Question: Refer to the exhibit. Which three statements correctly describe Network Device A?
A. With a network wide mask of 255.255.255.128, each interface does not require an IP address.
B. With a network wide mask of 255.255.255.128, each interface does require an IP address on a unique IP subnet.
C. With a network wide mask of 255.255.255.0, must be a Layer 2 device for the PCs to communicate with each other.
D. With a network wide mask of 255.255.255.0, must be a Layer 3 device for the PCs to communicate with each other.
E. With a network wide mask of 255.255.254.0, each interface does not require an IP address.
Correct answer: B D E

Question: Which DSCP Assured Forwarding value provides the worst drop and worst queue performance?
A. AF41
B. AF43
C. AF11
D. AF13
Correct answer: D
Your answer: C
Explanation: DiffServ defines the Assured Forwarding (AF) Differentiated Services Code Point (DSCP) as a set of values that are used with each other. Traffic is separated into four
different classes and three different drop priorities, resulting in a grid of 12 different AF values that are marked based on the intended use of the traffic. The AF13 marking results in traffic
having the lowest queue priority and the highest drop probability.
Question: Refer to the diagram. What method of authentication is being used?
A. Open authentication
B. CCMP
C. WEP
D. 802.1x
Correct answer: D
Your answer: B
Explanation: The figure shows the use of EAP between the laptop (the supplicant) and the WLC (the authenticator). Those flows implus the use of the 802.1x/EAP authentication method.
1- The device authenticates with the AP, and the actual client authentication process is done with an external authentication server through the WLC.
2- The WLC controls the user access with 802.1x and communicates with the authentication server .
The incorrect answers do not happen to use the processes shown in the figure. For instance, open authentication does not authenticate the client. In the past, WEP provided encryption
and authentication, but was deprecated long ago. CCMP works as a useful current encryption method, but it does not use the protocols shown in the figure.
Question: A switch’s port Gi0/1 has been correctly enabled with port security. The configuration sets the violation mode to restrict. A frame that violates the port security policy enters the
interface, followed by a frame that does not. Which of the following answers correctly describe what happens in this scenario?
A. The switch puts the interface into an err-disabled state when the first frame arrives.
B. The switch generates syslog messages about the violating traffic for the first frame.
C. The switch increments the violation counter for Gi0/1 by 1.
D. The switch discards both the first and second frame.
Correct answer: B C
Your answer: D
Explanation: First, about the two incorrect answers: When in restrict mode, the arrival of a frame that violates the port security policy does not cause the switch to put the interface into errdisabled state. It does cause the switch to discard any frames that violate the policy, but it leaves the interface up, and does not discard frames that do not violate the security policy, like
the second frame that arrives.
Regarding the two correct answers, a port in port security restrict does cause the switch to issue log messages for a violating frame, send SNMP traps about that same event (if SNMP is
configured), and to increment the counter of violating frames.
Question: What statements accurately describe the characteristics of switches?
A. Large frame buffers provide storage of more received frames before having to start dropping them
B. Low per-port cost makes 24 and 48 port switches common; large enterprise switches can support hundreds of ports
C. High port density provides the ability of accommodating fewer users per segment, increasing the average available bandwidth per user
D. Port speeds of 100 Mbps are expected yet 1 Gbps or 10 Gbps are more common
E. Fast internal switching uses a fast internal bus or a shared memory, which affects the performance of the switch

Question: Which physical layer media are used today for connecting network devices (switches and routers) together in a LAN?
A. Coaxial
B. Twisted copper pair
C. Fiber optic
D. Wireless
Correct answer: B C
Your answer: B
Explanation:
Question: Which QoS feature is typically used outbound to an ISP to reduce the amount of traffic that is dropped by exceeding the purchased rate?
A. Traffic shaping
B. Traffic policing
C. Traffic limiting
D. Traffic classification
Correct answer: A
Your answer: B
Explanation: Often a connection to an Internet service provider (ISP) is physically connected with a technology that exceeds the purchased rate. To control the amount of traffic that is
allowed onto their network, ISPs limit the rate that traffic is allowed to flow into the network. This is done with traffic policers; to limit the amount of traffic that could potentially be dropped
by the ISP’s policer, an enterprise could choose to shape the traffic going out of their network and to the ISP.
Question: Which two protocols are used by bridges and/or switches to prevent loops in a layer 2 network?
A. 802.1d
B. VTP
C. 802.1q
D. STP
E. SAP

E. It is not associated with any VLAN by default
F. It is only available with ISL encapsulation
G. It must be configured as VLAN 1 if used
Correct answer: A B C
Your answer: A B D
Explanation:
Question: What can you verify on a Cisco IOS ISR with the ”show ip interface” command?
