Cisco 200-301 Online Questions & Answers

• Question 1511:

  A network administrator is asked to configure VLANS 2, 3 and 4 for a new implementation. Some ports must be assigned to the new VLANS with unused remaining. Which action should be taken for the unused ports?

  A. configure port in the native VLAN
  B. configure ports in a black hole VLAN
  C. configure in a nondefault native VLAN
  D. configure ports as access ports
  B. configure ports in a black hole VLAN

  ---

  A black hole VLAN is a virtual LAN that is configured on a network switch, but it is not connected to any device or port. Traffic that is sent to a port in a black hole VLAN is discarded, effectively "sinking" into a "black hole." Black hole VLANs are sometimes used as a security measure to isolate or quarantine certain ports or devices, or to prevent unauthorized access or traffic on a network.

• Question 1512:

  Refer to the exhibit.

  Topology

  

  Tasks

  Refer to the topology. All physical cabling is in place. Configure local users accounts, modify the Named ACL (NACL), and configure DHCP Snooping. The current contents of the NACL must remain intact.

  Task 1

  Configure a local account on Gw1 with telnet access only on virtual ports 0-4. Use the following information:

  1. Username: wheel

  2. Password: lock3path

  3. Algorithm type: Scrypt

  4. Privilege level: Exec mode

  Task 2

  Configure and apply a NACL on Gw1 to control network traffic from VLAN 10:

  1. Name: CORP_ACL

  2. Allow BOOTP and HTTPS

  3. Restrict all other traffic and log the ingress interface, source MAC address, the packet’s source and destination IP addresses, and ports

  Task 3

  Configure Sw1:

  1. Enable DNCP Snooping for VLAN 10

  2. Disable DHCP Option-82 data insertion

  3. Enable DHCP Snooping MAC address verification

  4. Enable trusted interfaces

  

  A. Check the Explanation below
  B. Place Holder
  C. Place Holder
  D. Place Holder
  A. Check the Explanation below

  ---

  Explanation

  GW1:

  R1(config)#username wheel privilege 15 algorithm-type scrypt secret lock3path

  line vty 0 4

  login local

  transport input telnet

  task2 on GW1: bootp = udp; https = tcp

  access-list CORP_ACL permit udp any any eq bootp (67,68)

  access-list CORP_ACL permit tcp any any eq https (443)

  access-list CORP_ACL deny ip any any log

  on the router Gw1 find the gateway-subinterface for Vlan10 (router ont the stick) and apply ACL

  Gw1(config-subif)#ip access-group CORP_ACL in

  task3 on Sw1:

  Sw1(config)#ip dhcp snooping vlan 10

  Sw1(config)#ip dhcp snooping verify mac-address

  Sw1(config)#no ip dhcp snooping information option

  Sw1(config)interface e0/2

  Sw1(config-if)#ip dhcp snooping trust

• Question 1515:

  What is a characteristic of frame switching?

  A. rewrites the source and destination MAC address
  B. performs a lookup to learn the destination interface
  C. sends a retransmission request when a new frame is received
  D. inspects and drops frames from unknown destinations
  B. performs a lookup to learn the destination interface

• Question 1516:

  What describes a northbound REST API for SDN?

  A. network-element-facing interface for GET, POST, PUT, and DELETE methods
  B. application-facing interface for SNMP GET requests
  C. application-facing interface for GET, POST, PUT, and DELETE methods
  D. network-element-facing interface for the control and data planes
  C. application-facing interface for GET, POST, PUT, and DELETE methods

  ---

  A northbound REST API in the context of SDN refers to the application-facing interface that uses the HTTP methods GET, POST, PUT, and DELETE to interact with the SDN controller. Here's a breakdown of how these methods are typically used:

  1. GET Method: The GET method is used to retrieve information from the SDN controller. Applications can send a GET request to the REST API endpoint to obtain information about the network topology, device status, flow entries, statistics, or any other data exposed by the controller. The response typically contains the requested information in a format such as JSON or XML.

  2. POST Method: The POST method is used to create new resources or initiate actions on the SDN controller. Applications can send a POST request to the REST API endpoint to create a new flow entry, configure network devices, or trigger specific operations within the SDN infrastructure. The request payload contains the necessary data to create or execute the desired action.

  3. PUT Method: The PUT method is used to update or replace existing resources in the SDN controller. Applications can send a PUT request to the REST API endpoint to modify the configuration of network devices, update flow entries, or change the state of specific network components. The request payload contains the updated data to replace the existing resource.

  4. DELETE Method: The DELETE method is used to remove resources from the SDN controller. Applications can send a DELETE request to the REST API endpoint to delete flow entries, remove network device configurations, or trigger the deletion of specific network components. The request typically includes the identification of the resource to be deleted.

• Question 1518:

  Refer to the exhibit.

  

  A packet sourced from 10.10.10.1 is destined for 10.10.8.14. What is the subnet mask of the destination route?

  A. 255.255.254.0
  B. 255.255.255.240
  C. 255.255.255.248
  D. 255.255.255.252
  B. 255.255.255.240

  ---

  255.255.255.240, means /28. The IP 10.10.8.14 falls within the 10.10.8.0/28 range, which is: 10.10.8.0 network ID - 10.10.8.15 Broadcast IP.

• Question 1519:

  Which SDN plane is responsible for forwarding traffic based on controller instructions?

  A. Application plane
  B. Management plane
  C. Control plane
  D. Data plane
  D. Data plane

  ---

  The data plane is responsible for forwarding packets based on rules installed by the SDN controller. It handles actual traffic movement, while the control plane determines how traffic should be forwarded.
