  Correct Answer: B

• Question 1394:

  A. Elasticity

  B. Scalability

  C. High availability

  D. Redundancy

  Correct Answer: A

  Elasticity is defined as "the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible".

  B. Homogeneity

  C. Resiliency

  D. Configurability

  Correct Answer: C

  A. tracert

  B. netstat

  C. ping

  D. nslookup

  Correct Answer: B

• Question 1399:

  DRAG DROP

  A security administrator is given the security and availability profiles for servers that are being deployed.

  Match each RAID type with the correct configuration and MINIMUM number of drives.

  Review the server profiles and match them with the appropriate RAID type based on integrity, availability, I/O, storage requirements. Instructions:

  1.

  All drive definitions can be dragged as many times as necessary

  2.

  Not all placeholders may be filled in the RAID configuration boxes

  3.

  If parity is required, please select the appropriate number of parity checkboxes

  4.

  Server profiles may be dragged only once

  Instructions: If at any time you would like to bring back the initial state of the simulation, please select the Reset button. When you have completed the simulation, please select the Done button to submit. Once the simulation is submitted, please select the Next button to continue.

  Select and Place:

  

  Correct Answer:

  

  RAID-0 is known as striping. It is not a fault tolerant solution but does improve disk performance for read/write operations. Striping requires a minimum of two disks and does not use parity. RAID-0 can be used where performance is required

  over fault tolerance, such as a media streaming server.

  RAID-1 is known as mirroring because the same data is written to two disks so that the two disks have identical data. This is a fault tolerant solution that halves the storage space. A minimum of two disks are used in mirroring and does not

  use parity. RAID-1 can be used where fault tolerance is required over performance, such as on an authentication server.

  RAID-5 is a fault tolerant solution that uses parity and striping. A minimum of three disks are required for RAID-5 with one disk's worth of space being used for parity information.

  However, the parity information is distributed across all the disks. RAID-5 can recover from a sing disk failure.

  RAID-6 is a fault tolerant solution that uses dual parity and striping. A minimum of four disks are required for RAID-6. Dual parity allows RAID-6 to recover from the simultaneous failure of up to two disks. Critical data should be stored on a

  RAID-6 system.

  Hot Area:

  

  Correct Answer:

  

  

  1: Spear phishing is an e-mail spoofing fraud attempt that targets a specific organization,seeking unauthorized access to confidential data. As with the e-mail messages used in regular phishing expeditions, spear phishing messages appear to

  come from a trusted source. Phishing messages usually appear to come from a large and well-known company or Web site with a broad membership base, such as eBay or PayPal. In the case of spear phishing, however, the apparent source

  of the e-mail is likely to be an individual within the recipient's own company and generally someone in a position of authority.

  2: The Hoax in this question is designed to make people believe that the fake AV (antivirus) software is genuine.

  3: Vishing is the act of using the telephone in an attempt to scam the user into surrendering private information that will be used for identity theft. The scammer usually pretends to be a legitimate business, and fools the victim into thinking he

  or she will profit.

  4: Phishing is the act of sending an email to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft.

  Phishing email will direct the user to visit a website where they are asked to update personal information, such as a password, credit card, social security, or bank account numbers, that the legitimate organization already has. The website,

  however, is bogus and set up only to steal the information the user enters on the page.

  5: Similar in nature to e-mail phishing, pharming seeks to obtain personal or private (usually financial related) information through domain spoofing. Rather than being spammed with malicious and mischievous e-mail requests for you to visit

  spoof Web sites which appear legitimate, pharming 'poisons' a DNS server by infusing false information into the DNS server, resulting in a user's request being redirected elsewhere. Your browser, however will show you are at the correct

  Web site, which makes pharming a bit more serious and more difficult to detect. Phishing attempts to scam people one at a time with an e-mail while pharming allows the scammers to target large groups of people at one time through domain

  spoofing.
