Q27. Refer to the exhibit. Consider the IP address configuration shown from PC1. What is a description of the default gateway address?
- It is the IP address of the Router1 interface that connects the company to the Internet.
- It is the IP address of the Router1 interface that connects the PC1 LAN to Router1.
- It is the IP address of Switch1 that connects PC1 to other devices on the same LAN.
- It is the IP address of the ISP network device located in the cloud.
Explanation: The default gateway is used to route packets destined for remote networks. The default gateway IP address is the address of the first Layer 3 device (the router interface) that connects to the same network.
Q28. Which technology provides a solution to IPv4 address depletion by allowing multiple devices to share one public IP address?
- ARP
- DNS
- NAT
- SMB
- DHCP
- HTTP
Explanation: Network Address Translation (NAT) is a technology implemented within IPv4 networks. One application of NAT is to use a few public IP addresses to be shared by many internal network hosts which use private IP addresses. NAT removes the need for public addresses for every internal host. It therefore provides a solution to slow down the IPv4 address depletion.

Explanation: No answer description available for this question
Q33. What statement describes the function of the Address Resolution Protocol?
- ARP is used to discover the IP address of any host on a different network.
- ARP is used to discover the IP address of any host on the local network.
- ARP is used to discover the MAC address of any host on a different network.
- ARP is used to discover the MAC address of any host on the local network.
Explanation: When a PC wants to send data on the network, it always knows the IP address of the destination. However, it also needs to discover the MAC address of the destination. ARP is the protocol that is used to discover the MAC address of a host that belongs to the same network.

Q37. Which protocol translates a website name such as www.cisco.com into a network address?
- HTTP
- FTP
- DHCP
- DNS
Explanation: Domain Name Service translates names into numerical addresses, and associates the two. DHCP provides IP addresses dynamically to pools of devices. HTTP delivers web pages to users. FTP manages file transfers.
Q38. What is an advantage of using IPv6 ?
- more addresses for networks and hosts
- faster connectivity
- higher bandwidth
- more frequencies
Explanation: An IPv6 address is comprised of 128 bits as opposed to 32 bits in an IPv4 address. Thus it offers far more addresses for networks and hosts than an IPv4 address does.

Q41. A network technician is attempting to configure an interface by entering the following command: SanJose(config)# ip address 192.168.2.1 255.255.255.0. The command is rejected by the device. What is the reason for this?
- The command is being entered from the wrong mode of operation.
- The command syntax is wrong.
- The subnet mask information is incorrect.
- The interface is shutdown and must be enabled before the switch will accept the IP address.

Q47. Which connection provides a secure CLI session with encryption to a Cisco switch?
- a console connection
- an AUX connection
- a Telnet connection
- an SSH connection
Explanation: A CLI session using Secure Shell (SSH) provides enhanced security because SSH supports strong passwords and encryption during the transport of session data. The other methods support authentication but not encryption.
Q48. What are the three ranges of IP addresses that are reserved for internal private use? (Choose three.)
- 10.0.0.0/8
- 64.100.0.0/14
- 127.16.0.0/12
- 172.16.0.0/12
- 192.31.7.0/24
- 192.168.0.0/16
Explanation: No answer description available for this question
Q49. Refer to the exhibit. Match the packets with their destination IP address to the exiting interfaces on the router. (Not all targets are used.)
Explanation: Packets with a destination of 172.17.6.15 are forwarded through Fa0/0. Packets with a destination of 172.17.10.5 are forwarded through Fa1/1. Packets with a destination of 172.17.12.10 are forwarded through Fa1/0. Packets with a destination of 172.17.14.8 are forwarded through Fa0/1. Because network 172.17.8.0 has no entry in the routing table, it will take the gateway of last resort, which means that packets with a destination of 172.17.8.20 are forwarded through Serial0/0/0. Because a gateway of last resort exists, no packets will be dropped.
