Which service can you use on your network to automatically assign IP addresses to hosts and to help prevent the same address from being assigned to two different hosts?
DHCP You can use the Dynamic Host Configuration Protocol (DHCP) to set up a DHCP server that will assign IP addresses automatically to network hosts. DHCP servers will not assign the same IP address to two different hosts. ICMP is chiefly used by networked computers' operating systems to send error messages. The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite. The Internet Group Management Protocol (IGMP) is a communications protocol used to manage the membership of Internet Protocol multicast groups
You want to implement name resolution on the Linux workstations in your company. Which protocol will you use to do this?
DNS You can use DNS name resolution for Linux workstations (as well as for most other operating systems). NetBIOS name resolution (LMHOSTS files or WINS) is typically used on Windows-based networks. The Lmhosts file is a local text file that maps Internet Protocol (IP) addresses to NetBIOS names of remote servers with which you want to communicate over the TCP/IP protocol. A WINS server address is only needed if you have older Windows clients on multiple networks. Network Time Protocol (NTP) is a means of transmitting time signals over a computer network. Simple Mail Transfer Protocol (SMTP) is used to route electronic mail through the internetwork. E-mail applications provide the interface to communicate with SMTP or mail servers.

You have a computer with three hard disks. A RAID 0 volume uses space on Disk 1 and Disk 2. A RAID 1 volume uses space on Disk 2 and Disk 3. Disk 2 fails. Which of the following is true?
Data on the RAID 1 volume is accessible; data on the RAID 0 volume is not. In this scenario, Disk 2 is shared between both volumes. If disk 2 fails, the RAID 1 volume is still accessible because RAID 1 (mirrored) volumes can sustain a loss of single disk. The data on the RAID 0 volume is not accessible. RAID 0 uses striping, which distributes the data evenly between multiple disks. If a single disk fails, the entire volume is lost.
Windows 10 features a storage solution call Storage Spaces. What is the name of the Storage Spaces feature that allows to allocate space for redundant information using options that include two-way mirroring, three-way mirroring, and parity?
Data resiliency Storage spaces can include data resiliency. Choosing an option that provides resiliency requires you to allocate space for redundant information. The options for storage spaces data resiliency include: -Simple, which does not provide redundancy. This option simply adds space from the storage pool to the storage space. When you select the Simple option, all of the data in the storage space is lost if one of the drives fails. -Two-way mirror requires at least two storage devices. The data is written to two devices. Two-way mirror requires twice as much device space as the amount of storage allocated to the storage space. This option protects you from a single storage device failure. -Three-way mirror requires at least five storage devices. The data is written to the three storage devices. This option provides redundancy for the data if two storage devices fail at one time. -Parity requires that you have at least three storage devices. This option uses parity information to reconstruct data if one of the storage devices fails. Parity uses less space for redundancy than the mirror options, but performance is not as good as the mirror options if a device failure occurs. Parity requires only 50 percent more redundancy space than storage space.
Which of the following is inserted in an AMR slot to provide sound functions?

You have an existing computer running Windows & Enterprise. You want to configure a RAID 1 array in the computer. You install two new SATA drives, then use the RAID controller integrated in the motherboard to define a RAID 1 array using them. When you boot the computer, Windows does not show the logical RAID drive. What should you do?
Install the drivers for the RAID controller. You must install the RAID driver so that Windows recognizes arrays created by the mother board RAID utility. Without the driver, Windows will not be able to see the logical drive defined by the array. When you define the array, you configure the BIOS to use RAID as the SATA type. If you had not completed this step, you would not be able to run the RAID configuration utility. Use AHCI to configure SATA drives to support hot-swapping.

Windows 10 features a storage solution called Storage Spaces. When you configure Storage Spaces you can include information redundancy with a feature called data resiliency. Match the types of data resiliency on the left with the appropriate descriptions on the right. Each type of data resiliency may be used once, more than once, or not at all.
Requires that you have at least three storage devices - Parity Requires at least five storage devices - Three-way mirror Does not provide redundancy - Simple Protects you from a single storage device failure - Two-way mirror Requires at least two storage devices - Two-way mirror Allows you to reconstruct data if one of the storage devices fails - Parity Protects your data if two storage devices fail at one time - Three-way mirror Storage spaces can include data resiliency. Choosing an option that provides resiliency requires you to allocate space for redundant information. The options for storage spaces data resiliency include: -Simple, which does not provide redundancy. This option simply adds space from the storage pool to the storage space. When you select the Simple option, all of the data in the storage space is lost if one of the drives fails. -Two-way mirror requires at least two storage devices. The data is written to two devices. Two-way mirror requires twice as much device space as the amount of storage allocated to the storage space. This option protects you from a single storage device failure. -Three-way mirror requires at least five storage devices. The data is written to the three storage devices. This option provides redundancy for the data if two storage devices fail at one time. -Parity requires that you have at least three storage devices. This option uses parity information to reconstruct data if one of the storage devices fails. Parity uses less space for redundancy than the mirror options, but performance is not as good as the mirror options if a device failure occurs. Parity requires only 50 percent more redundancy space than storage space.

Your computer currently uses a 5,400 RPM hard disk. You want to improve your computer's overall performance by optimizing you hard disk performance. Which of the following would be the most effective means for optimizing your hard disk performance? (Select two.)
Upgrade your hard disk interface to SATA 3 Upgrade to a 10,000 RPM hard disk Upgrading to a 10,000 RPM hard disk and upgrading to a SATA 3 disk interface are the two most effective steps you can take to improve your computer's overall performance. The 7,200 RPM hard disk is not the fasted hard disk option. At 600 Mbps, the SATA 3 disk interface is twice as fast as the SATA 2 interface. Although hard disk drives are not capable of sending data at full 600 Mbps, they can go faster than the SATA 2 interface allows. Implementing RAID 0 does improve hard disk performance, but it requires a minimum of two disks. Adding another hard disk while keeping your current 5,400 RPM disk would not improve your hard disk performance as much as upgrading to 10,000 RPM hard disk with a SATA 3 disk interface.
