NEW QUESTION # 540
Which of the following is the GREATEST risk when storage growth in a critical file server is not managed properly?
- A. Storage operational cost would significantly increase
- B. Backup time would steadily increase
- C. Backup operational cost would significantly increase
- D. Server recovery work may not meet the recovery time objective (RTO)
Answer: D
Explanation:
Explanation/Reference:
Explanation:
In case of a crash, recovering a server with an extensive amount of data could require a significant amount of time. If the recovery cannot meet the recovery time objective (RTO), there will be a discrepancy in IT strategies. It's important to ensure that server restoration can meet the RTO. Incremental backup would only take the backup of the daily differential, thus a steady increase in backup time is not always true. The backup and storage costs issues are not as significant as not meeting the RTO.
NEW QUESTION # 541

NEW QUESTION # 542
In wireless communication, which of the following controls allows the device receiving the communications to verify that the received communications have not been altered in transit?
- A. Wireless intrusion detection (IDS) and prevention systems (IPS)
- B. The use of cryptographic hashes
- C. Device authentication and data origin authentication
- D. Packet headers and trailers
Answer: B
Explanation:
Calculating cryptographic hashes for wireless communications allows the device receiving the communications to verify that the received communications have not been altered in transit. This prevents masquerading and message modification attacks. Device authentication and data origin authentication is not the correct answer since authenticating wireless endpoints to each other prevents man-in-the-middle attacks and masquerading. Wireless iDS / lPSs is not the correct answer since wireless IDS/ lPSshave the ability to detect misconfigured devices and rogue devices, and detect and possibly stop certain types of attacks. Packet headers and trailers alone do not ensure that the content has not been altered.
NEW QUESTION # 543

NEW QUESTION # 544
The network of an organization has been the victim of several intruders' attacks. Which of the following measures would allow for the early detection of such incidents?
- A. Honeypots
- B. Antivirus software
- C. Hardening the servers
- D. Screening routers
Answer: A
Explanation:
Section: Protection of Information Assets
Explanation:
Honeypots can collect data on precursors of attacks. Since they serve no business function, honeypots are hosts that have no authorized users other than the honeypot administrators. All activity directed at them is considered suspicious. Attackers will scan and attack honeypots, giving administrators data on new trends and attack tools, particularly malicious code. However, honeypots are a supplement to, not a replacement for, properly securing networks, systems and applications. If honeypots are to be used by an organization, qualified incident handlers and intrusion detection analysts should manage them. The other choices do not provide indications of potential attacks.
NEW QUESTION # 545
A trojan horse simply cannot operate autonomously.
- A. false
- B. true
Answer: B
Explanation:
Section: Protection of Information Assets
Explanation:
As a common type of Trojan horses, a legitimate software might have been corrupted with malicious code which runs when the program is used. The key is that the user has to invoke the program in order to trigger the malicious code. In other words, a trojan horse simply cannot operate autonomously. You would also want to know that most but not all trojan horse payloads are harmful - a few of them are harmless.

NEW QUESTION # 549
Which of the following findings should be of GREATEST concern to an IS auditor performing a review of IT operations?
- A. Operations shift turnover logs are not utilized to coordinate and control the processing environment
- B. The job scheduler application has not been designed to display pop-up error messages.
- C. Access to the job scheduler application has not been restricted to a maximum of two staff members
- D. Changes to the job scheduler application's parameters are not approved and reviewed by an operations supervisor
Answer: D
Explanation:
Changes to the job scheduler application's parameters are not approved and reviewed by an operations supervisor. This is a serious control weakness that could compromise the integrity, availability, and security of the IT operations. An IS auditor should be concerned about the lack of oversight and accountability for such changes, which could result in unauthorized, erroneous, or malicious modifications that affect the processing environment. The other options are less critical issues that may not have a significant impact on the IT operations. References:

NEW QUESTION # 555
Hamid needs to shift users from using the application from the existing (Old) system to the replacing (new)
system. His manager Lily has suggested he uses an approach in which the newer system is changed over
from the older system on a cutoff date and time and the older system is discontinued once the changeover
to the new system takes place. Which of the following changeover approach is suggested by Lily?
- A. Phased changeover
- B. Pilot changeover
- C. Parallel changeover
- D. Abrupt changeover
Answer: D
Explanation:
Section: Information System Acquisition, Development and Implementation
Explanation/Reference:
In the abrupt changeover approach the newer system is changed over from the older system on a cutoff
date and time, and the older system is discontinued once changeover to the new system takes place.
Changeover refers to an approach to shift users from using the application from the existing (old) system to
the replacing (new) system.
Changeover to newer system involves four major steps or activities
Conversion of files and programs; test running on test bed
Installation of new hardware, operating system, application system and the migrated data.
Training employees or user in groups
Scheduling operations and test running for go-live or changeover
Some of the risk areas related to changeover includes:
Asset safeguarding
Data integrity
System effectiveness
Change management challenges
Duplicate or missing records
The following were incorrect answers:
Parallel changeover - This technique includes running the old system, then running both the old and new
systems in parallel and finally full changing over to the new system after gaining confidence in the working
of new system.
Phased Changeover -In this approach the older system is broken into deliverables modules. Initially, the
first module of older system is phased out using the first module of a new system. Then, the second
module of the newer system is phased out, using the second module of the newer system and so forth until
reaching the last module.
Pilot changeover - Not a valid changeover type.
