4-4IP ServicesEasy

Notifications from a branch device cross a lossy WAN and some never reach the monitoring platform. Which notification type lets the sender learn that one arrived?

A get request repeated by the platformPolling asks for values the manager already knows to ask about, which misses events between polls.

A trap sent to a second receiver as wellA second unconfirmed copy improves the odds and still tells the sender nothing.

A response returned for each notificationUnconfirmed notifications draw no reply at all, which is the gap in this scenario.

An inform request, which is acknowledgedCorrect · your answerCorrect. The confirmed notification is answered, so a loss can be detected and retried.

Concept

A notification carried over a datagram service has no delivery guarantee, and a sender with no acknowledgement cannot tell a delivered event from a lost one. Adding a reply to the exchange turns a fire and forget message into one the sender can retry.

Why D

Now you: objective 4.4 questions

No account needed. The explanation opens when you answer.

Sample question 1 of 3

4-4IP ServicesModerate

A monitoring platform gets no answer to a poll sent to a busy switch. Which component decides whether that poll is sent again?

Sample question 2 of 3

4-4IP ServicesHard

An engineer walks a large interface table and switches to bulk retrieval with a very high repetition count. Responses now arrive fragmented and some collections fail. What causes the failures?

Sample question 3 of 3

4-4IP ServicesEasy

A switch is configured to send an alert to a monitoring platform when a fan fails, without being asked for it. Which application role is the switch running?
