• Question 241:

  When reviewing the disaster recovery plan for two data centers, you find that: The copy of data at remote Site B will lag behind the production data at Site A by 5 minutes It will take 2 hours after an outage at Site A to shift production to Site B. Three more hours will be needed to power up the servers, bring up the network, and redirect users to Site

  A. What is the recovery point objective (RPO) of this plan?
  B. 5 minutes
  C. 2 hours
  D. 5 hours
  E. 5 hours 5 minutes
  A. What is the recovery point objective (RPO) of this plan?

  BC Terminologies

  

  Recovery-Point Objective (RPO): This is the point-in-time to which systems and data must be recovered after an outage. It defines the amount of data loss that a business can endure. Based on the RPO, organizations plan for the frequency

  with which a backup or replica must be made. An organization can plan for an appropriate BC technology solution on the basis of the RPO it sets.

  RPO of 24 hours: Backups are created at an offsite tape library every midnight. The corresponding recovery strategy is to restore data from the set of last backup tapes.

  RPO of 1 hour: Shipping database logs to the remote site every hour. The corresponding recovery strategy is to recover the database to the point of the last log shipment.

  RPO in the order of minutes: Mirroring data asynchronously to a remote site.

  RPO of zero: Mirroring data synchronously to a remote site. Recovery-Time Objective (RTO): The time within which syste Recovery-Time Objective (RTO): The time within which systems and applications must be recovered after an outage. It

  defines the amount of downtime that a business can endure and survive.

  A. Single hierarchical solution for security
  B. Multiple integrated layers of security
  C. Multiple isolated solutions for security
  D. Multiple isolated layers of security
  B. Multiple integrated layers of security

  SAN Security Architecture: Defense in Depth Storage networking environments are a potential target for unauthorized access, theft, and misuse because of the vastness and complexity of these environments. Therefore, security strategies are based on the defense in depth concept, which recommends multiple integrated layers of security. This ensures that the failure of one security control will not compromise the assets under protection. EMC E10-001 Student Resource Guide. Module 14: Securing the Storage Infrastructure
