Q:161-180 Flashcards
- What is the effect of entering the show ip dhcp snooping binding configuration command on a switch?
It switches a trunk port to access mode.
It checks the source L2 address in the Ethernet header against the sender L2 address in the ARP body.
It restricts the number of discovery messages, per second, to be received on the interface.
It displays the IP-to-MAC address associations for switch interfaces.
It displays the IP-to-MAC address associations for switch interfaces.
- What action takes place when the source MAC address of a frame entering a switch is in the MAC address table?
The switch forwards the frame out of the specified port.
The switch updates the refresh timer for the entry.
The switch replaces the old entry and uses the more current port.
The switch adds a MAC address table entry for the destination MAC address and the egress port.
The switch updates the refresh timer for the entry.
- A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?
Add more switches so that fewer devices are on a particular switch.
Replace the switches with switches that have more ports per switch. This will allow more devices on a particular switch.
Segment the LAN into smaller LANs and route between them.*
Replace at least half of the switches with hubs to reduce the size of the broadcast domain.
Segment the LAN into smaller LANs and route between them.*
- What defines a host route on a Cisco router?
The link-local address is added automatically to the routing table as an IPv6 host route.
An IPv4 static host route configuration uses a destination IP address of a specific device and a /32 subnet mask.
A host route is designated with a C in the routing table.
A static IPv6 host route must include the interface type and the interface number of the next hop router.
An IPv4 static host route configuration uses a destination IP address of a specific device and a /32 subnet mask.
- What else is required when configuring an IPv6 static route using a next-hop link-local address?
administrative distance
ip address of the neighbor router
network number and subnet mask on the interface of the neighbor router
interface number and type
interface number and type
