Which of the following is NOT a best practice for implementing disaster recovery plans? 

Keeping backup copies only at the primary site is not a best practice for disaster recovery. If a disaster strikes the primary site, such as a fire or natural disaster, both the original data and the backups could be lost. Best practices recommend keeping offsite backups in a separate location to ensure data can be restored even if the primary site is compromised. Cloud backups, remote data centers, or cold storage are common offsite options. Why other options are wrong: a) Regularly test the recovery plan : Regular testing ensures that the disaster recovery plan will work effectively when needed. c) Ensure offsite backups are maintained : Offsite backups are crucial for ensuring data availability in case of site-wide failure. d) Clearly define RTO and RPO : Defining RTO and RPO is critical for understanding recovery objectives and minimizing business impact. e) Use automated backup solutions : Automated backups reduce the chance of human error and ensure backups are conducted consistently.
