Question: A new free-standing rack has just been delivered to a technician. The rack has been moved into the server room, to its designated location. How should the technician proceed with installing the rack mount components? A: Install heavy components at the top of the rack. B: Install heavy components at the bottom of the rack. C: Install the components according to the manufacturer's documentation. D: Install the components according to the priority of each component. Explanation: The manufacturer's documentation will provide the technician with the proper instructions on how to load the components into the rack safely and properly. Errata: Answer C is the correct answer, however, page 34 of the text gives Answer B. In most instances, however, manufacturer’s documentation will instruct you to place heavier components at the bottom of the rack, so both could be correct in many cases.

Question: A new processor has just arrived to be added to an existing server. What should the technician verify before proceeding with the installation? Answer 1: Cache Answer 2: Stepping Answer 3: Brand name Answer 4: Speed Explanation: The stepping, or revision of the new processor, should be identical to the existing one. Errata: The answer is A, B & C. If the processor is a AMD, Sparq, PowerPC, or even Itanium, it typically will not if your runnning an Intel xeon processor. Speed and cache size are also important if not more/most important. If you install different speed processors and if the L1 cache is different, the server may not boot up. You can sometimes "get away with" processors of stepping differences off by 1.

Question: A technician is installing an 8-bit SCSI drive on an Ultra2 SCSI system. How should this system be configured? A: Terminate the 16-bit bus, then add the 8-bit device on the end. B: The 8-bit device should be on its own bus. C: Ensure there is a 16-bit device terminating the bus, and the 8-bit device can be placed anywhere before that device. D: The 8-bit SCSI drive will need a 16-bit terminator. Explanation: An Ultra2 SCSI bus must be terminated with a 16-bit device. The 8-bit device can be installed anywhere in the middle of the chain. Errata: Ultra2 SCSI is also 8 bit, not 16 bit. An Ultra2 wide SCSI is 16 bit. The question should have read: “A technician is installing an 8-bit SCSI drive on an Ultra2 wide SCSI system. How should this system be configured?” The correct answer would then be C.

Question: A network administrator uses a differential tape backup plan. A user requires a certain file to be restored from the Wednesday tape. How many tapes in total will be needed for the restore operation? A: 1 B: 2 C: 3 D: 4 Explanation: In a differential scheme, the backup program backs up all data that has changed since the last full backup. To restore the file, you would only need the one tape from Wednesday. Errata: The answer given for this question is Answer A, but the answer is B, 2 tapes. In order to restore a file from a differential backup the full backup and that day’s differential backup are needed. See page 479 of Server+ Certification Bible for further details.

Question: You are about to install a new server in the computer. Which of the following is the most important when verifying a power source? Choose all that apply. A: DC voltage B: Proper grounding C: Amperage D: UPS capacity Explanation: DC voltage, proper grounding, and Amperage are the most important items to check regarding power sources. Answer D is incorrect because it has no impact on the installation of the server. Errata: The first sentence in the question should be “You are about to install a new server in the computer room.” There is also a typo in Answer A. It should read “AC voltage”, not “DC voltage”. The explanation should also read: “AC voltage, proper….”, not “DC voltage”. The correct answers are A, B, and C.

Question: Your company experienced a complete drive failure on one of the file servers and lost all the user data that it contained. Upon your recommendation, the company agreed to modify the RAID levels on all the file servers. The servers are currently using RAID Answer 1: The configuration will not create redundancy. Answer 2: The configuration will create redundancy and improve disk read performance. Answer 3: The configuration will create redundancy. Answer 4: It will only improve disk read/write performance. Explanation: RAID 5 requires a minimum of three drives, and does not create data redundancy. RAID 5 stores parity information but no redundant data, and the parity information is used to reconstruct the data in the event of a drive failure. Errata: A or D is the correct answer for this question. As per your explanation of the answer. RAID 5 does not create redundancy.

Question: Which type of SCSI signaling uses a balanced approach? A: Single-ended Devices B: Double-ended Devices C: Low voltage differential D: Differential signaling Explanation: Differential signaling or high voltage differential SCSI uses a balanced approach that requires twice as many wires in the cable. Differential allows for a bus length of up to 25 meters. Errata: Answer C, low voltage differential, should also be a correct answer. Low voltage differential also uses a balanced approach and is referred to as differential signaling.

Question: A hot spare refers to: Answer 1: A standby hard disk drive not included as a part of the RAID array. Answer 2: A standby hard disk drive included as a part of the RAID array. Answer 3: A special hard disk drive than can be installed and removed from a server without interrupting its regular operations. Answer 4: A special hard disk drive that can be installed to recover from a failover. Explanation: A hot spare refers to a standby hard disk drive that is not included as a part of the RAID array. When one of the drives in the array fails, the hot spare is automatically included in the array, providing maximum continued performance with minimal human i Errata: The correct answer is A but should have read "A standby drive that is installed as part of the array."

Question: You have ordered a SCSI card from a vendor for replacement. Which of the following should you provide the vendor to ensure that you get an identical card as replacement? (Choose the best option.) Answer 1: The model number of the card Answer 2: The serial number of the card Answer 3: The vendor part number of the card Answer 4: The vendor part of the CPU Explanation: The serial number of a component is the most reliable method of identification. Providing the vendor with the serial number ensures that you get the identical component. Errata: The answer should have been choice C, the vendor part number and the explanation should read "The vendor part number of a component is the most reliable method of identification. Providing the vendor with their vendor part number ensures that you get the identical component."

Question: A technician notices that the server is not responding. He also notices that the outer case of the server is very hot and hears a clicking sound. What could be the cause of the problem? Answer 1: Malfunctioning CPU fan Answer 2: Malfunctioning chassis fan Answer 3: Bad hard disk Answer 4: Bad power supply Explanation: The most probable cause is the malfunctioning of the CPU fan causing overheating. Errata: This question was poorly worded. Instead of clicking, the sound should have been described as a motor with bad bearings or that the tech hears no sound at all. Also, instead of the outer case being hot it should have been that the CPU was hot. With these changes to the question, Answer A would be the logical choice. Clicking sounds usually indicate hard drive problems. Hot outer cases usually mean bad chassis fans. So, these descriptions should not have been used in the question. Without the changes to the question, Answer B would be the best choice. If the CPU fan has gone out on the server, chances are the server will automatically shutdown, so would not be responding. Since the case is hot and the tech hears a clicking sound, this most likely would mean the CPU fan is fine but the servers chassis fan is not exchanging the hot air in the case with cooler air from the server room.

Question: Which of the following drive states indicate that the drive is recognized by the RAID controller and is a part of the array, but its role hasn't been defined? A: Defunct B: Online C: Ready D: Rebuilding Explanation: The online drive state indicates that the drive is recognized by the RAID controller and is a part of the array, but its role hasn't been defined. Errata: The correct answer is B, Online. The test incorrectly has C as the correct answer, which causes the test to incorrectly mark those who choose the correct answer B, as incorrect.

Question: Assigning a subnet mask to an IP address enables: (Choose the best answer.) Answer 1: Easy network administration Answer 2: Communication across networks Answer 3: Network security Answer 4: Internetworking Explanation: Assigning a subnet mask to an IP address divides the network into multiple logical networks by separating the network and host ID partitions of the IP address. This helps to simplify network administration. Errata: The correct Answer should be Choice B. A Subnet mask is is used to determine whether the packet destination is on a local network (in which case ARP is then used to locate the target MAC address) or on a remote network (in which case the current machine must send the packet to the "default route"). Choice A, "Easy network administration," would have been the right answer if the question involved DHCP.
