Refer to the exhibit. The PC is sending a packet to the Server on the remote network. Router R1 is performing NAT overload. From the perspective of the PC, match the NAT address type with the correct IP address. (Not all options are used.)

203.0.113.5 = Outside global 192.0.2.1 = Inside global 10.130.5.76 = Inside local

Refer to the exhibit. R1 is configured for static NAT. What IP address will Internet hosts use to reach PC1?

209.165.200.225

Refer to the exhibit. Which source address is being used by router R1 for packets being forwarded to the Internet?

209.165.200.225

Which situation describes data transmissions over a WAN connection?

An employee shares a database file with a co-worker who is located in a branch office on the other side of the city.

Refer to the exhibit. Static NAT is being configured to allow PC 1 access to the web server on the internal network. What two addresses are needed in place of A and B to complete the static NAT configuration? (Choose two.)

B = 209.165.201.1 A = 10.1.0.13

What is a disadvantage when both sides of a communication use PAT?

End-to-end IPv4 traceability is lost.

A company is considering updating the campus WAN connection. Which two WAN options are examples of the private WAN architecture? (Choose two.)

Ethernet WAN leased line

Which type of VPN supports multiple sites by applying configurations to virtual interfaces instead of physical interfaces?

IPsec virtual tunnel interface

Which statement describes an important characteristic of a site-to-site VPN?

It must be statically set up.

Which is a requirement of a site-to-site VPN?

It requires a VPN gateway at each end of the tunnel to encrypt and decrypt traffic.

What are two hashing algorithms used with IPsec AH to guarantee authenticity? (Choose two.)

MD5 SHA

Refer to the exhibit. A network administrator has configured R2 for PAT. Why is the configuration incorrect?

NAT-POOL2 is bound to the wrong ACL.

How is "tunneling" accomplished in a VPN?

New headers from one or more VPN protocols encapsulate the original packets.

Refer to the exhibit. Based on the output that is shown, what type of NAT has been implemented?

PAT using an external interface

What two algorithms can be part of an IPsec policy to provide encryption and hashing to protect interesting traffic? (Choose two.)

SHA AES

Which two WAN infrastructure services are examples of private connections? (Choose two.)

T1/E1 Frame Relay

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.What problem is causing PC-A to be unable to communicate with the Internet?

The NAT interfaces are not correctly assigned.

Refer to the exhibit. Which two statements are correct based on the output as shown in the exhibit? (Choose two.)

The host with the address 209.165.200.235 will respond to requests by using a source address of 192.168.10.10. The output is the result of the show ip nat translations command.

Refer to the exhibit. A network administrator is viewing the output from the command show ip nat translations . Which statement correctly describes the NAT translation that is occurring on router RT2?​

The traffic from a source IPv4 address of 192.168.254.253 is being translated to 192.0.2.88 by means of static NAT.

Which statement describes a VPN?

VPNs use virtual connections to create a private network through a public network.

Which two statements about the relationship between LANs and WANs are true? (Choose two.)

WANs connect LANs at slower speed bandwidth than LANs connect their internal end devices.​ WANs are typically operated through multiple ISPs, but LANs are typically operated by single organizations or individuals.

Which two types of VPNs are examples of enterprise-managed remote access VPNs? (Choose two.)

client-based IPsec VPN clientless SSL VPN

Which VPN solution allows the use of a web browser to establish a secure, remote-access VPN tunnel to the ASA?

clientless SSL

Match each component of a WAN connection to its description. (Not all options are used.)

devices and inside wiring located on the enterprise edge and which connect to a carrier link. -> customer premises equipment a point that is established in a building or complex to separate customer equipment from service provider equipment. -> demarcation point customer devices that pass the data from customer network or host computer for transmission over the WAN. -> data terminal equipment

Refer to the exhibit. From the perspective of users behind the NAT router, what type of NAT address is 209.165.201.1?

inside global

Which IPsec security function provides assurance that the data received via a VPN has not been modified in transit?

integrity

What does NAT overloading use to track multiple internal hosts that use one inside global address?

port numbers

What type of address is 64.101.198.197?

public

Which two technologies provide enterprise-managed VPN solutions? (Choose two.)

site-to-site VPN remote access VPN

Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet to and external server at the IP address 209.165.200.254 across a router R1 that running dynamic NAT. (Not all options are used.)

step 5 => R1 replaces the address 192.168.10.10 with a translated inside global address. step 2 => R1 checks the NAT configuration to determine if this packet should be translated. step 4 => R1 selects an available global address from the dynamic address pool. step 1 => The host sends packets that request a connection to the server at the address 209.165.200.254 step 3 => If there is no translation entry for this IP address, R1 determines that the source address 192.168.10.10 must be translated

What two addresses are specified in a static NAT configuration?

the inside local and the inside global

Which circumstance would result in an enterprise deciding to implement a corporate WAN?

when its employees become distributed across many branch locations
