Two Reasons to Implement DHCP in a Network

200-301 By islever Editorial Last updated

Explain the role of DHCP and DNS within the network

Short answer

BC DHCP controls how long an address is leased (B) and reduces the administrative effort of managing client IP ranges (C).

Question

What are two reasons to implement DHCP in a network? (Choose two.)
  1. manually control and configure IP addresses on network devices
  2. control the length of time an IP address is used by a network device Correct Answer
  3. reduce administration time in managing IP address ranges for clients Correct Answer
  4. dynamic control over the best path to reach an IP address
  5. access a website by name instead of by IP address

Key Takeaways

The two valid DHCP benefits are operational: controlling lease duration and cutting administrative overhead. Manual control, routing, and name resolution are not DHCP's purpose.

DHCP automates address assignment, so administrators avoid manual IP configuration (A is the opposite) and save time managing ranges (C). Lease time (B) is a DHCP-controlled parameter. Routing path selection (D) is a router function, and name-to-IP resolution (E) is DNS.

Common mistake: Picking A (DHCP removes manual config, it does not add it), D (routing/best path is not DHCP), or E (name resolution is DNS).

Expert Analysis

Why the Answer Is Correct

B and C are correct. B: DHCP sets the lease time a client may use an address. C: DHCP removes per-client manual IP administration, reducing operational effort.

Why the Other Options Are Wrong

A is wrong: DHCP is automatic, not manual, IP control. D is wrong: selecting the best path is routing, not DHCP. E is wrong: resolving a name to an IP is DNS, not DHCP.

Community Comment Notes

The vote is BC (100). The discussion is mostly exam-tips chatter, but the technical consensus is that lease control and reduced administration are the two DHCP benefits.

    I know a lot of people said this already but this dump is legit. I had 90 questions including 3 labs. My suggestion is review all 1300 questions and focus on the ones you got wrong. For me I missed 328 questions out 1349. I study those and cram 24 hrs before my test. Once you study everything and learn the concept you will do just fine. The labs I got were not exactly like the ones on here but they were very similar. I skipped one lab, completed one and partially completed the last one. I was running out of time but I finished the exam with 10 minutes left. Most importantly I passed :). Good luck everyone! On to the next one!!!

    I would like to share more details for those who never have cisco exam before.(I take the exam on 15/6/2024) 1. You will be requested to take all your personal belonging into a locker. 2.A pen and paper will be provided to you to take note or calculating the subnet. 3.The time is enough if you finish all questions on this website as the questions are allmost the same with the question on this website. Please read the questions carefully. Do not miss the point you should have got. 4. Please read the discussion of each question on this webpage if you are not want to pass the exam only. All discussions are very useful to have a deeper understanding of networking even though it may not cover in the exam. It can also help you to eliminate some options if you are not sure which one is the correct answer.

    I went through all the 1349 questions and this dump is legit and I took it before the implementation of new syllabus of CCNA v1.1. I had 88 questions including 3 lab questions. Two lab questions were quite similar and only one lab question on OSPF was quite different with required to perform only two main tasks. Each of the task was asking to two more sub-tasks. Overall, study and understand the answer behind each of the question.
