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.)

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

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

CWithout test partners, in.mpathd cannot detect the failure of a subinterface.

DArbitrary hosts on the subnet are detected by sending an 'all hosts' (224.0.0.1) multicast packet

EArbitrary hosts on the subnet are detected by sending an 'all routers' (224.0.0.2) multicast packet.

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

Question 4

The rctladm command reports the following:

# rctladm |grep task.max.lwps task.max-lwps syslog=notice [ count 1

Which of the following correctly describes the system configuration?

AA message will be logged with syslogd when the number of notice messages generated by the resource control threshold meets or exceeds the value specified with [count]

BA message will be logged with sysloqd when the number of violations generated by the resource control threshold meets or exceeds the value specified with [count].

CThe global resource control monitoring for the task.max-lwps resource control has been enabled and syslog messaging for that resource control has been set to notice. However, because the [count] value has not been specified, there is no threshold set for the resource to monitor. The configuration to monitor the task.max-lwps resource control is incomplete.

DThe global resource control monitoring for the task.max-lwps resource control has been enabled, syslog messaging for that resource control has been set to notice.

Correct : D

Which four statements are true for support of ZFS encryption?

AThe encrypted file system must have been created in Oracle Solaris 11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system in that zpool Finally, move or copy the data from the existing ZFS file system into the new encrypted ZFS file system.

Bif you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30, minimum.

CZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

DZFS encryption requires that the ZFS Dataset Encryption package be installed.
E If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 21, minimum. D f Encryption is supported at the pool or dataset (file system) level

FEncryption is supported at the pool level only and every file system in the pool will be encrypted.

GEncryption is supported at the pool level only and every file system in the pool will be encrypted.

HYou cannot create an encrypted file system in a zpool that was created prior to Oracle Solaris 11.
Create a new zpool in Solaris 11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.
