What are two uses of an access control list? (Choose two.)
- ACLs can control which areas a host can access on a network.
- ACLs provide a basic level of security for network access.
- Standard ACLs can restrict access to specific applications and ports.

- protocol type
- source IP address
- source TCP port
What is the role of an IPS?
- to detect patterns of malicious traffic by the use of signature files
- to filter traffic based on defined rules and connection context
- to filter traffic based on Layer 7 information
- to enforce access control policies based on packet content

What does the TACACS+ protocol provide in a AAA deployment?
- AAA connectivity via UDP
- compatibility with previous TACACS protocols
- authorization on a per-user or per-group basis
- password encryption without encrypting the packet

- GRE
- IPsec
- OSPF
- IKE
Which two statements are true about NTP servers in an enterprise network? (Choose two.)
- NTP servers at stratum 1 are directly connected to an authoritative time source.
- NTP servers ensure an accurate time stamp on logging and debugging information.
- There can only be one NTP server on an enterprise network.
- All NTP servers synchronize directly to a stratum 1 time source.
- NTP servers control the mean time between failures (MTBF) for key network devices.
What is true concerning physical and logical topologies?
- Physical topologies display the IP addressing scheme of each network.
- Logical topologies refer to how a network transfers data between devices.
- The logical topology is always the same as the physical topology.
- Physical topologies are concerned with how a network transfers frames.

What is a function of a proxy firewall?
- uses signatures to detect patterns in network traffic
- connects to remote servers on behalf of clients
- drops or forwards traffic based on packet header information
- filters IP traffic between bridged interfaces
What is the function of the distribution layer of the three-layer network design model?
- aggregating access layer connections
- providing high speed connection to the network edge
