Question 26

For the following items, which one is the weakness of rate limiting as a response to a DoS attack?

A.Rate limiting does not detect attacks.

B.Rate limiting is too processor-intensive.

C.Rate limiting does not drop enough packets.

D.Rate limiting only works on inbound traffic.

Question 27

You are designing an optical network. Your goal is to ensure that your design contains the highest degree of resiliency. In which two ways will you leverage a wavelength-switched optical network solution in your network design? (Choose two.)

A.a wavelength-switched optical network assigns routing and wavelength information

B.a wavelength-switched optical network eliminates the need for dispersion compensating units in a network

C.a wavelength-switched optical network guarantees restoration based strictly on the shortest path available

D.a wavelength-switched optical network takes linear and nonlinear optical impairment calculation into account

Question 28

Refer to the exhibit.

You are developing a migration plan to enable IPv6 in your IPv4 network. Starting at R3 and assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the link from R3 to R2?

A.Loopback reachability between all routers for IPv4 is lost.

B.All routers except R2 are reachable through IPv4.

C.Only R3 and R2 have IPv4 and IPv6 reachability.

D.R3 advertises the link from R3-R2 to R1, R4 and R5 only.

E.R2 receives an IPv6 default route from R3.

Question 29

Company ABC uses IPv4-only. Recently they started deploying new endpoint devices. For operational reasons, IPv6 cannot be disabled on these new endpoint devices. Which security measure prevents the new endpoint from learning an IPv6 prefix from an attacker?

A.Router Advertisement Guard

B.Secure Neighbor Discovery

C.Source Guard and Prefix Guard

D.Prefix Guard
