Chapter 8: Business Continuity (BC) Flashcards
Understand Business Continuity (BC)
{Blank} efforts are activities designed to keep a business running in face of adversity.
Business continuity
The {blank} is an impact assessment that begins by identifying the organization’s mission-essential functions and the tracing those backward to identify the critical IT systems that support those processes.
Business Impact Analysis (BIA)
{Blank} identify places where the failure of one component could cause an entire system or service to become unavailable.
Single point of failure analyses
{Blank} uses multiple systems to protect against failures.
High Availability (HA)
{Blank} helps to protect a single system from failing in the first place by making it resilient in the face of technical failures.
Fault Tolerance (FT)
What are the three components most likely to fail on a computer system?
- Power supply
- Storage
- Network connection
Business continuity planning (BCP) is one of the core responsibilities of the information security profession.
The focus of business continuity id keeping operations running, so BCP is sometimes referred to as {blank}.
Continuity of Operations Planning (COOP)
{Blank} uses mulitple systems to spread out the burden of providing service across thoses systems, providing a scalable computing environment.
Load Balancing
{Blank} provides battery power to systems in the event of a brief disruption.
Uninterruptible Power Supplies (UPS)
Managed {blank} work to manage the power within a rack, ensuring that the power delivered to devices is clean and managed.
Power Distribution Units (PDUs)
What are the two major redundant arrays of inexpensive disks (RAID) technologies?
- Disk mirroring
- Disk striping parity
The most basic for of RAID, known as {blank}, is disk mirroring. In this approach, the sever contains two disks. Each disk has identical contents, and when the system writes any data to one disk, it automatically makes the same changes to the other disk, keeping it as a synchronized copy, or mirror, of primary disk.
RAID Level 1
Disk striping with parity, known as {blank}. In this approach, the system contains three or more disks and writes data across all of those disks but includes additional elements known as parity blocks across all disks.
RAID Level 5
Renee would like to add fault tolerance to the storage capacity of a new server that she is building. She would like to use RAID 5 to protct this server. What is the smallest number of physical disks that she can use?
A. 1
B. 2
C. 3
D. 5
3
Kevin is designing a new web server environment for his organization. He believes that the service will need three servers to support normal traffic levels and decides to use three servers to meet that need. As requests come in, they will be sent to the server that has the most available capacity. Which term best describes what Kevin is doing?
A. Fault tolerance
B. High availability
C. Dual power supplies
D. Load balancing
