CISCO part #3

A network administrator is adding a new LAN to a branch office. The new LAN must support 10 connected devices. What is the smallest network mask that the network administrator can use for the new network?

• 255.255.255.192
• 255.255.255.248
• 255.255.255.224
• 255.255.255.240

What technique is used with UTP cable to help protect against signal interference from crosstalk?

• wrapping a foil shield around the wire pairs
• twisting the wires together into pairs
• terminating the cable with special grounded connectors
• encasing the cables within a flexible plastic sheath

Refer to the exhibit. The network administrator has assigned the LAN of LBMISS an address range of 192.168.10.0. This address range has been subnetted using a /29 prefix. In order to accommodate a new building, the technician has decided to use the fifth subnet for configuring the new network (subnet zero is the first subnet). By company policies, the router interface is always assigned the first usable host address and the workgroup server is given the last usable host address. Which configuration should be entered into the properties of the workgroup server to allow connectivity to the Internet?

• IP address: 192.168.10.65 subnet mask: 255.255.255.240, default gateway: 192.168.10.76
• IP address: 192.168.10.38 subnet mask: 255.255.255.240, default gateway: 192.168.10.33
• IP address: 192.168.10.38 subnet mask: 255.255.255.248, default gateway: 192.168.10.33
• IP address: 192.168.10.41 subnet mask: 255.255.255.248, default gateway: 192.168.10.46
• IP address: 192.168.10.254 subnet mask: 255.255.255.0, default gateway: 192.168.10.1

Refer to the exhibit. The switches are in their default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway. Which network hosts will receive the ARP request sent by host A?

• only hosts B, C, and router R1
• only host D
• only router R1
• only hosts A, B, and C
• only hosts A, B, C, and D

Refer to the exhibit. A network engineer has been given the network address of 192.168.99.0 and a subnet mask of 255.255.255.192 to subnet across the four networks shown. How many total host addresses are unused across all four subnets?

• 88
• 200
• 72
• 224
• 158

Which connector is used with twisted-pair cabling in an Ethernet LAN?

• 
• 
• 
• 
• 

A client packet is received by a server. The packet has a destination port number of 22. What service is the client requesting?

• SSH
• SMB/CIFS
• HTTPS
• SLP

What characteristic describes an IPS?

• a tunneling protocol that provides remote users with secure access into the network of an organization
• a network device that filters access and traffic coming into a network
• software that identifies fast-spreading threats
• software on a router that filters traffic based on IP addresses or applications

What service is provided by DHCP?

• An application that allows real-time chatting among remote users.
• Allows remote access to network devices and servers.
• Dynamically assigns IP addresses to end and intermediary devices.
• Uses encryption to provide secure remote access to network devices and servers.

Refer to the exhibit. The switches have a default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for the default gateway. Which network devices will receive the ARP request sent by host A?

• only hosts B, C, and router R1
• only host D
• only hosts A, B, C, and D
• only hosts B and C
• only hosts A, B, and C
