Consider an RAID-5 storage with 5 disk drives. A block read takes 10 time units, a block write takes 5 time units, and computing an XOR result of two blocks takes 1 time unit. Assume only one XOR operation can be performed each time (i. e., XOR operations cannot be done in parallel). A stripe (a row) has four data blocks (A, B, C, and D) and a parity block P, which are stored in the five disks, one in each disk respectively. If we need to write one data block A, give two methods to update this stripe in the RAID-5 storage. Explain each method step by step, and calculate the corresponding time cost that is needed for each method to complete the operations.

You are working as a security analyst in a company xyz that owns the whole subnet range of 23.0.0.0/8 and 192.168.0.0/8. while monitoring the data, you find a high number of outbound connections. you see that ip's owned by xyz (internal) and private ip's are communicating to a single public ip. therefore, the internal ip's are sending data to the public ip. after further analysis, you find out that this public ip is a blacklisted ip, and the internal communicating devices are compromised. what kind of attack does the above scenario depict?
