• Question 72:

  What is the most commonly used measurement unit for describing a UPS?

  A. kW

  B. VA

  C. Amps

  D. kJ

  Correct Answer: B

  {\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fnil\fcharset0 MS Shell Dlg 2;}} \viewkind4\uc1\pard\lang2052\f0\fs17 Industry Standard Architecture - Student Guide 2 - Page 187\par An uninterruptible power supply (UPS) system provides power to the server in case of loss of electrical power from the main building power. The UPS is rated in volt-amps (VA) which is the total power it can handle and the time it can run the server, usually the time required for the operating system to close all running applications, gracefully shut itself down, and turn off the server.\par }

• Question 73:

  Which statements are correct about mixing drives with different sizes and speeds within an array? (Select two)

  A. Performance may be degraded.

  B. Performance of the fastest disk is provided.

  C. Capacity is wasted.

  D. There is no impact on the capacity usage of each disk.

  E. Usage of hot spare disks is not necessary.

  Correct Answer: AC

This configuration can result in wasted space and degraded performance, but it will work.\par }

• Question 74:

  Which statements are true about out-of-band network management? (Select three)

  A. TELNET or SSH protocols are used to manage the devices.

  B. TCP/IP and SMTP protocols are used to manage the devices.

  C. A seperate network is maintanced for management access and control data.

  D. Control and management data share the same network as the data being processed.

  E. Network ports are not used for device management.

  Correct Answer: ACE

It can be invaluable in emergency situations to return a server with a non-responding operating system to service until it can be managed again with in-band tools. Out-of-band management is less secure because it depends on the configurations of the other out-of-band components in the mix.\par Telnet or SSH are used to manage the devices. Network ports are not used for device management. A separate network is maintained for management access and control data.\par }

• Question 75:

  Your RAID 5 array on a Smart Array sustains a drive failure. A hot spare replaces the failed drive and rebuilds successfully. After replacing the failed drive with a new drive, what happens next?

  A. The spare drive replicates its data to the new drive and both work as a mirror until you evict the spare drive.

  B. The new drive stays offline until you assign it to the array, at which point it automatically takes the place of the spare drive.

  C. The new drive re-assumes its place in the RAID set and after data rebuild is complete, the drive that was the spare once again becomes the hot spare drive.

  D. The new drive becomes a spare drive and you must go to the ACU to remove the old space drive and then re-add the new drive to the array.

  Correct Answer: C

  {\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fnil\fcharset0 MS Shell Dlg 2;}} \viewkind4\uc1\pard\lang2052\f0\fs17 Industry Standard Architecture - Student Guide 1 - Page 269\par As soon as the failed drive is replaced,

  data is automatically rebuilt on the new drive. After data has been completely rebuilt on the new drive, the online spare returns to its role as an online spare drive.

  This avoids roaming online spare drives.\par

• Question 76:

  Which RAID level offers disk mirroring and data striping without parity?

  A. RAID 1+0

  B. RAID 5+0

  C. RAID 6+0

  D. RAID ADG

  Correct Answer: A

• Question 77:

  You are integrating a RAID array for mixed read/write applications. What should you do with striping to achieve optimal performance?

  A. Accept the default stripe size.

  B. Disable striping.

  C. Increase the stripe size.

  D. Decrease the strip size.

  Correct Answer: A

• Question 78:

  Your customer wants to guard against the simultaneous loss of any two disk drives in his RAID array. Which RAID level can be used to accomplish this?

  A. RAID 1

  B. RAID 3

  C. RAID 5

  D. RAID 6

  Correct Answer: D

  {\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fnil\fcharset0 MS Shell Dlg 2;}} \viewkind4\uc1\pard\lang2052\f0\fs17 Industry Standard Architecture - Student Guide 1 - Page 261\par RAID 6 ?Advanced data guarding\par RAID 6, also known as Advanced Data Guarding (ADG), provides high fault tolerance. It distributes two sets of parity data protecting against two drive failures.\par As the graphic shows, parity (P) is written twice for each piece of data (D). These two sets are different, and each set occupies a capacity equivalent to that of one of the constituent drives.\par }

• Question 79:

  Which statement is true about a JBOD?

  A. It is configured as a RAID 0 by default.

  B. It contains a minumum of one hot spare disk.

  C. It offers no data redundancy or striping

  D. It is connected to a minimum of two hosts by default.

  Correct Answer: C

  {\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fnil\fcharset0 MS Shell Dlg 2;}} \viewkind4\uc1\pard\lang2052\f0\fs17 Industry Standard Architecture - Student Guide 1 - Page 250\par Just a bunch of disks (JBOD) is a storage option that connects one or more standalone disk drives to a RAID controller or other drive controller of a server. This option increases capacity and is used for noncritical business data.\par The JBOD drive does not become part of a RAID array, but it is made available to the server on the same interconnect bus as the other devices controlled by the RAID controller. The JBOD disk drive has no data redundancy or striping.\par }

• Question 80:

  What are two types of backbone SAN topologies? (Select two)

  A. fat tree

  B. meshed

  C. skinny tree

  D. cascaded

  E. ring

  Correct Answer: AC

  {\rtf1\ansi\ansicpg936\deff0\deflang1033\deflangfe2052{\fonttbl{\f0\fnil\fcharset0 MS Shell Dlg 2;}} \viewkind4\uc1\pard\lang2052\f0\fs17 Industry Standard Architecture - Student Guide 1 - Page 295\par Fat trees and skinny trees are two types of backbone SAN topologies. The main difference between fat and skinny trees is the number of ISLs used to connect the edge switches to the backbone switches. The number of ISLs subtracts from the number of end ports and affects the total number of switches needed for a particular configuration. Fat trees use half the number of edge switch ports as ISL connections; skinny trees use less than half.\par }
