NSE8_812 Online Practice Questions

Explanation:
The prefix list in the exhibit is configured to match prefixes that are either in the 172.16.204.0/24 subnet or in the 172.62.0.0/16 subnet. The routes that match these prefixes will be active in the
routing table on the HQ firewall.
The routes that match the following prefixes will not be active in the routing table:

Explanation:
The customer's SSLVPN Portal is currently configured to use a self-signed certificate. This means that
the certificate is not trusted by any browsers, and users will have to accept a security warning before they can connect to the portal.
To resolve this issue, the customer needs to configure the FortiGate to use a Let's Encrypt certificate. Let's Encrypt is a free certificate authority that provides trusted certificates for websites and other applications.
The configuration change in option B will configure the FortiGate to use a Let's Encrypt certificate for the SSLVPN Portal. This will allow users to connect to the portal without having to accept a security warning.
The other configuration changes are not necessary to resolve the issue. Option A will configure the FortiGate to use a different port for the SSLVPN Portal, but this will not resolve the issue with the self-signed certificate. Option C will configure the FortiGate to use a different DNS name for the SSLVPN Portal, but this will also not resolve the issue with the self-signed certificate. Option D will configure the FortiGate to use a different certificate authority for the SSLVPN Portal, but this will also not resolve the issue because the customer still needs to use a trusted certificate.

Explanation:
D. The administrator must first manually map the interface for each device with a meta field.
The Jinja template in the exhibit is expecting a meta field called WAN to be set on the managed FortiGate. This meta field will specify which interface on the FortiGate should be assigned the "WAN" role. If the meta field is not set, then the template will fail.
E. The template will fail because this configuration can only be applied with a CLI or TCL script.
The Jinja template in the exhibit is trying to configure the interface role on the managed FortiGate. This type of configuration can only be applied with a CLI or TCL script. The Jinja template will fail
because it is not a valid CLI or TCL script.

Explanation:
The default load balancing mode for the SD-WAN implicit rule is source IP based. This means that traffic will be load balanced evenly between the overlay members, regardless of the member's priority.
To prevent traffic from being load balanced, you can configure the priority of each overlay member to 10. This will make the member ineligible for load balancing.
The other options are not correct. Changing the load balancing mode to source-IP based will still result in traffic being load balanced. Creating a new static route with the internet sdwan-zone only will not affect the load balancing of the overlay interface. Configuring the cost in each overlay member to 10 will also not affect the load balancing, as the cost is only used when the implicit rule cannot find a match for the destination IP address.

Explanation:
Option B: Adding more web servers to the real server pool will increase the overall capacity of the load balancer, which should help to resolve the issue of users not being able to access the website. Option D: Adding a connection-pool to the FortiADC virtual server will allow the load balancer to cache connections to the web servers, which can help to improve performance and reduce the number of dropped connections.
Option A: Changing the persistence rule to LB_PERSIS_SSL_SESSJD would only be necessary if the current persistence rule is not working properly. In this case, the CPU usage on the FortiADC and the web servers is low, so the persistence rule is likely not the issue.
Option C: Disabling SSL between the FortiADC and the web servers would reduce the load on the FortiADC, but it would also make the website less secure. Since the bandwidth utilization is under 30%, it is unlikely that disabling SSL would resolve the issue.
