Cisco CCNA 200-301 Questions & Answers

• Question 1271:

  Which design element is a best practice when deploying an 802.11b wireless infrastructure?

  A. allocating nonoverlapping channels to access points that are in close physical proximity to one another

  B. disabling TCP so that access points can negotiate signal levels with their attached wireless devices

  C. configuring access points to provide clients with a maximum of 5 Mbps

  D. setting the maximum data rate to 54 Mbps on the Cisco Wireless LAN Controller

  Correct Answer: A

  Selecting the proper WiFi channel can significantly improve your WiFi coverage and performance. In the 2.4 GHz band, 1, 6, and 11 are the only non-overlapping channels. Selecting one or more of these channels is an important part of setting up your network correctly.

• Question 1272:

  A Cisco IP phone receives untagged data traffic from an attached PC. Which action is taken by the phone?

  A. It drops the traffic.

  B. It allows the traffic to pass through unchanged.

  C. It tags the traffic with the native VLAN.

  D. It tags the traffic with the default VLAN.

  Correct Answer: B

  Untagged traffic from the device attached to the Cisco IP Phone passes through the phone unchanged, regardless of the trust state of the access port on the phone.

• Question 1273:

  Refer to Exhibit.

  

  How does SW2 interact with other switches in this VTP domain?

  A. It transmits and processes VTP updates from any VTP clients on the network on its trunk ports.

  B. It processes VTP updates from any VTP clients on the network on its access ports.

  C. It receives updates from all VTP servers and forwards all locally configured VLANs out all trunk ports.

  D. It forwards only the VTP advertisements that it receives on its trunk ports.

  Correct Answer: D

  The VTP mode of SW2 is transparent so it only forwards the VTP updates it receives to its trunk links without processing them. Reference: https://www.cisco.com/c/en/us/support/docs/lan-switching/vtp/10558-21.html

• Question 1274:

  Refer to the exhibit.

  

  Based on the LACP neighbor status, in which mode is the SW1 port channel configured?

  A. mode on

  B. active

  C. passive

  D. auto

  Correct Answer: B

  From the neighbor status, we notice the “Flags” are SP. “P” here means the neighbor is in Passive mode. In order to create an Etherchannel interface, the (local) SW1 ports should be in Active mode. Moreover, the “Port State” in the exhibit is “0x3c” (which equals to “00111100″ in binary format). Bit 3 is “1” which means the ports are synchronizing -> the ports are working so the local ports should be in Active mode.

• Question 1275:

  Two switches are connected and using Cisco Dynamic Trunking Protocol. SW1 is set to Dynamic Auto and SW2 is set to Dynamic Desirable. What is the result of this configuration?

  A. The link becomes an access port.

  B. The link is in an error disabled state.

  C. The link is in a down state.

  D. The link becomes a trunk port.

  Correct Answer: D

  Dynamic Auto — Makes the Ethernet port willing to convert the link to a trunk link. The port becomes a trunk port if the neighboring port is set to trunk or dynamic desirable mode. This is the default mode for some switchports. Dynamic Desirable — Makes the port actively attempt to convert the link to a trunk link. The port becomes a trunk port if the neighboring Ethernet port is set to trunk, dynamic desirable or dynamic auto mode.

• Question 1276:

  Refer to the exhibit.

  

  Which command provides this output?

  A. show ip route

  B. show cdp neighbor

  C. show ip interface

  D. show interface

  Correct Answer: B

• Question 1277:

  Which mode must be used to configure EtherChannel between two switches without using a negotiation protocol?

  A. active

  B. on

  C. auto

  D. desirable

  Correct Answer: B

  The Static Persistence (or “on” mode) bundles the links unconditionally and no negotiation protocol is used. In this mode, neither PAgP nor LACP packets are sent or received.

• Question 1278:

  Which mode allows access points to be managed by Cisco Wireless LAN Controllers?

  A. bridge

  B. lightweight

  C. mobility express

  D. autonomous

  Correct Answer: B

  A Lightweight Access Point (LAP) is an AP that is designed to be connected to a wireless LAN (WLAN) controller (WLC). APs are “lightweight,” which means that they cannot act independently of a wireless LAN controller (WLC). The WLC manages the AP configurations and firmware. The APs are “zero touch” deployed, and individual configuration of APs is not necessary.

• Question 1279:

  Which two values or settings must be entered when configuring a new WLAN in the Cisco Wireless LAN Controller GUI? (Choose two.)

  A. QoS settings

  B. IP address of one or more access points

  C. SSID

  D. profile name

  E. management interface settings

  Correct Answer: CD

  SSID and Profile Name would be used for identification and would be important when creating a new WLAN

• Question 1280:

  Which command is used to specify the delay time in seconds for LLDP to initialize on any interface?

  A. lldp timer

  B. lldp tlv-select

  C. lldp reinit

  D. lldp holdtime

  Correct Answer: C

  1.

  lldp holdtime seconds: Specify the amount of time a receiving device should hold the information from your device before discarding it

  2.

  lldp reinit delay: Specify the delay time in seconds for LLDP to initialize on an interface

  3.

  lldp timer rate: Set the sending frequency of LLDP updates in seconds
