Additional Security+ questions to help you prepare for the new performance based questions. These are included with the full bank of Security+ practice test questions and are divided into different sections. For example, you'll have access to the following links:

- Performance Based Question - Set 1

You'll see a graphic explaining what you might be required to do on the actual exam to match different types of security to mobile devices and servers in a data center. You'll then have two questions that test your knowledge and ability to correctly answer the questions. This question also includes a link to a graphic showing the end solution for the overall performance based question simulation.

- Performance Based Question - Set 2

You'll see a graphic explaining what you might be required to do on the actual exam to match different types of attacks with the name of the attack type. You'll then have five questions that test your knowledge and ability to correctly answer the questions. This question also includes a link to a graphic showing the end solution for the overall performance based question simulation.

- Performance Based Question - Set 3

You'll see a graphic showing a network with computers and servers separated by a firewall. The firewall is used to control traffic between the computers and users using rules within an access control list (ACL).  You'll have three questions that test your knowledge and ability to correctly identify the relevant components of the rule. The incorrect answers and explanation provide you with insight into how to correctly answer this type of question on the actual exam.

- Performance Based Question - Set 4

You'll see a graphic explaining what you might be required to do on the actual exam related to what a forensic analyst would do during an investigation. You'll then have two questions that test your knowledge and ability to correctly answer the questions. This question also includes a link to a graphic showing the end solution for the overall performance based question simulation.

- Performance Based Question - Set 5

You'll see a graphic explaining what you might be required to do on the actual exam to match protocols and ports.

Security+ Encryption Practice Test Questions with Answers

Q1. Your network requires a secure method of sharing encryption keys over a public network. Which of the following is the BEST choice?

A. Symmetric encryption

B. Bcrypt

C. Diffie-Hellman

D. Steganography

Q1 Answer: C is correct. Diffie-Hellman allows entities to negotiate encryption keys securely over a public network.

Once the entities negotiate the keys, they use symmetric encryption, but they can’t share keys using symmetric encryption without first using a secure method such as Diffie-Hellman.

Bcrypt is a key stretching technique used by some Unix systems to make password cracking more difficult.

Steganography hides data within data, but it isn’t the best method of sharing encryption keys over a public network.

 

Q2. Bart wants to send a secure email to Lisa so he decides to encrypt it. Bart digitally signs it and wants to ensure that Lisa can verify that he sent it. Which of the following does Lisa need to meet this requirement?

A. Bart’s public key

B. Bart’s private key

C. Lisa’s public key

D. Lisa’s private key

Q2 Answer. A is correct. Lisa would decrypt the digital signature with Bart’s public key. The digital signature provides verification that Bart sent the message, non-repudiation, and integrity for the message.

Bart encrypts the digital signature with his private key, which can only be decrypted with his public key.

Lisa’s keys are not used for Bart’s digital signature, but might be used for the encryption of the email.

Although not part of this scenario, Bart would encrypt the email with Lisa’s public key and Lisa would decrypt the email with Lisa’s private key.

Q3. Bart wants to send a secure email to Lisa so he decides to encrypt it. Bart wants to ensure that Lisa can decrypt it. Which of the following does Lisa need to decrypt it?

A. Bart’s public key

B. Bart’s private key

C. Lisa’s public key

D. Lisa’s private key

Q3 Answer. D is correct. Lisa needs her private key to decrypt it.

Bart would encrypt the message with Lisa’s public key.

Bart encrypts the digital signature with his private key, which can only be decrypted with his public key.

Bart’s keys are not used for encrypting data that Lisa can decrypt.
