QUESTION 2

The network designer needs to consider the number of multicast applications and sources in the network to provide the most robust network possible. Which of the following is a consideration the designer must also address?

 

A.

The IGPs should utilize authentication to avoid being the most vulnerable component

B.

With SSM source or receiver attacks are not possible

C.

With Shared Trees access control is always applied at the RP

D.

Limit the rate of Register messages to the RP to prevent specific hosts from being attacked on a PIM-SM network

QUESTION 3

Which two protocol characteristics should be most considered when designing a single unified fabric for the Data Center? (Choose two.)

 

A.

FCIP or FCoE allow for easier integration by using the Fibre Channel Protocol (FCP) and Fibre Channel framing

C.

FCIP and iSCSI has higher overhead than FCoE owing to TCP/IP

D.

FCoE was initially developed to be used as a switch-to-switch protocol, while FCIP is primarily meant to be used as an access layer protocol to connect hosts and storage to a Fibre Channel SAN

E.

FCoE requires gateway functionality to integrate into an existing Fibre Channel network

 

Correct Answer: AC

B.

Maintaining access rules, based on the source IP of the client, on an internal firewall drawn from a headend RADIUS server is the most secure deployment

C.

VPN Headend routing using Reverse Route Injection (RRI) with distribution is recommended when the remote user community is small and dedicated DHCP scopes are in place

D.

Clientless SSL VPNs provide more granular access control than SSL VPN clients (thin or thick), including at Layer7
