CCNA Cisco Certified Network Associate Practice Questions Part 3

How does using the service password-encryption command on a router provide additional security?

1. Refer to the exhibit.

Statements A, B, C, and D of ACL 10 have been entered in the shown order and applied to interface E0 inbound, to prevent all hosts (except those whose addresses are the first and last IP of subnet 172.21.1.128/28) from accessing the network. But as is, the ACL does not restrict anyone from the network. How can the ACL statements be re-arranged so that the system works as intended?

1. Refer to the exhibit.

An attempt to deny web access to a subnet blocks all traffic from the subnet. Which interface command immediately removes the effect of ACL 102?

Which Cisco Catalyst feature automatically disables the port in an operational PortFast upon receipt of a BPDU?

When you are troubleshooting an ACL issue on a router, which command would you use to verify which interfaces are affected by the ACL?

1. Refer to the configuration below:

A network administrator cannot establish a Telnet session with the indicated router. What is the cause of this failure?

Which statement about access lists that are applied to an interface is true?

Which item represents the standard IP ACL?

A network administrator is configuring ACLs on a Cisco router, to allow traffic from hosts on networks 192.168.146.0, 192.168.147.0, 192.168.148.0, and 192.168.149.0 only. Which two ACL statements, when combined, would you use to accomplish this task? (Choose 2)

What can be done to secure the virtual terminal interfaces on a router? (Choose 2)

Which two commands correctly verify whether port security has been configured on port FastEthernet 0/12 on a switch?

Refer to the diagram below:

The following commands are executed on interface fa0/1 of 2950Switch.

• 2950Switch(config-if)# switchport port-security
• 2950Switch(config-if)# switchport port-security mac-address sticky
• 2950Switch(config-if)# switchport port-security maximum 1

The Ethernet frame that is shown arrives on interface fa0/1. What two functions will occur when this frame is received by 2950Switch? (Choose 2)

What will be the result if the following configuration commands are implemented on a Cisco switch?

• Switch(config-if)# switchport port-security
• Switch(config-if)# switchport port-security mac-address sticky

Refer to the diagram below:

A network administrator attempts to ping Host2 from Host1 and receives the results that are shown. What is the problem?

Refer to the diagram below:

Hosts in network 192.168.2.0 are unable to reach hosts in network 192.168.3.0. Based on the output from RouterA, what are two possible reasons for the failure? (Choose 2)

Refer to the configuration below:

An administrator pings the default gateway at 10.10.10.1 and sees the output as shown. At which OSI layer is the problem?

Refer to the diagram below:

The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose 3)

Refer to the diagram.

The network shown in the diagram is experiencing connectivity problems. Which of the following will correct the problems? (Choose 2)

Refer to the diagram.

A problem with network connectivity has been observed. It is suspected that the cable connected to switch port Fa0/9 on Switch1 is disconnected. What would be an effect of this cable being disconnected?

Refer to the diagram.

HostA cannot ping HostB. Assuming routing is properly configured, what is the cause of this problem?

Which router IOS commands can be used to troubleshoot LAN connectivity problems? (Choose 3)

A network administrator is troubleshooting the OSPF configuration of routers R1 and R2. The routers cannot establish an adjacency relationship on their common Ethernet link.

The graphic shows the output of the show ip ospf interface e0 command for routers R1 and R2. Based on the information in the graphic, what is the cause of this problem?

In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?

What are three reasons to collect Netflow data on a company network?

What Netflow component can be applied to an interface to track IPv4 traffic?

What Cisco IOS feature can be enabled to pinpoint an application that is causing slow network performance?

What command visualizes the general NetFlow data on the command line?

What are three values that must be the same within a sequence of packets for Netflow to consider them a network flow? (Choose 3)

What are three factors a network administrator must consider before implementing Netflow in the network? (Choose 3)

Refer to the scenario.

If the devices produced the given output, what is the cause of the EtherChannel problem?

What are the benefits of using Netflow?
