Question 6 of 65

Which method do VPNs use to prevent outside parties from viewing packets in clear text?

Answer

Suggested Answer

The suggested answer is C.

VPNs use encryption to prevent outside parties from viewing packets in clear text. Encryption converts the data into a format that is unreadable by anyone who does not have the decryption key, ensuring that the transmitted information remains confidential and secure.

Question 7 of 65

What is the correct order of processing when configuring NAT rules and security policies?

Answer

Suggested Answer

The suggested answer is A.

The correct order for processing when configuring NAT rules and security policies is: destination NAT, policy lookup, source NAT, and then static NAT. Destination NAT needs to occur before policy lookup because the destination address might be changed before determining which policy applies. After policy lookup, source NAT is applied as it generally involves modifying the packet before it leaves the router. Static NAT, which typically involves a one-to-one mapping, occurs last.

Question 8 of 65

Which two statements describe IPsec VPNs? (Choose two.)

Answer

Suggested Answer

The suggested answer is A, D.

IPsec VPN traffic is always authenticated, ensuring that the data being transferred is protected from tampering and impersonation. IPsec VPNs use security measures to secure traffic over a public network between two remote sites, making it a widely used method for creating secure connections over the internet.

Question 9 of 65

Which zone is considered a functional zone?

Answer

Suggested Answer

The suggested answer is D.

A functional zone is a special type of zone used for specific purposes such as managing traffic for administration interfaces. In the context of Juniper network devices, the Management (MGT) zone is a functional zone. It is meant for management interfaces and ensures that management traffic does not conflict with regular data traffic. Therefore, the Management zone is rightly considered a functional zone.

Question 10 of 65

What does IPsec use to negotiate encryption algorithms?

Answer

Suggested Answer

The suggested answer is C.

IPsec uses the Internet Key Exchange (IKE) protocol to negotiate encryption algorithms. IKE facilitates the creation of a secure and authenticated channel by negotiating the security associations (SAs) used for the IPsec connection. AH provides integrity but not encoding, TLS is used for secure web communications, and ESP is used to encrypt and authenticate the IPsec packets but does not handle the negotiation of the encryption algorithms.
