1. Refer to the exhibit. Which two outcomes occur from the configuration shown? (Choose two.)
The broadcasts will be forwarded to 10.1.1.1.
The router will use DLCI 22 to forward data to 10.1.1.1.
DLCI 22 will replace the MAC address in the ARP table for entry 10.1.1.1
Inverse-ARP will now add an entry for 10.1.1.1 into the Frame Relay map table using DLCI 22.
Frames sent by 10.1.1.1 arriving on interface serial 0/0/0 of RT_1 will have a data link layer address of 22.
2. Refer to the exhibit. What can be determined from the output?
Serial 0/0/0 has been configured with an DLCI of 201.
Serial 0/0/0 has the feature frame-relay inverse-arp enabled.
Serial 0/0/0 has been configured with an IP address of 172.16.4.3.
Serial 0/0/0 has been configured with the command frame-relay map ip 172.16.4.3 201 broadcast.
3. Refer to the exhibit. What effect does the point-to-point configuration on subinterface S0/0.110 have on the operation of the router?
It helps to conserve IP addresses.
It establishes multiple PVC connections to multiple physical interfaces.
It eliminates split horizon issues without increasing the likelihood of routing loops.
It requires the configuration of the encapsulation command on the subinterface.
1. Which parameter is used to uniquely identify one wireless network from another?
2. Refer to the exhibit. How does SW1 manage traffic coming from Host A?
SW1 drops the traffic because it is untagged.
SW1 leaves the traffic untagged and forwards it over the trunk.
SW1 tags the traffic with the lowest VLAN ID value and forwards it over the trunk link.
SW1 encapsulates the traffic with 802.1Q encapsulation and forwards it over the trunk link.
3. What is a possible impact of setting too short an aging time in the MAC address table of a switch?
overly large address table
unnecessary flooding of packets
excessive timeouts of static addresses
impaired ability to dynamically learn new addresses
1. Wireless users on a network complain about poor performance within a small area of a room. Moving away from this area in any direction improves performance dramatically. What is the first step in designing a solution to this problem?
This might be RF channel overlap, so the technician should verify the channels in use on each wireless access point and change to non-overlapping channels.
The RF power settings might be set too low on the wireless access points servicing the room. Increase the RF output power on all wireless access points.
Install a new wireless access point in this center area to provide coverage.
Verify that the wireless access points have sufficient in-line power and connectivity to the wired network.
2. Which network design process identifies where to place access points?
network protocol analysis
3. What will a wireless client transmit to discover the available WLAN networks?
1. Refer to the exhibit. All devices are configured as shown in the exhibit. PC2 can successfully ping the F0/0 interface on R1. PC2 cannot ping PC1. What might be the reason for this failure?
R1 interface F0/1 has not been configured for subinterface operation.
S1 interface F0/6 needs to be configured for operation in VLAN10.
S1 interface F0/8 is in the wrong VLAN.
S1 port F0/6 is not in VLAN10.
2. Refer to the exhibit. Switch1 is correctly configured for the VLANs that are displayed in the graphic. The configuration that is shown was applied to RTA to allow for interVLAN connectivity between hosts attached to Switch1. After testing the network, the administrator logged the following report:
Hosts within each VLAN can communicate with each other.
Hosts in VLAN5 and VLAN33 are able to communicate with each other.
Hosts connected to Fa0/1 through Fa0/5 do not have connectivity to host in other VLANs.
Why are hosts connected to Fa0/1 through Fa0/5 unable to communicate with hosts in different VLANs?
The router interface is shut down.
The VLAN IDs do not match the subinterface numbers.
All of the subinterface addresses on the router are in the same subnet.
The router was not configured to forward traffic for VLAN2.
The physical interface, FastEthernet0/0, was not configured with an IP address.
3. Refer to the exhibit. Which three statements describe the network design shown in the exhibit? (Choose three.)
This design will not scale easily.
The router merges the VLANs into a single broadcast domain.
This design uses more switch and router ports than are necessary.
This design exceeds the maximum number of VLANs that can be attached to a switch.
This design requires the use of the ISL or 802.1q protocol on the links between the switch and the router.
If the physical interfaces between the switch and router are operational, the devices on the different VLANs can communicate through the router.
1. In which two ways is the information that is contained in BPDUs used by switches? (Choose two.)
to negotiate a trunk between switches
to set the duplex mode of a redundant link
to identify the shortest path to the root bridge
to prevent loops by sharing bridging tables between connected switches
to determine which ports will forward frames as part of the spanning tree
2. In which STP state does a port record MAC addresses but not forward user data?
3. Refer to the exhibit. The spanning-tree port priority of each interface is at the default setting. The network administrator enters the spanning-tree vlan 1 root primary command on S4. What is the effect of the command?
Spanning tree blocks Gi0/1 on S3.
Gi0/2 on S3 transitions to a root port.
Port priority makes Gi0/2 on S1 a root port.
S4 is already the root bridge, so there are no port changes.
