Question 57
Which of the following PBX feature supports shared extensions among several devices, ensuring that only one device at a time can use an extension?
Correct Answer: B
Section: Protection of Information Assets Explanation: Privacy release supports shared extensions among several devices, ensuring that only one device at a time can use an extension. For your exam you should know below mentioned PBX features and Risks: System Features Description Risk Automatic Call distribution Allows a PBX to be configured so that incoming calls are distributed to the next available agent or placed on-hold until one become available Tapping and control of traffic Call forwarding Allow specifying an alternate number to which calls will be forwarded based on certain condition User tracking Account codes Used to: Track calls made by certain people or for certain projects for appropriate billing Dial-In system access (user dials from outside and gain access to normal feature of the PBX) Changing the user class of service so a user can access a different set of features (i.e. the override feature) Fraud, user tracking, non authorized features Access Codes Key for access to specific feature from the part of users with simple instruments, i.e. traditional analog phones. Non-authorized features Silent Monitoring Silently monitors other calls Eavesdropping Conferencing Allows for conversation among several users Eavesdropping, by adding unwanted/unknown parties to a conference override(intrude) Provides for the possibility to break into a busy line to inform another user an important message Eavesdropping Auto-answer Allows an instrument to automatically go when called usually gives an auditor or visible warning which can easily turned off Gaining information not normally available, for various purpose Tenanting Limits system user access to only those users who belong to the same tenant group - useful when one company leases out part of its building to other companies and tenants share an attendant, trunk lines,etc Illegal usage, fraud, eavesdropping Voice mail Stores messages centrally and - by using a password - allows for retrieval from inside or outside lines. Disclosure or destruction of all messages of a user when that user's password in known or discovered by an intruder, disabling of the voice mail system and even the entire switch by lengthy messages or embedded codes, illegal access to external lines. Privacy release Supports shared extensions among several devices, ensuring that only one device at a time can use an extension. Privacy release disables the security by allowing devices to connect to an extension already in use. Eavesdropping No busy extension Allows calls to an in-use extension to be added to a conference when that extension is on conference and already off-hook Eavesdropping a conference in progress Diagnostics Allows for bypassing normal call restriction procedures. This kind of diagnostic is sometimes available from any connected device. It is a separate feature, in addition to the normal maintenance terminal or attendant diagnostics Fraud and illegal usage Camp-on or call waiting When activated, sends a visual audible warning to an off-hook instrument that is receiving another call. Another option of this feature is to conference with the camped-on or call waiting Making the called individual a party to a conference without knowing it. Dedicated connections Connections made through the PBX without using the normal dialing sequences. It can be used to create hot-lines between devices i.e. one rings when the other goes off-hook. It is also used for data connections between devices and the central processing facility Eavesdropping on a line The following were incorrect answers: Call forwarding - Allow specifying an alternate number to which calls will be forwarded based on certain condition Tenanting -Limits system user access to only those users who belong to the same tenant group - useful when one company leases out part of its building to other companies and tenants share an attendant, trunk lines,etc Voice Mail -Stores messages centrally and - by using a password - allows for retrieval from inside or outside lines.

Correct Answer: C
Question 60
Which of the following controls would provide the GREATEST assurance of database integrity?
Correct Answer: B
Explanation/Reference: Explanation: Performing table link/reference checks serves to detect table linking errors (such as completeness and accuracy of the contents of the database), and thus provides the greatest assurance of database integrity. Audit log procedures enable recording of all events that have been identified and help in tracing the events. However, they only point to the event and do not ensure completeness or accuracy of the database's contents. Querying/monitoring table access time checks helps designers improve database performance, but not integrity. Rollback and roll forward database features ensure recovery from an abnormal disruption. They assure the integrity of the transaction that was being processed at the time of disruption, but do not provide assurance on the integrity of the contents of the database.
