transport layer error check field
User Datagram Protocol field
flow control field
frame check sequence field
2
What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.)
MAC addresses
IP addresses
Layer 1 statuses
next-hop addresses
3
Refer to the exhibit. What is wrong with the displayed termination?
The wires are too thick for the connector that is used
The wrong type of connector is being used.
The woven copper braid should not have been removed.
The untwisted length of each wire is too long.
4
To which switching method will the switch revert when the error threshold is reached?
fragment-free
cut-through
store-and-forward
fast-forward
5
On the basis of the output, which two statements about network connectivity are correct? (Choose two.)
There is connectivity between this device and the device at 192.168.100.1.
This host does not have a default gateway configured.
There are 4 hops between this device and the device at 192.168.100.1.
The average transmission time between the two hosts is 2 milliseconds.
6
Why would a Layer 2 switch need an IP address?
to enable the switch to receive frames from attached PCs
to enable the switch to be managed remotely
to enable the switch to send broadcast frames to attached PCs
to enable the switch to function as a default gateway
7
Which switching method drops frames that fail the FCS check?
borderless switching
cut-through switching
ingress port buffering
store-and-forward switching
8
What are proprietary protocols?
a collection of protocols known as the TCP/IP protocol suite
protocols developed by private organizations to operate on any vendor
protocols that can be freely used by any organization or vendor
protocols developed by organizations who have control over their operation
9
What are two common causes of signal degradation when using UTP cabling? (Choose two.)
low-quality cable or connectors
low-quality shielding in cable
loss of light over long distances
improper termination
10
What happens when the transport input ssh command is entered on the switch vty lines?
The switch requires a username/password combination for remote access.
The switch requires remote connections via a proprietary client software.
Communication between the switch and remote users is encrypted.
The SSH client on the switch is enabled.
11
What are two characteristics of IP? (Choose two.)
retransmits packets if errors occur
operates independently of the network media
guarantees delivery of packets
does not require a dedicated end-to-end connection
12
Which two issues should be considered before implementing fiber optic media? (Choose two.)
provides higher data capacity but is more expensive than copper cabling.
requires specific grounding to be immune to EMI
is susceptible to loss of signal due to RFI.
requires different termination and splicing expertise
13
The IP address of which device interface should be used as the default gateway setting of host H1?
R1: G0/0
R1: S0/0/0
R2: S0/0/1
R2: S0/0/0
14
What is an advantage to using a protocol that is defined by an open standard?
A company can monopolize the market.
It encourages competition and promotes choices.
The protocol can only be run on equipment from a specific vendor.
is not controlled or regulated by standards organizations
15
A printer is attached to a PC. Also is has been shared so that other PCs on network can also use it. What model is this
client-based
point-to-point
master-slave
peer-to-peer (P2P)
16
If host A sends an IP packet to host B, what will the destination address be in the frame when it leaves host A?
AA:AA:AA:AA:AA:AA
CC:CC:CC:CC:CC:CC
DD:DD:DD:DD:DD:DD
BB:BB:BB:BB:BB:BB
17
What are three commonly followed standards for constructing and installing cabling? (Choose three.)
cost per meter
cable lengths
connector types
pinouts
18
What is a function of the data link layer?
provides delivery of data between two applications
provides end-to-end delivery of data between hosts
provides the formatting of data
provides for the exchange of frames over a common local media
19
How does the service password-encryption command enhance password security on Cisco routers and switches?
It requires encrypted passwords to be used when connecting with telnet
It encrypts passwords that are stored in router/switch configuration files
It encrypts passwords as they are sent across the network
It requires that a user type encrypted passwords to gain console access
20
Which function is performed at the MAC sublayer of the Data Link Layer to facilitate Ethernet communication?
adds Ethernet control information to network protocol data
enables IPv4 and IPv6 to utilize the same physical medium
implements CSMA/CD over legacy shared half-duplex media
handles communication between upper layer software and Ethernet hardware
21
An admin is trying to configure the switch but receives this error message. What is the problem?
Admin must first enter privileged EXEC mode before issuing the command
The administrator is already in global configuration mode.
Admin must connect via the console port to access global configuration mode
The entire command, configure terminal , must be used.
22
Which 2 factors may interfere with the copper cabling and result in signal distortion and data corruption? (Choose two.)
crosstalk
RFI
signal attenuation
EMI
23
PC1 issues an ARP request because it needs to send a packet to PC2. In this scenario, what will happen next?
PC2 will send an ARP reply with its MAC address
SW1 will send an ARP reply with the PC2 MAC address.
RT1 will send an ARP reply with the PC2 MAC address.
RT1 will send an ARP reply with its Fa0/0 MAC address.
24
What attribute of a NIC would place it at the data link layer of the OSI model?
MAC address
RJ-45 port
IP address
TCP/IP protocol stack
25
Which information does the
show startup-config
command display?
the contents of the saved configuration file in the NVRAM
