Professional Cloud Network Engineer Practice Test

What this test covers

One concept per question, across the topics Professional Cloud Network Engineer draws on.

• Pass-through load balancing preserves the client source address and supports UDP
• Service perimeters address exfiltration by an authorised identity
• TTL determines how long resolvers cache an answer, so it must be lowered before a change
• Shared VPC centralises network control while devolving resource management
• Cache keys determine what counts as the same request
• Global HTTP(S) traffic with one anycast address means the global Application Load Balancer
• Firewall rules are evaluated by priority, lowest number first, and the first match wins
• VPC peering is non-transitive by design
• Cloud NAT provides outbound-only internet access for instances without public addresses
• Implied firewall rules deny all ingress and allow all egress
