Oracle 1Z0-105 Online Questions & Answers

• Question 111:

  Examine the code fragment from /etc/tgt/targets.conf:

  backing-store /iSCSIsharedDisk/physDisk1.img

  write-cache off

  backing-store / iSCSIsharedDisk/physDisk2.img

  initiator-address 192.0.2.105

  initiator address 192.0.2.106

  write-cache off

  backing-store /iSCSIsharedDisk/physDisk3.img

  write-cache off

  Which statement is true?

  A. Only the target identified by the iqn ending with mypc:2 is visible. This target is visible to the specific clients identified by the initiator address.
  B. The initiator-address syntax in not valid. The address value should be specified as an iqn, not an IP address. This causes an error, and only iqns ending with mypc:1 and mypc:3 are visible.
  C. All targets are visible to prospective clients, but the target iqn ending with mypc:2 is visible exclusively to the specified IP addresses.
  D. The initiator-address syntax is not valid. The address value must be specified as an iqn, not an IP address. The initiator-address parameters are ignored and all targets are visible without restriction.
  B. The initiator-address syntax in not valid. The address value should be specified as an iqn, not an IP address. This causes an error, and only iqns ending with mypc:1 and mypc:3 are visible.

• Question 112:

  You dynamically configure a system to concurrently run CPU-intensive tasks T1, T2, and T3 using these commands:

  

  Which two statements are true? (Choose two.)

  A. When task T1 is running in cgroup A1, task T2 is running in cgroup A2, and task T3 is running in cgroup A3, the system tries to ensure that equal CPU power is given to tasks T1, T2, and T3 and they share the same CPU.
  B. When task T1 is running in cgroup A3, all configured CPU resources are used and the system ensures that tasks T1 and T3 run on different CPUs.
  C. When task T1 is running outside cgroup A1, A2 and A3 and task T3 is running in cgroup A1, the system prefers task T3 over task T1 while they share the same CPU.
  D. When task T1 is running in cgroup A1 and task T2 is running in cgroup A1, all configured CPU resources are used and the system ensures that equal CPU power is given to tasks T1 and T2 and T3.
  B. When task T1 is running in cgroup A3, all configured CPU resources are used and the system ensures that tasks T1 and T3 run on different CPUs.
  D. When task T1 is running in cgroup A1 and task T2 is running in cgroup A1, all configured CPU resources are used and the system ensures that equal CPU power is given to tasks T1 and T2 and T3.

  B. one SUBNET definition, without a RANGE definition, and multiple HOST definitions
  C. only one SUBNET definition with a RANGE definition

  C. The probe name is read.
  D. The probe name is entry.
  E. The probe name is not specified in this command, but it is implied through adjacent colons.
