Question 1

What is the maximum number of nodes supported by server clustering in Windows Server 2008?
A)4
B)8
C)16
D)32

Accepted Answer

Server clustering in Windows Server 2008 supports a maximum of 16 nodes.
Key Takeaway: A server cluster is a group of independent servers working together as a single system to provide a high availability of services for clients. When one or some of the servers fail, resources are redirected and the workload is redistributed to the working servers in the cluster. Clustering is used for applications that have long-running in-memory state or frequently updated data. The individual servers in a cluster are called nodes. The maximum number of nodes varies depending on the version of the operating system. For example, Windows Server 2003 supports a maximum of 8 nodes, whereas the newer Windows Server 2008 supports up to 16 nodes.

Question 2

What is the maximum number of nodes supported by Network Load Balancing?
A)32
B)4
C)8
D)16

Accepted Answer

Network Load Balancing supports a maximum of 32 nodes.
Key Takeaway: Network Load Balancing Services, or NLBS, is a proprietary Microsoft implementation of clustering and load balancing that is intended to provide high availability, reliability, and scalability. It is intended for applications with relatively small data sets that do not change frequently and do not have long-running in-memory states. An interesting feature with NLBS is that all servers in a cluster examine each other with a heartbeat signal. This avoids a single point of failure. The maximum number of nodes supported with NLB is 32.

Question 3

David's server is not able to detect a hot-plug NIC that is plugged in as a replacement. Which of the following specifies the first troubleshooting step to perform?
A)Check if the hot-plug PCI slot has been reactivated.
B)Use the Windows configuration tools to define the NIC as a software.
C)Replace the NIC.
D)Configure the NIC to transmit both LAN and storage communications.

Accepted Answer

The troubleshooting step to be performed is to check if the hot-plug PCI slot has been reactivated.
Key Takeaway: The PCI hot-plug specification defines the requirements for adapter cards, system platforms, and system software to enable the insertion and removal of PCI adapter cards without turning off the platform or rebooting the operating system. This specification is a supplement to the Conventional PCI Specification and is applicable to those cards, platforms, and operating systems that need higher availability.

Question 4

Which of the following is the easiest way to distinguish an NLX motherboard?
A)It has both IDD and SATA sockets.
B)It has 3 memory slots.
C)It has dual processor slots.
D)The expansion cards connect to the riser card.

Accepted Answer

The best way to detect an NLX motherboard is the riser card that accommodates the expansion cards.
Key Takeaway: Motherboard form factors are defined by their size and the functionalities included. Of them, NLX is an industry-wide open specification that is a space-saving computer motherboard form factor. It rests on rails and simply slides out without any screws to unscrew or card to remove. The motherboard plugs into a riser card that sits at a 90-degree angle from the motherboard. A riser card is an expansion card that physically extends a slot for more expansion cards. When the motherboard is removed, the riser card stays in place. The riser card allows two to four expansion cards to be plugged in. These expansion cards sit parallel to the motherboard.

Question 5

Which of the following components are not integrated on a motherboard?
A)Network card
B)Video
C)Audio
D)Power supply

Accepted Answer

Power supply is a not integrated on a motherboard.
Key Takeaway: Modern motherboards integrate most of the necessary functionalities like audio, video, and network card. This eliminates the need to install different expansion cards for these components. Components such as hard drive, RAM, processor, and power supply are never integrated on a motherboard.

Question 6

David is troubleshooting his computer, which does not start up. The issue occurs immediately after the system fan powers up. Which of the following could be causing this problem?
A)Processor
B)Hard drive
C)Motherboard
D)Monitor

Accepted Answer

If the issue occurs after the fan powers up, the processor is causing this issue.
Key Takeaway: When a system starts, the power supply fan is activated. Next, the keyboard lights flash, indicating that the system components are reset. Now the processor starts. You should always check if the configured voltage settings and speed settings match the CPU type and speed.

Question 7

John is encountering a startup issue right after the POST beep sound and before the operating system UI loads. Which of the following is the most likely of the issue?
A)A mismatch between the hardware components and the CMOS configuration
B)A mismatch between API configuration parameters and the System hardware configuration
C)Operating system is outdated
D)A missing or corrupt operating system file

Accepted Answer

The cause of this error is a missing or corrupt operating system file.
Key Takeaway: Many times you may encounter an issue where the POST is successful, but the operating system UI does not load. When you encounter this error, this means that you have an issue with your operating system. The most common cause is a missing or corrupt boot file, a boot drive issue, or a missing /corrupt operating system file.

Question 8

Which of the following should happen in a boot process after the BIOS setup is displayed on the monitor?
A)Power supply switches ON
B)FDD light appears
C)System gives a count of system memory
D)Keyboard lights start flashing

Accepted Answer

During a boot process, the system displays a count of the system memory after the BIOS setup is displayed.
Key Takeaway: The steps involved in the boot process are power supply activation, keyboard lights flashing, BIOS setup displayed on the screen, and the system giving out a count of the memory installed. Once all this is complete, control is transferred to the operating system and the boot process is complete.

Question 9

David has just installed the Wake-On-LAN card on his server. He tries to boot the remote servers and is unable to do so. Which of the following packets could be the cause of the issue?
A)Magic packet
B)SNMP packet
C)TCP/IP packet
D)IP packet

Accepted Answer

Magic packet is causing an issue.
Key Takeaway: Wake-on-LAN is an Ethernet computer networking standard that allows a computer to be turned on or woken up by a network message. The computer to be woken up is shut down with power reserved for the network card. The network card listens for a specific packet containing its MAC address, called the magic packet, broadcast on the broadcast address for that particular subnet. Once it receives this packet, it checks the packet for the correct information. If the magic packet is valid, the network card takes the computer out of hibernation or standby and starts it up.

Question 10

You have just installed an additional RAM module on your server. Although the server successfully boots to the NOS, not all the RAM is being recognized. Which of the following could be the cause of this issue?
A)Latest patches for the NOS are not installed
B)Motherboard BIOS is not updated
C)Memory is not configured in the CMOS
D)Incompatible memory

Accepted Answer

If the system is not showing all of the memory that is installed on the computer, then memory is incompatible.
Key Takeaway: Prior to installing RAM on a server, it needs to be checked for hardware and the NOS compatibility. If this step is not performed and incompatible memory is installed, the system will not count this particular memory module as a part of the resource available on the computer. Updating the BIOS does not alter the physical RAM requirements of the board.

Question 11

David has installed multiple processors on his computer. However, the system recognizes only one processor. Which of the following could be the possible cause of this issue?
A)Processor speed mismatch
B)Additional VRMs are not used
C)Empty processor slots do not have terminator resistor packs.
D)The OS is not configured to use multiple processors.

Accepted Answer

Multiple processers are not recognized on the OS because the OS is not configured to use multiple processors.
Key Takeaway: After installing multiple processors on a system with multiple processor slots, the system must be configured to run using SMP. Otherwise, the system continues to function using a single processor. Symmetric Multi-processing, or SMP, is a multiprocessor architecture that supports two or more identical processors to connect to a single shared main memory. It allows a processor to work on any task, irrespective of where the data for that task is located in memory. It is also used to balance the workload efficiently between multiple processors on the system.

Question 12

John is administering a set of servers in his organization. One of the drives in a RAID-5 disk array fails. From a business standpoint, John cannot shut down the server to replace the hard drive. What else can he do to fix this issue?
A)Update the driver for the bad hard drive.
B)Swap the drive through the hot-swapping method.
C)Re-install the driver for the bad hard drive.
D)Shut down the server and swap the hard drive.

Accepted Answer

John should use hot-swapping and swap the drive to fix this issue.
Key Takeaway: Hot-swap technology allows a user to insert or remove various PCI cards and hard drives on the fly. These can be replaced without having to shut down the system. The system that supports hot-swapping should be able to modify its operation for the changed configuration, either automatically or by user intervention. The electrical and mechanical connections associated with hot-swapping must be designed in such a way that neither the equipment nor the user can be harmed during the process.

Question 13

Janet has been using her computer for over a year now. Currently, she is facing a problem with an incorrect date and time set on her computer. She has tried to rectify it several times, but is not able to fix it. Which of the following could fix her problem?
A)Replacing the CMOS battery
B)Replacing the motherboard
C)Replacing the video card
D)Re-installing the operating system

Accepted Answer

To fix the problem with an incorrect date and time on her computer, Janet should replace her CMOS battery.
Key Takeaway: The CMOS battery on the system board supplies power to the CMOS chip, even when the computer is turned off. This CMOS chip contains information about the system configuration, which includes hard disk settings, floppy drive settings, date and time, and the order in which the computer will look for bootable disks. An indication of incorrect time and date is due to the CMOS battery not being able to supply optimal power to the CMOS chip. So this battery must be replaced before it goes dead.

Question 14

You are trying to troubleshoot a monitor that has a dead screen. The brightness and contrast controls are turned up and you now want to check if the monitor display is working. What should you do?
A)Clean the screen with a dry cloth.
B)Switch ON the computer and feel the static on the screen.
C)Clean the screen with a wet cloth.
D)Switch OFF and then switch ON the monitor.

Accepted Answer

To verify if the monitor is working, you should switch ON the computer and try to feel the static on the screen.
Key Takeaway: Monitors usually contain a high voltage setup. This high voltage setup tends to leave a static charge on the screen. This static charge can be felt by placing the back of your hand a couple of centimeters away from the monitor screen. If you can feel the static it means the monitor is working. If you cannot feel the static, the monitor is dead and needs to be replaced or repaired.

Question 15

John is managing a server that has four internal hard drives. POST only indicates that two HDDs are installed. Which of the following could be the most likely cause of this issue?
A)Two of the four are SCSI hard drives.
B)Disks are configured in two separate RAID arrays.
C)Disks are configured in a RAID 1 mirrored array.
D)Disks are configured in a RAID 0 striped array.

Accepted Answer

Although John has configured four internal drives, two of these are SCSI hard drives.
Key Takeaway: SCSI hard drives are not detected during a boot process. Only ATA or SATA drives are. Although SCSI and RAID controllers are mounted during the POST, the disk drive volumes are loaded later.

Question 16

Which of the following is the safest location for storing a Disaster Recovery Plan?
A)Offsite, on backup tapes
B)Onsite and offsite, on backup tapes
C)Onsite, on backup tapes
D)Onsite and offsite, on zip drives

Accepted Answer

DRP documentation should be stored both onsite and offsite, on backup tapes.
Key Takeaway: Storing the DRP documentation in a place that is easily accessible is very important. Additionally, it should also be stored in a place that is not affected by a disaster, an offsite recovery hub. Storing it in both these places ensure that is always available and safe from any disaster. This way it can be used efficiently at times of disaster.

Question 17

David is a network administrator for his organization. The organization has three servers and a domain. After performing an upgrade on the server that functions as the DHCP server, David reboots the server. He receives an error message that states "DHCP Service has failed to start." Where should he check for more information on this error?
A)F1-based help on Windows OS
B)System log on the Event Viewer
C)Application log on the Event Viewer
D)Microsoft's support website

Accepted Answer

David should check for more information on this error in System log on the Event Viewer.
Key Takeaway: The error messages that pop up when a system boots will log more information in the System log of the Event Viewer. David should go to Administrative Tools > Event Viewer > System logs first to get more information on this error. If he does not find any useful information in the System logs, he can move on to Microsoft's support site and use the Event ID to get more information.

Question 18

You purchase a new RAM chip and want to install it on your server. You test the chip on an identical test server and find that it is compatible. However when you place the chip on the actual server, the new memory is not recognized. What is the most likely cause of the RAM not being recognized on the actual server?
A)The actual server's motherboard already has the maximum amount of RAM supported.
B)You must install new RAM chips in pairs, not individually.
C)The RAM is faulty.
D)The RAM is not supported on the actual server.

Accepted Answer

The actual server's motherboard already has the maximum amount of RAM supported.
Key Takeaway: Motherboards are usually shipped with documentation that mentions the maximum amount of RAM, processor speed, and hard drive space supported. It is important to check and compare the documentation and the system information before starting out to buy additional hardware for your server. Motherboards do not support components that have a higher rating than the ones mentioned in the documentation.

Question 19

Which of the following does an ESD wrist strap or mat contain that helps remove ESD charges safely?
A)Resistor
B)Inductor
C)Diode
D)Capacitor

Accepted Answer

An ESD wrist strap or mat contains a resistor.
Key Takeaway: An ESD wrist strap is a safety device used to channel static electricity to a proper ground when you are handling sensitive computer equipment. Electrostatic discharge can cause device damage when a release of stored static electricity travels from a person's body into a conductor at a different potential. The ESD wrist strap safely channels the static electricity to a proper ground by bleeding the charge away from you and the computer to a ground source using a resistor.

Question 20

What is the minimum number of steps required to create a disaster recovery plan?
A)Five
B)Seven
C)Six
D)Eight

Accepted Answer

The minimum number of steps required to create a disaster recovery plan is six.
Key Takeaway: The six steps required to create a disaster recovery plan are: develop the Business Contingency Planning Policy and business process priorities; conduct a risk assessment; conduct the business impact analysis; develop business continuity; recovery strategies, business continuity plans, conduct awareness, testing, and training of the DRP; and conduct disaster recovery plan maintenance and exercise.
