WGU C795 UPDATED EXAM SCRIPT ACTUAL QUESTIONS
AND SOLUTIONS RATED A+
✔✔T&A training and awareness - ✔✔o Orientation training for all new employees
o Initial training for employees taking on a new disaster recovery role for the first time
o Detailed refresher training for disaster recovery team members
Brief awareness refreshers for all other employees
✔✔Disk to Disk - ✔✔disk storage has become increasingly inexpensive. With drive
capacities now measured in terabytes, tape and optical media can't cope with data
volume requirements anymore. Many enterprises now use disk-to-disk (D2D) backup
solutions for some portion of their disaster recovery strategy.
✔✔Software escrow arrangement - ✔✔is a unique tool used to protect a company
against the failure of a software developer to provide adequate support for its products
or against the possibility that the developer will go out of business and no technical
support will be available for the product.
✔✔Remote Mirroring - ✔✔Maintaining a live database server at the backup site. It is the
most advanced database backup solution.
✔✔Remote Journaling - ✔✔A database backup type which records at the transaction
level
✔✔Electronic vaulting scenario - ✔✔database backups are moved to a remote site
using bulk transfers.
✔✔Cold Sites (Disaster recovery): - ✔✔A "recovery" cold site is essentially data center
space, with power, and network connectivity that is available when needed. In the event
of a disaster, teams can move and install a business's hardware at the cold site in order
to get the systems back up and running.
✔✔hot site - ✔✔A separate and fully equipped facility where the company can move
immediately after a disaster and resume business
✔✔Warm Sites (Disaster recovery): - ✔✔A "preventative" warm site allows a business
to pre-install hardware and pre-configure their bandwidth needs. In the event of a
disaster, the business can then load their software and restore their business systems.
✔✔Mobile Sites - ✔✔self-contained trailers or other easily relocated units. These sites
include all the environmental control systems necessary to maintain a safe computing
environment.
✔✔Service Bureau - ✔✔Recovery alternative which outsources a business function at a
cost
, leases computer time. Service bureaus own large server farms and often fields of
workstations.
✔✔Function Recovery - ✔✔able to automatically recover specific functions
-ensures system is able to successfully complete the recovery for the functions
✔✔Automated Recovery - ✔✔system is able to perform trusted recovery activities to
restore itself against at least one type of failure
✔✔• Automated Recovery without Undue Loss - ✔✔This is similar to automated
recovery in that a system can restore itself against at least one type of failure.
✔✔Manual Recovery - ✔✔If a system fails, it does not fail in a secure state. Instead, an
administrator is required to manually perform the actions necessary to implement a
secured or trusted recovery after a failure or system crash.
✔✔Fail Secure System - ✔✔will default to a secure state in the event of a failure,
blocking all access. A fail-open system will fail in an open state, granting all access.
✔✔Trusted recovery - ✔✔provides assurances that after a failure or crash, the system
is just as secure as it was before the failure or crash occurred.
✔✔Fault tolerance - ✔✔can be added for power sources with an uninterruptible power
supply (UPS), a generator, or both.
✔✔failover cluster - ✔✔A set of independent computers that work together to increase
the availability of services and applications.
✔✔RAID-0 - ✔✔A RAID array in which every time data is written to disk, a portion
(block) is written to each disk in turn, creating a "stripe" of data across the member
disks. RAID 0 uses the total disk space in the array for storage, without protecting the
data from drive failure. (2)
✔✔RAID 1 - ✔✔Mirroring
✔✔RAID 5 - ✔✔A technique that stripes data across three or more drives and uses
parity checking, so that if one drive fails, the other drives can re-create the data stored
on the failed drive. RAID 5 drives increase performance and provide fault tolerance.
Windows calls these drives RAID-5 volumes.
✔✔RAID 10 - ✔✔a combination of RaID 1 and RaID 0 that requires at least four disks to
work as an array of drives and provides the best redundancy and performance.
