Question No. 1

Refer to the exhibit.

A FortiWeb appliance is configured for load balancing web sessions to internal web servers. The Server Pool is configured as shown in the exhibit.

How will the sessions be load balanced between server 1 and server 2 during normal operation?

Show Answer Hide Answer
Correct Answer: A

The Server Pool in the exhibit is configured with a weight of 20 for server 1 and a weight of 60 for server 2. This means that server 1 will receive 20% of the sessions and server 2 will receive 75% of the sessions.

The following formula is used to calculate the load balancing between servers in a Server Pool:

weight_of_server_1 / (weight_of_server_1 + weight_of_server_2)

In this case, the formula is:

20 / (20 + 60) = 20 / 80 = 0.25 = 25%

Therefore, server 1 will receive 25% of the sessions and server 2 will receive 75% of the sessions.

Question No. 3

Refer to the exhibits.

A customer has deployed a FortiGate with iBGP and eBGP routing enabled. HQ is receiving routes over eBGP from ISP 2; however, only certain routes are showing up in the routing table-Assume that BGP is working perfectly and that the only possible modifications to the routing table are solely due to the prefix list that is applied on HQ.

Given the exhibits, which two routes will be active in the routing table on the HQ firewall? (Choose two.)

Show Answer Hide Answer
Correct Answer: A, D

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:

172.16.201.96/29

172.62.0.64/27

These routes do not match the criteria set by the prefix list.

Question No. 4

Refer to the exhibits.

The exhibits show a diagram of a requested topology and the base IPsec configuration.

A customer asks you to configure ADVPN via two internet underlays. The requirement is that you use one interface with a single IP address on DC FortiGate.

In this scenario, which feature should be implemented to achieve this requirement?

Show Answer Hide Answer
Correct Answer: A

A is correct because using network-overlay id allows you to configure multiple ADVPN tunnels on a single interface with a single IP address on the DC FortiGate. This is explained in the FortiGate Administration Guide under ADVPN > Configuring ADVPN > Configuring ADVPN on the hub.

Question No. 5

You are creating the CLI script to be used on a new SD-WAN deployment You will have branches with a different number of internet connections and want to be sure there is no need to change the Performance SLA configuration in case more connections are added to the branch.

The current configuration is:

Which configuration do you use for the Performance SLA members?

Show Answer Hide Answer
Correct Answer: A

The set members any option will ensure that all of the SD-WAN interfaces are included in the Performance SLA. This is the best option if you want to be sure that the Performance SLA will be triggered even if more connections are added to the branch in the future.

The set members 0 option will exclude all of the SD-WAN interfaces from the Performance SLA. This is not a good option because it will prevent the Performance SLA from being triggered even if there is a problem with the network.

The current configuration already fulfills the requirement option is incorrect because it does not ensure that all of the SD-WAN interfaces will be included in the Performance SLA.

The set members all option will include all of the SD-WAN interfaces in the Performance SLA, but it is not the best option because it is not scalable. If you have a large number of SD-WAN interfaces, this option will cause the Performance SLA to be triggered too often.
