In Filesystems, what does FAT stand for?
File Allocation Table
Raid 0 allows for double speed and double storage requiring only one disk.
False
In a RAID 0 system, data are split up into blocks that get written across all the drives in the array. By using multiple disks (at least 2) at the same time, this offers fast read and write speeds. All storage capacity can be fully used with no overhead. The downside to RAID 0 is that it is NOT redundant, the loss of any individual disk will cause complete data loss. Thus, it is not recommended to use unless the data has no value to you.
A SAN (Storage Area Network) is usually mapped in a way that makes it seem like a locally attached device.
True
To a client OS, a SAN typically appears as a disk and exists as its own separate network of storage devices, while NAS appears as a file server
Select the storage types that are most typically found on networks.
Points will be deducted if you choose an incorrect answer(s).
- NAS (Network Attached Storage)
- SAN (Storage Area Network)
Network Access Storage and Storage Area Networks are typically found on Networks as Storage solutions.
While restoring a backup for a client you see files that seem to indicate illegal activity, what should you do?
Alert the relevant authorities.
Persistent storage is also referred to as non-volatile storage.
True
Persistent storage is any data storage device that retains data after power to that device is shut off. It is also sometimes referred to as non-volatile storage. Magnetic media, such as hard disk drives and tape are common types of persistent storage, as are the various forms of optical media such as DVD.
TCP/IP stands for Transmission Control Protocol and Internet Protocol
True
TCP/IP does stand for Transmission Control Protocol and Internet Protocol
IP addresses allow computers to communicate with other computers on the same local network.
True
On a computer network, all devices that are connected to the same local network can talk directly with each other, as long as they have IP addresses that belong to the same IP network. If the computers belong to different IP networks then they have to communicate with each other via a router
While working on a client’s workstation, you accidentally open a very personal file. What should happen next?
Close the file and report it to the client
Can a HDD have more than one platter?
Yes
Yes, hard disk drives can have more than one platter
Which of the following is a valid encoding format?
UTF-8
UTF-8 (8-bit Unicode Transformation Format) is a variable-width character encoding capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte (8-bit) code units.
Hyper-Threading is always better than multiple CPU-Cores?
False
While the operating system sees two CPUs for each core, the actual CPU hardware only has a single set of execution resources for each core. … Hyper-threading is no substitute for additional cores, but a dual-core CPU with hyper-threading should perform better than a dual-core CPU without hyper-threading.
What Network “gave birth” to the Internet?
ARPANET
A NAS is mainly used over the network.
True
A NAS system is a storage device connected to a network that allows storage and retrieval of data from a centralized location for authorized network users and heterogeneous clients
Select the correct Hexidecimal values.
Points will be deducted if you choose an incorrect answer(s).
- 263A
- 270C
Which of the following Linux file systems use a journaling system?
Points will be deducted if you choose an incorrect answer(s).
- Ext3
- Ext4
Ext 3 and Ext 4 supports journaling.
IP addresses allow computers to communicate with other computers on the same local network.
True
On a computer network, all devices that are connected to the same local network can talk directly with each other, as long as they have IP addresses that belong to the same IP network. If the computers belong to different IP networks then they have to communicate with each other via a router
