What is the device filters data traffic at a network boundary?
The device that filters data traffic at a network boundary is commonly known as a firewall. Firewalls monitor incoming and outgoing network traffic and enforce security policies by allowing or blocking specific data packets based on predetermined rules. They can be hardware-based, software-based, or a combination of both, and are essential for protecting networks from unauthorized access and cyber threats.
Does a firewall encrypt data?
No, it filters traffic based on certain set rules.
Which device makes traffic forwarding decisions based on mac address?
A switch uses MAC address to forward frames while a router uses IP addresses.
What is ACL stands for in networking configuration?
ACL stands for Access Control List. ACLs are used in networking to control which types of traffic are allowed to pass through a network device, such as a router or firewall. They can be configured to permit or deny traffic based on criteria such as source IP address, destination IP address, protocol, and port number.
Which two packet filters could a network administrator use on an IPv4 extended ACL?
A network administrator can use the source IP address and destination IP address as packet filters in an IPv4 extended ACL. Additionally, they can filter based on protocols such as TCP or UDP and specify port numbers to further refine access control. This allows for precise control over the traffic allowed or denied through the network.
Which security device is used to monitor network traffic for illegal activities based on known attack-signatures?
NIDS
How can I use a GPS device or app to map my travel route efficiently and accurately?
To use a GPS device or app to map your travel route efficiently and accurately, first input your destination address or coordinates. The GPS will calculate the best route based on real-time traffic data. Follow the directions provided, and adjust your route as needed if there are any road closures or traffic delays. Make sure to keep your GPS device or app updated for the most accurate information.
How many bits does an eui-64 address have?
An EUI-64 address has 64 bits. It is commonly used in IPv6 for automatically generating interface identifiers based on the MAC address of a device. The EUI-64 format allows for the inclusion of the device's 48-bit MAC address, which is expanded to fit the 64-bit requirement.
Which network device makes forwarding decisions based on the destination MAC address that is contained in the frame?
Switches and Bridges
Is a device that manages traffic between two networks?
Most of the time you use a router between two networks. You can also use a bridge but bridges are most likely software based. Routers are hardware based or "appliances".
Filters decide whether to allow or block packets based on information in the protocol headers?
Stateless Packet Filters
What device is used to protect one network from another by using filtering packets?
A firewall is the device used to protect one network from another by filtering packets. It monitors and controls incoming and outgoing network traffic based on predetermined security rules. Firewalls can be hardware-based, software-based, or a combination of both, and they help prevent unauthorized access and attacks on a network.
