Refer to the exhibit. What two facts can be determined from the WLAN diagram? (choose two)
A. Access points in each cell must be configured to use channel 1.
B. The network diagrm represents an extended servics (ESS).
C. The area of overlap of the two cells represents a basic servics set (BSS).
D. The area of overlap must be less than 10% of the area to ensure connectivity.
E. The two APs should be configured to operate on different channels.

Correct B, E

An administrator is configuring a router that will act as the hub in a frame Realy hub-and-spoke topology. What is the advantage of using point-to-point subinterfaces instead of a multipoint interface on this router?
A. It avoids split-horizon issues whith distance vector routing protocols.
B. Only one IP network address nedds to be used to communicate with all the spoke device.
C. Only a single physical interface is needed with point-to-point subinterfaces, whereas a multipoint interface logically combines multiple physical interface.
D. Point-to-point subinterfacec offer greater  security compared to a multipoint interface configuration.

Correct A
Explaination :
Split horizon indicates that in distance vector routing protocol, once you learn of a route through an interface, advertise it as unreachable back through that same interface in order to avoid routing loops. In a NBMA network such as FR, for the hub-spoke topology, on the point-to-multipoint interface at the hub end, routing information from a PVC is virtually needed to advertise other PVCs, instead, the characteristics of split horizon will not allow for such advertise, which result in spill horizon issues. Only refer to IGRP, on the physical interface of FR, split horizon is disabled default. On the point-to-point sub-interface adn point-to-multipoint sub interface of FR, split horizon is enabled. So, split horizon usually happens to point-to multipoint sub-interface, there are several solutions to issue this problem : Using no ip split-horizon command to disable split horizon on point-to-multipoint sub-interface, but this method will cause routing loops that can be resolved by distribute-list through transforming point-to-multipoint sub-interface into point-to-point sub-interface, meanwhile, you should notice that each point-to-point sub-interface should use network address respectively.

Refer to the exhibit. The two connected ports are not running orange or green. What would be the most effective steps to troubleshoot this physical layer problem? ( choose three)


A. Ensure that the Ethernet encapsulations match on the interconnected Router and Switch ports.
B. Ensure that cables A and B are staight-through cables.
C. Reset all cables.
D. Ensure the Switch has power.

Correct B, C, D

A single 802.11g access point has been configured and installed in the center of a square shape office. A few wireless users are experiencing slow performance and drops while most users are operating at peak efficiency. From the list below, what are there likely causes of this problem? ( choose three)
A. mismatched TKIP encryption
B. null SSID
C. cordless phones
D. mismatched SSID
E. metal file cabinets
F. antenna type or direction

Correct C,E,F
Explaination :
C : if you have cordless phones or other wireless electronics in your home or office, your computer might not be able to "hear" you router over the noise from the other wireless devices. To quite the noise, avoid wireless electronics that use the 2,8GHz frequency. Instead, look for coordless phones that use the 5,8GHz or 900MHz frequencies.
E : The antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your office, and much of your router's power will be wasted.

You are network administrator, in order to improve the security of switching network, refer to the following options. Which two methods are examples of implementing Layer 2 security on a Cisco switch? ( Choose two)
A. disable trunk negotiation on the switch.
B. use only protected Telnet sessions to connect to the Cisco device.
C. configure a switch port host where appropriate.
D. enable HTTP access to the switch for security troubleshooting.


Correct A, C
Explaination :
With the popularity and constantly deepening of network applications, the users? Requirements for 2 Layer 2 switches are not only limited to data forwarding performance and quality of service (QoS), but also philosophy of network security which is becoming an increasingly an important consideration of networking products. How to filter user communications and ensure safe and effective data transmission? How to block the illegal users and make network work safely? How to execute secure network management and detect illegal users, illegal activities and security performance of remote network management information in time? The following methods can accomplish network Layer 2 security by working on switches.

The purpose for setting ACLs on a router are controlling vty access into a router and filtering traffic as it passed through a router.

Access Control List (ACL) can be used to affect traffic transmited from one port to another. It acquired its name due to having filtering capability when traffic flows in and out of interface and it also can be used for other purposes, such as :
A. Place restrictions on accessing router Telnet (VTY).
B. Filter routing information.
C. Distinguish precedence of WAN traffic by queuing technology. 
D. Tringger calls through the Dial-on-demand routing (DDR).
E. Change administrative distance of routing
