Exam AZ-800 topic 1 question 33 discussion

In the Attribute Editor tab, double click on Options. If the Value(s) box shows <not set>, type 1. There is one caveat however. Change notification will fail with manual connection objects. If your connection objects are not created by the KCC the change notification setting is meaningless. If it's a manual connection object, it will NOT inherit the Options bit from the Site Link. Enjoy your 15 minute replication latency.

To change the delay between the change to Active Directory and the first replication partner notification, open the Configuration partition in the ADSIEdit tool and go to CN=Partitions,CN=Configuration,DC=<Forest Root Domain>. In the container, right-click the crossRef object of the directory partition you want to modify the replication settings. msDS-Replication-Notify-First-DSA-Delay - The attribute controls the delay between changes to the Directory Services (DS) and the notification of the first replica partner for a naming context (NC). The interval is 15 seconds if the attribute isn't set. msDS-Replication-Notify-Subsequent-DSA-Delay - The attribute specifies the delay between notifications of each subsequent replica partner for an NC. The interval is three seconds if the attribute isn't set.

Read the question carefully, if you see a similar one, don't just think it's the same answer. There is a difference between convergence and latency This question refers to latency, which is about the delay in a replication cycle for individual changes and you minimize it by configuring the options attribute. The convergence question which is very similiar sounding is not the same thing. Convergence time is about how long it takes for all the DC's to be updated and you can minimize that by adjusting the replication schedule.

The correct answer to this question is D. For each site link, modify the replication schedule. In a multi-site Active Directory forest, replication between sites is controlled by site links, and these links have a replication schedule that determines how often changes are replicated between domain drivers located in different sites.

change notification may be enabled between site links that can span geographic locations. This will make Active Directory replication instantaneous between the separate sites as if the replication partners were in the same site.

To minimize the latency you need to modify attributes.

D. For each site link, modify the replication schedule.

This exact same question is in the MeasureUp practice test test, and the answer they're looking for is D. Not saying it's even technically the "most" correct, but on paper, the answer they're expecting is "D" for this question.

C is the correct answer. Setting the option attribute will notify the domain controllers in domain to sync with every change.

Sorry, I will contradict my solution below, The answer is C.

I think the answer is D, you can adjust the replication schedule to manage latency, but C will only enforce replication.
