Which of the following correct modes, can be used to apply loopback policy?
select one or more:
a. merge mode
b. replace mode
c. remote mode
d. local mode

(A) Merge mode and (B) Remote mode

Explanation:

 The merge and remote mode is basically used in the loop-back policy. The loop back policy is used in the computer configuration as the group policy of the management editor.

The loop-back policy is basically allowed the administrator for access the setting of the group policy.When the merge mode are enable in the loop back policy then, the computer configuration are basically based on the particular computer configuration that are located in the computer active directory.  

Remote mode is also used to apply in the loop back policy and when this mode enabled then, it change the user configuration. In the active directory of the replace mode the user settings is basically based on the configuration of the user setting.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
