AZ-800 AZ-800 - Microsoft Azure Networking Solutions Load Balancer and Azure Front Door Questions and Answers 1 — Questions and Answers
Question 1: Which Azure Load Balancer SKU is required for zone-redundant frontend IP configurations?
- Basic
- Standard (Correct answer)
- Global
- Premium
Correct answer: Standard
Only the Standard SKU supports zone-redundant and zonal frontend IPs; the Basic SKU does not support Availability Zones.
Question 2: What is the default load-balancing algorithm used by Azure Load Balancer?
- Round robin
- Least connections
- 5-tuple hash (Correct answer)
- IP hash only
Correct answer: 5-tuple hash
Azure Load Balancer uses a 5-tuple hash (source IP, source port, destination IP, destination port, protocol) by default to distribute flows.
Question 3: Which Azure Front Door feature caches content at edge locations to reduce latency for static assets?
- WAF policies
- Health probes
- Rules Engine
- Azure CDN integration / built-in caching (Correct answer)
Correct answer: Azure CDN integration / built-in caching
Azure Front Door Standard and Premium have built-in content caching at edge PoPs that reduces origin load and response latency for static content.
Question 4: A backend VM must receive the real client IP address through an Azure Standard Load Balancer. What must you enable?
- Floating IP (Direct Server Return) (Correct answer)
- Session persistence
- HA Ports rule
- Accelerated networking
Correct answer: Floating IP (Direct Server Return)
Floating IP (Direct Server Return) preserves the original client IP in the packet, allowing the backend to see the true source address.
Question 5: Which Azure Front Door tier supports private origin connectivity via Private Link?
- Standard only
- Premium only (Correct answer)
- Both Standard and Premium
- Classic only
Correct answer: Premium only
Private Link origin connectivity is available only in the Azure Front Door Premium tier.
Question 6: What type of Azure Load Balancer rule distributes all ports and protocols with a single rule for high-availability appliances?
- NAT rule
- Outbound rule
- HA Ports rule (Correct answer)
- Probe rule
Correct answer: HA Ports rule
HA Ports rules (protocol=All, port=0) distribute all TCP/UDP flows across backend pool members, ideal for NVAs requiring failover.
