You manage network routes in an Azure subscription.
You have the following routes:
You observe that traffic destined to the IP address 192.168.1.0 is being sent to the IP address 10.10.5.5.
You need to ensure that the user-defined route takes precedence.
What should you do?
A. Add the user-defined route to the Border Gateway Protocol (BGP) table.
B. Delete and recreate the user-defined route.
C. Set the next hop of the user-defined route to the IP address 10.10.5.5.
D. Set the user-defined route subnet mask to the IP address 255.255.255.0.
Azure selects a route based on the destination IP address, using the longest prefix match algorithm. For example, a route table has two routes: One route specifies the 10.0.0.0/24 address prefix, while the other route specifies the 10.0.0.0/16 address prefix. Azure routes traffic destined for 10.0.0.5, to the next hop type specified in the route with the 10.0.0.0/24 address prefix, because 10.0.0.0/24 is a longer prefix than 10.0.0.0/16, even though 10.0.0.5 is within both address prefixes. Azure routes traffic destined to 10.0.1.5, to the next hop type specified in the route with the 10.0.0.0/16 address prefix, because 10.0.1.5 isn’t included in the 10.0.0.0/24 address prefix, therefore the route with the 10.0.0.0/16 address prefix is the longest prefix that matches.
Because 192.168.1.0 is currently being sent to 172.16.1.10.
Wait. I read that wrong. Good question.
Can someone give an explanation why C is the answer ?
