A virtual machine has the following configuration:

* IPv4 address: 169.254.10.10

* Subnet mask: 255.255.0.0

The virtual machine can reach colocated systems but cannot reach external addresses on the internet. Which of the following is most likely the root cause?

A.
The subnet mask is incorrect.
Answers
A.
The subnet mask is incorrect.
B.
The DHCP server is offline.
Answers

C.
The IP address is an RFC1918 private address.
Answers
C.
The IP address is an RFC1918 private address.
D.
The DNS server is unreachable.
Answers
D.
The DNS server is unreachable.
Suggested answer: B

Explanation:

The IP address 169.254.10.10 is an APIPA (Automatic Private IP Addressing) address, which is assigned by the operating system when a DHCP server is not available or reachable. APIPA addresses are in the range of 169.254.0.0/16, and they allow the device to communicate with other devices on the same local network, but not with external networks or the internet. Therefore, the most likely root cause of the virtual machine's connectivity issue is that the DHCP server is offline or malfunctioning, and the virtual machine cannot obtain a valid IP address from it.
