9. What is a rogue wireless hotspot?
- It is a hotspot that was set up with outdated devices.
- It is a hotspot that does not encrypt network user traffic.
- It is a hotspot that does not implement strong user authentication mechanisms.
- It is a hotspot that appears to be from a legitimate business but was actually set up by someone without the permission from the business.
D. A rogue wireless hotspot is a wireless access point running in a business or an organization without the official permission from the business or organization.
10. What is a potential risk when using a free and open wireless hotspot in a public location?
- Too many users trying to connect to the Internet may cause a network traffic jam.
- The Internet connection can become too slow when many users access the wireless hotspot.
- Network traffic might be hijacked and information stolen.
- Purchase of products from vendors might be required in exchange for the Internet access.
Explanation: Many free and open wireless hotspots operate with no authentication or weak authentication mechanisms. Attackers could easily capture the network traffic in and out of such a hotspot and steal user information. In addition, attackers might set up a “rogue” wireless hotspot to attract unsuspecting users to it and then collect information from those users.
11. How does a security information and event management system (SIEM) in a SOC help the personnel fight against security threats?
- by integrating all security devices and appliances in an organization
- by analyzing logging data in real time
- by combining data from multiple technologies

A security information and event management system (SIEM) combines data from multiple sources to help SOC personnel collect and filter data, detect and classify threats, analyze and investigate threats, and manage resources to implement preventive measures.
12. Which statement best describes a motivation of hacktivists?
- They are part of a protest group behind a political cause.
- They are curious and learning hacking skills.
- They are trying to show off their hacking skills.
- They are interested in discovering new exploits.
Each type of cybercriminal has a distinct motivation for his or her actions.
13. If a SOC has a goal of 99.999% uptime, how many minutes of downtime a year would be considered within its goal?
- Approximately 5 minutes per year.
- Approximately 10 minutes per year.
- Approximately 20 minutes per year.
- Approximately 30 minutes per year.
Within a year, there are 365 days x 24 hours a day x 60 minutes per hour = 525,600 minutes. With the goal of uptime 99.999% of time, the downtime needs to be controlled under 525,600 x (1-0.99999) = 5.256 minutes a year.
14. Why do IoT devices pose a greater risk than other computing devices on a network?
- Most IoT devices do not require an Internet connection and are unable to receive new updates.
- IoT devices cannot function on an isolated network with only an Internet connection.
- Most IoT devices do not receive frequent firmware updates.
- IoT devices require unencrypted wireless connections.
IoT devices commonly operate using their original firmware and do not receive updates as frequently as laptops, desktops, and mobile platforms.
15. Which two services are provided by security operations centers? (Choose two.)
- managing comprehensive threat solutions
- ensuring secure routing packet exchanges
- responding to data center physical break-ins
- monitoring network security threats
- providing secure Internet connections
Security operations centers (SOCs) can provide a broad range of services to defend against threats to information systems of an organization. These services include monitoring threats to network security and managing comprehensive solutions to fight against threats. Ensuring secure routing exchanges and providing secure Internet connections are tasks typically performed by a network operations center (NOC). Responding to facility break-ins is typically the function and responsibility of the local police department.
16. Users report that a database file on the main server cannot be accessed. A database administrator verifies the issue and notices that the database file is now encrypted.
