Which statement describes a major characteristic of a local area network? A LAN is under one administrative control. A LAN is implemented in a corporation to connect all of its offices. A LAN connects remote users to the main corporate office. A LAN can contain up to 100 hosts.

A LAN is under one administrative control.

What are two functions of a router? (Choose two.) It controls the flow of data via the use of Layer 2 addresses. It provides segmentation at Layer 2. A router connects multiple IP networks. It determines the best path to send packets. It builds a routing table based on ARP requests.

A router connects multiple IP networks. It determines the best path to send packets.

A law firm uses DHCPv4 to dynamically assign IPv4 addresses for staff workstations. The DHCP policy specifies that the lease period is 7 days. A staff member returns to the office after 2 weeks of vacation. When the employee turns on the workstation, which DHCPv4 message is sent by the workstation to obtain a valid IPv4 address? DHCPACK broadcast message DHCPDISCOVER broadcast message DHCPOFFER unicast message DHCPREQUEST unicast message

DHCPREQUEST unicast message

A user is attempting to access http://www.cisco.com/ without success. Which two configuration values must be set on the host to allow this access? (Choose two.) DNS server default gateway source port number source MAC address HTTP server

DNS server default gateway

A company uses DHCP servers to dynamically assign IPv4 addresses to employee workstations. The address lease duration is set as 5 days. An employee returns to the office after an absence of one week. When the employee boots the workstation, it sends a message to obtain an IP address. Which Layer 2 and Layer 3 destination addresses will the message contain? FF-FF-FF-FF-FF-FF and IPv4 address of the DHCP server both MAC and IPv4 addresses of the DHCP server MAC address of the DHCP server and 255.255.255.255 FF-FF-FF-FF-FF-FF and 255.255.255.255

FF-FF-FF-FF-FF-FF and 255.255.255.255

Which two steps are required before SSH can be enabled on a Cisco router? (Choose two.) Give the router a host name and domain name. Create a banner that will be displayed to users when they connect. Enable SSH on the physical interfaces where the incoming connection requests will be received. Generate a set of secret keys to be used for encryption and decryption. Set up an authentication server to handle incoming connection requests.

Give the router a host name and domain name. Generate a set of secret keys to be used for encryption and decryption.

Which two application layer protocols manage the exchange of messages between a client with a web browser and a remote web server? (Choose two.) HTTPS HTML DHCP HTTP DNS

HTTPS HTTP

Which three acronyms/initialisms represent standards organizations? (Choose three.) MAC IEEE IANA OSI IETF TCP/IP

A user can access a file share resource on a server located in the same office but cannot access the internet. What is the possible cause? The default gateway address is misconfigured on the PC. The IPv4 address and subnet mask are misconfigured on the PC. The switch is malfunctioning. The DHCP server is disconnected.

The default gateway address is misconfigured on the PC.

The global configuration command ip default-gateway 172.16.100.1 is applied to a switch. What is the effect of this command? The switch can communicate with other hosts on the 172.16.100.0 network. The switch is limited to sending and receiving frames to and from the gateway 172.16.100.1. The switch will have a management interface with the address 172.16.100.1. The switch can be remotely managed from a host on another network.

The switch can be remotely managed from a host on another network.

A user is setting up a home wireless network. A global address is to be used in NAT translations for traffic flowing through the wireless router. How is this global address assigned? The host devices will select an unused IP address on the LAN for performing NAT through the wireless router. The default gateway IP address of the LAN device is used as the global address for NAT translations through the wireless router. The network administrator will choose an available IP address from the LAN and configure the global addressing of the wireless router. The wireless router will act as a DHCP client in order to receive global addressing from the ISP.

The wireless router will act as a DHCP client in order to receive global addressing from the ISP.

What are two characteristics of 802.11 wireless networks? (Choose two.) Stations can transmit at any time. They use CSMA/CA technology. They are collision-free networks. They use CSMA/CD technology. Collisions can exist in the networks.

They use CSMA/CA technology. Collisions can exist in the networks.

When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination? destination MAC address source IP address destination IP address source MAC address
