Questions 4

Refer to the exhibit.

You are managing a FortiSwitch 3032E that is managed by FortiLink on a FortiGate 3960E. The 3032E is heavily utilized and there is only one port free.

The requirement is to add an additional three FortiSwitch 448E devices with 10Gbps SFP+ connectivity directly to the 3032E. The plan is to use split port (phy-mode) with QSFP28 mode to connect the new 448E switches.

In this scenario, which statement about the switch deployment is correct?

Options:

A.

Additional ports on Switch 1 can be split for a maximum of 128 interfaces.

B.

The port most of Switch 1 must be changed to QSFP.

C.

After enabling split ports and rebooting Switch 1, the new ports can be configured from the FortiGate.

D.

Switches 2-4 will connect successfully with Switch 1 split port in QSFP28 mode.

Questions 6

You are migrating the branches of a customer to FortiGate devices. They require independent routing tables on the LAN side of the network.

After reviewing the design, you notice the firewall will have many BGP sessions as you have two data centers (DC) and two ISPs per DC while each branch is using at least 10 internal segments.

Based on this scenario, what would you suggest as the more efficient solution, considering that in the future the number of internal segments, DCs or internet links per DC will increase?

Options:

A.

No change in design is needed as even small FortiGate devices have a large memory capacity.

B.

Acquire a FortiGate model with more capacity, considering the next 5 years growth.

C.

Implement network-id, neighbor-group and increase the advertisement-interval

D.

Redesign the SD-WAN deployment to only use a single VPN tunnel and segment traffic using VRFs on BGP
