Q191. An insurance company requires an account recovery process so that information created by an employee can be accessed after that employee is no longer with the firm. Which of the following is the BEST approach to implement this process?
A. Employee is required to share their password with authorized staff prior to leaving the firm
B. Passwords are stored in a reversible form so that they can be recovered when needed
C. Authorized employees have the ability to reset passwords so that the data is accessible
D. All employee data is exported and imported by the employee prior to them leaving the firm
Answer: C
Explanation:
Since a user’s password isn’t stored on most operating systems (only a hash value is kept), most operating systems allow the administrator (or authorized person in this case) to change the value then the information/files/documents can be accessed. This is the safest way of recovery by an authorized person and is not dependent on those who leave the firm.
Q192. Which of the following protocols is used by IPv6 for MAC address resolution?
A. NDP
B. ARP
C. DNS
D. NCP
Answer: A
Explanation:
The Neighbor Discovery Protocol (NDP) is a protocol in the Internet protocol suite used with Internet Protocol Version 6 (IPv6).
Q193. After a recent breach, the security administrator performs a wireless survey of the corporate network. The security administrator notices a problem with the following output:
MAC SSID ENCRYPTION POWER BEACONS
00:10:A1:36:12:CC MYCORP WPA2 CCMP 60 1202
00:10:A1:49:FC:37 MYCORP WPA2 CCMP 70 9102
FB:90:11:42:FA:99 MYCORP WPA2 CCMP 40 3031
00:10:A1:AA:BB:CC MYCORP WPA2 CCMP 55 2021 00:10:A1:FA:B1:07 MYCORP WPA2 CCMP 30 6044
Given that the corporate wireless network has been standardized, which of the following attacks is underway?
A. Evil twin
B. IV attack
C. Rogue AP
D. DDoS
Answer: A
Explanation:
The question states that the corporate wireless network has been standardized. By ‘standardized’ it means the wireless network access points are running on hardware from the same vendor. We can see this from the MAC addresses used. The first half of a MAC address is vendor specific. The second half is network adapter specific. We have four devices with MAC addresses that start with 00:10:A1. The “odd one out” is the device with a MAC address starting FB:90:11. This device is from a different vendor. The SSID of the wireless network on this access point is the same as the other legitimate access points. Therefore, the access point with a MAC address starting FB:90:11 is impersonating the corporate access points. This is known as an Evil Twin.
An evil twin, in the context of network security, is a rogue or fake wireless access point (WAP) that appears as a genuine hotspot offered by a legitimate provider. In an evil twin attack, an eavesdropper or hacker fraudulently creates this rogue hotspot to collect the personal data of unsuspecting users. Sensitive data can be stolen by spying on a connection or using a phishing technique. For example, a hacker using an evil twin exploit may be positioned near an authentic Wi-Fi access point and discover the service set identifier (SSID) and frequency. The hacker may then send a radio signal using the exact same frequency and SSID. To end users, the rogue evil twin appears as their legitimate hotspot with the same name. In wireless transmissions, evil twins are not a new phenomenon. Historically, they were known as honeypots or base station clones. With the advancement of wireless technology and the use of wireless devices in public areas, it is very easy for novice users to set up evil twin exploits.
Q194. A Windows-based computer is infected with malware and is running too slowly to boot and run a malware scanner. Which of the following is the BEST way to run the malware scanner?
A. Kill all system processes
B. Enable the firewall
C. Boot from CD/USB
D. Disable the network connection
Answer: C
Explanation:
Q195. Two members of the finance department have access to sensitive information. The company is concerned they may work together to steal information. Which of the following controls could be implemented to discover if they are working together?
A. Least privilege access
B. Separation of duties
C. Mandatory access control
D. Mandatory vacations
Answer: D
Explanation:
A mandatory vacation policy requires all users to take time away from work to refresh. Mandatory vacation give the employee a chance to refresh, but it also gives the company a chance to make sure that others can fill in any gaps in skills and satisfies the need to have replication or duplication at all levels. Mandatory vacations also provide an opportunity to discover fraud. In this case mandatory vacations can prevent the two members from colluding to steal the information that they have access to.
Q196. Which of the following should be connected to the fire alarm system in order to help prevent the spread of a fire in a server room without data loss to assist in an FM-200 deployment?
A. Water base sprinkler system
B. Electrical
C. HVAC
D. Video surveillance
Answer: C
Explanation:
HVAC refers to heating, ventilation and air-conditioning to allow for a zone-based environmental control measure. The fire-alarm system should ideally also be hooked up to the HVAC so that the HVAC can monitor the changes in heating and ventilation.
Q197. Which of the following is a best practice for error and exception handling?
A. Log detailed exception but display generic error message
B. Display detailed exception but log generic error message
C. Log and display detailed error and exception messages
D. Do not log or display error or exception messages
Answer: A
Explanation:
A detailed explanation of the error is not helpful for most end users but might provide information that is useful to a hacker. It is therefore better to display a simple but helpful message to the end user and log the detailed information to an access-restricted log file for the administrator and programmer who would need as much information as possible about the problem in order to rectify it.
Q198. Mike, a security professional, is tasked with actively verifying the strength of the security controls on a company’s live modem pool. Which of the following activities is MOST appropriate?
A. War dialing
B. War chalking
C. War driving
D. Bluesnarfing
Answer: A
Explanation:
War dialing is a technique of using a modem to automatically scan a list of telephone numbers, usually dialing every number in a local area code to search for computers, Bulletin board systems and fax machines. Hackers use the resulting lists for various purposes: hobbyists for exploration, and crackers - malicious hackers who specialize in computer security - for guessing user accounts (by capturing voicemail greetings), or locating modems that might provide an entry-point into computer or other electronic systems. It may also be used by security personnel, for example, to detect unauthorized devices, such as modems or faxes, on a company's telephone network.
Q199. An organization has three divisions: Accounting, Sales, and Human Resources. Users in the Accounting division require access to a server in the Sales division, but no users in the Human Resources division should have access to resources in any other division, nor should any users in the Sales division have access to resources in the Accounting division. Which of the following network segmentation schemas would BEST meet this objective?
A. Create two VLANS, one for Accounting and Sales, and one for Human Resources.
B. Create one VLAN for the entire organization.
C. Create two VLANs, one for Sales and Human Resources, and one for Accounting.
D. Create three separate VLANS, one for each division.
Answer: D
Explanation:
Q200. Which of the following is an attack vector that can cause extensive physical damage to a datacenter without physical access?
A. CCTV system access
B. Dial-up access
C. Changing environmental controls
D. Ping of death
Answer: C
Explanation:
Environmental systems include heating, air conditioning, humidity control, fire suppression, and power systems. All of these functions are critical to a well-designed physical plant. A computer room will typically require full-time environmental control. Changing any of these controls (when it was set to its optimum values) will result in damage.
