Module 4 Quiz

1. Which of the following statements about Network Address Translation (NAT) are true? Each correct answer represents a complete solution. Choose two. A. It allows the computers in a private network to share a global, ISP assigned address to connect to the Internet. B. It provides added security by using Internet access to deny or permit certain traffic from the Bastion Host. C. It allows external network clients access to internal services. D. It reduces the need for globally unique IP addresses.

2. Mark works as a Network Administrator for TechMart Inc. The company has a Windows-based network. Mark wants to implement a method to ensure that the mobile devices are in a good state of security health when they are trying to access the corporate network. Which of the following is a control or strategy that Mark will implement to assure the security health? A. TCP/IP protocol B. B. Kerberos C. C. Single Sign On D. D. Network Access Protection

3. Which of the following are the uses of Network Access Protection (NAP)? Each correct answer represents a complete solution. Choose all that apply. A. It is used to protect against virus. B. It is used to verify the complete integrity of each device. C. It permits a user to access all computers and systems where he got a access permission, without entering passwords for multiple times D. It is used to authenticate a request for a service in a computer network.

4. Which of the following services does IPSec provide for protecting data? Each correct answer represents a complete solution. Choose two. A. Network authentication B. Encryption C. Data authentication D. Compression

5. Which of the following functions are performed by a firewall? Each correct answer represents a complete solution. Choose all that apply. A. It blocks unwanted traffic. B. It hides vulnerable computers that are exposed to the Internet. C. It enhances security through various methods, including packet filtering, circuitlevel filtering, and application filtering. D. It logs traffic to and from the private network.

6. Which of the following is the layer in which encryption and decryption of data takes place? A. Presentation layer B. Session layer C. Physical layer D. Data-link layer

7. Mark work as a System Administrator for TechMart Inc. The company has a Windows- based network. Mark wants to allow the remote travel agents to be able to access the corporate network so that they are free to check and post appointments that are booked for the particular day. Mark has decided to permit the travel agents to use their home computers but he is required to be assured that the information is not compromised by anyone because the security of client information is on the top priority for him. Mark is concerned about probable attackers will be able to penetrate the VPN. Which of the following will Mark use to attract the attackers for understanding their methods? A. CIA Triangle B. Attack surface. C. Honeypot D. Social engineering

8. Which of the following works at the network layer and hides the local area network IP address and topology? A. Network address translation (NAT) B. MAC address C. Hub D. Network interface card (NIC)

9. Which of the following protects against unauthorized access to confidential information via encryption and works at the network layer? A. Firewall B. NAT C. IPSec D. MAC address
