ISACA Certified Information Systems Auditor 認定 CISA 試験問題 (Q319-Q324):

質問 # 319
A financial services organization is developing and documenting business continuity measures. In which of the following cases would an IS auditor MOST likely raise an issue?

A. The recovery time objectives (RTOs) do not take IT disaster recovery constraints into account, such as personnel or system dependencies during the recovery phase.
B. The business continuity capabilities are planned around a carefully selected set of scenarios which describe events that might happen with a reasonable probability.
C. The organization uses good practice guidelines instead of industry standards and relies on external advisors to ensure the adequacy of the methodology.
D. The organization plans to rent a shared alternate site with emergency workplaces which has only enough room for half of the normal staff.

正解：B

解説：
Explanation/Reference:
Explanation:
It is a common mistake to use scenario planning for business continuity. The problem is that it is impossible to plan and document actions for every possible scenario. Planning for just selected scenarios denies the fact that even improbable events can cause an organization to break down. Best practice planning addresses the four possible areas of impact in a disaster: premises, people, systems, and suppliers and other dependencies. All scenarios can be reduced to these four categories and can be handled simultaneously. There are very few special scenarios which justify an additional separate analysis, it is a good idea to use best practices and external advice for such an important topic, especially since knowledge of the right level of preparedness and the judgment about adequacy of the measures taken is not available in every organization. The recovery time objectives (RTOs) are based on the essential business processes required to ensure the organization's survival, therefore it would be inappropriate for them to be based on IT capabilities. Best practice guidelines recommend having 20%-40% of normal capacity available at an emergency site; therefore, a value of 50% would not be a problem if there are no additional factors.

質問 # 320
Which of the following is MOST important to ensure successful implementation when an organization decides to purchase software from available products on the market?

A. Software escrow
B. Requirements definition
C. Post-implementation review
D. Support and maintenance contract

正解：B

解説：
Defining clear, comprehensive, and testable requirements is critical before selecting and implementing a software product. Without well-documented requirements, the risk of choosing a solution that does not align with business needs increases significantly. A support contract (C) is important for long-term use, and escrow (D) may protect against vendor insolvency, but neither ensures that the product fits the organization's objectives. A post-implementation review (B) only evaluates success after implementation, which may be too late to correct fundamental misalignment. ISACA's COBIT framework (BAI03 and BAI05) stresses the importance of requirements gathering as the foundation for effective solution acquisition and development.

質問 # 321
Which of the following should be of GREATEST concern to an IS auditor reviewing a system software development project based on agile practices?

A. Lack of user acceptance testing (UAT) sign off
B. Lack of weekly production releases
C. Lack of secure coding practices
D. Lack of change management documentation

正解：D

質問 # 322
Which of the following INCORRECTLY describes the layer function of the Application Layer within the TCP/IP model?

A. Provides reliable delivery
B. Perform data processing such as encryption, encoding, etc
C. Keeps separate the data of different applications
D. Provides user interface

正解：A

解説：
Explanation/Reference:
The word INCORRECTLY keyword is used in the question.
You need to find out the service or functionality which is not performed by application layer of a TCP/IP model.
The reliable or unreliable delivery of a message is the functionality of transport layer of a TCP/IP model.
For your exam you should know below information about TCP/IP model:
Network Models

Layer 4. Application Layer
Application layer is the top most layer of four layer TCP/IP model. Application layer is present on the top of the Transport layer. Application layer defines TCP/IP application protocols and how host programs interface with Transport layer services to use the network.
Application layer includes all the higher-level protocols like DNS (Domain Naming System), HTTP (Hypertext Transfer Protocol), Telnet, SSH, FTP (File Transfer Protocol), TFTP (Trivial File Transfer Protocol), SNMP (Simple Network Management Protocol), SMTP (Simple Mail Transfer Protocol) , DHCP (Dynamic Host Configuration Protocol), X Windows, RDP (Remote Desktop Protocol) etc.
Layer 3. Transport Layer
Transport Layer is the third layer of the four layer TCP/IP model. The position of the Transport layer is between Application layer and Internet layer. The purpose of Transport layer is to permit devices on the source and destination hosts to carry on a conversation. Transport layer defines the level of service and status of the connection used when transporting data.
The main protocols included at Transport layer are TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
Layer 2. Internet Layer
Internet Layer is the second layer of the four layer TCP/IP model. The position of Internet layer is between Network Access Layer and Transport layer. Internet layer pack data into data packets known as IP datagram's, which contain source and destination address (logical address or IP address) information that is used to forward the datagram's between hosts and across networks. The Internet layer is also responsible for routing of IP datagram's.
Packet switching network depends upon a connectionless internetwork layer. This layer is known as Internet layer. Its job is to allow hosts to insert packets into any network and have them to deliver independently to the destination. At the destination side data packets may appear in a different order than they were sent. It is the job of the higher layers to rearrange them in order to deliver them to proper network applications operating at the Application layer.
The main protocols included at Internet layer are IP (Internet Protocol), ICMP (Internet Control Message Protocol), ARP (Address Resolution Protocol), RARP (Reverse Address Resolution Protocol) and IGMP (Internet Group Management Protocol).
Layer 1. Network Access Layer
Network Access Layer is the first layer of the four layer TCP/IP model. Network Access Layer defines details of how data is physically sent through the network, including how bits are electrically or optically signaled by hardware devices that interface directly with a network medium, such as coaxial cable, optical fiber, or twisted pair copper wire.
The protocols included in Network Access Layer are Ethernet, Token Ring, FDDI, X.25, Frame Relay etc.
The most popular LAN architecture among those listed above is Ethernet. Ethernet uses an Access Method called CSMA/CD (Carrier Sense Multiple Access/Collision Detection) to access the media, when Ethernet operates in a shared media. An Access Method determines how a host will place data on the medium.
IN CSMA/CD Access Method, every host has equal access to the medium and can place data on the wire when the wire is free from network traffic. When a host wants to place data on the wire, it will check the wire to find whether another host is already using the medium. If there is traffic already in the medium, the host will wait and if there is no traffic, it will place the data in the medium. But, if two systems place data on the medium at the same instance, they will collide with each other, destroying the data. If the data is destroyed during transmission, the data will need to be retransmitted. After collision, each host will wait for a small interval of time and again the data will be retransmitted.
Protocol Data Unit (PDU) :
Protocol Data Unit - PDU

The following answers are incorrect:
The other options correctly describe functionalities of application layer in TCP/IP model.
The following reference(s) were/was used to create this question:
CISA review manual 2014 page number 272

質問 # 323

正解：B
