A company needs a device or service that ends VPN connections and links them to its protected network. Which VPN component performs this role?

A
It carries encapsulated packets across the intervening network.
B
It records user activity but does not terminate VPN connections.

D
It replaces the need for access policy.

Select all security protections that a secure VPN commonly combines to protect communication.

A
Encryption, which transforms readable data into ciphertext
B
Tunneling, which by itself guarantees that packets cannot be read
C
Integrity protection, which helps detect alteration
D
Authentication, which verifies a user or VPN peer
E
Access policy, which automatically encrypts every packet

In IPsec tunnel mode, what happens to the original IP packet?

A
It encrypts only the outer routing headers and leaves the original packet outside the tunnel.
B
It protects an entire original IP packet by encapsulating it in a new packet.
C
It authenticates a user but does not protect data packets.
D
It connects a user device directly to a VPN client.

A company wants permitted traffic to pass between the networks at its branch office and headquarters through a protected connection. Which VPN design best fits this goal?

A
A remote-access VPN, because each branch employee must connect individually from a personal device
B
An access policy, because it connects two networks without VPN gateways
C
A public transport network, because it provides the protected connection itself
D
A site-to-site VPN, because gateways can connect the two locations’ networks

A VPN sends private-network traffic across an intervening public network by tunneling. Which description correctly explains how tunneling carries the traffic?

A
The original packet is carried inside another packet, whose outer headers support routing across the intervening network.
B
The original packet is converted into a user credential before it crosses the network.
C
The original packet is discarded and replaced by a packet generated at the destination.
D
The original packet is split into separate encrypted keys.
