NEW QUESTION NO: 6
A network device that associates a Media Access Control (MAC) address with a port is a:
A. DSL modem
B. Hub
C. Router
D. Switch
Answer: D
Explanation/Reference:
A switch begins learning the local MAC addresses as soon as it is connected to other devices or to a network. This learning capability makes switches easy to use on a network.
The switch learning process works like this:
1.As a PC or other networked device sends a frame to another device through the switch, the switch captures the source MAC address of the frame and the interface that received it.
2.The switch confirms or adds the MAC address and the port to the lookup table.

NEW QUESTION NO: 7
One purpose of a perimeter network is to:
A. Make resources available to the intranet.
B. Link campus area networks (CANs).
C. Link local area networks (LANs).
D. Make resources available to the Internet.
Answer: D
Explanation/Reference:
In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external network node only has direct access to equipment in the DMZ, rather than any other part of the network.

NEW QUESTION NO: 8
One reason to replace an unmanaged switch with a managed switch is to:
A. Manage the routing tables.
B. Support multiple VLANS.
C. Reduce collision domains.
D. Route between networks,
Answer: B
Explanation/Reference:
A multilayer switch (MLS) is a computer networking device that switches on OSI layer 2 like an ordinary network switch and provides extra functions on higher OSI layers.
The major difference between the packet switching operation of a router and that of a Layer 3 switch is the physical implementation. In general-purpose routers, packet switching takes place using software that runs on a microprocessor, whereas a Layer 3 switch performs this using dedicated application-specific integrated circuit (ASIC) hardware.

NEW QUESTION NO: 9
The service that resolves fully qualified domain names (FQDN) to IP addresses is:
A. Windows Internet Name Service (WINS).
B. Domain Name Service (DNS).
C. Internet Service Provider (ISP).
D. Address Resolution Protocol (ARP).
Answer: B
Explanation/Reference:
The DNS translates Internet domain and host names to IP addresses. DNS automatically converts the names we type in our Web browser address bar to the IP addresses of Web servers hosting those sites.

NEW QUESTION NO: 11
This question requires that you evaluate the underlined text to determine if it is correct.
All session data is "encrypted between all machines" while using telnet.
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. Not encrypted
B. Encrypted between any Windows machines
C. Encrypted only to any non-Windows machines
D. No change is needed
Answer: A
Explanation/Reference:
Telnet, by default, does not encrypt any data sent over the connection (including passwords), and so it is often practical to eavesdrop on the communications and use the password later for malicious purposes; anybody who has access to a router, switch, hub or gateway located on the network between the two hosts where Telnet is being used can intercept the packets passing by and obtain login, password and whatever else is typed with a packet analyzer.

NEW QUESTION NO: 12
Which type of port is used to support VLAN traffic between two switches?
A. Virtual port
B. WAN port
C. Trunk port
D. LAN port
Answer: C
Explanation/Reference:
Trunk links are required to pass VLAN information between switches.

NEW QUESTION NO: 13
At what layer in the OSI model are hardware addresses referenced?
A. Physical
B. Application
C. Data link
D. Network
Answer: C

NEW QUESTION NO: 14
A cable that meets the l000BaseT standard has a maximum length of:
A. 100 m
B. 250 m
C. 500 m
D. 1,000 m
Answer: A
Explanation/Reference:
When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is 100 meters or 328 feet.

NEW QUESTION NO: 15
To directly connect the Ethernet network interface cards (NICs) of two computers, you should use a:
A. Crossover cable
B. Straight cable
C. Rollover cable
D. Coaxial cable
Answer: A
Explanation/Reference:
An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly. Normal straight through cables were used to connect from a host network interface controller (a computer or similar device) to a network switch, hub or router.

NEW QUESTION NO: 16
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/Reference:
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.
