Cisco CCNA 200-301 Questions & Answers

• Question 391:

  Refer to the exhibit

  

  A new VLAN and switch are added to the network. A remote engineer configures OldSwitch and must ensure that the configuration meets these requirements:

  1.

  accommodates current configured VLANs

  2.

  expands the range to include VLAN 20

  3.

  allows for IEEE standard support for virtual LANs

  Which configuration on the NewSwitch side of the link meets these requirements?

  A. switch port mode dynamicchannel group 1 mode activeswitchport trunk allowed vlan 5,10,15, 20

  B. no switchport mode trunkswitchport trunk encapsulation islswitchport mode access vlan 20

  C. switchport nonegotiateno switchport trunk allowed vlan 5,10switchport trunk allowed vlan 5,10,15,20

  D. no switchport trunk encapsulation islswitchport trunk encapsulation dot1qswitchport trunk allowed vlan add 20

  Correct Answer: D

• Question 392:

  Refer to the exhibit.

  

  A network engineer is adding another physical interface as a new member to the existing Port-Channel1 bundle. Which command set must be configured on the new interface to complete the process?

  A. no switchportchannel group 1 mode active

  B. no switchportchannel-group 1 mode on

  C. switchport mode trunkchannel-group 1 mode active

  D. switchportswitchport mode trunk

  Correct Answer: A

  because it says"R" we know its a layer three port channel meaning we need the no swtchport command and this is a Lacp so it would us active / passive

• Question 393:

  Refer to the exhibit

  

  SW_1 and SW_12 represent two companies that are merging. They use separate network vendors. The VLANs on both sides have been migrated to share IP subnets.

  Which command sequence must be issued on both sides to join the two companies and pass all VLANs between the companies?

  A. switchport mode trunkswitchport trunk encapsulation dot1q

  B. switchport mode trunkswitchport trunk allowed vlan allswitchport dot1q ethertype 0800

  C. switchport mode dynamic desirableswitchport trunk allowed vlan allswitchport trunk native vlan 7

  D. switchport dynamic autoswitchport nonegotiate

  Correct Answer: A

  purpose is to change the encapsulation to dot1q because isl is a Cisco proprietary protocol

• Question 394:

  Refer to the exhibit.

  

  What is occurring on this switch?

  A. Frames are dropped after 16 failed transmission attempts

  B. The internal transmit buffer is overloaded

  C. A high number of frames smaller than 64 bytes are received

  D. An excessive number of frames greater than 1518 bytes are received

  Correct Answer: A

  The retransmission algorithm helps to ensure that the packets do not retransmit at the same time. However, if the two devices retry at nearly the same time, packets can collide again; the process repeats until either the packets finally pass onto the network without collisions, or 16 consecutive collisions occur and the packets are discarded.

• Question 395:

  Which two host addresses are reserved for private use within an enterprise network? (Choose two.)

  A. 10.172.76.200

  B. 12.17.1.20

  C. 172.15.2.250

  D. 172.31.255.100

  E. 192.169.32.10

  Correct Answer: AD

  Class B IP addresses. Configurations range from 172.16.0.0 to 172.31.255.255

• Question 396:

  What are two reasons to configure PortFast on a switch port attached to an end host? (Choose two.)

  A. to block another switch or host from communicating through the port

  B. to enable the port to enter the forwarding state immediately when the host boots up

  C. to prevent the port from participating in Spanning Tree Protocol operations

  D. to protect the operation of the port from topology change processes

  E. to limit the number of MAC addresses learned on the port to 1

  Correct Answer: BD

  Though PortFast is enabled the port still participates in STP https://www.arubanetworks.com/techdocs/ArubaOS_80_Web_Help/Content/ArubaFrameStyles/Network_Parameters/Portfast%20and%20BPDU%20Guard.htm

• Question 397:

  A network administrator wants the syslog server to filter incoming messages into different files based on their importance. Which filtering criteria must be used?

  A. message body

  B. level

  C. facility

  D. process ID

  Correct Answer: B

• Question 398:

  Which interface or port on the WLC is the default for in-band device administration and communications between the controller and access points?

  A. console port

  B. management interface

  C. virtual interface

  D. service port

  Correct Answer: B

  The management interface is the default interface for in-band management of the controller and connectivity to enterprise services such as AAA servers. It is also used for communications between the controller and access points, for all CAPWAP or intercontroller mobility messaging and tunneling traffic.

• Question 399:

  Refer to the exhibit.

  

  A network administrator configures the CPE to provide internet access to the company headquarters. Traffic must be load-balanced via ISP1 and ISP2 to ensure redundancy. Which two command sets must be configured on the CPE router? (Choose two.)
