Question 151

Refer to the exhibit. Which action resolves intermittent connectivity observed with the SNMP trap rackets?

    Correct Answer: B

    The class map 'mgmt' is configured with a police rate, and the exhibit shows that a significant number of packets (353 out of 361) have exceeded the configured CIR (Committed Information Rate). These packets are being dropped as a result. To prevent the drops and resolve the intermittent connectivity issue with the SNMP trap packets, increasing the CIR will allocate more bandwidth for the class, allowing more packets to conform to the policy and be transmitted instead of dropped.

The given answer is correct

willleeOption: C

anybody? i think its C

spapi0390

it could be but as far as exceeded actions its dropping then the given answer is correct

Alnet

No. SNMP Trap is on port 162. Port 161 is just for SNMP requests (get, inform...), but not SNMP Traps.

MalasxdOption: B

B is right. The firs line says "Service-policy OUTPUT", so the traffic is originated by the router. We also can see the class mgmt has exceeded matches and it is dropping packets. A) does not make sense. the class already dropping packet, if you decrease the CIR it will get even worse. B) is right. The class is dropping the packets because they exceeded the bandwidth. If you increase to the correct bandwidth it will work. C) SNMTP traps works in port 162. D) does not make sense

GreatDaneOption: B

As the exhibit shows, among all matches by ACL 120 (361 packets), 353 exceeded the CIR of class map mgmt, while only 8 packets conformed to it. Here, the first thing to do is to give more bandwidth to class map mgmt. A. Decrease the committed burst size of the mgmt class map. Wrong answer. B. Increase the CIR of the mgmt class map. Correct answer. C. Add one new entry in the ACL 120 to permit the UDP port 161. Wrong answer. D. Add a new class map to match TCP traffic. Wrong answer.

The given answer is correct

SeMo0o0o0Option: B

B is correct

HuntkeyOption: D

Control-plane policing matches the inbound traffic. SNMPTRAP are outbound traffic. the policy doesn't affect it at all. The match in the ACL would mean other devices sending traps to this local router or something. SNMPTRAP is connection less and stateless. There is no such thing for intermittent connectivity for SNMPTRAP traffic. My understanding is that some TCP connection got disconnected constantly because of the class-map and the router is sending out SNMPTRAP to notify people about it. Therefore, I would go with D

Huntkey

Never mind... Apparently the policy-map can also be applied for the output direction... B is correct

Vince64Option: B

Connectivity is intermittent so C and D may not be the correct answer
