A company is hosting an SQL, cloud, and web server at its own
premises. Which of these backup locations would you recommend as the
safest option for backup storage and later retrieval of the web server's
data?
A. A backup server placed in the server room, along with the web server
B. A magnetic tape stored on the premises but in a different building
C. An encrypted copy of the data backed up on the company cloud
server
D. Backup of the data stored on Amazon AWS Ans✓✓✓D. A backup
of the data on a third-party cloud is the safest option, as that ensures the
data survives any physical disaster that the main server room faces.
A company wants to select a dedicated alternative location for
continuing its operations in the event of an incident, while minimizing
operational downtime. Which of the following would be most
appropriate for that purpose?
A. Hot site
B. Warm site
C. Cold site
D. Mobile site Ans✓✓✓A. A "hot site" is the best choice for this
purpose, as it offers a dedicated alternative location for continuing
operations in the event of any incident rendering the primary location
unusable. Such a site has everything in place (i.e., HVAC, network
infrastructure, hardware) so the organization can continue operating.
,A company wants to select a dedicated alternative location for
continuing its operations in the event of an incident. They have some
budget limitations and can cope with operating from an alternative
location within 24 to 48 hours of any major incident that might
compromise the primary location. Which of the following would be
most appropriate for that purpose?
A. Hot site
B. Warm site
C. Cold site
D. Mobile site Ans✓✓✓B. A "warm site" would be most suitable in
this case. It offers some of the capabilities of a "hot site" but not all of
them (i.e., commonly the data from the primary location is not up to date
and synchronization needs to take place before commencing operations).
However, the cost of maintaining a "warm site" is significantly lower
than that of a "hot site." In addition, such a site would be usually
available within a matter of hours, commonly up to 24, which aligns
with the organization's requirements.
A company's backup policy states that a full backup is performed every
Friday at 9:00 P.M. Differential backups are performed daily at 8:00
P.M. If a server goes down at 11:00 P.M. on Tuesday evening, how
many backups in total will be required to restore the server?
A. 1
B. 2
C. 3
D. 4 Ans✓✓✓B. As per the company policy, a full backup will first be
taken on Friday at 9:00 P.M. Following that, differential backups will be
taken on Saturday, Sunday, Monday, and Tuesday at 8:00 P.M. Finally,
, after those are taken, the server goes down. As you may remember,
when a differential backup is taken, all changes from the previous full
backup are recorded. Since the server went down at 11:00 P.M. on
Tuesday and a differential backup was taken three hours prior to that, a
restoration process will only require that backup in addition to the full
backup taken last Friday. Hence, a total of two backups will be required.
A company's backup policy states that a full backup is performed every
Monday at 9:00 P.M. Incremental backups are performed daily at 12:00
P.M. If a server goes down at 8:30 P.M. on Thursday evening, how
many backups in total will be required to restore the server?
A. 1
B. 2
C. 3
D. 4 Ans✓✓✓D. As per the organizational backup policy, a full backup
will take place on Monday at 9:00 P.M. Following that, an incremental
backup will take place on Tuesday at 12:00 P.M., as well as Wednesday
and Thursday at the same time. After the last incremental backup
(Thursday at 12:00 P.M.), the server goes down (8:30 P.M. on
Thursday). That means all previously mentioned backups will need to be
used to restore the server to its most current state, meaning all four (one
full and three incremental ones).
A company's backup policy states that a full backup is performed every
Tuesday at 8:00 A.M. Incremental backups are performed daily at 6:00
P.M. If a server goes down at 4:30 P.M. on the following Sunday
evening, how many full backups will be required to restore the server?
A. 1
