. Which of the following provides a connectionless
transport service?
- UDP
Explanation:
- Protocols such as IPX, IP and UDP are considered to be
- connectionless. They place the packet on the network and assume the address
- will get it through. This is similar to the U.S. Mail system. When the
- connectionless protocol is used, packet sequencing and sorting are handled at
- higher levels. This allows faster delivery. Packets in connectionless service
- are called datagrams.
-

- B - ranges from 128 to 191\nClass C - ranges from 192 to 223\n
-
Which WI-Fi security protocol provides better
protection?
- WPA

-
Which of the following protocols is responsible for
converting the hardware address 00-4A-2B-E9-AF-37 to an IP address?
RARP
Explanation:
- When IP has a datagram to send, it has already been
- informed by upper-layer protocols of the destination's address. However, IP
- must also inform a Network Access protocol such as Ethernet or Token Ring, of
- the destination's hardware address. If IP doesn't know the hardware address, it
- uses the ARP protocol to find this information.
-
An Ipv6 address for which uniqueness has been verified
and from which unicast traffic can be sent and received is classified as which
of the following?
- Valid
Explanation:
- A Valid address is
- an address for which uniqueness has been verified and from which unicast
- traffic can be sent and received. The valid state covers both the preferred and
- deprecated states.
-
A protocol used to map an IP address to a physical MAC
address is:
- Remember, when IP has a datagram to send, it has already
- been informed by upper-layer protocols of the destination's address. However,
- IP must also inform a Network Access protocol such as Ethernet or Token Ring,
- of the destination's hardware address. If IP doesn't know the hardware address,
- it uses the ARP protocol to find this information.
-
Which of the following are connectionless protocols?
(Choose two)
- TFTP
- UDP
Explanation:
Remember, TFTP and UDP are connectionless, opting for speed over guaranteed delivery.
-
255.255.255.0 is the subnet mask for which class of IP
network?
- C
Explanation:
- The default subnet masks for Class A, B and C networks
- are: \nClass A - 255.0.0.0\nClass B - 255.255.0.0\nClass C - 255.255.255.0\n
-
Of the IEEE specifications listed, which is (are) capable
of operating at 11Mbps? (choose all that apply)
- 802.11b
- 802.11a
- 802.11g
Explanation:
- The highest speed an 802.11b can reach is 11Mbps. 802.11a
- and 802.11g devices, while capable of higher speeds, will also communicate at
- lower speeds.
-
. Which of the following represents a mac
address?
- 00-E0-29-27-37-46
Explanation:
- MAC address are factory assigned hardware that are burned
- into your device's ROM. They are hexidecimal numbers containing values from 0-9
- and A-F. You may find these values separated by dashes or colons.
-
Which routing method requires more administrative
overhead?
- Static
Explanation:
- Remember, with static routing you must manually enter the
- address information as well as any changes.
-
In an E-mail system, which of the following is the
