What is the consistency issue raised by state transfer?
What will be an ideal response?
When a process joins a group it acquires state S from one or more members of the group. It may then start receiving messages destined for the group, which it processes. The consistency problem consists of ensuring that no update message that is already reflected in the value S will be applied to it again; and, conversely, that any update message that is not reflected in S will be subsequently received and processed.

1. The sequential search algorithm is the simplest of all array searching algorithms. 2. An array and the variable that references it hold the same value. 3. If you want to make a separate copy of an array, you must create the second array in memory and then copy the individual elements of the first array to the second. This is known as a deep copy. 4. You can use the == operator to compare two array reference variables and determine whether the array contents are equal. 5.
