Incorrect:

not cat5: Max speed is 100Mbps

not Cat6: 20% higher cost than Cat 5e.

When a zone that this DNS server hosts is a primary zone, the DNS server is the primary source for information about this zone, and it stores the master copy of zone data in a local file or in AD DS.

Incorrect:

The private address space specified in RFC 1918 is defined by the following three address blocks:

not A: 192.168.0.0/16 The 192.168.0.0/16 private network can be interpreted either as a block of 256 class C network IDs or as a 16-bit assignable address space (16 host bits) that can be used for any subnetting scheme within the private organization. The 192.168.0.0/16 private network allows the following range of valid IP addresses: 192.168.0.1 to 192.168.255.254.

Not C:

10.0.0.0/8 The 10.0.0.0/8 private network is a class A network ID that allows the following range of valid IP addresses: 10.0.0.1 to 10.255.255.254. The 10.0.0.0/8 private network has 24 host bits that can be used for any subnetting scheme within the private organization.

Not D:

172.16.0.0/12 The 172.16.0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any subnetting scheme within the private organization. The 172.16.0.0/12 private network allows the following range of valid IP addresses: 172.16.0.1 to 172.31.255.254.

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.

IEEE 802.11n-2009, commonly shortened to 802.11n, is a wireless networking standard that uses multiple antennas to increase data rates.

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address (MAC address) that is recognized in the local network.

DNS is not working.

Layer 2 switching uses the media access control address (MAC address) from the host's network interface cards (NICs) to decide where to forward frames.

Insecure Wi-Fi is the easiest way for people to access your home network, leech your internet, and cause you serious headaches with more malicious behavior.

The majority of NATs map multiple private hosts to one publicly exposed IP address. In a typical configuration, a local network uses one of the designated "private" IP address subnets (RFC 1918). A router on that network has a private address in that address space. The router is also connected to the Internet with a "public" address assigned by an Internet service provider.

Media contention occurs when two or more network devices have data to send at the same time. Because multiple devices cannot talk on the network simultaneously, some type of method must be used to allow one device access to the network media at a time. This is done in two main ways: carrier sense multiple access collision detect (CSMA/CD) and token passing.

The start of authority (SOA) resource record indicates the name of origin for the zone and contains the name of the server that is the primary source for information about the zone. It also indicates other basic properties of the zone.

* Yes.

QoS traffic control: Regulate data flows by classifying, scheduling, and marking packets based on priority and by shaping traffic (smoothing bursts of traffic by limiting the rate of flow). Traffic control mechanisms segregate traffic into service classes and control delivery to the network. The service class assigned to a traffic flow determines the QoS treatment the traffic receives.

* Yes.

The goal of QoS is to provide preferential delivery service for the applications that need it by ensuring sufficient bandwidth, controlling latency and jitter, and reducing data loss.

* No

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.

A single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a virtual local area network, virtual LAN or VLAN.

LANs are layer 2 constructs, so they can be supported by both Layer 2 and Layer 3 switches.

Incorrect:

Not A: Layer 2 switches do not provide high level of security.

Not B: Another name for logical address is IP address. Only Layer 3 switches uses IP address. Layer 2 switches uses MAC addresses.

Not C: only Layer 3 switches forward packets on the network (like routers).

A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet.

802.1x

This deployment scenario requires server certificates for each NPS server that performs 802.1X authentication.

SSL or TLS encryption takes place at the presentation layer, Layer 6 of the OSI model.

* UDP uses a simple connectionless transmission model with a minimum of protocol mechanism. User datagram protocol (UDP) provides a thinner abstraction layer which only error-checks the datagrams.

Note: Best-effort delivery describes a network service in which the network does not provide any guarantees that data is delivered or that a user is given a guaranteed quality of service level or a certain priority.

* Transmission control protocol (TCP) provides a guaranteed delivery of an octet stream between a pair of hosts to the above layer, internally splitting the stream into packets and resending these when lost or corrupted.

* Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address (MAC address) that is recognized in the local network.

802.11g hardware is fully backward compatible with 802.11b hardware.

In local area networks with a star topology, each network host is connected to a central hub with a point-to-point connection.

WPA aims to provide stronger wireless data encryption than WEP.

Wi-Fi Protected Access (WPA) is a security protocol and security certification program developed by the Wi-Fi Alliance to secure wireless computer networks.

169.254.1.15 is an APIPA address. An APIPA address is used when the DHCP server is not available.

The speed of a Wi-Fi wireless network connection depends on several factors.

Like most kinds of computer networks, Wi-Fi supports varying levels of performance depending on which technology standards it supports. Each Wi-Fi standard is rated according to its maximum theoretical network bandwidth:

A Wi-Fi network connection operates at the highest possible speed that both devices (endpoints) can support. An 802.11g laptop connected to an 802.11n router, for example, will network at the lower speeds of 'g'.
