As part of the new security policy, all switches on the network are configured to automatically learn MAC addresses for each port. All running configurations are saved at the start and close of every business day. A severe thunderstorm causes an extended power outage several hours after the close of business. When the switches are brought back online, the dynamically learned MAC addresses are retained. Which port security configuration enabled this?

An administrator is trying to remove configurations from a switch. After using the command erase startup-config and reloading the switch, the administrator finds that VLANs 10 and 100 still exist on the switch. Why were these VLANs not removed?
Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.)
Refer to the exhibit. Based on the exhibited configuration and output, why is VLAN 99 missing?
Which two statements are correct if a configured NTP master on a network cannot reach any clock with a lower stratum number? (Choose two.)
Refer to the exhibit. An administrator is examining the message in a syslog server. What can be determined from the message?
A network engineer has created a standard ACL to control SSH access to a router. Which command will apply the ACL to the VTY lines?

What is the effect of configuring the ipv6 unicast-routing command on a router?
Refer to the exhibit. Inter-VLAN communication between VLAN 10, VLAN 20, and VLAN 30 is not successful. What is the problem?
Refer to the exhibit. Which route was configured as a static route to a specific network using the next-hop address?
Refer to the exhibit. A network engineer is preparing to upgrade the IOS system image on a Cisco 2901 router. Based on the output shown, how much space is available for the new image?
The computers used by the network administrators for a school are on the 10.7.0.0/27 network. Which two commands are needed at a minimum to apply an ACL that will ensure that only devices that are used by the network administrators will be allowed Telnet access to the routers? (Choose two.)
