SWRE Final Exam 7 Flashcards
A network administrator is configuring a WLAN. Why would the administrator use RADIUS servers on the network?
to centralize management of multiple WLANs
to restrict access to the WLAN by authorized, authenticated users only
to facilitate group configuration and management of multiple WLANs through a WLC

to restrict access to the WLAN by authorized, authenticated users only
What is the effect of entering the switchport mode access configuration command on a switch?
It enables BPDU guard on a specific port.
It manually enables a trunk link.
It disables an unused port.
It disables DTP on a non-trunking interface.
It disables DTP on a non-trunking interface.
A network administrator has configured a router for stateless DHCPv6 operation. However, users report that workstations are not receiving DNS server information. Which two router configuration lines should be verified to ensure that stateless DHCPv6 service is properly configured? (Choose two.)
The domain-name line is included in the ipv6 dhcp pool section.
The dns-server line is included in the ipv6 dhcp pool section.
The ipv6 nd other-config-flag is entered for the interface that faces the LAN segment.
The address prefix line is included in the ipv6 dhcp pool section.
The ipv6 nd managed-config-flag is entered for the interface that faces the LAN segment.
The dns-server line is included in the ipv6 dhcp pool section.
The ipv6 nd other-config-flag is entered for the interface that faces the LAN segment.
A network administrator is configuring a WLAN. Why would the administrator disable the broadcast feature for the SSID?
to eliminate outsiders scanning for available SSIDs in the area
to centralize management of multiple WLANs
to facilitate group configuration and management of multiple WLANs through a WLC
to provide prioritized service for time-sensitive applications
to eliminate outsiders scanning for available SSIDs in the area
Refer to the exhibit. An administrator is attempting to install an IPv6 static route on router R1 to reach the network attached to router R2. After the static route command is entered, connectivity to the network is still failing. What error has been made in the static route configuration?
The next hop address is incorrect.
The interface is incorrect.
The destination network is incorrect.
The network prefix is incorrect.
The interface is incorrect.
What action takes place when a frame entering a switch has a unicast destination MAC address that is not in the MAC address table?
The switch updates the refresh timer for the entry.
The switch resets the refresh timer on all MAC address table entries.
The switch replaces the old entry and uses the more current port.
The switch will forward the frame out all ports except the incoming port.
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?
Create a floating static route to that network.
Check the configuration on the floating static route and adjust the AD.
Check the configuration of the exit interface on the new static route.
Verify that the static route to the server is present in the routing table.
Check the configuration of the exit interface on the new static route.
What is the effect of entering the ip arp inspection vlan 10 configuration command on a switch?
It specifies the maximum number of L2 addresses allowed on a port.
It enables DAI on specific switch interfaces previously configured with DHCP snooping.
It enables DHCP snooping globally on a switch.
It globally enables BPDU guard on all PortFast-enabled ports.
It enables DAI on specific switch interfaces previously configured with DHCP snooping.
What protocol or technology manages trunk negotiations between switches?
VTP
EtherChannel
DTP
STP
DTP
A network administrator is configuring a WLAN. Why would the administrator apply WPA2 with AES to the WLAN?
to reduce the risk of unauthorized APs being added to the network
to centralize management of multiple WLANs
to provide prioritized service for time-sensitive applications
to provide privacy and integrity to wireless traffic by using encryption
to provide privacy and integrity to wireless traffic by using encryption
Users on a LAN are unable to get to a company web server but are able to get elsewhere. What should be done or checked?
Ensure that the old default route has been removed from the company edge routers.
Verify that the static route to the server is present in the routing table.
Check the configuration on the floating static route and adjust the AD.
Create a floating static route to that network.
Verify that the static route to the server is present in the routing table.
What IPv6 prefix is designed for link-local communication?
2001::/3
ff00::/8
fc::/07
fe80::/10
fe80::/10
What is the effect of entering the ip dhcp snooping limit rate 6 configuration command on a switch?
It displays the IP-to-MAC address associations for switch interfaces.
It enables port security globally on the switch.
It restricts the number of discovery messages, per second, to be received on the interface.
It dynamically learns the L2 address and copies it to the running configuration
it restricts the number of discovery messages, per second, to be received on the interface.
A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?
to eliminate outsiders scanning for available SSIDs in the area
to reduce the risk of unauthorized APs being added to the network
to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range
to reduce the risk of interference by external devices such as microwave ovens
to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range
What is the effect of entering the ip arp inspection validate src-mac configuration command on a switch?
It checks the source L2 address in the Ethernet header against the sender L2 address in the ARP body.
It disables all trunk ports.
It displays the IP-to-MAC address associations for switch interfaces.
It enables portfast on a specific switch interface.
It checks the source L2 address in the Ethernet header against the sender L2 address in the ARP body.
