Which situation describes data transmissions over a WAN connection? An employee prints a file through a networked printer that is located in another building. A manager sends an email to all employees in the department with offices that are located in several buildings. An employee shares a database file with a co-worker who is located in a branch office on the other side of the city. A network administrator in the office remotely accesses a web server that is located in the data center at the edge of the campus.

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

Which network scenario will require the use of a WAN? Employee workstations need to obtain dynamically assigned IP addresses. Employees need to connect to the corporate email server through a VPN while traveling. Employees in the branch office need to share files with the headquarters office that is located in a separate building on the same campus network. Employees need to access web pages that are hosted on the corporate web servers in the DMZ within their building.

Employees need to connect to the corporate email server through a VPN while traveling.

What is a disadvantage when both sides of a communication use PAT? Host IPv4 addressing is complicated. End-to-end IPv4 traceability is lost. The flexibility of connections to the Internet is reduced. The security of the communication is negatively impacted.

End-to-end IPv4 traceability is lost.

Which two technologies are categorized as private WAN infrastructures? (Choose two.) cable DSL Frame Relay MetroE VPN

Frame Relay MetroE

Which protocol creates a virtual point-to-point connection to tunnel unencrypted traffic between Cisco routers from a variety of protocols? OSPF IPsec IKE GRE

GRE

Which type of VPN involves passenger, carrier, and transport protocols? GRE over IPsec IPsec virtual tunnel interface MPLS VPN dynamic multipoint VPN

GRE over IPsec

Which type of VPN supports multiple sites by applying configurations to virtual interfaces instead of physical interfaces? IPsec virtual tunnel interface dynamic multipoint VPN MPLS VPN GRE over IPsec

IPsec virtual tunnel interface

Which statement describes an important characteristic of a site-to-site VPN? It must be statically set up. It is ideally suited for use by mobile workers. It requires using a VPN client on the host PC. It is commonly implemented over dialup and cable modem networks. After the initial connection is established, it can dynamically change connection information.

It must be statically set up

Which is a requirement of a site-to-site VPN? It requires a client/server architecture. It requires the placement of a VPN server at the edge of the company network. It requires hosts to use VPN client software to encapsulate traffic. It requires a VPN gateway at each end of the tunnel to encrypt and decrypt traffic.

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 AES DH RSA

MD5 SHA

Which type of VPN has both Layer 2 and Layer 3 implementations? MPLS VPN IPsec virtual tunnel interface dynamic multipoint VPN GRE over IPsec

MPLS VPN

How is "tunneling" accomplished in a VPN? New headers from one or more VPN protocols encapsulate the original packets. All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private. Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers. A dedicated circuit is established between the source and destination devices for the duration of the connection.

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

Which type of VPN connects using the Transport Layer Security (TLS) feature? SSL VPN GRE over IPsec dynamic multipoint VPN IPsec virtual tunnel interface

SSL VPN

Which two WAN infrastructure services are examples of private connections? (Choose two.) T1/E1 wireless DSL cable Frame Relay

T1/E1 Frame Relay

Which statement describes a VPN? VPNs use dedicated physical connections to transfer data between remote users. VPNs use logical connections to create public networks through the Internet. VPNs use open source virtualization software to create the tunnel through the Internet. VPNs use virtual connections to create a private network through a public network.

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.) Both LANs and WANs connect end devices. WANs connect LANs at slower speed bandwidth than LANs connect their internal end devices.​ LANs connect multiple WANs together. WANs must be publicly-owned, but LANs can be owned by either public or private entities. WANs are typically operated through multiple ISPs, but LANs are typically operated by single organizations or individuals.
