Increased data storage capacity
Reduced need for encryption methods
Faster data processing speeds
2. What is the name of the technology used to monitor and restrict employee
access to certain websites?
Firewall
Intrusion detection system
VPN
Web filtering
3. Your company wants to ensure that their information is secure. They insist that
when out of the office you only access company systems in a secure and
encrypted manner over the Internet. What is the method they want you to
use?
Using a user ID and password
Through a VPN
Through an IP protocol
Using TCP
Through a firewall
,4. If an organization experiences a data breach, which technology would be
most effective in analyzing the network traffic to identify the source of the
breach?
Access control mechanisms
Data encryption software
User authentication systems
Intrusion detection system
5. Which of the following data security methods protects information by
obscuring specific areas of data with random characters or codes?
Data access control
Data masking
Data encryption
Data retention
6. What is the term used for restricting access to certain areas based on job
roles?
User authentication
Encryption methods
Intrusion detection
Access controls
7. Describe how encryption protects sensitive information during transmission
over the internet.
Encryption is a method to store data securely on a hard drive.
, Encryption transforms data into a secure format that can only be
read by authorized parties, preventing unauthorized access during
transmission.
Encryption allows multiple users to access data simultaneously without
security risks.
Encryption compresses data to speed up transmission over the
internet.
8. If an organization is experiencing frequent data breaches during inter-office
communications, which security measure should they prioritize to enhance
data protection?
Conducting regular employee training on security policies
Upgrading hardware firewalls
Implementing encryption for all communications
Increasing physical security at office locations
9. A company must ensure sensitive data at rest is rendered unreadable. Which
of the following will the company most likely use?
Encryption
Segmentation
Tokenization
Hashing
10. What is the term for the security feature that filters incoming traffic based on
specific criteria such as protocol and port numbers?
Encryption
Firewall
, Intrusion Detection System
Access Control
11. Describe the purpose of a DMZ in network security.
A DMZ is used to create a buffer zone that separates an
organization's internal network from external threats while allowing
controlled access to critical servers.
A DMZ is a policy for user authentication and access control.
A DMZ is a secure method for encrypting data in transit.
A DMZ is a type of firewall that blocks all incoming traffic.
12. Describe how access controls contribute to the security of sensitive data in
an organization.
Access controls encrypt data to ensure it cannot be read by
unauthorized users.
Access controls limit data access to authorized users, thereby
protecting sensitive information from unauthorized access.
Access controls monitor network traffic for potential security
breaches.
Access controls create backups of sensitive data to prevent loss.
13. If an organization is experiencing frequent unauthorized access attempts,
which security measure should they implement to enhance their network
security?
Regular audits of user access logs.
An intrusion detection system to monitor and analyze network
traffic.
