Question No.111

Solaris 11 includes a redesigned software packaging model: the Image Packaging system. Which three describe advantages of the Image Packaging System over the previous Solaris 10 SVR4 packaging model?

  1. Eliminates patching of the software package

  2. Makes the patching process more efficient with less downtime

  3. Eliminates OS version upgrade

  4. Allows for the installation of the OS without a local DVD or installation server

  5. Allows the use of a repository mirror to speed up package operation

  6. Allows users to publish their own software package in a software repository

Correct Answer: ADF

Explanation:

A: In contrast to the SVR4 packaging model used in earlier Oracle Solaris releases, IPS eliminates the need for patching.

  2. The disk volume provided by the server is referred to as the LUN and can be accessed by an iSCSI initiator.

  3. The disk volume provided by the server is referred to as the target.

  4. The iSCSI initiator is configured on the server.

  5. The iSCSI initiator is configured on the client.

Correct Answer: ACD

Question No.113

To simplify administration of a network, the decision was made to use bridging rather than routing Your network includes three Oracle Solaris 11 systems,

en-tiny cib uiiuyo yiuviumy reuunuaiu pauiways.

You previously created the bridges on each system with the following commands: SystemA#dladmcreate-bridge-1 netl -1 net2 bridgeA

SystemB # dladm create-bridge -1 netl -1 net2 bndgeB SystemC # dladm create-bridge -1 netl -1 net2 bndgeC

You notice that network performance is less than expected, and packets between networks X and

Z are being forwarded by bridgeA and bridgeB, rather than being forwarded directly by bndgeC. Select the solution.

  1. SystemC # dladm modify-bndge -p stp bridgeC

  2. SystemA # dladm modify-bridge -p stp bridgeA SystemB # dladm modify-bridge -p stp bndgeB SystemC # dladm modify-bridge -p stp bridgeC

  3. SystemC # dladm modify-bridge -p trill bridgeC

  4. SystemA # dladm modify-bridge -p trill bridgeA SystemB # dladm modify-bridge -p trill bndgeB SystemC # dladm modify-bridge -p trill bndgeC

  5. SystemC # ipadm set-prop -p forwarding=on bridgeC

  6. SystemC # dladm set-linkprop -p promiscuous=on bridgeC

Correct Answer: E

Question No.114

Which four statements describe the function of the svc://system/install/server;default service? (Choose four.)

  1. it associates an install image with a named install service.

  2. Client systems use the service name to find the correct install image.

  3. Every Oracle Solaris 11 system uses this service to find its IPS publisher and to locate its IPS repository.

  4. A server can have multiple instances of the install/server service, each associated with one boot image.

  5. This service is not present on a server by default.

  6. This service is present on every Oracle Solaris 11 system, but it is not enabled.

  7. A new install/server service cannot be created without DHCP.

  8. An Al install server can have several instances of this service, but can have only one install service running at a time.

Correct Answer: EFGH

Question No.115

Which three installation options allow for a quot;hands-freequot; and quot;unattendedquot; installation of the Oracle Solaris 11 environment? (Choose three.)

  1. Jumpstart

  2. LiveCD

  3. a text installation over the network

  4. an Automated Installation performed on an x86 client

  5. an Automated Installation using media from a local DVD or USB drive

  6. an Automated Installation using a networked repository

Correct Answer: DEF

Question No.116

Your server hangs intermittently and you believe it may be due to either faulty hardware or a

driver. The support technician has told you to generate a live core dump of all memory pages for further analysis Your dump configuration is:

Dump content: kernel pages

Dump device: /dev/zvol/dsk/rpool/dump (dedicated) Savecore directory: /var/crash

Savecore enabled: yes Save compressed: on

You don#39;t have enough space on the current dump device, so you need to store the dump on

/dev/zvol/dsk/pool2/dump

Which option would you select to change the dump location for the next core dump and capture the content of all memory pages as requested by the support technician?

  1. dumpadm -d /dev/zvol/dsk/pool2/dump

  2. dumpadm -d /dev/zvol/dsk/pool2/dump -c all

  3. dumpadm -d /dev/zvol/dsk/pool2/dump -c curproc

  4. dumpadm -s /dev/zvol/dsk/pool2/dump -c all

  5. dumpadm -s /dev/zvol/dsk/pool2/dump

Correct Answer: D

Question No.117

You are configuring NFS on a server. Select the two statements that are true.

  1. Resources listed in /etc/dfs/dfstab are automatically shared on boot up.

  2. A directory cannot be shared if a subdirectory below it is already shared.

  3. Renaming a share created with the zfs set share command is not supported.

  4. NFS and SMB protocols cannot be used simultaneously to share the same directory.

Correct Answer: AC

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.

Question No.118

On server A, you enter the following command to add a static route to serverA route -p add -host 192.168.1.101 192.168.1.101 -static

What is the purpose of this command?

  1. to temporarily bypass IP Filter rules

  2. to specify an IPMP target IP address to in.mpathd

  3. to specify routing to an adjacent network when in.rdisc is not used

  4. to specify routing to an adjacent network when in.routed is not used

  5. to ensure the IP address for serverB is not flushed from the ARP cache

  6. to optimize link aggregation using a direct connection between two systems

Correct Answer: B

Explanation:

Note:

# route -p add -host destination-IP gateway-IP -static where destination-IP and gateway-IP are IPv4 addresses of the host to be used as a target.

For example, you would type the following to specify the target system 192.168.10.137, which is on the same subnet as the interfaces in IPMP group itops0:

$ route -p add -host 192.168.10.137 192.168.10.137 -static This new route will be automatically configured every time the system is restarted. If you want to define only a temporary route to a target system for probe-based failure detection, then do not use the -p option.

Question No.119

You want the system to generate core files when an application crashes, but you want only root to be able to view the core files. The current core configuration is:

global core file pattern: /var/core/core %f.%p global core file content: default

init core file pattern: /var/core/pprocess/core.%f.%pp init core file content: default

global core dumps: enabled

perprocess core dumps: enabled global setid core dumps disabled

per-process setid core dumps: disabled global core dump logging disabled

Select the option that describes the change that needs to be made to the core dump configuration to meet this requirement.

  1. coreadm d process

  2. coreadm -i /var/core/core.%f %p

  3. coreadmd global

  4. coreadm -d process -d global -e global-setid -e proc-setid

  5. Make this change to the /etc/coreadm.conf file: per-process core dumps: disabled

Correct Answer: A

Question No.120

You are planning the configuration for IPMP (IP Multipathing).

Best practice dictates that you must ensure that there is at least one neighbor on each subnet that responds to ICMP echo request probes to detect link failure.

Which two of the following statements are true regarding the link failure detection process? (Choose two.)

  1. By default, in.mpathd selects the default router as the only test partner.

  2. The default failure detection time is 60 seconds (12 consecutive probes).

  3. Without test partners, in.mpathd cannot detect the failure of a subinterface.

  4. Arbitrary hosts on the subnet are detected by sending an quot;all hostsquot; (224.0.0.1) multicast packet.

  5. Arbitrary hosts on the subnet are detected by sending an quot;all routersquot; (224.0.0.2) multicast packet.

  6. Arbitrary hosts on the subnet are detected by examining the ARP cache (Internet-to- MAC address translation table).
