Question 1

A company uses public key infrastructure for encryption and signing of emails. An employee wants to send a confidential message to a colleague. How should the employee send the message so that it's encrypted?

Correct Answer: Encrypt the message with the recipient's public key

To send an encrypted message using public key infrastructure, the sender should encrypt the message with the recipient's public key. This ensures that only the recipient, who holds the corresponding private key, can decrypt the message.

Question 2

A security analyst receives an email that appears to be from a trusted sender. After checking the email's properties, the analyst realizes it uses a slightly different domain name. Which attack method is being used?

Correct Answer: Spoofing

Spoofing occurs when an attacker pretends to be someone else by falsifying the sender's information. Typically, spoofing is done by using a slightly different domain name or email address to impersonate a trusted source.

Question 3

A network administrator needs to implement a secure method for remote employees to access internal resources. Which of the following is the BEST solution?

Correct Answer: VPN

A VPN (Virtual Private Network) provides a secure way for remote employees to access internal resources by creating an encrypted tunnel between their devices and the company network. FTP, Telnet, SMTP, SNMP, and HTTP are not protocols designed for secure remote access.
