Which of the P6 RAID modes could increase write performance over a non-RAID filesystem by using concurrency?

Checkpointing is the process of creating a journal transaction before making any changes to the rest of the file system.

You use a log-based SSD to hold your data.  The SSD has 3 blocks with 10 pages per block.  Each page holds a single character.  The SSD has been used for a while and the current state of the SSD is shown below.  The diagram for the SSD contains the following items: FTL mapping logical pages to physical pages block numberpage number (2 lines)state of each page (valid, Erased, or invalid)data stored at each pagean indicator(+) if a page is currently live (has an entry in the FTL)Current State of SSD: FTL     1:  6   2: 10   5:  2   7:  1         8: 20   9:  4  12: 16  13:  9        15: 12  17: 17  18:  5  29: 13        19: 11  20: 14  21: 15  23:  3        24: 18  25:  0  27:  8  28:  7 Block 0          1          2          Page  0000000000 1111111111 2222222222       0123456789 0123456789 0123456789 State vvvvvvvvvv vvvvvvvvvv vEEEEEEEEE Data  Ih7tj3UYbK 34quFTEPXg H          Live  ++++++++++ +++++++++  +           Operations that the OS may perform are:write(Logical Address, Data) – storing the data at the logical address read(Logical Address) – reading the data from the logical address trim(Logical Address) – deleting the data from the logical address

Linux CFS picks the process with the smallest vruntime when scheduling.

Assuming we have the imap cached in memory and have a LFS with that looks like the following: how many disk I/Os do we need to perform to read the contents of the directory “/”?   block 0: Checkpoint region: imap -> 3block 1:  block 2:  block 3:

All the blocks in a given segment will be garbage or live in LFS.

Direct Memory Access (DMA) orchestrates the transfer of data between main memory and  devices without much CPU intervention.

LFS uses two checkpoint regions for redundancy in case of a crash during an update to one of the regions.

Gina, a 37-year-old client, discovered a “bump” in her vaginal introitus a few days ago. She says that it is small and painless, but she was concerned and decided to have it checked out. After conducting a vaginal examination, the nurse determines that the condition is a Bartholin duct cyst. At this point, the cyst is mild. What are the two best interventions that the NP should advise in response to this finding? (Select all that apply.)
