Apply the ACL to the vty lines without the in or out option required when applying ACLs to interfaces.
The ACL is applied to the Telnet port with the ip access-group command.
The ACL must be applied to each vty line individually.
The ACL should be applied to all vty lines in the in direction to prevent an unwanted user from connecting to an unsecured port.
FW(config)# interface g0/1 FW(config-if)# ip inspect OUTBOUND in FW(config-if)# ip access-group INSIDE out
FW(config)# interface g0/1 FW(config-if)# ip inspect OUTBOUND in FW(config-if)# ip access-group INSIDE in
FW(config)# interface g0/0 FW(config-if)# ip inspect OUTBOUND in FW(config-if)# ip access-group INSIDE in
W(config)# interface g0/0 FW(config-if)# ip inspect INSIDE in FW(config-if)# ip access-group OUTBOUND in
SSL VPNs provide support for more applications.
SSL VPNs do not require any pre-installed client software.
SSL VPNs provide superior authentication.
SSL VPNs provide stronger encryption as a remote-access solution.
Network IPS is operating system-dependent and must be customized for each platform.
Network IPS is incapable of examining encrypted traffic.
Network IPS is unable to provide a clear indication of the extent to which the network is being attacked.
Network IPS sensors are difficult to deploy when new networks are added.
Network IPS has a difficult time reconstructing fragmented traffic to determine if an attack was successful.
To have stronger encryption options
To support secure access for users on a multitude of devices
To have stronger authentication options
To provide stronger overall security
Cisco VPN client mode

It sets an access class ACL on VTY lines.
It enables TCP intercepts.
It provides an option for configuring SNMPv3 on all routers.
It enables the Secure Copy Protocol (SCP).
It supports AAA configuration.
An IDS uses signature-based technology to detect malicious packets, whereas an IPS uses profile-based technology.
An IDS would allow malicious traffic to pass before it is addressed, whereas an IPS stops it immediately.
An IDS can negatively impact the packet flow, whereas an IPS can not.
An IDS needs to be deployed together with a firewall device, whereas an IPS can replace a firewall.
Use ISL encapsulation on all trunk links.
Disable STP on all nontrunk ports.
Disable trunk negotiation for trunk ports and statically set nontrunk ports as access ports.
Use VLAN 1 as the native VLAN on trunk ports.
A packet-filtering firewall typically can filter up to the transport layer, whereas a stateful firewall can filter up to the session layer.
Both stateful and packet-filtering firewalls can filter at the application layer.
A packet-filtering firewall uses session layer information to track the state of a connection, whereas a stateful firewall uses application layer information to track the state of a connection.
A stateful firewall can filter application layer information, whereas a packet-filtering firewall cannot filter beyond the network layer.

ESA provides isolation between processes.
It obtains real-time updates from the Cisco SIO.

It combines advanced threat defense and secure mobility for email.
The Telnet connection between RouterA and RouterB is not working correctly.
The enable password and the Telnet password need to be the same.
The password cisco123 is wrong.
The administrator does not have enough rights on the PC that is being used.
The root user must be assigned to each privilege level that is defined.
It is required that all 16 privilege levels be defined, whether they are used or not.
Views are required to define the CLI commands that each user can access.
There is no access control to specific interfaces on a router.
Creating a user account that needs access to most but not all commands can be a tedious process.
Commands set on a higher privilege level are not available for lower privilege users.
The data is divided into three blocks of equal length for encryption.
The data is encrypted using a key length that is three times longer than the key used for DES.
The data is encrypted three times with three different keys.
The data is encrypted, decrypted, and encrypted using three different keys.
Storm control with the trap option
PortFast with BPDU guard enabled

Router management interfaces must be manually assigned to the self zone.
A router interface can belong to multiple zones.
The pass action works in only one direction.
Service policies are applied in interface configuration mode.
