A new floor has been added to the enterprise campus network, providing client access for desktop PCs, laptops, and IP phones for employees and guests. During verification, a few desktop PCs have limited corporate access but not Internet access. Most other desktop PCs, all laptops, and IP phones are working correctly. Additional information indicates that the desktop PCs are obtaining IP host addresses from the DHCP server, which is intended for only the IP phones.
Where should troubleshooting about this connectivity issue be focused?
A.
client network configuration
B.
VLAN mapping
C.
DHCP server and options
D.
DNS
E.
routing protocols
F.
first-hop redundancy protocol
Explanation:
The private vlan mapping maps the secondary VLANs to the Layer 3 VLAN interface of a primary VLAN to allow Layer 3 switching of private-VLAN ingress traffic.
Would you be able to elaborate, please? Why it couldn’t be option A – client network configuration?
Thanks.

ok, I see. On power up station starts sending “dchp discover” and it’s switched to the wrong VLAN/subnet.
We can’t configure dhcp setting on client machine – so, it’s not option A.
Option C is not correct because we are not even reaching the right DHCP server.
D,F nothing to do with the issue and E is not right because DHCP should be on the same segment or DHCP relay should be configured, which is not relates to routing protocols.
Am I making right conclusions?
