Addresses that are to be translated
Addresses that are assigned to a NAT pool
Addresses that are allowed out of the router
Addresses that are accessible from the inside network
Traffic is only accepted from and forwarded to SDM-trusted Cisco routers.
Security testing is performed and the results are saved as a text file stored in NVRAM.
All traffic that enters the router is quarantined and checked for viruses before being forwarded.
The router is tested for any potential security problems and all recommended security-related configuration changes will be automatically applied.

Named ACLs are less efficient than numbered ACLs.
Standard ACLs should be applied inside the core layer.
Place standard ACLs as close to the destination as possible.
ACLs applied to outbound interfaces require fewer router resources.
Extended ACLs should be applied closest to the source that is specified by the ACL.

To determine the time it takes for the network to self recover from a failure
To determine which areas in the network are underutilized or overutilized
To determine the performance of the network during the normal hours of operation
To determine what thresholds should be set for the devices that need to be monitored
To determine the areas in the network which should not be included in the monitoring process
To determine the number of users whose access to network resources should be restricted
There is an implicit deny at the end of all access lists.
One access list per port, per protocol, per direction is permitted
Access list entries should filter in the order from general to specific.
The term “inbound” refers to traffic that enters the network from the router interface where the ACL is applied.
Standard ACLs should be applied closest to the source while extended ACLs should be applied closest to the destination
LCP sets up the PPP connection and its parameters. NCP terminates the PPP connection
LCP sets up the PPP connection and its parameters. NCP handles higher layer protocol configurations
LCP includes the link-establishment phase. NCP includes link-maintenance and link-termination phases.
LCP negotiates options for multiple network layer protocols. NCP agrees automatically on encapsulation formats.

The frame-relay map statement is incorrect
The S0/0/0 interface of router R1 is administratively down.
The S0/0/0 interface of router R2 has an incorrect IP address.
There is a Layer 2 loop.
The VTP domain names do not match.
Only one switch can be in server mode
S2 has a higher spanning-tree priority for VLAN 11 than S1 does.

10.10.10.1 is most likely assigned to the local LAN interface.
10.10.10.1 through 10.10.10.255 is available to be assigned to users.
All DHCP clients looking for an IP address will use 10.10.10.1 and 10.10.10.2.
All DHCP clients in the 10.10.10.0/24 network will use 10.10.10.2 as the default gateway.
IPv6 traffic-forwarding is enabled on the interface.
A link-local IPv6 address is automatically configured on the interface.
A global unicast IPv6 address is dynamically configured the interface.
Any IPv4 addresses that are assigned to the interface are replaced with an IPv6 address.
PAP uses a two-way handshake.
The password is unique and random.
PAP conducts periodic password challenges.
PAP uses MD5 hashing to keep the password secure.
