Which three addresses are valid public addresses? (Choose three.) 198.133.219.17 192.168.1.245 10.15.250.5 128.107.12.117 192.15.301.240 64.104.78.227

198.133.219.17 128.107.12.117 64.104.78.227

How many hosts are addressable on a network that has a mask of 255.255.255.248? 2 6 8 14 16 254

Refer to the exhibit. An administrator is testing connectivity to a remote device with the IP address 10.1.1.1. What does the output of this command indicate? Connectivity to the remote device was successful. A router along the path did not have a route to the destination. A ping packet is being blocked by a security device along the path. The connection timed out while waiting for a reply from the remote device.

A router along the path did not have a route to the destination.

Refer to the exhibit. 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. The connectivity between these two hosts allows for videoconferencing calls. 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. This host does not have a default gateway configured.

There is connectivity between this device and the device at 192.168.100.1. There are 4 hops between this device and the device at 192.168.100.1.

Which three statements characterize UDP? (Choose three.) UDP provides basic connectionless transport layer functions. UDP provides connection-oriented, fast transport of data at Layer 3. UDP relies on application layer protocols for error detection. UDP is a low overhead protocol that does not provide sequencing or flow control mechanisms. UDP relies on IP for error detection and recovery. UDP provides sophisticated flow control mechanisms.

Which two roles can a computer assume in a peer-to-peer network where a file is being shared between two computers? (Choose two.) client master server slave transient

client server

Refer to the exhibit. The network administrator for a small advertising company has chosen to use the 192.168.5.96/27 network for internal LAN addressing. As shown in the exhibit, a static IP address is assigned to the company web server. However, the web server cannot access the Internet. The administrator verifies that local workstations with IP addresses that are assigned by a DHCP server can access the Internet, and the web server is able to ping local workstations. Which component is incorrectly configured? subnet mask DNS address host IP address default gateway address

default gateway address

What important information is added to the TCP/IP transport layer header to ensure communication and connectivity with a remote network device? timing and synchronization destination and source port numbers destination and source physical addresses destination and source logical network addresses

destination and source port numbers

What are two examples of the cut-through switching method? (Choose two.) store-and-forward switching fast-forward switching CRC switching fragment-free switching QOS switching

fast-forward switching fragment-free switching

What type of IPv6 address is FE80::1? loopback link-local multicast global unicast

link-local

When planning for network growth, where in the network should packet captures take place to assess network traffic? on as many different network segments as possible only at the edge of the network between hosts and the default gateway only on the busiest network segment

on as many different network segments as possible

What is the TCP mechanism used in congestion avoidance? three-way handshake socket pair two-way handshake sliding window

sliding window

What information is added during encapsulation at OSI Layer 3? source and destination MAC source and destination application protocol source and destination port number source and destination IP address

source and destination IP address

Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask? to identify the broadcast address of the destination network to identify the host address of the destination host to identify faulty frames to identify the network address of the destination network

to identify the network address of the destination network

What is the function of the HTTP GET message? to request an HTML page from a web server to send error information from a web server to a web client to upload content to a web server from a web client to retrieve client email from an email server using TCP port 110

to request an HTML page from a web server

What are two actions performed by a Cisco switch? (Choose two.) building a routing table that is based on the first IP address in the frame header using the source MAC addresses of frames to build and maintain a MAC address table forwarding frames with unknown destination IP addresses to the default gateway utilizing the MAC address table to forward frames via the destination MAC address examining the destination MAC address to add new entries to the MAC address table

using the source MAC addresses of frames to build and maintain a MAC address table utilizing the MAC address table to forward frames via the destination MAC address

In what two situations would UDP be the preferred transport protocol over TCP? (Choose two.) when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated when a faster delivery mechanism is needed when delivery overhead is not an issue when applications do not need to guarantee delivery of the data when destination port numbers are dynamic

when a faster delivery mechanism is needed when applications do not need to guarantee delivery of the data
