Question 1
DRAG DROP
Match the OSI layer to its corresponding description.
To answer, drag the appropriate OSI layer from the column on the left to its description on the right. Each OSI layer may be
used once, more than once, or not at all. Each correct match is worth one point.
Select and Place:
Answer:
Explanation:
* (1) Application layer protocols include:
Remote login to hosts: Telnet
File transfer: File Transfer Protocol (FTP), Trivial File Transfer Protocol (TFTP)
Electronic mail transport: Simple Mail Transfer Protocol (SMTP)
NTP, Network Time Protocol * (2) Session Layer
Session-layer services are commonly used in application environments that make use of remote procedure calls (RPCs).
NetBios is also a session layer protocol. * (3) Network Layer
The network layer is responsible for packet forwarding including routing through intermediate routers. Network Layer
protocols include IPX (Internetwork Packet Exchange).
/ X.25 is one of the oldest packet-switched services available. It was developed before the OSI Reference Model. The
protocol suite is designed as three conceptual layers, which correspond closely to the lower three layers of the seven-layer
OSI model. It also supports functionality not found in the OSI network layer.
/ NetWare Link Services Protocol (NLSP) is a routing protocol for Internetwork Packet Exchange (IPX).
* (4) Data link layer
WAPs (Wireless access points) and wwitches operate on the data link layer.
* (5) Network layer
Network layer protocols include ICMP (Internet Control Message Protocol), RIP (Routing Information Protocol), and ARP
(Address Resolution Protocol).
* (6) Data link layerthe data link layer is responsible for media access control, flow control and error checking. Bridges and
network cards are on the data link layer.
Question 2
What is the minimum cabling requirement for a 100BaseTX network?
- A. Category 3 UTP cable
- B. Category 5 UTP cable
- C. Category 6 UTP cable
- D. Multimode fiber cable
Answer:
B
Explanation:
100BASE-TX is the predominant form of Fast Ethernet, and runs over two wire-pairs inside a category 5 or above cable.
100BASE-TX and 1000BASE-T were both designed to require a minimum of Category 5 cable and also specify a maximum
cable length of 100 meters. Category 5 cable has since been deprecated and new installations use Category 5e.
Question 3
Which two are published IEEE 802.11 wireless transmission standards? (Choose two.)
- A. 802.1 If
- B. 802.11g
- C. 802.11k
- D. 802.11m
- E. 802.11n
Answer:
B E
Explanation:
The 802.11 family consists of a series of half-duplex over-the-air modulation techniques that use the same basic protocol.
802.11-1997 was the first wireless networking standard in the family, but 802.11b was the first widely accepted one, followed
by 802.11a, 802.11g, 802.11n, and 802.11ac.
Question 4
HOTSPOT
For each of the following statements, select Yes if the statement is true. Otherwise, select No. Each correct selection is
worth one point.
Hot Area:
Answer:
Explanation:
* The localhost (loopback) address, 0:0:0:0:0:0:0:1, and the IPv6 unspecified address, 0:0:0:0:0:0:0:0, are reduced to ::1 and
::, respectively.
* A unique local address (ULA) is an IPv6 address in the block fc00::/7, defined in RFC 4193. It is the approximate IPv6
counterpart of the IPv4 private address.
* Link-local addresses for IPv4 are defined in the address block 169.254.0.0/16, in CIDR notation. In IPv6, they are assigned
with the fe80::/10 prefix.

The level of security set for the Local intranet zone is applied to websites and content that is stored on a corporate or
business network. Reference: Change Internet Explorer Security settings
Question 8

For each of the following statements, select Yes if the statement is true. Otherwise, select No. Each correct selection is
worth one point.
Hot Area:
Answer:
Explanation:
Sometimes you will want to create a tunnel without encryption. The IPSEC protocols provide two ways to do this
Question 9
This question requires that you evaluate the underlined text to determine if it is correct.
The 802.11n wireless standard specifies a maximum data rate of 54 Mbps.
Review the underlined text. If it makes the statement correct, select No change is needed. If the statement is incorrect,
select the answer choice that makes the statement correct.
- A. 10 Mbps
- B. 11-128 Mbps
- C. 300-600 Mbps

Answer:
C
Question 10
Which of the following uses a tunneling protocol?
- A. Internet
- B. VPN
- C. Extranet
- D. VLAN
Answer:
B
Explanation:
Tunneling enables the encapsulation of a packet from one type of protocol within the datagram of a different protocol. For
example, VPN uses PPTP to encapsulate IP packets over a public network, such as the Internet.
Question 11
This question requires that you evaluate the underlined text to determine if it is correct.
The four IEEE standards, 802.11a, b, g, and n, are collectively known as "mobile ad hoc" networks.
Select the correct answer if the underlined text does not make the statement correct. Select 'No change is needed" if the
underlined text makes the statement correct.
- A. WiMAX
- B. Bluetooth
- C. WiFi
- D. No change is needed
Answer:
C
Explanation:
IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local
area network (WLAN) computer communication in the 2.4, 3.6, 5, and 60 GHz frequency bands. They are created and
maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in
1997, and has had subsequent amendments. The standard and amendments provide the basis for wireless network
products using the Wi-Fi brand.
