Demo Questions

Question 1

Which network configuration can you use to segregate broadcast traffic for two different departments in your organization?

  • A: Configure two VTP domains and configure the switches in transparent mode.
  • B: Enable spanning-tree load balancing.
  • C: Implement switch port security on designated ports.
  • D: Configure a separate VLAN for each department.

Correct Answer: D




Question 2

Which keyword in a NAT configuration enables the use of one outside IP address for multiple inside hosts?

  • A: source
  • B: static
  • C: pool
  • D: overload

Correct Answer: D




Question 3

Which NAT term is defined as a group of addresses available for NAT use?

  • A: NAT pool
  • B: dynamic NAT
  • C: static NAT
  • D: one-way NAT

Correct Answer: A




Question 4

  

Refer to the exhibit. The enterprise has decided to use the network address 172.16.0.0. The network administrator needs to design a classful addressing scheme to accommodate the three subnets, with 30, 40, and 50 hosts, as shown. Which subnet mask would accommodate this network?

  • A: 255.255.255.224
  • B: 255.255.255.240
  • C: 255.255.255.252
  • D: 255.255.255.248
  • E: 255.255.255.192

Correct Answer: E

Subnet mask A i.e. 255.255.255.192 with CIDR of /26 which means 64 hosts per subnet which are sufficient to accommodate even the largest subnet of 50 hosts. 

  




Question 5

  

Refer to the exhibit. The network administrator is testing connectivity from the branch router to the newly installed application server. 
Which reason is the most likely for the first ping having a success rate of only 60 percent?

  • A: The branch router LAN interface should be upgraded to FastEthernet.
  • B: The branch router had to resolve the application server MAC address.
  • C: The network is likely to be congested, with the result that packets are being intermittently dropped.
  • D: There is a short delay while NAT translates the server IP address.
  • E: A routing table lookup delayed forwarding on the first two ping packets.

Correct Answer: B

The first time out is due for the time it took for the router to issue an ARP and get the MAC address associated with the 192.168.2.167 IP address.  Once this ARP was resolved, the other pings were successful.




Question 6

  

Refer to the topology and switching table shown in the graphic. Host B sends a frame to Host C. Which option describes what the switch will do with the frame?

  • A: send an ICMP Host Unreachable message to Host B
  • B: return the frame to Host B
  • C: drop the frame
  • D: send the frame out all ports except port 0/2
  • E: record the destination MAC address in the switching table and send the frame directly to Host C
  • F: send an ARP request for Host C

Correct Answer: D

  

  




Question 7

An administrator has connected devices to a switch and, for security reasons, wants the dynamically learned MAC addresses from the address table added to the running configuration. Which action must be taken to accomplish this?

  • A: Use the no switchport port-security command to allow MAC addresses to be added to the configuration.
  • B: Enable port security and use the keyword sticky.
  • C: Set the switchport mode to trunk and save the running configuration.
  • D: Use the switchport protected command to have the MAC addresses added to the configuration.

Correct Answer: B

One can configure MAC addresses to be sticky. These can be dynamically learned or manually configured, stored in the address table, and added to the running configuration. If these addresses are saved in the configuration file, the interface does not need to dynamically relearn them when the switch restarts.




Question 8

Which port-security feature allows a switch to learn MAC addresses dynamically and add them to the running configuration?

  • A: security violation restrict mode
  • B: switch port protection
  • C: sticky learning
  • D: security violation protect mode

Correct Answer: C

You can configure an interface to convert the dynamic MAC addresses to sticky secure MAC addresses and to add them to the running configuration by enabling sticky learning. To enable sticky learning, enter the switchport port-security mac-address sticky interface configuration command. When you enter this command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses.

Question 9

Which statement about 6to4 tunneling is true?

  • A: One tunnel endpoint must be configured with IPv4 only.
  • B: Both tunnel endpoint must be configured with IPv4 only.
  • C: It establishes a point-to-point tunnel.
  • D: Both tunnel endpoints must support IPv4 and IPv6.

Correct Answer: D




Question 10

An administrator is working with the 192.168.4.0 netwrok, which has been subnetted with a /26 mask. 
Which two addresses can be assigned to hosts within the same subnet? (Choose two.)

  • A: 192.168.4.67
  • B: 192.168.4.61
  • C: 192.168.4.128
  • D: 192.168.4.132
  • E: 192.168.4.125
  • F: 192.168.4.63

Correct Answer: AE

Only the values of host with 67 and 125 fall within the range of /26 CIDR subnet mask, all others lie beyond it.
