QUESTION 46:
A PassGuide network is displayed below:
640-816
www.actualtest.org – The Power of Knowing
Host PassGuide B in the diagram is experiencing connectivity problems. Further
Testing reveals that it cannot ping the default gateway. Based on the information
shown in the exhibit, what is the problem?
A. The IP address of PassGuide B is on a different subnet than the default gateway.
B. The Fa0/1 interface on the switch is administratively shutdown.
C. The switch is connected to the wrong interface on the PassGuide 1 router.
D. The FastEthernet interface on the PassGuide router is not configured for trunking.
E. The Fastethernet 0/0.2 interface on the PassGuide 1 router is configured for the wrong
VLAN.
F. The FastEthernet interface of the PassGuide 1 router is configured with the wrong
Ethernet encapsulation.
Answer: E
Explanation:
Based on the output shown above, the Fa 0/0.2 interface should be in VLAN 32, which is
the same VLAN that other devices in the 192.168.2.X/24 subnet belong to. Interface
FA0/0.1 should be configured for VLAN 22, while FA0/0/2 should be configured for
VLAN 32.
QUESTION 47:
A PassGuide switch is connected as shown below:
640-816
www.actualtest.org – The Power of Knowing
In the network above Host 1 cannot ping Host 2. What needs to be configured to
allow host 1 and host 2 to communicate?
A. The switch needs to be configured with an IP address on the correct subnet.
B. The default gateway of the hosts should be configured to 192.168.1.2.
C. Spanning Tree Protocol needs to be configured on the switch.
D. A router needs to be configured to route between the VLANs.
E. VTP needs to be configured on the switch to create a trunk between the VLANs.
Answer: D
Explanation:
By default only members of the same VLAN can communicate with each other. For
inter-VLAN communication we require a router to route between the different VLANs.
Alternatively, if Host1 and Host2 were in the same subnet and the same VLAN, then they
would also be able to communicate.
QUESTION 48:
The PassGuide network is shown below:
640-816
www.actualtest.org – The Power of Knowing
The network administrator normally establishes a Telnet session with the switch
from host
A. However, host A is unavailable. The administrator’s attempt to telnet
to the switch from host B fails, but pings to the other two hosts are successful. What
is most likely the issue?
A. Host B and the switch need to be in the same subnet.
B. The switch interface connected to the router is down.
C. Host B needs to be assigned an IP address in VLAN 1.
D. The switch needs an appropriate default gateway assigned.
E. The switch interfaces need the appropriate IP addresses assigned.
Answer: D
Explanation:
This scenario requires inter-VLAN routing, which requires a layer three device. Based on
the information above, a trunk has indeed been set up to route traffic between VLAN’s so
the only logical explanation why a host in VLAN 32 can not reach a host in VLAN1
(which is where the IP address of the switch is) would be because no default gateway has
been specified in the switch.
Incorrect Answers:
A, C: This is not a requirement, as a number of VLAN’s can be configured within a
switch, while the management IP address can reside in a different VLAN on a different
subnet.
B: Based on the output above, the trunk link (fa 0/3) is indeed up and active.
E: Since switches operate at layer 2, each individual VLAN does not need its own IP
address.
QUESTION 49:
640-816
www.actualtest.org – The Power of Knowing
A portion of the PassGuide network is shown in the following exhibit:
Based on this diagram, which of the following is true?
A. Switch CK2 is the root bridge.
B. Spanning Tree is not running.
C. Host D and Server 1 are in the same network.
D. No collisions can occur in traffic between Host B and Host C.
E. If Fa0/0 is down on Router 1, Host A cannot access Server 1.
F. If Fa0/1 is down on Switch 3, Host C cannot access Server 2.
G. None of the above
Answer: E
Explanation:
A VLAN is a group of hosts with a common set of requirements that communicate as if
they were attached to the same wire, regardless of their physical location. A VLAN has
the same attributes as a physical LAN, but it allows for end stations to be grouped
together even if they are not located on the same LAN segment.
The above diagram is configured with inter-VLAN communication so the router has a
great role to make communication between different VLAN. When router’s port
configured with trunk goes down all host can’t communicate with other host in different
VLAN as it is the router that directs traffic between the separate VLANs.
QUESTION 50:
The corporate LAN shown in the PassGuide network uses IP network 172.28.4.0/22
for all departments. All workstations use 172.28.4.1 as a default gateway address.

In this network, administrators have recently become concerned that excessive
broadcasts are slowing network performance. Which change is most likely to reduce
broadcast traffic on the corporate LAN?
A. Configure an access control list on the router to prevent broadcast forwarding.
B. Configure each NIC and switch port to operate at full duplex.
C. Change the router-to-switch connection from Fast Ethernet to Gigabit Ethernet.
D. Implement VLANs after creating IP subnets for each department.
E. Increase the number of switches in the network closet of each department.
