Lower the encryption level.
Decrease the power setting.
Disable MAC address filtering.
Modify the Network Mode to Wireless-G.

176

176.Refer to the exhibit. Although they are directly connected, switch SWA is not exchanging VLAN information with switch SWC. What can be done to correct this problem?

Change the hostname of SWA to SWC.
Change the hostname of SWC to SWA.
Change the VTP version of SWA to version 1.
Change the VTP operating mode of SWA to transparent.

177

177.Refer to the exhibit. A technician is troubleshooting a trunk problem between switches SW1 and SW2. What should be done to remedy the problem?

“Negotiation of Trunking” on both switches should be turned off.
“Administrative Mode” on switch SW1 should be configured as dynamic auto.
Trunking Native Mode VLAN” on switch SW2 should be configured as VLAN 100.
“Operational Mode” on both switches should be configured as static access.

178.What allows WLAN clients to learn which networks and access points are available in an area?

SSID
probes
beacons
association

179. What technique is a security attack that depletes the pool of IP addresses available for legitimate hosts?

reconnaissance attack
DHCP spoofing
DHCP snooping
DHCP starvation

180

180.Refer to the exhibit. All edge ports are configured with the spanning-tree portfast command. Host1 is recently connected to port Fa0/1 on switch SW1. Which statement is true about the status of port Fa0/1?

The port will transition into blocking state.
The port will transition immediately into forwarding state.
The port will transition into blocking state and then immediately into forwarding state.
The port will transition into blocking state and immediately transition through the listening and learning states.

181.Which two devices can cause interference with the operation of a WLAN because they operate on similar frequencies? (Choose two.)

copier
AM radio
television
MP3 player
cordless phone
microwave oven

181. What is a result of improperly implementing a network with redundancy at Layer 2?

an increase of unicast and multicast errors at Layer 3
a decrease in the amount of broadcast traffic
end device malfunction because of broadcast storms
an increase in throughput at all points in the network

182. Which statement is correct about STP architecture?

Spanning Tree Protocol will guarantee a loop free Layer 2 topology.
Spanning Tree Protocol guarantees the shortest path to destination networks.
The switch with the highest priority will be assigned the lowest BID in the root election.
The first step in the spanning-tree election process is to determine the root port.
To select designated ports, the spanning-tree algorithm must determine the longest contiguous path from the root bridge.

  1. Claudio says:

    There are several wrong answers.
    Question number 42:
    Which three statements accurately describe VLAN types?
    A: 1,3,4;

    Question number 67:
    Refer to the exhibit. Host A is sending a frame to host C. How does switch SWA tag the frame?
    A: 4 – It does not tag the frame and sends it to host C;

    Question number 61:
    Which statement accurately describes routing between VLANs when the default gateway addresses of the VLANs are applied to physical interfaces.
    A: 1 or 4;

    Question number 54:
    A network administrator is implementing a Layer 2 solution for a legacy network that uses a combination of switches. Many of the older devices support only ISL trunking while others support both ISL and 802.1Q trunking. Which STP variant would be best suited for this network?
    A: 4 – PVST+

    Question:
    A network technician is investigating a problem on a switch that seems to have overflowing buffers and is dropping packets on many incoming ports. On examination the technician discovers that the problem exists because the destination port attaches to a busy server. What is the best way to address this problem?
    A: 4 – Change the switch to one that uses shared memory buffering.

    Zeuxid this is switching final answers for 2013?

  3. Jay says:

    Any ideas where I can find the images for the “Refer to the exhibit” questions?

  7. goshua says:

    Zeuxid i hop you fix it!:-)))) thks !!!!

  8. Goshua says:

    Zeuxid When you post new answers?

  9. Goshua says:

    Where did you updates? please hurry finish and post

  10. Goshua says:

    thanksss

  11. darkplayer says:

    The correct answer for Question 61:
    Which statement accurately describes routing between VLANs when the default gateway addresses of the VLANs are applied to physical interfaces.
    – there is no bandwidth contention on the router interface

  12. electro says:

    why this final exam is too long? how many question will have in the exam?

  13. darkplayer says:

    Correction:

    Zeuxid have you ccna4 final answers? i cann’t find:(((

  15. Goshua says:

    please create and post it!: )) I know you can do this

  16. Goshua says:

    zeuxid when you post ewan final answers?

  17. Goshua says:

    Zeuxid can you post answers of industrial sertifikat?

  18. asd says:

    Which three statements accurately describe VLAN types? (Choose three).

    A management VLAN is any VLAN that is configured to access management features of the switch.
    After the initial boot of an unconfigured switch, all ports are members of the default VLAN.

    AN 802.1Q trunk port, with a native VLAN assigned, supports both tagged and untagged traffic.

  19. veriuxus says:

    Thank you for these answers Zeuxid! I passed with 93.
