Question 6

What benefit does dynamic routing offer?

Lower cost

Faster transfer

Optimal routes

All of the above

A and B above only

B and C above only

Question 7

What is an access control list (ACL), and how is an ACL used?

An ACL consists of parity bits, checksums and cyclic redundancy to prevent unauthorized access to packets

An ACL is a secret key for encryption to make the data safe for transmission

An ACL is a binding to connect the three elements of a packet (datagram) for secure transmission

An ACL identifies who is allowed to access specific information

Question 8

When a VPN uses IP-in-IP tunneling, what prevents an attacker from reading the header of the original datagram?

The encrypted frame is placed in a datagram

The datagram is encrypted and placed in a second datagram

The frame is encrypted and placed in a second frame

The header is encrypted and sent as a separate fragment

Question 9

What term is used to describe the mapping between a protocol address and a hardware address?

Virtual Private Network Protocol

Virtual Local Area Network Protocol

Trunking Address Protocol

Address Resolution Protocol

Question 10

ARP only permits address resolution to occur on a single network. Does it make sense to send an ARP request to a remote server in an IP datagram? Why or why not? (yes or no)

Yes, ARP is not restricted to IP addresses or specific hardware addresses in theory, the protocol can be used to bind an arbitrary high-level address to an arbitrary hardware address, as ARP allows datagrams to transition across the Internet and enters all known entries into cache

No, although the ARP message format is sufficiently general to allow arbitrary protocol and hardware addresses, ARP is almost always used to bind an IP address to a 48-bit Ethernet address
