Cisco 200-301 Online Questions & Answers

• Question 781:

  Which spanning-tree enhancement avoids the learning and listening states and immediately places ports in the forwarding state?

  A. BPDUfilter
  B. PortFast
  C. Backbonefast
  D. BPDUguard
  B. PortFast

  ---

  PortFast

  Spanning Tree Portfast causes layer 2 switch interfaces to enter forwarding state immediately, bypassing the listening and learning states. It should be used on ports connected directly to end hosts like servers or workstations. Note: If portfast isn't enabled, DHCP timeouts can occur while STP converges, causing more problems.

• Question 782:

  Which type of wireless encryption is used for WPA2 in pre-shared key mode?

  A. AES-128
  B. TKIP with RC4
  C. AES-256
  D. RC4
  A. AES-128

  ---

  The shared key may be 256 bits long but the encryption is 128 bits. https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access#:~:text=Each%20wireless%20network%20device%20encrypts,to%2063%20printable%20ASCII%20characters.

  CCNA Lab simulation

  Guidelines

  This is a lab item in which tasks will be performed on virtual devices.

  1. Refer to the Tasks tab to view the tasks for this lab item.

  2. Refer to the Topology tab to access the device console(s) and perform the tasks.

  3. Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

  4. All necessary preconfigurations have been applied.

  5. Do not change the enable password or hostname for any device.

  6. Save your configurations to NVRAM before moving to the next item.

  7. Click Next at the bottom of the screen to submit this lab and move to the next question.

  8. When Next is clicked, the lab doses and cannot be reopened.

  Topology

  

  Tasks

  Refer to the topology. All physical cabling is in place. Routers R3 and R4 are fully configured and inaccessible. Configure static routes for various connectivity to the ISP and the LAN, which resides on R4.

  1.Configure a default route on R2 to the ISP

  2.Configure a default route on R1 to the ISP

  3.Configure R2 with a route to the Server at 10.0.41.10

  4.Configure R1 with a route to the LAN that prefers R3 as the primary path to the LAN

• Question 786:

  Which fact must the engineer consider when implementing syslog on a new network?

  A. Syslog defines the software or hardware component that triggered the message.
  B. There are 16 different logging levels (0-15).
  C. The logging level defines the severity of a particular message.
  D. By default, all message levels are sent to the syslog server.
  C. The logging level defines the severity of a particular message.

• Question 787:

  Refer to the exhibit.

  

  How does router R1 handle traffic to 192.168.10.16?

  A. It selects the IS-IS route because it has the shortest prefix inclusive of the destination address
  B. It selects the RIP route because it has the longest prefix inclusive of the destination address
  C. It selects the OSPF route because it has the lowest cost
  D. It selects the EIGRP route because it has the lowest administrative distance
  B. It selects the RIP route because it has the longest prefix inclusive of the destination address

  ---

  1. Longest Prefix

  2. Administrative distance

  3. Metric https://packetlife.net/blog/2010/aug/16/route-preference/

• Question 788:

  Which IPsec mode encapsulates the entire IP packet?

  A. SSL VPN
  B. tunnel
  C. Q-in-Q
  D. transport
  B. tunnel

  ---

  In IPsec tunnel mode, the entire original IP packet, including the IP header and payload, is encapsulated and protected by a new IPsec header. This new packet is then transmitted between the IPsec endpoints (typically security gateways). Tunnel mode is typically used in site-to-site VPNs.

• Question 789:

  What is the purpose of a southbound API in a control based networking architecture?

  A. Facilities communication between the controller and the applications
  B. Facilities communication between the controller and the networking hardware
  C. allows application developers to interact with the network
  D. integrates a controller with other automation and orchestration tools.
  B. Facilities communication between the controller and the networking hardware

  ---

  The Southbound Interface

  In a controller-based network architecture, the controller needs to communicate to the networking devices. In most network drawings and architecture drawings, those network devices typically sit below the controller, as shown in Figure 16-5. There is an interface between the controller and those devices, and given its location at the bottom part of drawings, the interface came to be known as the southbound interface, or SBI, as labeled in Figure 16-5.

  

• Question 790:

  Which two components are needed to create an Ansible script that configures a VLAN on a switch? (Choose two.)

  A. cookbook
  B. task
  C. playbook
  D. model
  E. recipe
  B. task
  C. playbook

  ---

  Ansible Playbooks offer a repeatable, re-usable, simple configuration management and multi-machine deployment system, one that is well suited to deploying complex applications.

  A playbook is composed of one or more ‘plays’ in an ordered list. The terms ‘playbook’ and ‘play’ are sports analogies. Each play executes part of the overall goal of the playbook, running one or more tasks. Each task calls an Ansible module.

  A playbook runs in order from top to bottom. Within each play, tasks also run in order from top to bottom. Playbooks with multiple ‘plays’ can orchestrate multi-machine deployments, running one play on your webservers, then another play on your database servers, then a third play on your network infrastructure, and so on. At a minimum, each play defines two things:

  1. the managed nodes to target, using a pattern

  2. at least one task to execute
