Which type of address is the public IP address of a NAT device?

A. outside global
B. outside local
C. inside global
D. inside local
E. outside public
F. inside public

Correct Answer: C

Explanation:

Explanation:
NAT use four types of addresses:
* Inside local address – The IP address assigned to a host on the inside network. The address is usually not an IP address assigned by the Internet Network Information Center (InterNIC) or service provider. This ddress is likely to be an RFC 1918 private address.
* Inside global address – A legitimate IP address assigned by the InterNIC or service provider that representsone or more inside local IP addresses to the outside world.
* Outside local address – The IP address of an outside host as it is known to the hosts on the inside network.
* Outside global address – The IP address assigned to a host on the outside network. The owner of the host assigns this address.

An engineer is configuring NAT to translate the source subnet of 10.10.0.0/24 to any one of three addresses: 192.168.3.1, 192.168.3.2, or 192.168.3.3. Which configuration should be used?

A. enable
configure terminal
ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30
access-list 1 permit 10.10.0.0 0.0.0.255
ip nat outside destination list 1 pool mypool
interface g1/1
ip nat inside
interface g1/2
ip nat outside
B. enable
configure terminal
ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30
access-list 1 permit 10.10.0.0 0.0.0.254
ip nat inside source list 1 pool mypool
interface g1/1
ip nat inside
interface g1/2
ip nat outside
C. enable
configure terminal
ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30
route map permit 10.10.0.0 255.255.255.0
ip nat outside destination list 1 pool mypool
interface g1/1
ip nat inside
interface g1/2
ip nat outside
D. enable
configure terminal

What is the primary purpose of a First Hop Redundancy Protocol?

A. It allows directly connected neighbors to share configuration information
B. It reduces routing failures by allowing Layer 3 load balancing between OSPF neighbors that have the same link metric
C. It allows a router to use bridge priorities to create multiple loop-free paths to a single destination
D. It reduces routing failures by allowing more than one router to represent itself as the default gateway of a network

Correct Answer: D

To configure authentication, perform this task in privileged mode:
Step 1: Configure an authentication key pair for NTP and specify whether the key will be trusted or untrusted.
Step 2: Set the IP address of the NTP server and the public key.
Step 3: Enable NTP client mode.
Step 4: Enable NTP authentication.
Step 5: Verify the NTP configuration.
