You have critical backups that are made at night and taken to an offsite location. which of the following would allow for a minimal amount of downtime in the case of a disaster?
a. make the offsite location into a cold site.
b. have a backup server at the offsite location.
c. make the offsite location into a hot site.
d. make the offsite location into a warm site.

Make the offsite location into a hot site will be followed for a minimal amount of downtime in case of disaster.

Option C

An external hot site disaster recovery is a viable option because in the case of disaster it remains fully functional. It is preferable for companies that deal with critical data which cannot tolerate any system malfunction. This type of recovery is the most expensive compared to cold and warm site.

The decision to keep it external that is, offsite could be due to lack of resources and staffing. In this case, management is the provider’s responsibility. Depending on the organisation, the external site can be of service to one organisation or space rented by multiple organisations.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
