1. How can you recover from an unexpected data loss event? Check all that apply.
- Write a post-mortem report.
- Recover data from damaged
devices.
- Restore data from backups.
- Design a disaster recovery plan.
2. Where is it best to
store backups, physically?
- On-site
- Off-site
- In a safe
- Across multiple locations
Explanation: It is
crucial to strike a balance between redundancy, security, and accessibility in
accordance with the specific requirements of your organization and the
importance of the backed-up data. Consistent surveillance and testing of backup
and recovery procedures are additionally critical in order to ascertain the
efficacy of the selected storage solution.
3. Which of these should
be included in your backups? Check all that apply.
- Firewall configurations
- A downloads folder
- Family vacation photos
- Sales databases
4. What’s magnetic tape
backup media best suited for?
- Long-term archival data
- Low-latency cached data
- Cheap backup systems
- Quick and efficient backups
5. Why is it important
to test backups and restoration procedures? Check all that apply.
- To reduce the size of backup data
- To speed up the
backup-and-restore process
- To ensure backups work and data
can be restored from them
- To ensure that relevant data is
included in the backups
6. Which of the
following backup types are most space-efficient?
- Full backups
- Differential backups
- Incremental backups
Explanation: Differential
backups offer a compromise between space efficiency and restore procedure
simplicity. While they capture more data than incremental backups, they are
more space-efficient than complete backups.The selection between differential
and incremental backups is contingent upon various considerations, including
backup frequency, storage capacity, and the preferred trade-off between space
efficiency and restore simplicity.
7. True or false: You
can use a RAID array and use rsync to copy critical data to it for backups.
- True
- False
Explanation: In
conclusion, it is advisable to integrate a RAID array with rsync for routine
backups in order to bolster data redundancy and mitigate the risk of hardware
malfunctions. Nevertheless, it is imperative to supplement this with a
comprehensive backup strategy that encompasses a wide range of potential data
loss scenarios.
8. What
elements should a disaster recovery plan cover? Check all that apply.
- Detection measures
- Preventative measures
- Recovery measures
- Drastic measures
9. Why are detection
measures included in a disaster recovery plan?
- They aren’t
- Because it’s important to know
when a disaster occurs
- Because they prevent data loss
- Because they make recovering from
data loss easier
Explanation: In
conclusion, it is critical for organizations to incorporate detection measures
into their disaster recovery plans in order to proactively identify potential
threats and incidents. This allows them to safeguard their assets, operations,
and data through prompt and effective responses.
10. What are good
preventative measures to incorporate in your organization? Check all that
apply.
- Monitoring and alerting systems
- Redundant systems
- Regular backups
- Accessible and up-to-date
documentation
Explanation: Organizations
can mitigate the likelihood of cybersecurity incidents and establish a robust
security posture by implementing the aforementioned preventative measures. It
is critical to customize these metrics in accordance with the particular
requirements and attributes of the institution.
11. What are good
detection measures to incorporate in your organization? Check all that apply.
- Environmental monitoring
- Backing up firewall rules
- Redundant power supplies
- System performance
monitoring
Explanation: Through
the integration of these detection measures, organizations can substantially
bolster their capacity to recognize and address security incidents, thereby
augmenting their cybersecurity resilience as a whole. It is worth noting that a
multifaceted and integrated approach to detection is frequently the most
effective.
12. What are good
recovery measures to incorporate in your organization? Check all that apply.
- Restoring server configs from
backup
- Following detailed recovery plan
documentation
- Monitoring for internet line
outages
- Maintaining redundant servers
