B. The shortest route is always selected.
C. The most specific route is selected over the default gateway.
D. A dynamic route is selected over a directly attached network.
Answer: C
Explanation:
Router always looks for the most closely matched route for forwarding the packet. For example if
there are two routes in your router and you have to send a packet to a host with an ip 10.10.10.10 then it will forward packet to 192.168.1.10 rather than 192.168.1.1:
Network Destination Netmask Gateway
0.0.0.0 0.0.0.0 192.168.1.1

QUESTION 242
Lab Simulation
Wireless network users recently began experiencing speed and performance issues after access point 2 (AP2) was replaced due to faulty hardware.
The original network was installed according to a consultant’s specifications and has always worked without a problem.
You, a network technician, have been tasked with evaluating the situation and resolving the issues to improve both performance and connectivity.
Refer to the following diagram and perform any NECESSARY changes to the wireless and wired infrastructure by adjusting devices.
Note: Adjust the LEAST number of devices needed to fix the issue, all blue icons in the image are clickable.
When you feel the simulation is complete please select the Done button.
Answer:
– Change the speed and duplex settings on AP2 only to 100 and full.
– Change the mode to G on AP2
– Change the channel to 6 on AP2
Explanation:
Since we know that the network was running perfectly before replacing AP2 we should start by looking at this new device that was used to replace the old one. Here we see that the other AP’s have hard coded the speed and duplex settings to 100/full, while AP2 is set to auto/auto.
Also, the other AP’s have been configured to use 802.11G, while AP2 is using 802.11B.
Finally the channel that AP2 is using overlaps with AP1 which can cause problems.
Channels 1, 6, and 11 are spaced far enough apart that they don’t overlap.
On a non-MIMO setup (i.e. 802.11 a, b, or g) you should always try to use channel 1, 6, or 11. Since AP1 is using 1, and AP3 is using 11, AP2 should be using 6.
QUESTION 243
A user’s laptop is unable to keep a stable network connection. Which of the following measures would MOST likely need to be configured?
A. SSID name
B. WAP encryption strength
C. WAP radio power
D. Channel overlay
Answer: C
Explanation:
WAP radio power is the signal strength through which you can specify the range from which you can stay connected to the network and access internet. Here, when the user is not able to maintain a stable connection then it is a problem with the signal strength for sure so you can try to increase the signal strength by increasing the radio power.
QUESTION 244
The security administrator needs to restrict specific devices from connecting to certain WAPs. Which of the following security measures would BEST fulfill this need?
A. WAP placement
B. MAC address filtering
C. Content filtering
D. Encryption type and strength
Answer: B
Explanation:
MAC Filtering (or EUI filtering, or layer 2 address filtering) is a security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network.
QUESTION 245
Which of the following performs authentication and provides a secure connection by using 3DES to encrypt all information between two systems?
A. HTTPS
B. SSH
C. RSA
D. SSL
Answer: B
Explanation:
