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

Refer to the exhibit. The IP address of which device interface should be used as the default gateway setting of host H1?

• • R2: S0/0/1

• • R1: G0/0

• • R2: S0/0/0

• • R1: S0/0/0

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
