NEW QUESTION # 19
You configured a Firebox for a school environment. Students must have more restricted access than teachers, and unauthenticated users cannot have any Internet access. You added Student and Teacher groups to your proxy policies that handle web traffic. Based on the image below, this configuration can accomplish your goals.
Answer: A
Explanation:
The image shows a configuration for a school environment with separateHTTPandHTTPS proxy policiesfor StudentsandTeachers. This separation allows for different levels of access control based on group membership, providing more restrictive access for students compared to teachers.
* Studentsare restricted by specific HTTP and HTTPS proxy policies, limiting their access to designated content and sites.
* Teachershave their own policies, which can be configured with more permissive rules.
* Unauthenticated users are not included in any policy, effectively blocking their internet access, as the firewall denies traffic not explicitly allowed by a policy.
This configuration meets the requirements by:
* Allowing teachers and students access as per their respective policies.
* Blocking unauthenticated users from internet access entirely.
NEW QUESTION # 20
If you have only one public IP address, can you use Static NAT to enable inbound connections to both an email server and a web server on the private network? (Select one.)
Answer: A
Explanation:
With only one public IP address, you can still configure Static NAT to route connections to both an email server and a web server, as long as each service is accessed on a different port. For instance, HTTP/HTTPS traffic for the web server can use port 80/443, while the email server can use ports associated with email protocols (e.g., 25 for SMTP). Static NAT can direct incoming requests to different internal servers based on port, making this approach feasible.
NEW QUESTION # 21
As you troubleshoot a Branch Office VPN tunnel, you see the log message below. Which settings can you modify in the BOVPN virtual interface configuration to resolve this issue? (Select one.) (Log message: msg='iprocess: SA Proposal mismatch on Phase 2 negotiation')
Answer: B
Explanation:
Comprehensive Technical Explanation:
IPSec VPN negotiations execute across two sequential phases: Phase 1 (Internet Key Exchange / IKE SA) authenticates the remote endpoints and builds a secure control channel, while Phase 2 (IPSec Quick Mode / Child SA) negotiates the cryptographic parameters and Security Associations (SAs) used to encapsulate and protect user data payloads.
When Traffic Monitor records a log event stating 'SA Proposal mismatch on Phase 2 negotiation', it confirms that Phase 1 authentication completed successfully, but the endpoints failed to agree on Phase 2 parameters. In a BOVPN Virtual Interface configuration, Phase 2 settings define the data encapsulation protocol (ESP), the encryption cipher (e.g., AES-GCM, AES-CBC 256), the authentication/hash algorithm (e.g., SHA2-256), and whether Perfect Forward Secrecy (PFS) is required. Both VPN endpoints must have matching Phase 2 proposal parameters. Modifying the Phase 2 Settings on the Firebox to match the remote third-party gateway's proposal parameters resolves the negotiation failure.

NEW QUESTION # 22
After you enable content inspection, your users see a certificate warning when they browse the Internet. What is one way to resolve this? (Select one.)
Answer: B
Explanation:
Comprehensive Technical Explanation:
When HTTPS Content Inspection (deep packet inspection) is enabled within an HTTPS-proxy action, the Firebox intercepts outbound TLS handshakes. It establishes an independent secure session with the requested destination web server, re-encrypts the inspected payload, and presents a dynamically generated substitute certificate to the requesting client workstation. This substitute certificate is cryptographically signed by the Firebox's internal Certificate Authority, known as the Proxy Authority CA certificate.
Because
endpoint client operating systems and web browsers maintain their own trusted root CA stores, they flag any dynamic certificate issued by an untrusted issuer as invalid, triggering untrusted certificate authority warning banners. To eliminate these warnings, administrators must export the Proxy Authority certificate from the Firebox and distribute it to all client endpoints, installing it into their local operating system and browser Trusted Root Certification Authorities stores. This distribution can be accomplished using Active Directory Group Policy Objects (GPO), MDM software, or by directing users to download it directly from the Firebox Certificate Portal (http://
< Firebox-IP > :4126/certportal).

NEW QUESTION # 23
There is an Internet outage at your primary ISP, but the Internet connection from the Firebox has not failed over to your backup ISP. Both ISP connectors are correctly cabled and have active physical links. What could cause this problem? (Select two.)
Answer: A,D
Explanation:
Comprehensive Technical Explanation:
Multi-WAN automatic failover on a Firebox relies on the Link Monitor service to assess WAN connection health beyond basic physical link-carrier detection. Two primary configuration issues can prevent failover during an ISP outage:
1. Target selection behind an upstream fault: If the Link Monitor target for the primary WAN interface is configured to ping only the ISP's local default gateway router, that local hop may continue answering ARP and ICMP requests even if the provider's upstream links are down. Because the gateway continues responding, the Firebox considers the primary interface healthy and does not trigger failover (Option B).
2. Unresponsive backup target: If the Link Monitor target for the backup ISP interface fails to respond (e.g., an invalid target IP, ISP routing issue, or blocked ICMP/TCP probe), the Firebox considers the backup interface inactive. As a result, it will not route traffic to an interface marked down (Option A).
Secondary IP configurations (Option C) are not required for Multi-WAN failover. Fallback modes (Options D and E) dictate how connections return to the primary link after recovery rather than how failover is triggered during an outage.
