ICMP IP
Which communication tool allows real-time collaboration?
Instant messaging.
What is an important function of the physical layer of the OSI model?
It encodes frames into electrical, optical, or radio wave signals.
Refer to the exhibit. Consider the IP address configuration shown from PC1. What is a description of the default gateway address?
It is the IP address of the Router1 interface that connects the PC1 LAN to Router1.
Which address on a PC does not change, even if the PC is moved to a different network?
MAC address
Which publicly available resources describe protocols, processes, and technologies for the Internet but do not give implementation details?
MAC address
Which technology provides a solution to IPv4 address depletion by allowing multiple devices to share one public IP address?
NAT
In which default order will a router search for startup configuration information?
NVRAM, TFTP, setup mode
Refer to the exhibit. Which action will be successful?
PC2 can send a ping to 192.168.1.1.
Which of the following are primary functions of a router? (Choose two.)
Packet switching Path selection
What is a function of the data link layer?
Provides for the exchange of data over a common local media.
Which two statements correctly describe a router memory type and its contents? (Choose two.)
ROM is nonvolatile and contains basic diagnostic software. & RAM is volatile and stores the IP routing table.
Refer to the exhibit. Which IP addressing scheme should be changed?
Site 2
Refer to the exhibit. An administrator is trying to configure the switch but receives the error message that is displayed in the exhibit. What is the problem?
The administrator must first enter privileged EXEC mode before issuing the command.
Refer to the exhibit. A technician has configured a user workstation with the IP address and default subnet masks that are shown. Although the user can access all local LAN resources, the user cannot access any Internet sites by using either FQDN or IP addresses. Based upon the exhibit, what could account for this failure?
The default gateway address in incorrect.
What will happen if the default gateway address is incorrectly configured on a host?
The host cannot communicate with hosts in other networks
What happens when part of an Internet VoIP transmission is not delivered to the destination?
The transmission continues without the missing portion.
What is the effect of configuring the ipv6 unicast-routing command on a router?
To enable the router as an IPv6 router
What is the purpose of ICMP messages?
To provide feedback of IP packet transmissions
