ccna2 theory 30-45 Flashcards
What is the effect of entering the spanning-tree portfast configuration command on a switch?
It enables portfast on a specific switch interface.
Refer to the exhibit. Which route was configured as a static route to a specific network using the next-hop address?
S 10.17.2.0/24 [1/0] via 10.16.2.2
What is the IPv6 prefix that is used for link-local addresses?
FE80::/10
Which two statements are characteristics of routed ports on a multilayer switch? (Choose two.)
In a switched network, they are mostly configured between switches at the core and distribution layers.
They are not associated with a particular VLAN.
Successful inter-VLAN routing has been operating on a network with multiple VLANs across multiple switches for some time. When an inter-switch trunk link fails and Spanning Tree Protocol brings up a backup trunk link, it is reported that hosts on two VLANs can access some, but not all the network resources that could be accessed previously. Hosts on all other VLANS do not have this problem. What is the most likely cause of this problem?
The protected edge port function on the backup trunk interfaces has been disabled.
Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?
interface range GigabitEthernet 0/4 – 5
What action takes place when a frame entering a switch has a multicast destination MAC address?
The switch will forward the frame out all ports except the incoming port.
A junior technician was adding a route to a LAN router. A traceroute to a device on the new network revealed a wrong path and unreachable status. What should be done or checked?
Check the configuration of the exit interface on the new static route.
Select the three PAgP channel establishment modes. (Choose three.)
auto
desirable
on
a static route has been configured in a router. however the destination network no longer exists. what should an administrator do to remove the static route from the routing table
remove the route using the no ip route command
Refer to the exhibit. What can be concluded about the configuration shown on R1?
R1 is configured as a DHCPv4 relay agent.
Refer to the exhibit. R1 has been configured as shown. However, PC1 is not able to receive an IPv4 address. What is the problem?
The ip helper-address command was applied on the wrong interface.
What two default wireless router settings can affect network security? (Choose two.)
The SSID is broadcast.
A well-known administrator password is set.
What is the common term given to SNMP log messages that are generated by network devices and sent to the SNMP server?
traps
