1On a FortiGate, what is the minimum requirement before an interface can be added as an SD-WAN member?

A.The interface must have an IP address from a public range only

B.The interface must not be referenced by any existing firewall policy or static route

C.The interface must already be a member of a zone

D.The interface must be configured as a loopback

Explanation: An interface cannot be added as an SD-WAN member if it is still referenced by a firewall policy, static route, or as a source/destination interface elsewhere. You must first remove those references; only then can the interface be enrolled as an SD-WAN member, after which policies and routes are recreated against the SD-WAN zone.

2Which statement about SD-WAN zones in FortiOS 7.4 is correct?

A.Each SD-WAN member can belong to multiple zones simultaneously

B.An SD-WAN zone is a logical grouping of members used in firewall policies and static routes

C.Zones are mandatory only for IPv6 SD-WAN

D.A FortiGate supports a maximum of two zones, virtual-wan-link and overlay

Explanation: An SD-WAN zone is a logical grouping of one or more SD-WAN members. Firewall policies and static routes reference the zone, not individual members, which simplifies management when members change. The default zone is virtual-wan-link, but administrators can create additional zones such as underlay and overlay.

3Which performance SLA detection protocol on FortiOS 7.4 measures both forward and reverse latency from the FortiGate to the responder?

A.HTTP GET

B.Ping (ICMP echo)

C.DNS

D.Two-way (TWAMP)

Explanation: The two-way protocol uses TWAMP (RFC 5357) and requires a TWAMP responder, typically another FortiGate. It returns separate forward and reverse latency, jitter, and loss measurements, which is essential for asymmetric SD-WAN paths. HTTP, ICMP ping, and DNS only return round-trip values.

4An SD-WAN performance SLA is configured with `members 0`. What does this setting do?

A.It disables the SLA

B.It tests only the first member in the SD-WAN list

C.It probes every member of the SD-WAN interface

D.It uses zero-touch member discovery

Explanation: Setting `members 0` (or omitting the members list) tells the SLA to send probes through every SD-WAN member. To restrict the probe to specific members, list their member IDs explicitly under `config members`.

5In a performance SLA, what is the purpose of the `sla-fail-log-period` setting?

A.Defines how often a syslog event is generated while the SLA is in a failed state

B.Defines how long an SLA must be failing before it is considered down

C.Defines the retry interval for the next probe attempt

D.Defines the cooldown after recovery before logging stops

Explanation: `sla-fail-log-period` controls the cadence at which the FortiGate logs events while an SLA remains in the failed state, preventing log floods. The threshold for declaring failure is set with `failtime` and packet-loss/latency/jitter targets.

6Which CLI command displays per-member SLA performance values, including latency, jitter, and packet loss?

A.diagnose sys sdwan health-check

B.diagnose sys sdwan member

C.get system performance status

D.diagnose debug application sdwan -1

Explanation: `diagnose sys sdwan health-check` shows per-SLA, per-member latency, jitter, and packet-loss values along with the alive/dead state. `diagnose sys sdwan member` lists members and weights, while the debug command produces real-time event logs but not summarized health values.

7Which value does the FortiGate use as the default SD-WAN member weight?

A.0

B.1

C.10

D.100

Explanation: Each SD-WAN member starts with a default weight of 1. Weight matters when the implicit rule is set to source-dest-ip or source-ip-based load balancing, where higher weights receive proportionally more sessions.

8Which statement best describes the implicit SD-WAN rule on FortiOS 7.4?

A.It is matched only when no firewall policy applies

B.It is the catch-all rule used when no explicit SD-WAN rule matches a session

C.It always uses the lowest-cost strategy regardless of configuration

D.It cannot be edited

Explanation: The implicit rule is the default SD-WAN rule that handles traffic when no user-defined SD-WAN rule matches. Its load-balancing algorithm is configurable, including source-IP, source-dest-IP, sessions, spillover, measured-volume, and usage-based options.

9An SD-WAN rule uses Best Quality with latency as the quality metric. Which statement is true?

A.Only the member with the absolute lowest latency is ever used

B.The FortiGate selects the member with the lowest latency unless its latency is within the configured tolerance of another member

C.Best Quality requires a TWAMP responder

D.Best Quality ignores SLA failure states

Explanation: Best Quality (Best Quality - Performance SLA) selects the member with the best SLA value, but the FortiGate keeps using the current member as long as its quality stays within the configured tolerance percentage. Members in a failed SLA state are excluded from selection.

10A Lowest Cost (SLA) SD-WAN rule has three members with costs 10, 20, and 20, and all members are passing the SLA. Which member is selected?

A.The member with cost 10

B.The member with the lowest latency, regardless of cost

C.Round-robin across all three members

D.The first member listed in the rule, regardless of cost

Explanation: Lowest Cost (SLA) selects the eligible member with the lowest cost, where eligibility means it is currently meeting the bound performance SLA. Among ties, member order in the rule and weight break the tie. Latency does not break a cost difference.
