New Question
When OSPF learns multiple paths to a network, how does it select a route?
A. It multiple the active K value by 256 to calculate the route with the lowest metric.
B. For each existing interface, it adds the metric from the source router to the destination to calculate the route with the lowest bandwidth.
C. It divides a reference bandwidth of 100 Mbps by the actual bandwidth of the existing interface to calculate the router with the lowest cost.
D. It count the umber of hops between the source router and the destination to determine the router with the lowest metric
Correct Answer: C
Explanation Explanation/Reference:
New Question
Refer to the Exhibit. After the switch configuration the ping test fails between PC A and PC B Based on the output for switch 1. Which error must be corrected?
A. There is a native VLAN mismatch
B. Access mode is configured on the switch ports.
C. The PCs are m the incorrect VLAN
D. All VLANs are not enabled on the trunk
Correct Answer: A
Explanation:
From the output we see the native VLAN of Switch1 on Gi0/1 interface is VLAN 1 while that of Switch2 is VLAN 99 so there would be a native VLAN mismatch.
New Question
Which command enables a router to become a DHCP client?
A. ip address dhcp
B. ip helper-address
C. ip dhcp pool
D. ip dhcp client
Correct Answer: A
Explanation:
If we want to get an IP address from the DHCP server on a Cisco device, we can use the command “ip address dhcp”. Note: The command “ip helper-address” enables a router to become a DHCP Relay Agent.
New Question
Which two encoding methods are supported by REST APIs? (Choose two)
A. YAML
B. JSON
C. EBCDIC
D. SGML
E. XML
Correct Answer: BE
Explanation:
The Application Policy Infrastructure Controller (APIC) REST API is a programmatic interface that uses REST architecture. The API accepts and returns HTTP (not enabled by default) or HTTPS messages that contain JavaScript Object Notation (JSON) or Extensible Markup Language (XML) documents.

New Question
Refer to the exhibit. What is the effect of this configuration?
A. All ARP packets are dropped by the switch
B. Egress traffic is passed only if the destination is a DHCP server.
C. All ingress and egress traffic is dropped because the interface is untrusted
D. The switch discard all ingress ARP traffic with invalid MAC-to-IP address bindings.
Correct Answer: D
Explanation:
Dynamic ARP inspection is an ingress security feature; it does not perform any egress checking.
New Question
In a CDP environment, what happens when the CDP interface on an adjacent device is configured without an IP address?
A. CDP becomes inoperable on that neighbor
B. CDP uses the IP address of another interface for that neighbor
C. CDP operates normally,but it cannot provide IP address information for that neighbor
D. CDP operates normally,but it cannot provide any information for that neighbor
Correct Answer: C
Explanation:
Although CDP is a Layer 2 protocol but we can check the neighbor IP address with the “show cdp neighbor detail” command. If the neighbor does not has an IP address then CDP still operates without any problem. But the IP address of that neighbor is not provided.
New Question
Refer to the exhibit. When PC 1 sends a packet to PC2,the packet has.
Which source and destination IP address when it arrives at interface Gi0/0 on router R2?
A. source 192.168.10.10 and destination 10.10.2.2
B. source 192.168.20.10 and destination 192.168.20.1
C. source 192.168.10.10 and destination 192.168.20.10
D. source 10.10.1.1 and destination 10.10.2.2
Correct Answer: C
Explanation:
The source and destination IP addresses of the packets are unchanged on all the way. Only source and destination MAC addresses are changed.
New Question
Which feature or protocol determines whether the QOS on the network is sufficient to support IP services?
A. LLDP
B. CDP
C. IP SLA
D. EEM
Correct Answer: C
Explanation:
IP SLA allows an IT professional to collect information about network performance in real time. Therefore it helps determine whether the QoS on the network is sufficient for IP services or not.
Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible subsystem that provides real-time network event detection and onboard automation. It gives you the ability to adapt the behavior of your network devices to align with your business needs.
New Question
An email user has been lured into clicking a link in an email sent by their company’s security organization. The webpage that opens reports that it was safe but the link could have contained malicious code. Which type of security program is in place?
A. Physical access control
B. Social engineering attack
C. brute force attack
D. user awareness
Correct Answer: D
Explanation:
This is a training program which simulates an attack, not a real attack (as it says “The webpage that opens reports that it was safe”) so we believed it should be called a “user awareness” program. Therefore the best answer here should be “user awareness”. This is the definition of “User awareness” from CCNA 200-301 Offical Cert Guide Book:
“User awareness: All users should be made aware of the need for data confidentiality to protect corporate information, as well as their own credentials and personal information. They should also be made aware of potential threats, schemes to mislead, and proper procedures to report security incidents. “
Note: Physical access control means infrastructure locations, such as network closets and data centers, should remain securely locked.
New Question
What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?
A. The Layer 2 switch drops the received frame
B. The Layer 2 switch floods packets to all ports except the receiving port in the given VLAN.
C. The Layer 2 switch sends a copy of a packet to CPU for destination MAC address learning.
D. The Layer 2 switch forwards the packet and adds the destination MAC address to its MAC address table
Correct Answer: B
Explanation:
If the destination MAC address is not in the CAM table (unknown destination MAC address), the switch sends the frame out all other ports that are in the same VLAN as the received frame. This is called flooding. It does not flood the frame out the same port on which the frame was received.
New Question
Refer to the exhibit. An engineer configured NAT translations and has verified that the configuration is correct.
Which IP address is the source IP? A. 10.4.4.4
B. 10.4.4.5
C. 172.23.103.10
D. 172.23.104.4
Correct Answer: A
Explanation:
The source IP address is the IP address of the sending packets so it is the “inside local” address.
New Question
Refer to the exhibit. The New York router is configured with static routes pointing to the Atlanta and Washington sites.
Which two tasks must be performed so that the Serial0/0/0 interfaces on the Atlanta and Washington routers can reach one another? (Choose two.)
A. Configure the ipv6 route 2012::/126 2023::1 command on the Washington router

D. Configure the ipv6 route 2023::/126 2012::2 command on the Atlanta router
E. Configure the ipv6 route 2012::/126 2023::2 command on the Washington router
Correct Answer: DE
Explanation:
The short syntax of static IPv6 route is:
ipv6 route <destination-IPv6-address> {next-hop-IPv6-address | exit-interface}
New Question

New Question
Which output displays a JSON data representation?
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: D
Explanation:
JSON data is written as name/value pairs.
A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value: “name”:”Mark”
JSON can use arrays. Array values must be of type string, number, object, array, boolean or null. For example:
{
“name”:”John”, “age”:30,
“cars”:[ “Ford”, “BMW”, “Fiat” ]
}
JSON can have empty object like “taskId”:{}
New Question
An engineer must configure a WLAN using the strongest encryption type for WPA2-PSK. Which cipher fulfills the configuration requirement?
A. WEP
B. RC4
C. AES
D. TKIP
Correct Answer: C
Explanation:
Many routers provide WPA2-PSK (TKIP), WPA2-PSK (AES), and WPA2-PSK (TKIP/AES) as options. TKIP is actually an older encryption protocol introduced with WPA to replace the very-insecure WEP encryption at the time. TKIP is actually quite similar to WEP encryption. TKIP is no longer considered secure, and is now deprecated. In other words, you shouldn’t be using it.
AES is a more secure encryption protocol introduced with WPA2 and it is currently the strongest encryption type for WPA2-PSK/
