A network administrator is using an application that is monitoring packets on the network and sees an EIGRP update packet What is the purpose of the update packet?
bobo
The packet is sent to discover neighbors within the EIGRP network.
The packet is sent to search for network devices within an EIGRP network.
The packet is used to propagate routing information within the EIGRP network.
The packet is used to send an unreachable reply to another router within the EIGRP network.
What else can I help you with?
The administrator would identify which address as the address to which all hosts send packets that are destined for an outside network?
10.10.10.6
A network administrator needs to restrict access to the network Which type of firewall allows only those packets that are part of a known connection?
The firewall that only allows packets of registered connection is called packet filter. It is also the central piece in firewalling.
Which layer of the OSI model is concerned with end-to-end message delivery over the network?
transport layer of osi model is responsible for end to end delivery of packets over a network
How do you calculate packet delivery ratio in MANET?
I think PDR= Packets Received / Packets Sent Packets sent/received values should be from same layer. i.e. all from application layer or network layer...etc
Does a firewall block ICMP packets?
A firewall can be configured to block ICMP packets, but it depends on the specific rules set by the network administrator. By default, many firewalls allow ICMP traffic for essential functions like ping and network diagnostics. However, to enhance security, some firewalls may restrict or block certain types of ICMP packets to prevent potential attacks or network scanning. Ultimately, whether ICMP packets are blocked or allowed is determined by the firewall's configuration.
Data is transmitted on a network in pieces called?
Packets Words
What is used to duplicate all traffic on one port in a switch to another switch port?
To duplicate all traffic on one port to another port in a switch, a feature called "port mirroring" or "SPAN" (Switched Port Analyzer) is used. This feature allows the network administrator to configure the switch to send a copy of all the packets from a specified port or VLAN to another designated port for monitoring or analysis. It is commonly used for network monitoring, troubleshooting, and performance analysis.
What does a sniffer program do?
A packet sniffer uses a network connection in promiscuous mode to receive and record packets that were not intended for that computer. This can be used by a network administrator to monitor a network and find potential security problems. It can also be used by a hacker to access privileged information that is sent un-encrypted through the network.
Can a network administrator view the internet history of the clients of a wireless network through the router?
yes, i use a program called wireshark. it's a packet analyzer that tracks every packet sent through a router/hub. you just have to apply the right filters to narrow down the packets. technically this isn't "history", but while this program is running, all packets sent through the network are recorded.
How can a Linux system administrator verify that the Linux system is forwaring IPV4 packets?
A Linux system administrator can verify that the Linux system is forwaring IPV4 packets by querying the sysctl kernel to see if forwarding is enabled.
Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?
tunneling
What is EtherPeek is used for?
EtherPeek is a network protocol analyzer tool commonly used for troubleshooting and analyzing network traffic. It provides real-time monitoring of network packets to detect issues such as network congestion, errors, and security breaches. EtherPeek is widely used by network administrators and IT professionals to diagnose and resolve network-related problems.
