Q633. After an assessment, auditors recommended that an application hosting company should contract with additional data providers for redundant high speed Internet connections. Which of the following is MOST likely the reason for this recommendation? (Select TWO).
A. To allow load balancing for cloud support
B. To allow for business continuity if one provider goes out of business
C. To eliminate a single point of failure
D. To allow for a hot site in case of disaster
E. To improve intranet communication speeds
Answer: B,C
Explanation:
A high-speed internet connection to a second data provider could be used to keep an up-to-date replicate of the main site. In case of problem on the first site, operation can quickly switch to the second site. This eliminates the single point of failure and allows the business to continue uninterrupted on the second site. Note: Recovery Time Objective The recovery time objective (RTO) is the maximum amount of time that a process or service is allowed to be down and the consequences still be considered acceptable. Beyond this time, the break in business continuity is considered to affect the business negatively. The RTO is agreed on during BIA creation.

B. The company is using the wrong antenna type.
C. The MAC filtering is disabled on the access point.
D. The company is not using strong enough encryption.
Answer: A
Explanation:

Q636. A company wants to ensure that its hot site is prepared and functioning. Which of the following would be the BEST process to verify the backup datacenter is prepared for such a scenario?
A. Site visit to the backup data center
B. Disaster recovery plan review
C. Disaster recovery exercise
D. Restore from backup
Answer: C
Explanation:
A hot site is a location that can provide operations within hours of a failure. This type of site would have servers, networks, and telecommunications equipment in place to reestablish service in a short time. Hot sites provide network connectivity, systems, and preconfigured software to meet the needs of an organization. This means that an actual exercise run would test the abilities of your hot site best.
Q637. A user attempting to log on to a workstation for the first time is prompted for the following information before being granted access: username, password, and a four-digit security pin that was mailed to him during account registration. This is an example of which of the following?
A. Dual-factor authentication
B. Multifactor authentication
C. Single factor authentication
D. Biometric authentication
Answer: C

Multi-factor authentication (MFA) is a method of computer access control which a user can pass by successfully presenting authentication factors from at least two of the three categories: knowledge factors ("things only the user knows"), such as passwords possession factors ("things only the user has"), such as ATM cards inherence factors ("things only the user is"), such as biometrics
In this question a username, password, and a four-digit security pin knowledge are all knowledge factors (something the user knows). Therefore, this is single-factor authentication.
Q638. All executive officers have changed their monitor location so it cannot be easily viewed when passing by their offices. Which of the following attacks does this action remediate?
A. Dumpster Diving
B. Impersonation
C. Shoulder Surfing
D. Whaling
Answer: C
Explanation:
Viewing confidential information on someone’s monitor is known as shoulder surfing. By moving their monitors so they cannot be seen, the executives are preventing users passing by ‘shoulder surfing’.
Shoulder surfing is using direct observation techniques, such as looking over someone's shoulder, to get information. Shoulder surfing is an effective way to get information in crowded places because it's relatively easy to stand next to someone and watch as they fill out a form, enter a PIN number at an ATM machine, or use a calling card at a public pay phone. Shoulder surfing can also be done long distance with the aid of binoculars or other vision-enhancing devices. To prevent shoulder surfing, experts recommend that you shield paperwork or your keypad from view by using your body or cupping your hand.
