Q
In SD-WAN configuration, what is the implicit rule?
A
- Created by default
- Always present at the bottom of the rule list
- If no user-defined routes are matched, the implicit rule is used
- By default, load balanced the traffic across all available members
2
Q
In an SD-WAN environment, what are underlays?
A
- Physical links provided by ISP
- Restricted routing
- No added security
- Cable, DSL, fiber, MPLS, 4G, LTE
3
Q
In an SD-WAN environment, what are overlays?
A
- Virtual links built on top of underlay links
- Flexible routing
- Enhanced security
- IPsec, GRE, IP-in-IP
4
Q
What does performance SLAs monitor for each member?
A
- State (alive/dead)
- Packet loss
- Latency
- Jitter
5
Q
When load balancing is activated in SD-WAN configuration, how is the traffic load balanced?
A
- Round-robin algorithm by default
- Can set other algorithms through CLI commands
6
Q
How do SD-WAN rules behave?
A
Like policy routes
7
Q
Why might a SD-WAN rule be skipped?
A
- Best route to destination isn’t an SD-WAN member
- None of the members have a valid route to the destination
8
Q
How can you view the policy route table?
A
- In CLI
- diagnose firewall proute list
9
Q
Which routes apply first? SD-WAN or regular policy routes?
A
Regular policy routes
