Q651. Which of the following results in datacenters with failed humidity controls? (Select TWO).
A. Excessive EMI
B. Electrostatic charge
C. Improper ventilation
D. Condensation
E. Irregular temperature
Answer: B,D
Explanation:
Humidity control prevents the buildup of static electricity in the environment. If the humidity drops much below 50 percent, electronic components are extremely vulnerable to damage from electrostatic shock. Most environmental systems also regulate humidity; however, a malfunctioning system can cause the humidity to be almost entirely extracted from a room. Make sure that environmental systems are regularly serviced. Electrostatic damage can occur when humidity levels get too low. Condensation is a direct result from failed humidity levels.
Q652. Pete, the system administrator, is reviewing his disaster recovery plans. He wishes to limit the downtime in the event of a disaster, but does not have the budget approval to implement or maintain an offsite location that ensures 99.99% availability. Which of the following would be Pete’s BEST option?
A. Use hardware already at an offsite location and configure it to be quickly utilized.
B. Move the servers and data to another part of the company’s main campus from the server room.
C. Retain data back-ups on the main campus and establish redundant servers in a virtual environment.
D. Move the data back-ups to the offsite location, but retain the hardware on the main campus for redundancy.
Answer: A
Explanation:
A warm site provides some of the capabilities of a hot site, but it requires the customer to do more work to become operational. Warm sites provide computer systems and compatible media capabilities. If a warm site is used, administrators and other staff will need to install and configure systems to resume operations. For most organizations, a warm site could be a remote office, a leased facility, or another organization with which yours has a reciprocal agreement. Warm sites may be for your exclusive use, but they don’t have to be. A warm site requires more advanced planning, testing, and access to media for system recovery. Warm sites represent a compromise between a hot site, which is very expensive, and a cold site, which isn’t preconfigured.

Q655. Jane, an individual, has recently been calling various financial offices pretending to be another person to gain financial information. Which of the following attacks is being described?
A. Phishing
B. Tailgating
C. Pharming
D. Vishing
Answer: D
Explanation:
Vishing (voice or VoIP phishing) is an electronic fraud tactic in which individuals are tricked into revealing critical financial or personal information to unauthorized entities. Vishing works like phishing but does not always occur over the Internet and is carried out using voice technology. A vishing attack can be conducted by voice email, VoIP (voice over IP), or landline or cellular telephone. The potential victim receives a message, often generated by speech synthesis, indicating that suspicious activity has taken place in a credit card account, bank account, mortgage account or other financial service in their name. The victim is told to call a specific telephone number and provide information to "verify identity" or to "ensure that fraud does not occur." If the attack is carried out by telephone, caller ID spoofing can cause the victim's set to indicate a legitimate source, such as a bank or a government agency.
Vishing is difficult for authorities to trace, particularly when conducted using VoIP. Furthermore, like many legitimate customer services, vishing scams are often outsourced to other countries, which may render sovereign law enforcement powerless.
Consumers can protect themselves by suspecting any unsolicited message that suggests they are targets of illegal activity, no matter what the medium or apparent source. Rather than calling a number given in any unsolicited message, a consumer should directly call the institution named, using a number that is known to be valid, to verify all recent activity and to ensure that the account information has not been tampered with.
