Exhibit
Client IP address: 192.168.50.23/24 Ping to 192.168.50.1 succeeds Ping to 8.8.8.8 fails DHCP pool intended for VLAN 50 users
Exhibit: A client receives an IP address but cannot reach remote networks. Which DHCP option is most likely missing or incorrect?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
DNS server option
DNS affects name resolution, not basic routed connectivity.
B
Distractor review
Lease time option
Lease time controls duration, not path to remote networks.
C
Best answer
Default gateway option
Without the correct gateway, off-subnet traffic fails.
D
Distractor review
TFTP server option
TFTP is irrelevant for a normal client PC.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.

FAQ
Questions learners often ask
What does this 200-301 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Default gateway option — The host can communicate only on the local subnet when the default gateway is wrong or missing. In DHCP, that gateway is delivered with option 3, the router option.
What should I do if I get this 200-301 question wrong?
Then try more questions from the same exam bank and focus on understanding why the wrong options are tempting.
