CompTIA-2
| Question | Answer |
|---|---|
| Which IEEE standard implements PoE+? | IEEE 802.3at |
| The IEEE 802.3bt standard implements: | PoE++, 4PPoE |
| A network segment utilizing only this type of device is the most prone to network performance degradation due to large number of network collisions. | Hub |
| The disadvantage from using this device results from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports which has a negative impact on network performance. | Hub |
| Which of the following answers refer to the characteristic features of cable modems? (Select 3 answers) | Cabling that carries TV signals, Coaxial Cabling, Shared bandwidth |
| Which of the answers listed below apply to DSL modems? (Select 3 answers) | Twisted-pair copper cabling, Telephone lines, Dedicated bandwidth |
| Which of the answers listed below refers to a technology designed to simplify network infrastructure management? | SDN |
| The functionality of a Network Interface Card (NIC) can be checked by pinging: (Select 3 answers) | localhost, ::1, 127.0.0.1 |
| A type of network connecting computers within a small geographical area such as a building or group of buildings is called: | LAN |
| A type of limited-range computer network used for data transmission among various types of personal devices is known as: | PAN |
| A dedicated local network consisting of devices providing data access is known as: | SAN |
| SCSI ID | Identifies physical device on a SCSI chain |
| Which of the answers listed below refers to a method for identifying logical partitions on a SCSI drive? | LUN |
| Which of the following requires termination? | SCSI chain |
| What is the maximum allowable number of devices that can be attached to a parallel SCSI bus? | 16 devices |
| Which of the answers listed below refer to the characteristic features of SAS? (Select 3 answers) | Serial interface, Point-to-point connection, does not require bus termination |
| Which of the following answers list(s) example(s) of hot-swappable drives? (Select all that apply) | SATA drive, eSATA drive |
| What is the maximum number of devices that can be attached to a PC through a single PATA cable? | 2 |
| Which of the following answers refers to the maximum rpm value available in modern HDDs? | 15000 RPM |
| Which of the answers listed below refer to storage media device interfaces for SSDs? (Select 3 answers) | NVMe, SATA, PCIe |
| A logical device interface used for accessing non-volatile memory storage devices attached via PCIe is known as: | NVMe |
| Which of the following answers refer to SSD form factors? (Select 2 answers) | M.2, mSATA |
| Which of the answers listed below refers to an older, portable device SSD form factor superseded by M.2? | mSATA |
| Hardware RAID Level 0: (Select 3 answers) | is also known as disk striping, Decreases reliability (failure of any disk in the array destroys the entire array), Is suitable for systems where performance has higher priority than fault tolerance |
| Hardware RAID Level 1: (Select 3 answers) | Requires at least 2 drives to implement, Is also referred to as disk mirroring, Offers improved reliability by creating identical data sets on each drive (failure of one drive does not destroy the array as each drive contains identical copy of the data) |
| Hardware RAID Level 5: (Select 2 answers) | Requires at least 3 drives to implement, Offers increased performance and fault tolerance (single drive failure does not destroy the array and lost data can be re-created by the remaining drives) ( Your answer) |
| Which of the answers listed below refer(s) to (a) nested RAID level(s)? (Select all that apply) | RAID 1+0, RAID 10 |
| Hardware RAID Level 10 requires a minimum of: | 4 drives |
| Which type of RAID creates a striped set from a series of mirrored drives? | RAID 1+0 |
| Examples of flash memory card formats include: (Select all that apply) | SD, CompactFlash, microSD, miniSD, xD |
| Which of the following is a file system designed for optical media? | CDFS |
| Due to size restrictions and compact nature of laptops devices, this type of storage media becomes less commonly found on new laptops. | Optical drives |
| Which of the following dedicated expansion slots/ports on the PC motherboard enable(s) connecting an M.2 device? (Select all that apply) | B key slot, M key slot, B+M key slot |
| Which state of the HDD LED light typically indicates the drive's normal operation? | Intermittent flashing |
| Restoring a RAID array after physical failure of one of the drives typically requires a very simple fix, which is the replacement of a bad drive. This solution will work for most of the RAID configurations except: | RAID 0 |
| Which of the following metrics might be of help in diagnosing the declining performance of a storage drive? | IOPS |
