1
Q
RAID-1
A
RAID-1
- Data mirrored on two disks
- No striping or parity
- 2 drives - can survive loss of one drive
- More drives - works as long as one drive survives
2
Q
RAID-5
- Number of drives
- striping/mirroring/parity?
- How many can be lost
- How much space available?
A
RAID-5
- Three or more disks striped like RAID-0
- Parity info striped across all drives
- Can survive loss of one drive
- Equivalent of one drive for parity, so space available equal to size remaining drives
3
Q
RAID-6
- Number of disks
- mirroring/stiping/parity
- number of disk you can lose
- How much space available?
A
RAID-6
- Extension of RAID-5
- Minimum of four disks
- Striping
- Double parity block distributed to all disks
- Can survive loss of two disks
- Equivalent of two drives for parity, so space available is equal to size of remaining drives
4
Q
RAID-10
-striping/mirroring/parity
A
RAID-10
- Combines mirroring and striping
- no parity
- Requires at leas four disks
- Add two disks at a time
- If four 500 GB disks -> 1 TB of storage (cuts space in half)
- Can survive loss of two drives (depends on which two drives)
5
Q
Active-Active Load Balancer
A
Active-Active Load Balancer
-All servers process requests
6
Q
Active-Passive Load Balancer
A
Active-Passive Load Balancer
-At least one server monitoring and ready to take over
7
Q
Software-Based Load Balancer
A
Software-Based Load Balancer
-Virtual IP address
8
Q
Affinity Scheduling
A
Affinity Scheduling
- Load balancers
- Sends client requests to same server based on client’s IP address
9
Q
Full Backup
A
Full Backup
- Quickest recovery time
- Archive attribute: Cleared
10
Q
Differential Backup
A
Differential Backup
- Each day back up data that changed since last FULL backup (D is next to F in alphabet)
- As time passes, differential backups grow
- Differential backup reduces time to restore
- To recover, need two backups - last full and last differential
- Archive attribute: NOT Cleared
11
Q
Incremental Backup
A
Incremental Backup
- Full
- Each day back up data that changed since last INCREMENTAL (or full) backup
- As time passes, incremental backups stay about the same size
- Incremental backup reduces time to backup
- To recover, start with last full, then each incremental
- Archive attribute: Cleared
12
Q
BIA
A
BIA Business Impact Assessment -Part of BCP (Business Continuity Plan) -Identifies mission-essential functions and critical systems -Max downtime -Scenarios -Potential losses
13
Q
Privacy Threshold Assessment
A
Privacy Threshold Assessment
- Identifies PII in system
- Simple questionnaire
- If PII, conduct Privacy Impact Assessment
14
Q
Privacy Impact Assessment
A
Privacy Impact Assessment
- Identify and reduce risks related to loss of PII by reviewing how it’s handled
- Ensure complying with laws, regs
15
Q
RTO
A
RTO
Recovery Time Objective
-Max time to restore system after outage
-Derived from max allowable outage time in BIA
