Question 370
The HPE AOS-CX switching case is: A WAN uplink has burst-sensitive traffic but an engineer installs an aggressive ingress policer on access ports. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)
Explanation
Correct Answers
The targeted correction for A WAN uplink has burst-sensitive traffic but an engineer installs an aggressive ingress policer on access ports is: Differentiate supported ingress policing from egress shaping and confirm rate controls fit the actual traffic direction and SLA. It reduces the risk that a policer applied in the wrong direction can drop desired traffic, while shaping on the wrong interface does not alleviate the bottleneck.
A separate operational validation for A WAN uplink has burst-sensitive traffic but an engineer installs an aggressive ingress policer on access ports is: Direction-specific traffic trials verify expected drop or smoothing behavior and preserve required business traffic. It proves intended behavior instead of accepting configuration presence alone.
Incorrect Answers
This alternative concerns egress scheduling queue mapping and congestion control; its associated risk is: Incorrect queue assignment and strict-priority overuse can cause starvation, loss and unstable latency under load. The observed case A WAN uplink has burst-sensitive traffic but an engineer installs an aggressive ingress policer on access ports requires the more specific qos policing shaping and trust verification control. The targeted action is: Differentiate supported ingress policing from egress shaping and confirm rate controls fit the actual traffic direction and SLA.
This alternative concerns dscp and cos classification trust boundaries; its associated risk is: Untrusted hosts can mark bulk flows as high priority and starve real-time applications during congestion. The observed case A WAN uplink has burst-sensitive traffic but an engineer installs an aggressive ingress policer on access ports requires the more specific qos policing shaping and trust verification control. The targeted action is: Differentiate supported ingress policing from egress shaping and confirm rate controls fit the actual traffic direction and SLA.
This alternative concerns running versus startup configuration and controlled save; its associated risk is: A working session can vanish after a restart, while inadvertently saved emergency settings can persist outside the change window. The observed case A WAN uplink has burst-sensitive traffic but an engineer installs an aggressive ingress policer on access ports requires the more specific qos policing shaping and trust verification control. The targeted action is: Differentiate supported ingress policing from egress shaping and confirm rate controls fit the actual traffic direction and SLA.
