It describes how the network devices are actually interconnected with wires and cables. Physical topology Which of the following is NOT a characteristics of a network? All of the choices Stackable that are arranged one on top of the other with cables linking the switches in a _____________ connection. Daisy Chain To troubleshoot issues when a trunk is not forming or when VLAN leaking is occurring, what command to be used to check whether the local and peer native VLANs match? show interfaces trunk What type of DHCP attack where in an attacker floods the DHCP server with DHCP requests to use all the available IP addresses that the DHCP server can issue. After these IP addresses are issued, the server cannot issue any more addresses, and this situation produces a denial-of-service (DoS) attackas new clients cannot obtain network access. DHCP starvation attack This is a proprietary protocol that all Cisco devices can be configured to use. This checks other Cisco devices that are directly connected, which allows the devices to auto-configure their connection. Cisco Discovery Protocol In this attack, the attacker exploits a flaw in the Telnet server software running on the switch that renders the Telnet service unavailable. This sort of attack prevents an administrator from remotely accessing switch management functions.

This can be combined with other direct attacks on the network as part of a coordinated attempt to prevent the network administrator from accessing core devices during the breach. Telnet DoS attack Which of the following is the command to specify a VLAN name?

VLAN tagging This is a point-to-point link between two network devices that carries more than one VLAN Trunks What type of DHCP attack where in an attacker configures a fake DHCP server on the network to issue DHCP addresses to clients. The normal reason for this attack is to force the clients to use false Domain Name System (DNS) or Windows Internet Naming Service (WINS) servers and to make the clients use the attacker, or a machine under the control of the attacker, as their default gateway. DHCP spoofing attack This type of attack takes advantage of the way that hardware on most switches operates. Most switches perform only one level of 802.1Q de- encapsulation, which allows an attacker to embed a hidden 802.1Q tag inside the frame. Double Tagging Attack The ________________ switches do not support features or options beyond those that originally came with the switch.

Core layer Configurations are stored within a VLAN database file, called vlan.dat This is a conduit for multiple VLANs between switches and routers. Trunks What is the best practice relative to switch port modes? Do not use the dynamic auto or dynamic desirable. The primary function of this layer is to provide network access to the user. Access layer What is the command to create a VLAN with a valid VLAN ID number 30? vlan 30 This memory provides temporary storage for various applications and processes, including the running IOS, the running configuration file, IP routing table, Ethernet ARP table.
