Pt. 6

What is the binary representation of 0xCA? 10111010 11010101 11001010 11011010

11001010

What subnet mask is needed if an IPv4 network has 40 devices that need IP addresses and address space is not to be wasted? 255.255.255.0 255.255.255.128 255.255.255.192 255.255.255.224 255.255.255.240

255.255.255.192

A network administrator wants to have the same subnet mask for three subnetworks at a small site. The site has the following networks and numbers of devices:Subnetwork A: IP phones - 10 addressesSubnetwork B: PCs - 8 addressesSubnetwork C: Printers - 2 addresses What single subnet mask would be appropriate to use for the three subnetworks? 255.255.255.0 255.255.255.240 255.255.255.248 255.255.255.252

255.255.255.240

How many usable IP addresses are available on the 192.168.1.0/27 network? 256 254 62 30 16 32

30

What network service resolves the URL entered on a PC to the IP address of the destination server? DNS DHCP FTP SNMP

DNS

Which two protocols operate at the highest layer of the TCP/IP protocol stack? (Choose two.) DNS Ethernet IP POP TCP UDP

DNS POP

What is one difference between the client-server and peer-to-peer network models? Only in the client-server model can file transfers occur. Every device in a peer-to-peer network can function as a client or a server. A peer-to-peer network transfers data faster than a transfer using a client-server network. A data transfer that uses a device serving in a client role requires that a dedicated server be present.

Every device in a peer-to-peer network can function as a client or a server.

What is the purpose of the command ping ::1? It tests the internal configuration of an IPv6 host. It tests the broadcast capability of all hosts on the subnet. It tests the multicast connectivity to all hosts on the subnet. It tests the reachability of the default gateway for the network.

It tests the internal configuration of an IPv6 host.

Which service provides dynamic global IPv6 addressing to end devices without using a server that keeps a record of available IPv6 addresses? stateful DHCPv6 SLAAC static IPv6 addressing stateless DHCPv6

SLAAC

Which networking model is being used when an author uploads one chapter document to a file server of a book publisher? peer-to-peer master-slave client/server point-to-point

client/server

At a minimum, which address is required on IPv6-enabled interfaces? link-local unique local site local global unicast

link-local

Which two functions are primary functions of a router? (Choose two.) packet forwarding microsegmentation domain name resolution path selection flow control

packet forwarding path selection

What are two characteristics shared by TCP and UDP? (Choose two.) default window size connectionless communication port numbering 3-way handshake ability to to carry digitized voice use of checksum

port numbering use of checksum

Which two commands can be used on a Windows host to display the routing table? (Choose two.) netstat -s route print show ip route netstat -r tracert

route print netstat -r

Why are port numbers included in the TCP header of a segment? to indicate the correct router interface that should be used to forward a segment to identify which switch ports should receive or forward the segment to determine which Layer 3 protocol should be used to encapsulate the data to enable a receiving host to forward the data to the appropriate application to allow the receiving host to assemble the packet in the proper order

to enable a receiving host to forward the data to the appropriate application
