A security team recommends a disaster recovery plan with the following requirements: -> Recent backups should be readily available.
-> Only long-term backups should be stored off premises.
-> There should be minimum expenditure on hardware.
Which of the following satisfies all of these requirements?

A. B. C. D.A.
The security team's disaster recovery plan has three main requirements:
Option A suggests storing 30 days of backups on premises and then aging the backups to the public cloud. This option satisfies the first requirement by ensuring recent backups are readily available. It also satisfies the second requirement by storing long-term backups off-premises in the public cloud. However, it may not satisfy the third requirement of minimum hardware expenditure, as it requires on-premises storage for 30 days of backups.
Option B suggests storing backups on premises and bursting to the public cloud if needed. This option satisfies the first requirement of readily available backups, but it does not satisfy the second requirement of storing long-term backups off-premises. Additionally, it may not satisfy the third requirement of minimum hardware expenditure, as it still requires on-premises storage for backups.
Option C suggests storing backups both on premises and in a public cloud infrastructure. This option satisfies the first requirement of readily available backups and the second requirement of storing long-term backups off-premises. It also satisfies the third requirement of minimum hardware expenditure, as it does not require excessive on-premises storage.
Option D suggests storing all backups in a public cloud with no on-premises backup storage. This option satisfies the second requirement of storing long-term backups off-premises, but it does not satisfy the first requirement of readily available backups. It also may not satisfy the third requirement of minimum hardware expenditure, as it requires a reliable and consistent internet connection for data restoration.
Therefore, the option that satisfies all three of the security team's requirements is option C, storing backups both on premises and in a public cloud infrastructure.
