ISACA copyright Auditor Sample Questions (Q593-Q598):

NEW QUESTION # 593
An IS auditor finds that a system under development has 12 linked modules and each item of data can carry up to 10 definable attribute fields. The system handles several million transactions a year. Which of these techniques could an IS auditor use to estimate the size of the development effort?

  • A. White box testing
  • B. Program evaluation review technique (PERT)
  • C. Function point analysis
  • D. Counting source lines of code (SLOC)

Answer: C

Explanation:
Explanation/Reference:
Explanation:
Function point analysis is an indirect method of measuring the size of an application by considering the number and complexity of its inputs, outputs and files. It is useful for evaluating complex applications.
PERT is a project management technique that helps with both planning and control. SLOC gives a direct measure of program size, but does not allow for the complexity that may be caused by having multiple, linked modules and a variety of inputs and outputs. White box testing involves a detailed review of the behavior of program code, and is a quality assurance technique suited to simpler applications during the design and build stage of development.


NEW QUESTION # 594
During a follow-up audit, an IS auditor learns that some key management personnel have been replaced since the original audit, and current management has decided not to implement some previously accepted recommendations. What is the auditor's BEST course of action?

  • A. Close the audit finding.
  • B. Notify the audit manager.
  • C. Notify the chair of the audit committee.
  • D. Retest the control.

Answer: B


NEW QUESTION # 595
An organization with high availability resource requirements is selecting a provider for cloud computing.
Which of the following would cause the GREATEST concern to an IS auditor? The provider:

  • A. is not internationally certified for high availability.
  • B. hosts systems for the organization's competitor.
  • C. deploys patches automatically without testing.
  • D. does not store backup media offsite.

Answer: C


NEW QUESTION # 596
Which of the following device in Frame Relay WAN technique is generally customer owned device that provides a connectivity between company's own network and the frame relays network?

  • A. DLE
  • B. DME
  • C. DCE
  • D. DTE

Answer: D

Explanation:
Explanation/Reference:
Data Terminal Equipment (DTE) - Usually a customer owned device that provides connectivity between company's own network and the frame relay's network.
For your exam you should know below information about WAN Technologies:
Point-to-point protocol
PPP (Point-to-Point Protocol) is a protocol for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server. For example, your Internet server provider may provide you with a PPP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you.
PPP uses the Internet protocol (IP) (and is designed to handle other protocol as well). It is sometimes considered a member of the TCP/IP suite of protocols. Relative to the Open Systems Interconnection (OSI) reference model, PPP provides layer 2 (data-link layer) service. Essentially, it packages your computer's TCP/IP packets and forwards them to the server where they can actually be put on the Internet.
PPP is a full-duplex protocol that can be used on various physical media, including twisted pair or fiber optic lines or satellite transmission. It uses a variation of High Speed Data Link Control (HDLC) for packet encapsulation.
PPP is usually preferred over the earlier de facto standard Serial Line Internet Protocol (SLIP) because it can handle synchronous as well as asynchronous communication. PPP can share a line with other users and it has error detection that SLIP lacks. Where a choice is possible, PPP is preferred.

X.25
X.25 is an ITU-T standard protocol suite for packet switched wide area network (WAN) communication.
X.25 is a packet switching technology which uses copyright switch to provide connectivity for many different networks.
Subscribers are charged based on amount of bandwidth they use. Data are divided into 128 bytes and encapsulated in High Level Data Link Control (HDLC).
X.25 works at network and data link layer of an OSI model.

1. Data Terminal Equipment (DTE) - Usually a customer owned device that provides connectivity between company's own network and the frame relay's network.
2. Data Circuit Terminal Equipment (DCE) - Service provider device that does the actual data transmission and switching in the frame relay cloud.
The Frame relay cloud is the collection of DCE that provides that provides switching and data communication functionality. Frame relay is any to any service.

Integrated Service Digital Network (ISDN)
Enables data, voice and other types of traffic to travel over a medium in a digital manner previously used only for analog voice transmission.
Runs on top of the Plain Old Telephone System (POTS). The same copper telephone wire is used.
Provide digital point-to-point circuit switching medium.

Asynchronous Transfer Mode (ATM)
Uses Cell switching method
High speed network technology used for LAN, MAN and WAN
Like frame relay it is connection oriented technology which creates and uses fixed channel Data are segmented into fixed size cell of 53 bytes Some companies have replaces FDDI back-end with ATM Asynchronous Transfer Mode

Multiprotocol Label Switching (MPLS)
Multiprotocol Label Switching (MPLS) is a standard-approved technology for speeding up network traffic flow and making things easier to manage.MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to.
MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and frame relay network protocols.
In reference to the Open Systems Interconnection, or OSI model, MPLS allows most packets to be forwarded at Layer 2 (switching) level rather than at the Layer 3 (routing) level.
In addition to moving traffic faster overall, MPLS makes it easy to manage a network for quality of service (QoS). For these reasons, the technique is expected to be readily adopted as networks begin to carry more and different mixtures of traffic.

Image from: http://www.carrierbid.com/wp-content/uploads/2011/01/mpls1.gif The following answers are incorrect:
DCE - Data Circuit Terminal Equipment (DCE) is a service provider device that does the actual data transmission and switching in the frame relay cloud.
DME - Not a valid frame relay technique
DLE - Not a valid frame relay technique

  • C. Roles and responsibilities are documented.
  • D. Tabletop disaster recovery tests are conducted
