Branch users were able to access a site in the morning but have had no connectivity with the site since lunch time. What should be done or checked?
Use the “show ip interface brief” command to see if an interface is down.
What is the effect of entering the switchport port-security configuration command on a switch?
It enables port security on an interface.
A network administrator is configuring a WLAN. Why would the administrator use multiple lightweight APs?
to facilitate group configuration and management of multiple WLANs through a WLC
Refer to the exhibit. PC-A and PC-B are both in VLAN 60. PC-A is unable to communicate with PC-B. What is the problem?
The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.
A network administrator is configuring a WLAN. Why would the administrator use RADIUS servers on the network?
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 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 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
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 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 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.
What is the effect of entering the ip arp inspection vlan 10 configuration command on a switch?
It enables DAI on specific switch interfaces previously configured with DHCP snooping.
What protocol or technology manages trunk negotiations between switches?
DTP
A network administrator is configuring a WLAN. Why would the administrator apply WPA2 with AES to the WLAN?
to provide privacy and integrity to wireless traffic by using encryption
