Which controller shown in the exhibit is elected as the cluster leader?
In a controller cluster, the election of the cluster leader typically follows a specific order of criteria: Priority first, then the model value (platform), and finally the MAC address if the previous criteria are equal. In this exhibit, all controllers appear to have equal priority and thus, the next criteria are the model value and the MAC address. Here, Controllers A and B are 7240 models, while Controllers C and D are 7030 models. Since model 7240 is considered higher than model 7030, we then compare the MAC addresses of the controllers. The MAC addresses of Controllers A and B are 'a1' and 'a2' respectively. However, if we convert the MAC addresses to a fully numerical form (hexadecimal to decimal), the highest would be the one ending with 'bb' (Controller D). Therefore, Controller D is elected as the cluster leader based on the highest MAC address.
Yes this is a typo in the question all priorities being equal then it goes by model then mac address. So the highest MAC on the highest model is B.
The correct is B
Controller B Highest Model, Highest MAC
Answer is B: Election order is: Priority > Platform value(model) > MAC
The highest MAC address is "bb", so the answer is D. Convert a2 to decimal=162, convert bb=187.
