Cisco 200-301 Online Questions & Answers

• Question 231:

  What is the purpose of classifying network traffic in QoS?

  A. configures traffic-matching rules on network devices
  B. services traffic according to its class
  C. identifies the type of traffic that will receive a particular treatment
  D. writes the class identifier of a packet to a dedicated field in the packet header
  C. identifies the type of traffic that will receive a particular treatment

  ---

  The purpose of classifying network traffic in Quality of Service (QoS) is to categorize and prioritize different types of network traffic based on their characteristics or requirements. By classifying traffic, QoS allows network administrators to apply differentiated treatment to various types of data flows to ensure that critical or sensitive traffic receives the necessary resources and quality of service.

• Question 232:

  DRAG DROP

  Drag and drop the characteristic from the left onto the IPv6 address type on the right.

• Question 233:

  Refer to the exhibit.

  

  An engineer is updating the management access configuration of switch SW1 to allow secured, encrypted remote configuration. Which two commands or command sequences must the engineer apply to the switch? (Choose two.)

  A. SW1(config)#enable secret ccnaTest123
  B. SW1(config)#username NEW secret R3mote123
  C. SW1(config)#line vty 0 15 SW1(config-line)#transport input ssh
  D. SW1(config)#crypto key generate rsa
  E. SW1(config)#interface f0/1 SW1(config-if)#switchport mode trunk
  A. SW1(config)#enable secret ccnaTest123
  C. SW1(config)#line vty 0 15 SW1(config-line)#transport input ssh

  SSH test on PT without the enable secret below and it really shows that you can't access:

  Cisco Packet Tracer PC Command Line 1.0

  C:\>ssh -l pablo 10.0.32.2

  Password: xxx

  SW3>

  SW3>enable

  % No password set.

  SW3>

• Question 234:

  What does a router do when it is configured with the default DNS lookup settings, and a URL is entered on the CLI?

  A. It continuously attempts to resolve the URL until the command is cancelled.
  B. It initiates a ping request to the URL.
  C. It prompts the user to specify the desired IP address.
  D. It attempts to query a DNS server on the network.
  D. It attempts to query a DNS server on the network.

• Question 235:

  Refer to the exhibit.

  

  An administrator is tasked with configuring a voice VLAN. What is the expected outcome when a Cisco phone is connected to the GigabitEthernet 3/1/4 port on a switch?

  A. The phone and a workstation that is connected to the phone do not have VLAN connectivity.
  B. The phone sends and receives data in VLAN 50, but a workstation connected to the phone sends and receives data in VLAN 1.
  C. The phone sends and receives data in VLAN 50, but a workstation connected to the phone has no VLAN connected.
  D. The phone and a workstation that is connected to the phone send and receive data in VLAN 50.
  B. The phone sends and receives data in VLAN 50, but a workstation connected to the phone sends and receives data in VLAN 1.

• Question 236:

  A network engineer must configure two new subnets using the address block 10.70.128.0/19 to meet these requirements:

  1.

  The first subnet must support 24 hosts.

  2.

  The second subnet must support 472 hosts.

  3.

  Both subnets must use the longest subnet mask possible from the address block.

  Which two configurations must be used to configure the new subnets and meet a requirement to use the first available address in each subnet for the router interfaces? (Choose two.)

  A. interface vlan 1148 ip address 10.70.148.1 255.255.254.0
  B. interface vlan 3002 ip address 10.70.147.17 255.255.255.224
  C. interface vlan 4722 ip address 10.70.133.17 255.255.255.192
  D. interface vlan 1234 ip address 10.70.159.1 255.255.254.0
  E. interface vlan 155 ip address 10.70.155.65 255.255.255.224
  A. interface vlan 1148 ip address 10.70.148.1 255.255.254.0
  E. interface vlan 155 ip address 10.70.155.65 255.255.255.224

• Question 237:

  A client experiences slow throughput from a server that is directly connected to the core switch in a data center. A network engineer finds minimal latency on connections to the server, but data transfers are unreliable, and the output of the show Interfaces counters errors command shows a high FCS-Err count on the interface that is connected to the server. What is the cause of the throughput issue?

  A. high bandwidth usage
  B. a physical cable fault
  C. a speed mismatch
  D. a cable that is too long
  B. a physical cable fault

  ---

  The cause of the throughput issue described in the scenario is a physical cable fault.

  The scenario mentions that the network engineer found minimal latency on connections to the server, but data transfers are unreliable, and the output of the "show interfaces counters errors" command shows a high FCS-Err count on the interface that is connected to the server. FCS-Err (Frame Check Sequence error) indicates that there is a physical issue with the cable, such as noise or interference, that is causing the data transfer errors.

  A speed mismatch or high bandwidth usage may cause slow throughput or delays, but it would not cause FCS-Err errors. Similarly, a cable that is too long may cause signal attenuation, but it would not cause FCS-Err errors.

• Question 238:

  Refer the exhibit.

  

  What is the cause of poor performance on router R19?

  A. excessive collisions
  B. speed and duplex mismatch
  C. port oversubscription
  D. excessive CRC errors
  C. port oversubscription

• Question 239:

  Which protocol is used to securely manage network devices over an encrypted connection?

  A. Telnet
  B. SNMPv2
  C. SSH
  D. HTTP
  C. SSH

  ---

  Secure Shell (SSH) provides encrypted remote CLI access to network devices. Unlike Telnet and HTTP, SSH protects authentication credentials and management traffic from interception.

• Question 240:

  Refer to the exhibit.

  

  A network administrator has been tasked with securing VTY access to a router. Which access-list entry accomplishes this task?

  B. access-list 101 permit tcp 10.1.1.0 0.0.0.255 172.16.1.0 0.0.0.255 eq scp
