A small-sized company has 30 workstations and 2 servers. The company has been assigned a group of IPv4 addresses 209.165.200.224/29 from its ISP.

port address translation
DHCP
static NAT

Which statement describes a stateful firewall?
It can determine if the connection is in the initiation, data transfer, or termination phase.
It can expand the number of IP addresses available and can hide network addressing design.
It can filter packets based on information at Layers 3, 4, 5 and 7 of the OSI reference model.
It can only filter packets based on limited Layer 3 and 4 information.
It can determine if the connection is in the initiation, data transfer, or termination phase.
Which impact does adding a Layer 2 switch have on a network?
an increase in the size of the broadcast domain
an increase in the size of the collision domain
an increase in the number of dropped frames
an increase in the number of network collisions
an increase in the size of the broadcast domain
Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)
UDP segments are encapsulated within IP packets for transport across the network.
The source port field identifies the running application or service that will handle data returning to the PC.
The TCP source port number identifies the sending host on the network.
TCP is the preferred protocol when a function requires lower network overhead.
The UDP destination port number identifies the application or service on the server which will handle the data.
The TCP process running on the PC randomly selects the destination port when establishing a session with the server.
UDP segments are encapsulated within IP packets for transport across the network.
The source port field identifies the running application or service that will handle data returning to the PC.
The UDP destination port number identifies the application or service on the server which will handle the data.
What is the function of the MIB element as part of a network management system?
to change configurations on SNMP agents
to collect data from SNMP agents
to store data about a device
to send and retrieve network management information
to store data about a device

A high school in New York (school A) is using videoconferencing technology to establish student interactions with another high school (school B) in Russia. The videoconferencing is conducted between two end devices through the Internet. The network administrator of school A configures the end device with the IP address 209.165.201.10. The administrator sends a request for the IP address for the end device in school B and the response is 192.168.25.10. Neither school is using a VPN. The administrator knows immediately that this IP will not work. Why?
There is an IP address conflict.
This is a loopback address.
This is a link-local address.
This is a private IP address.
This is a private IP address.
Which solution improves web response time by deploying multiple web servers and DNS servers?
memcaching
distributed databases
load balancing
sharding
load balancing
What command can a technician use on a computer to see if DNS is functioning properly?
net share
ipconfig
nslookup
net use
nslookup
What is the function of the Nslookup utility?
to display all cached DNS entries on a host
to manually query the name servers to resolve a given host name
to manually force a client to send a DHCP request
to view the network settings on a host
to manually query the name servers to resolve a given host name
A device has an IPv6 address listed as 2001:0DB8:75a3:0214:0607:1234:aa10:ba01. What is the interface ID of the device?

What will a host on an Ethernet network do if it receives a frame with a unicast destination MAC address that does not match its own MAC address?
It will strip off the data-link frame to check the destination IP address.
It will remove the frame from the media.
It will forward the frame to the next host.
It will discard the frame.
It will discard the frame.

What is one advantage of using the cut-through switching method instead of the store-and-forward switching method?
has a positive impact on bandwidth by dropping most of the invalid frames
has a lower latency appropriate for high-performance computing applications
makes a fast forwarding decision based on the source MAC address of the frame
provides the flexibility to support any mix of Ethernet speeds
has a lower latency appropriate for high-performance computing applications
