Which value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?
Differentiated Services
Fragment Offset
Header Length
Time-to-Live
Which two statements describe features of an IPv4 routing table on a router? (Choose two.)
Directly connected interfaces will have two route source codes in the routing table: C and S .
The netstat -r command can be used to display the routing table of a router.
If there are two or more possible routes to the same destination, the route associated with the higher metric value is included in the routing table
If a default static route is configured in the router, an entry will be included in the routing table with source code S .
Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types?
financial transactions, web page, audio conference
financial transactions, audio conference, web page
audio conference, financial transactions, web page
audio conference, web page, financial transactions
What is the consequence of configuring a router with the ipv6 unicast-routing global configuration command?
All router interfaces will be automatically activated.
Each router interface will generate an IPv6 link-local address
The IPv6 enabled router interfaces begin sending ICMPv6 Router Advertisement messages.
It statically creates a global unicast address on this router.
Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?
application, transport, Internet, and network access layers
only application and Internet layers
only Internet and network access layers
application, session, transport, network, data link, and physical layers
The global configuration command ip default-gateway 172.16.100.1 is applied to a switch. What is the effect of this command?
The switch can communicate with other hosts on the 172.16.100.0 network.
The switch can be remotely managed from a host on another network.
The switch will have a management interface with the address 172.16.100.1
The switch is limited to sending and receiving frames to and from the gateway 172.16.100.1
What characteristic describes adware?
a network device that filters access and traffic coming into a network
an attack that slows or crashes a device or network service
the use of stolen credentials to access private data
software that is installed on a user device and collects information about the user
What is the purpose of the TCP sliding window?
to ensure that segments arrive in order at the destination
to request that a source decrease the rate at which it transmits data
to inform a source to retransmit data from a specific point forward
to end communication when data transmission is complete
What technique is used with UTP cable to help protect against signal interference from crosstalk?
terminating the cable with special grounded connectors
twisting the wires together into pairs
wrapping a foil shield around the wire pairs
encasing the cables within a flexible plastic sheath
A network technician is researching the use of fiber optic cabling in a new technology center. Which two issues should be considered before implementing fiber optic media? (Choose two.)
Fiber optic cabling requires different termination and splicing expertise from what copper cabling requires.
Fiber optic cabling requires specific grounding to be immune to EMI.
Fiber optic provides higher data capacity but is more expensive than copper cabling.
Fiber optic cable is able to withstand rough handling.
Fiber optic cabling is susceptible to loss of signal due to RFI
Users are reporting longer delays in authentication and in accessing network resources during certain time periods of the week. What kind of information should network engineers check to find out if this situation is part of a normal network behavior?
syslog records and messages
debug output and packet captures
the network performance baseline
network configuration files
A user is complaining that an external web page is taking longer than normal to load.The web page does eventually load on the user machine. Which tool should the technician use with administrator privileges in order to locate where the issue is in the network?
ipconfig /displaydns
nslookup
tracert
ping
A client packet is received by a server. The packet has a destination port number of 53. What service is the client requesting?
SSH
FTP
TELNET
DNS
An IPv6 enabled device sends a data packet with the destination address of FF02::2. What is the target of this packet?
all IPv6 configured routers on the local link
all IPv6 enabled devices across the network
all IPv6 DHCP servers
all IPv6 enabled devices on the local link
What are the three parts of an IPv6 global unicast address? (Choose three.)
subnet ID
global routing prefix
subnet mask
interface ID
broadcast address
What is one main characteristic of the data link layer?
It generates the electrical or optical signals that represent the 1 and 0 on the media.
It converts a stream of data bits into a predefined code.
It shields the upper layer protocol from being aware of the physical medium to be used in the communication.
It accepts Layer 3 packets and decides the path by which to forward the packet to a remote network.
Which type of security threat would be responsible if a spreadsheet add-on disables the local software firewall?
Trojan horse
brute-force attack
DoS
buffer overflow
What service is provided by HTTPS?
Uses encryption to secure the exchange of text, graphic images, sound, and video on the web
Resolves domain names, such as cisco.com, into IP addresses.
Uses encryption to provide secure remote access to network devices and servers.
Allows remote access to network devices and servers.
Refer to the exhibit. If host A sends an IP packet to host B, what will the destination address be in the frame when it leaves host A?
BB:BB:BB:BB:BB:BB
172.168.10.99
AA:AA:AA:AA:AA:AA
CC:CC:CC:CC:CC:CC
Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.)
Destination MAC addresses will never change in a frame that goes across seven routers.
A packet that has crossed four routers has changed the destination IP address four times.
Destination and source MAC addresses have local significance and change every time a frame goes from one LAN to another.
Destination IP addresses in a packet header remain constant along the entire path to a target host.
