Question 10

Acme Provisioning, Inc., a local IT integration provider, has just completed redesigning its campus LAN with VLAN segmentation. You, as the company's network administrator, have been tasked to connect 10 Windows XP Professional workstations to the access-layer switches (Catalyst 2900XL switches).

You verify that correct IP address, subnet mask, default gateway, and DNS servers have been configured on all PCs. You have also checked that correct Category 5 cabling are used for the connection. However, some workstations are experiencing problems connecting to other workstations on the same switch.

Which of the following is most likely cause of the problem?

a.        The access-layer switch does not propagate the host routing entries to the core layer switches.

b.       The switch ports on which the workstations are connected to are configured with incorrect VLAN.

c.       The workstations have been configured with invalid MAC addresses.

d.       Spanning-Tree Protocol (STP) has been disabled on those switch ports.

e.       The router that performs intra-VLAN routing does not have route entries for the workstations.
