QUESTION: 17

Which IPv6 address type provides communication between subnets and cannot route on the Internet?

link-local
unique local
multicast
global unicast

Answer(s): B

Explanation:

A IPv6 Unique Local Address is an IPv6 address in the block FC00::/7. It is the approximate IPv6 counterpart of the IPv4 private address. It is not routable on the global Internet.
Note: In the past, Site-local addresses (FEC0::/10) are equivalent to private IP addresses in IPv4 but now they are deprecated.
Link-local addresses only used for communications within the local subnet. It is usually created dynamically using a link-local prefix of FE80::/10 and a 64-bit interface identifier (based on 48-bit MAC address).

QUESTION: 18

Which IPv6 address block sends packets to a group address rather than a single address?

2000::/3
FC00::/7
FE80::/10
FF00::/8

Answer(s): D

Explanation:

FF00::/8 is used for IPv6 multicast and this is the IPv6 type of address the question wants to ask.
FE80::/10 range is used for link-local addresses. Link-local addresses only used for communications within the local subnetwork (automatic address configuration, neighbor discovery, router discovery, and by many routing protocols). It is only valid on the current subnet. It is usually created dynamically using a link-local prefix of FE80::/10 and a 64-bit interface identifier (based on 48-bit MAC address).

QUESTION: 19

What are two reasons that cause late collisions to increment on an Ethernet interface? (Choose two.)

when Carrier Sense Multiple Access/Collision Detection is used
when one side of the connection is configured for half-duplex
when the sending device waits 15 seconds before sending the frame again
when a collision occurs after the 32nd byte of a frame has been transmitted
when the cable length limits are exceeded

Answer(s): B,E

Explanation:

A late collision is defined as any collision that occurs after the first 512 bits (or 64th byte) of the frame have been transmitted. The usual possible causes are full- duplex/half-duplex mismatch, exceeded Ethernet cable length limits, or defective hardware such as incorrect cabling, non-compliant number of hubs in the network, or a bad NIC.
Late collisions should never occur in a properly designed Ethernet network. They usually occur when Ethernet cables are too long or when there are too many repeaters in the network.
