reset TCP connection alert drop

What mechanism is used by an ASA 5505 device to allow inspected outbound traffic to return to the originating sender who is on an inside network?

stateful packet inspection

What is the purpose of a local username database if multiple ACS servers are configured to provide authentication services?

A local username database provides redundancy if ACS servers become unreachable.

What is a characteristic of a role-based CLI view of router configuration?

A single CLI view can be shared within multiple superviews.

An organization has configured an IPS solution to use atomic alerts. What type of response will occur when a signature is detected?

What is a feature of the TACACS+ protocol?

It encrypts the entire body of the packet for more secure communications.

Why is hashing cryptographically stronger compared to a cyclical redundancy check (CRC)?

It is virtually impossible for two different sets of data to calculate the same hash output.

Keep a secure copy of router operating system images. Configure the router with the maximum amount of memory possible.

What is the one major difference between local AAA authentication and using the login local command when configuring device access authentication?

Local AAA authentication provides a way to configure backup methods of authentication, but login local does not.

What is the benefit of the network-based IPS (NIPS) over host-based IPS (HIPS) deployment models?

The Cisco IOS image file is not visible in the output of the show flash command.

What are two benefits of using a ZPF rather than a Classic Firewall?

The ZPF is not dependent on ACLs. ZPF policies are easy to read and troubleshoot.

What two assurances does digital signing provide about code that is downloaded from the Internet?
