Cisco 300-710 Practice Test 44
Question 430
A firewall service owner escalates the following: Remote users see a translated address inconsistent with the firewall design because packet matching references original and translated tuples incorrectly. Which TWO complementary choices provide the most appropriate corrective action and its direct independent verification? Select TWO answers.
- Inspect intrusion rule identity, traffic payload sample, triggered variables and event distribution before and after tuning.
- Inspect NAT rule evaluation, original and translated addresses, routing and packet tracer output for the actual flow.
- Assume NAT rules are unordered and any matching translation may be selected arbitrarily without affecting policy.
- Configure appropriate NAT and policy order with correct ingress and egress mapping and test before deploying.
- Place sufficiently specific access-control rules in intended evaluation order and set a documented default action.
Explanation
Correct Answers
B:Direct independent How to verify: Inspect NAT rule evaluation, original and translated addresses, routing and packet tracer output for the actual flow.
D:Appropriate implementation: Configure appropriate NAT and policy order with correct ingress and egress mapping and test before deploying. Case details: Remote users see a translated address inconsistent with the firewall design because packet matching references original and translated tuples incorrectly. Governing behavior: Address translation follows platform-specific rule sections and matching rules, and access-control analysis may reference different packet representations.
Incorrect Answers
A:This alternative describes a different control, Custom intrusion rules and rule-set tuning, rather than this scenario’s NAT rule ordering and address translation flow: Inspect intrusion rule identity, traffic payload sample, triggered variables and event distribution before and after tuning.
C:Unsafe or unsupported shortcut for this firewall scenario: Assume NAT rules are unordered and any matching translation may be selected arbitrarily without affecting policy.
E:This alternative describes a different control, Access control policy ordering and default behavior, rather than this scenario’s NAT rule ordering and address translation flow: Place sufficiently specific access-control rules in intended evaluation order and set a documented default action.
Question 431
An approved maintenance window surfaces this issue: A critical voice path is delayed after a firewall change because priority marking is rewritten and no supported QoS rule matches it. Which security configuration or operational step BEST addresses the requirement? Select ONE best answer.
- Align supported routing selection and QoS policies with documented egress, markings and bandwidth behavior.
- Assume a firewall QoS policy can increase physical link capacity or fix any routing error by itself.
- Define and review reusable network or host objects with scoped references and test impacted policies before edits.
