Question 1: three primary functions provided by Layer 2 data encapsulation

Answer:

data link layer addressing detection of errors through CRC calc delimiting groups of bits into frames

Question 2: interface VLAN1

Answer:

Cisco IOS Layer 2 switches have physical ports for devices to connect. These ports do not support Layer 3 IP addresses. Therefore, switches have one or more switch virtual interfaces (SVIs). These are virtual interfaces because there is no physical hardware on the device associated with it. An SVI is created in software.The virtual interface provides a means to remotely manage a switch over a network using IPv4. Each switch comes with one SVI appearing in the default configuration "out-of-the-box." The default SVI is interface VLAN1.Question 3: NIC has responsibilities in both layer 1 and 2 - purpose of the physical layer

Answer:

factors that cause throughput mismatch the specified bandwidth of physical links

Question 4: *a single packet can be sent to a group of hosts

*multicast transmissions can be used by routers to exchange routing information *routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255

Answer:

three ranges of IP address that are reserved for internal private use

Question 5: addresses mapped by ARP

Answer:

services provided by the OSI network layer Question 6: TCP and UDP overview - port number is used as the destination port number

Answer:

two ways that the TCP uses the sequence numbers in a segment

Question 7: VLSM

Answer:

The use of the source and destination port numbers

Question 8: 255.255.255.128

Answer:

is 192.168.1.61/26 the subnet to include 192.168.1.96

Question 9: function of the shell in an OS

Answer:

to act as an intermediary between user and OS through GUI or CLI

Question 10: dotted decimal representation of the IPv4 address

Answer:

three characteristics of multicast transmission

Question 11: assists in protocol design

prevents technology in one layer from affecting other layers

Answer:

OSI model Vs TCP/IP Model layers

Question 12: DHCP protocol, CSMA/CD, ICMP, SNMP, and FTP

Answer:

A trojan horse, viruses and worm features

Question 13: modes of operation

Answer:

User EXEC Mode ">" This mode has limited capabilities but is useful for basic operations. It allows only a limited number of basic monitoring commands but does not allow the execution of any commands that might change the configuration of the device. The user EXEC mode is identified by the CLI prompt that ends with the > symbol.Privileged EXEC Mode "#" To execute configuration commands, a network administrator must access privileged EXEC mode. Higher configuration modes, like global configuration mode, can only be reached from privileged EXEC mode. The privileged EXEC mode can be identified by the prompt ending with the # symbol.

Question 14: name of the transport layer PDU

Answer:

segment

Question 15: characteristics of fault tolerant network

Answer:

Redundancy

Question 16: characteristic of of LLC sublayer

Answer:

characteristic of fiber-optic cable

Question 17: retain contents when power is removed

store the startup configuration file

Answer:

configure initial settings Question 18: provides high availability and connects some, but not all, remote sites

Answer:

LAN topologies - carrier sense multiple access with collision avoidance (CSMA/CA)

Question 19: range of link-local addresses

Answer:

FE80::1/10

Question 20: encourages competition and promotes choices

Answer:

benefits of layered model

Question 21: Nslookup, traceroute, ipconfig, and netstat utilities

Answer:

top-level domains

Question 22: not affected by EMI or RFI

more expensive than UTP

Answer:

WAN topologies - partial mesh topologies

Question 23: converts ipv6 to ipv4

Answer:

most compressed format IPv6 Question 24: number of valid host addresses on an IPv4 subnet that is configured with a /26 mask

Answer:

subnet mask for the site must accommodate 126 hosts Question 25: TCP - Layer 4 protocol, responsibilities in the network communication process

Answer:

advantages of open protocol

Question 26: Ctrl-Shft-6 key command

Answer:

All purpose break sequence. used to abort DNS lookups, traceroutes and pings.
