Refer to the exhibit. The output shows a DHCP exchange between a client (MAC 00:1a:2b:3c:4d:5e) and a server (192.168.1.1). The client is not obtaining an IP address. What is the most likely reason?

Exhibit

Refer to the exhibit.

Output of `tcpdump -i eth0 port 67 or port 68`:

```
13:10:05.123456 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 00:1a:2b:3c:4d:5e, length 300
13:10:05.123789 IP 192.168.1.1.67 > 255.255.255.255.68: BOOTP/DHCP, Reply, length 300

Question 13hardmultiple choice
Read the full DHCP explanation →

A company has a Linux client running Ubuntu 20.04 that is used by multiple developers. The client has two network interfaces: eth0 (connected to the corporate network with DHCP) and eth1 (connected to a test lab with static IP 192.168.100.10/24). The client needs to access both the internet (via eth0) and the lab network (192.168.100.0/24). The default gateway is 10.0.0.1 on eth0. The lab network has a server at 192.168.100.50 that provides DHCP for the lab devices, but the client's eth1 is statically configured. Recently, the client cannot reach the lab server at 192.168.100.50. The administrator checks the routing table and sees:

Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface

0.0.0.0         10.0.0.1        0.0.0.0         UG    100    0        0 eth0
10.0.0.0        0.0.0.0         255.255.255.0   U     100    0        0 eth0
192.168.100.0   0.0.0.0         255.255.255.0   U     100    0        0 eth1

The administrator can ping 192.168.100.50 from the client. However, the lab server cannot ping the client. What is the most likely cause?

Question 14mediummultiple choice

A system administrator notices that a Linux client is unable to resolve hostnames after connecting to a new network. The client uses DHCP and the /etc/resolv.conf file contains only the loopback address 127.0.0.1. Which of the following is the most likely cause?

A Linux workstation must be configured to automatically mount an NFS share from server nfs.example.com:/exports/data at boot time. The share should be mounted with noexec and nosuid options. Which line should be added to /etc/fstab?

Which TWO commands can be used to display the current IP address and netmask of network interfaces on a Linux system?

Question 17mediummultiple choice
Read the full DHCP explanation →

You are troubleshooting a Linux client that is unable to connect to the internet. The client is configured to use DHCP on interface eth0. The output of 'ip addr show eth0' shows that the interface has an IP address 192.168.1.100/24, but there is no default gateway. The output of 'ip route show' shows only the local subnet route. The DHCP server is at 192.168.1.1 and is functioning correctly. You have verified that the DHCP client (dhclient) is running, and the lease file /var/lib/dhclient/dhclient-eth0.leases exists and contains option routers 192.168.1.1. Which of the following commands should you run to resolve the issue?

Question 20easymultiple choice
Read the full DHCP explanation →

You are a system administrator at a small company. The network uses DHCP to assign IP addresses to clients. Recently, some users reported intermittent network connectivity issues. Upon investigation, you notice that the DHCP server is running on a Linux server with the ISC DHCP daemon. The server log shows many 'DHCPREQUEST' messages from a particular MAC address with frequent changes in requested IP addresses. Users with that MAC address are experiencing IP address conflicts and connectivity drops. What is the most likely cause and the best corrective action?

How should I use these practice questions?
Select your answer before revealing the explanation. Then read why each option is right or wrong — this active recall approach builds retention far faster than re-reading notes.
Can I practise just Network Client Management questions in a focused session?
Yes — the session launcher on this page draws every question from the Network Client Management domain. Use a 10-question session first to gauge your baseline, then move to 20 or 30 once the weak spots are clear.
Where can I practise other LPIC-2 topics?
Use the topic links above to move to related areas, or go back to the LPIC-2 question bank to see all topics.
Are these real exam questions or dumps?
These are original practice questions written to test the same concepts the LPIC-2 exam covers. They are not copied from any real exam or dump site.
