Oracle 1Z0-580 Sample Questions:

01. Hosts at a branch site fetch the solaris catalog from Oracle without trouble but download package files slowly. A colleague stands up a local server that holds a full copy of the package content, and the goal is for clients to keep getting catalog and metadata from Oracle while pulling file content from the local server.
How should that local server be added to the publisher configuration?
a) As a brand-new publisher named localsrv with its own origin, so the two publishers are searched in priority order.
b) As a replacement origin with pkg set-publisher -O http://localsrv/ solaris, so every catalog and content request is redirected to the local server.
c) As an additional origin with pkg set-publisher -g http://localsrv/ solaris, so the client treats it as a second independent package source carrying its own catalog.
d) As a mirror, with pkg set-publisher -m http://localsrv/ solaris, so file content is served locally while the origin still supplies the catalog.
 
02. While planning the root pool for the new host store01, an administrator weighs disk layouts and needs each candidate to still yield a bootable Oracle Solaris 11 system.
Which layouts are valid choices for a bootable root pool?
(Choose two.)
a) A stripe across two separate top-level virtual devices for capacity.
b) A raidz group spread across three disks for parity protection.
c) A single whole disk dedicated to the root pool.
d) A pool built on a ZFS volume exported from another pool.
e) A two-way mirror of two whole disks for boot redundancy.
 
03. An administrator must present block storage backed by the pool store to a remote host as an iSCSI LUN.
Which sequence correctly exposes ZFS-backed storage through COMSTAR?
a) Create a ZFS volume with zfs create -V, register it as a backing logical unit with sbdadm / stmfadm, then export it through the COMSTAR iSCSI target.
b) Create a ZFS volume, set the sharesmb=on property on it, and the zvol is then automatically advertised across the network to initiators as a ready-to-use iSCSI LUN.
c) Take a snapshot of a ZFS filesystem and use zfs send to stream that snapshot to the remote host, presenting it there as a block LUN.
d) Create a ZFS filesystem, set the sharenfs=on property, and have the remote host mount that NFS export over an iSCSI session.
 
04. On the freshly installed server edge05, an administrator finds an unnecessary network-facing service running and must stop it now and keep it off across every subsequent reboot.
Which action accomplishes that?
a) Mask it at the packaging layer with pkg uninstall so the service is disabled on reboot.
b) Temporarily disable it with svcadm disable -t so it stays off after reboot.
c) Persistently disable it with svcadm disable on its FMRI so it stays off after reboot.
d) Remove its configuration with svccfg delete so the service stops immediately and permanently.
 
05. A team debates using the Automatic NCP versus a fixed NCP for a datacenter server that must always hold one known static address.
Which two statements are accurate?
(Choose two.)
a) A fixed NCP automatically switches to a surviving link when one goes down, exactly the way an IPMP group does.
b) A fixed NCP applies an administrator-defined, unchanging ipadm configuration, which suits a server with a known static address.
c) The Automatic NCP reacts to link and connection changes and typically obtains addressing by DHCP, which suits mobile clients.
d) Only one NCP may be defined on a Solaris 11 system at any given time.
e) The Automatic NCP guarantees the same static address across every reboot regardless of which link is currently active.
 
06. edge05 must spread inbound client connections across three back-end web servers at the transport layer, and it should stop sending to any server that fails a health check.
Which Solaris 11 facility provides this?
a) The Integrated Load Balancer configured with ilbadm.
b) An IPMP group spanning the three servers.
c) A flowadm flow that distributes connections by destination port.
d) A link aggregation created with dladm create-aggr across the back-end paths.
 
07. While preparing an unattended Solaris 11 install for a batch of database servers, an administrator must define the target boot disk, the ZFS root pool layout, and the exact set of IPS packages to install.
Where are those choices specified in the Automated Installer setup?
a) In the client's SMF first-boot service, which picks the disk and downloads the IPS packages when the system boots.
b) In the System Configuration (SC) profile, which describes the disk target, the ZFS layout, and the IPS package set.
c) In a per-client repository manifest that pkgrepo generates for each install client.
d) In the AI manifest, which describes the install target disk, the ZFS layout, and the IPS packages to be installed.
 
08. For disaster recovery, nightly changes to vault/db on dbnode2 are replicated to a standby pool on host edge05 using an incremental zfs send -i stream.
Which two conditions must hold for each incremental replication to apply successfully?
(Choose two.)
a) Compression must be disabled on both pools or the incremental stream will be rejected.
b) A newer snapshot of vault/db must be taken on the source before each incremental zfs send -i.
c) The source and destination pools must be imported with the same cachefile so that the incremental streams are recognized as matching.
d) The destination dataset must be mounted read-write and modified between receives to stay in sync.
e) A snapshot common to both sides must still exist on the receiving pool to serve as the incremental base.
 
09. Before applying a large batch of package updates on dbnode2, an administrator wants a guaranteed way to fall back to the exact pre-update system if the new software misbehaves, without manually snapshotting the root pool first.
What does running pkg update provide toward that goal?
a) It writes the changes into the active boot environment and stores a ZFS snapshot named for the transaction that must be rolled back by hand.
b) It automatically creates a new boot environment holding the updated image and leaves the current BE intact and bootable for rollback.
c) It updates the packages in place and relies on pkg revert to undo the whole transaction afterward.
d) It refuses to proceed unless the administrator first runs beadm create to prepare a target boot environment by hand.
 
10. The local repository at /export/IPSrepo on repo01 is now populated, and client systems must reach it over HTTP rather than by a local file path.
Configuring and enabling which SMF service turns that repository into a network-accessible depot?
a) svc:/application/pkg/system-repository
b) svc:/application/pkg/mirror
c) svc:/application/pkg/server
d) svc:/network/http:apache
