A new MPLS network link has been established between a company and its business partner. The
link provides logical isolation in order to prevent access from other business partners. Which of the
following should be applied in order to achieve confidentiality and integrity of all data across the
link?
A.
MPLS should be run in IPVPN mode.
B.
SSL/TLS for all application flows.
C.
IPSec VPN tunnels on top of the MPLS link.
D.
HTTPS and SSH for all application flows.
Explanation:
Multiprotocol Label Switching (MPLS) is a type of data-carrying technique for high-performance telecommunications networks.
MPLS directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table.
Explanation:
IPSec can very well be used with MPLS. IPSec could provide VPN tunnels on top if the MPLS link.
Internet Protocol Security (IPSec) isn’t a tunneling protocol, but it’s used in conjunction with tunneling protocols.
IPSec is oriented primarily toward LAN-to-LAN connections, but it can also be used with dial-up connections.
IPSec provides secure authentication and encryption of data and headers; this makes it a good choice for security.
