The access link needs to be configured in multiple VLANs.
B -
The link between the switches is configured in the wrong VLAN.
C -
The link between the switches needs to be configured as a trunk.
D -
VTP is not configured to carry VLAN information between the switches.
4-
Refer to the exhibit. Which one statements is true of the interfaces on Switch1?
Exhibit:

Multiple devices are connected directly to FastEthernet0/1.
C -
FastEthernet0/1 is configured as a trunk link.
D -
FastEthernet0/1 is connected to a host with multiple network interface cards.
5-
A receiving host computes the checksum on a frame and determines that the frame is damaged.
The frame is then discarded. At which OSI layer did this happen?
A -
transport
B -
data link
C -
session
D -
physical

Two routers named Atlanta and Brevard are connected by their serial interfaces as shown in the
exhibit, but there is no data connectivity between them. The Atlanta router is known to have a
correct configuration. Given the partial configurations shown in the exhibit, what is the problem on
the Brevard router that is causing the lack of connectivity?
A -
incompatible IP addresses
B -
insufficient bandwidth
C -
incorrect subnet mask
D -
incompatible encapsulation

Refer to the exhibit.
C-router is to be used as a "router-on-a-stick" to route between the VLANs. All the interfaces have been properly configured and IP routing is operational. The hosts in the VLANs have been
configured with the appropriate default gateway. What can be said about this configuration?
A -
These commands need to be added to the configuration: C-router(config)# router eigrp 123 C-router(config-router)# network 172.19.0.0
B -
No further routing configuration is required.
C -
These commands need to be added to the configuration: C-router(config)# router ospf 1C-router(config-router)# network 172.19.0.0 0.0.3.255 area 0
D -
These commands need to be added to the configuration: C-router(config)# router ripC-router(config-router)# network 172.19.0.0

A -
TFTP
B -
SNMP
C -
DNS
D -
All of them
9-
Refer to the Exhibit.

as indicated by the command out put shown?
A -
One interface has a problem.
B -
Two interfaces have problems.
C -
The interfaces are functioning correctly.
D -
The operational status of the interfaces cannot be determined from the output shown.

Refer to the exhibit.
Based on the exhibited routing table, how will packets from a host within the 192.168.10.192/26
LAN be forwarded to 192.168.10.1?
A -
The router will forward packets from R3 to R1.
B -
The router will forward packets from R3 to R2 to R1 AND from R3 to R1.
C -
The router will forward packets from R3 to R1 to R2.
D -
The router will forward packets from R3 to R2 to R1.
