What is the most compressed representation of the IPv6 address 2001:0000:0000:abcd:0000:0000:0000:0001? 2001:0:abcd::1 2001:0:0:abcd::1 2001::abcd::1 2001:0000:abcd::1 2001::abcd:0:1

2001:0:0:abcd::1

What is the dotted decimal representation of the IPv4 address 11001011.00000000.01110001.11010011? 192.0.2.199 198.51.100.201 203.0.113.211 209.165.201.223

203.0.113.211

A site administrator has been told that a particular network at the site must accommodate 126 hosts. Which subnet mask would be used that contains the required number of host bits? 255.255.255.0 255.255.255.128 255.255.255.224 255.255.255.240

255.255.255.128

How many valid host addresses are available on an IPv4 subnet that is configured with a /26 mask? 254 190 192 62 64

62

What are three characteristics of multicast transmission? (Choose three.) The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255. A single packet can be sent to a group of hosts. Multicast transmission can be used by routers to exchange routing information. Routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255. Computers use multicast transmission to request IPv4 addresses. Multicast messages map lower layer addresses to upper layer addresses.

A single packet can be sent to a group of hosts. Multicast transmission can be used by routers to exchange routing information. Routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255.

Refer to the exhibit. If host A sends an IP packet to host B, what will the destination address be in the frame when it leaves host A? DD:DD:DD:DD:DD:DD 172.168.10.99 CC:CC:CC:CC:CC:CC 172.168.10.65 BB:BB:BB:BB:BB:BB AA:AA:AA:AA:AA:AA

BB:BB:BB:BB:BB:BB

Which range of link-local addresses can be assigned to an IPv6-enabled interface? FEC0::/10 FDEE::/7 FE80::/10 FF00::/8

FE80::/10

What purpose does NAT64 serve in IPv6? It converts IPv6 packets into IPv4 packets. It translates private IPv6 addresses into public IPv6 addresses. It enables companies to use IPv6 unique local addresses in the network. It converts regular IPv6 addresses into 64-bit addresses that can be used on the Internet. It converts the 48-bit MAC address into a 64-bit host address that can be used for automatic host addressing.

It converts IPv6 packets into IPv4 packets.

What will a host on an Ethernet network do if it receives a frame with a destination MAC address that does not match its own MAC address? It will discard the frame. It will forward the frame to the next host. It will remove the frame from the media. It will strip off the data-link frame to check the destination IP address.

It will discard the frame.

Refer to the exhibit. What will be the result of entering this configuration the next time a network administrator connects a console cable to the router and no additional commands have been entered? The administrator will be required to enter Cisco123. The administrator will be required to enter Cisco234. The administrator will be required to enter Cisco789. The administrator will be presented with the R1> prompt.

The administrator will be presented with the R1> prompt.

What addresses are mapped by ARP? destination MAC address to a destination IPv4 address destination IPv4 address to the source MAC address destination IPv4 address to the destination host name destination MAC address to the source IPv4 address

destination MAC address to a destination IPv4 address

What are two services provided by the OSI network layer? (Choose two.) performing error detection routing packets toward the destination encapsulating PDUs from the transport layer placement of frames on the media collision detection

routing packets toward the destination encapsulating PDUs from the transport layer

Which frame forwarding method receives the entire frame and performs a CRC check to detect errors before forwarding the frame? cut-through switching store-and-forward switching fragment-free switching fast-forward switching

store-and-forward switching

What are two functions of NVRAM? (Choose two.) to store the routing table to retain contents when power is removed to store the startup configuration file to contain the running configuration file to store the ARP table

to retain contents when power is removed to store the startup configuration file
