions & Answers

  • Question 231:

    You are the system administrator for a system running a business critical database application. To maintain data availability, you are using Solaris Volume Manager and have several two-way mirrors configured. You also have several hot spares created. When creating the hot spare pool, you added devices in this order:

    -

    a 1.0 gigabyte slice

    -

    a 2.2 gigabyte slice

    -

    a 9.8 gigabyte slice

    -

    a 3.2 gigabyte slice

    -

    a 6.5 gigabyte slice

    Your monitoring software sends you an email indicating that one sub-mirror of a two-way Solaris Volume Manager Software mirror has gone offline because of a hardware error. The sub-mirror that was taken offline was 2.3 gigabytes in size. Which hot spare component will the Solaris Volume Manager software use to recreate the sub-mirror automatically?

    A. The 2.2 gigabyte component
    B. The 3.2 gigabyte component
    C. The 6.5 gigabyte component
    D. The 9.8 gigabyte component

  • Question 232:

    The Solaris 10 OS supports the sharing of remote file resources and presents them to users as if they were local files and directories. The primary distributed file system (DFS) type supported by Solaris 10 OS is NFS. Which three statements are true about NFS as supported by Solaris 10 OS? (Choose three.)

    A. The NFS server supported by Solaris 10 OS uses TCP exclusively.
    B. An NFSv4-capable server can communicate with clients that use NFSv3 or earlier.
    C. NFS uses the Remote Procedure Call (RPC) method of communication.
    D. The NFS server supported by Solaris 10 OS can only communicate with clients using NFSv4.
    E. The Solaris 10 OS uses NFSv4 by default when sharing a directory or accessing a named file.
    F. The NFS server on Solaris 10 OS is started at bootup and is configured by modifying the /etc/rc.local file.

  • Question 233:

    What are four types of AutoFS maps? (Choose four.)

    A. Slave
    B. Direct
    C. Binary
    D. Master
    E. Indirect
    F. Sparse
    G. Special
    H. Cannonical

  • Question 234:

    SystemA has a file system named /data/dbase that is being shared. systemB needs to mount that file system so that users on systemB can access the data remotely on systemA. The information in the /data/ dbase file system is confidential and access to that data must be restricted so that only user1 and user2 can access the data from systemB.

    Which answer describes a method to protect the data on systemA so that only specific users on system can access that data?

    A. Share the file system on systemA as follows: share -F nfs -o rw=systemB /data/dbase. On systemB, mount the file system as follows: mount -F nfs -o hard,rw=user1,user2 \ systemA:/data/dbase /data
    B. Share the file system on systemA as follows: share -F nfs -o rw=systemB:user1,user2 /data/dbase
    C. On systemA, protect the /data/dbase directory using conventional UNIX permissions so that only user1 and user2 can access the data.
    D. On systemA, protect the /data/dbase directory using conventional UNIX permissions so that only user1 and user2 can access the data. Then, share the file system on systemA as follows:

  • Question 235:

    In order to PXE boot a system, many of the following macros must be defined in DHCP.

    SrootIP4 SrootNM SrootPTH SinstIP4 SinstNM SinstPTH SrootOpt SbootFIL SbootRS SsysidCF SjumpsCF Substituting

    With the name of a macro from above, and with the appropriate configuration string, which command must be used to define each macro?

    A. dhcp -A -s -d
    B. dhtadm -A -s -d
    C. dhcpmgr -A -s -d
    D. dhcpadm -A -s -d

  • Question 236:

    You have just made the following modification to the sysiog configuration file:

    *.alert;kern.err;daemon.err operator

    What is the next step to implement this change?

    A. Save the file, sysiog will pick up the changes made to the configuration file.
    B. svcadm refresh system--log
    C. svcadm restart svc:/system/sys1ogd:default
    D. svcadm stop svc:/system/sys1ogd:default svcadm start svc:/system/sys1ogd:default

  • Question 237:

    You are creating a new direct map to allow a new application that has been installed on an application server to become available. Which two commands activate the new map? (Choose two.)

    A. /usr/sbin/mountall
    B. /usr/sbin/automount
    C. /usr/bin/pkill -HUP inetd
    D. /usr/sadm/bin/smreg add -d /etc/auto_master
    E. /usr/sbin/svcadm restart svc:/system/fileystem/autofs

  • Question 238:

    A user's workstation is configured to mount /archive from a remote system through NFS using the following entry in /etc/vfstab:

    #device device mount FS fsck mount mount

    #to mount to fsck point type pass at boot options

    speedy:/archive - /archive nfs - yes

    To improve performance, a second NFS server, named pokey, is being added to serve out the identical file system.

    You notice that the workstation is attempting to mount /archive read-write. The /archive file system contains old archived data and should not be modified. You decide that the user's workstation should mount /archive read-only instead.

    Which two changes must you make to allow the workstation to use the NFS server pokey and speedy and to correct the read-write/read-only mounting issue? (Choose two.)

    A. change the mount options field to ro
    B. change the mount options field to ro=speedy,pokey
    C. change the device to mount field to speedy,pokey:/archive
    D. change the device to mount field to read pokey:/archive/speedy

  • Question 239:

    Which three can be described with the name SUNW.i86pc? (Choose three.)

    A. a processor type which can use PXE boot
    B. a file system type created during PXE boot
    C. a DHCP client class used during PXE boot

    A. Only SPARC-based systems can perform a Solaris Live Upgrade.
    B. When you create an inactive boot environment, / (root) can be located on a Veritas Volume Manager volume (VxVM).
    C. There must be enough space to use the lucreate command to create separate file systems for root (/) and / kernel.
    D. None critical file systems must be on the same physical disk as the critical file systems to be shared between boot environments.
    E. When you create an inactive boot environment, / (root) can be on different physical disk or the same disk as the active root (/) file system.
    F. The release of the Solaris Live Upgrade packages you use to perform live upgrade tasks must match the release of the OS you are upgrading to.
