Q25. Explain About Global Catalog?

Global Catalog

Global catalog (GC) is a position handled by means of area controllers in an Active listing version. 

The international catalog shops a complete copy of all objects in the listing for its host domain and a partial reproduction of all items for all different domains inside the wooded area. 

‘Partial replica’ refers to the set of attributes which can be most used for looking every item in every domain.

All area controllers may be promoted as a GC. 

GC enables in quicker seek of AD objects.  

The replicas which are replicated to the global catalog also consist of the get right of entry to permissions for each object and characteristic. 

If you're trying to find an item which you do not have permission to get entry to, you do no longer see the item in the list of seek consequences. Users can find only objects to which they're allowed get entry to.

Global catalog server clients depend upon DNS to offer the IP cope with of world catalog servers. DNS is needed to advertise worldwide catalog servers for area controller location.

By default, first DC of in a wooded area could be a global catalog server

Q50. What Is The Difference Between Raid 1 And Raid 5 ?

 RAID 1 - Mirroring - This RAID configuration gives you maximum redundancy because the equal information is written into  disks at a time. But this solution could be pricey as you constantly need to have disks double of what you genuinely require. Minimum 2 disks required.

RAID five - This RAID is the most popular RAID configuration. This works at the parity principle. Minimum three disks required. Even if one disk fail, the statistics of the failed disk can be calculated from the parity stored in the other 2 disks.
