Answer : C

In Palo Alto Networks' Single-Pass Parallel Processing (SP3) architecture, SSL/TLS decryption occurs only during the slow path when the firewall first encounters a new session.

''SSL/TLS decryption, which requires CPU-intensive cryptographic operations, is performed during the slow path when establishing new sessions. Once decrypted, traffic is processed in the fast path for subsequent packets.''

After the initial decryption in the slow path, decrypted traffic is handled by fast path for efficiency.

Answer : B

To prevent SYN flood attacks, the NGFW uses SYN cookies to validate legitimate session establishment.

''SYN cookies allow the firewall to verify the legitimacy of new session requests without allocating resources until the handshake is completed. This prevents SYN flood attacks from exhausting system resources.''

SYN cookies mitigate resource exhaustion by ensuring only legitimate connections are established.

Answer : B

Client-based VPN solutions like GlobalProtect provide full coverage for the mobile workforce by extending the enterprise security stack to remote endpoints. It establishes a secure tunnel, allowing consistent security policies across the enterprise perimeter and the mobile workforce.

''GlobalProtect is a client-based VPN that provides secure, consistent protection for mobile users by extending the security capabilities of Prisma Access to remote endpoints, covering all network protocols.''

Answer : C

In cloud environments like Azure, the VM-Series NGFW is deployed to create Layer 3 segmentation zones closest to the application workloads.

''In Azure, deploy VM-Series firewalls in Layer 3 mode to enforce security policies closest to private applications, meeting strict compliance and segmentation requirements.''

Layer 3 segmentation ensures security policies are enforced at the right boundary to isolate traffic within Azure's virtual networks.

Answer : B, C

When implementing SSL Forward Proxy decryption for outbound traffic, two key challenges that must be evaluated are:

Incomplete certificate chains: This occurs when the firewall cannot validate the entire certificate chain for a site, which may cause decryption failures.

Certificate pinning: Applications like banking apps may use certificate pinning to prevent MITM (man-in-the-middle) attacks, and these applications will break if SSL Forward Proxy is used.

''When decrypting outbound SSL traffic, you must consider incomplete certificate chains, which can cause decryption to fail if the firewall cannot validate the entire chain. Also, be aware of certificate pinning in applications that prevents decryption by rejecting forged certificates.''
