Q

Serial Advanced Technology Attachment (SATA)

A

Serial ATA is the most widely used interface for hard disks on desktop and laptop computers. It uses a 7-pin data connector with one device per port. There are three SATA standards specifying bandwidths of 1.5 Gb/s, 3 Gb/s, and 6 Gb/s respectively. SATA drives also use a new 15-pin power connector, though adapters for the old style 4-pin Molex connectors are available. External drives are also supported via the eSATA interface.

Q

A video production company uses removable media to transport multimedia files to partner and customer sites. Often, the media has to be prepared with only very short notice. In the past, the time taken to transfer files from the development workstations has resulted in delays and missed appointments. To mitigate this issue, the company has procured USB 3.2 Gen 2x2 storage devices and Windows PC workstation expansion cards. The devices and expansion cards support multiple USB hardware port types. Which of the following adapter cables will enable the devices to take full advantage of the highest transfer rate?

Type A to Type A with USB 3 compatibility (denoted by a blue tab)
Type B Micro to Type A with USB 3 compatibility (denoted by a blue tab)
Lightning to Type A
Type C to Type C

A

Type C to Type C

Q

A firm has asked a forensics expert to review the contents of an older SCSI system. However, before acquiring the system, the components were separated to obscure the information on the system. What should the forensics expert do to the first device on the SCSI bus?

A

Terminate.

The forensic expert must terminate the first and last devices on a Small Computer System Interface (SCSI) bus. Termination may be enabled internally on the device by switching or physically connecting a terminator pack to a device or the host adapter.

Q

A server administrator for a major transportation company is facing a crisis where ransomware has taken over and destroyed the primary and backup locations. Luckily there was an unaffected offline domain controller in a remote country where the administrator needed to fly to immediately and back up the contents via a USB hard drive. The administrator uses a hard drive running USB 3.2 that supports 10 Gbps speeds but must ensure the legacy server can support connectors. Which of the following are supported connectors? (Select all that apply.)

USB-C

USB-A

USB-B

USB Micro

A

USB-C

USB-A

21
Q

A help desk analyst is replacing an internal hard drive on a desktop. A technician had previously removed the hard drive, so the analyst did not have a chance to map which cable should go where. Which cable will provide power in a modern SATA setup?

A

A separate 15-pin serial advanced technology attachment (SATA) power connector connects the device to the PC’s power supply.

22
Q

A helpdesk engineer runs cabling at a construction site. The site needs to achieve 100 Mbps, but the manager wants them to use the oldest cabling first to get rid of it. Which cabling should the engineer use?

A

Cat 5 cable supports the older 100 Mbps Fast Ethernet standard. It is no longer commercially available. A technician will probably need to rewire the network cabled with Cat 5 to support Gigabit Ethernet.

23
Q

An organization has asked a security analyst to review the contents of an external drive to see if the drive is reusable or if the organization needs to destroy it. However, the drive does not have a cable that connects to a USB. After finding an older computer that supports the cable type, it still does not seem to connect. The analyst notices that there appears to be a cable for what looks like power to the device. What type of cable should the analyst try using?

A

There is an external serial advanced technology attachment (eSATA) standard for the attachment of peripheral drives. eSATAp is a nonstandard powered port used by some vendors.
