Question 2 of 172

A second set of traffic selectors is negotiated between two peers using IKEv2. Which IKEv2 packet will contain details of the exchange?

IKEv2 IKE_SA_INIT

IKEv2 INFORMATIONAL

IKEv2 CREATE_CHILD_SA

IKEv2 IKE_AUTH

Correct Answer: C

The IKEv2 CREATE_CHILD_SA packet is used to establish new Child SAs or to rekey existing ones within an already established IKE SA. This packet contains the details of the exchange, including the traffic selectors, which specify the IP addresses and port numbers involved. This matches the requirement of the question where a second set of traffic selectors needs to be negotiated.

Question 3 of 172

Refer to the exhibit. The DMVPN tunnel is dropping randomly and no tunnel protection is configured. Which spoke configuration mitigates tunnel drops?

Correct Answer:

The correct mitigation for the tunnel drops in the given DMVPN configuration involves setting appropriate NHRP hold and registration timeout values. The default NHRP registration timeout is typically one-third of the holdtime value. To prevent random tunnel drops, it is crucial to ensure that the registration timeout is less than the holdtime to re-register the tunnel before it expires. Among the given options, option C sets the holdtime to 120 seconds and the registration timeout to 20 seconds, which is less than the holdtime, ensuring a timely re-registration of the tunnel. This configuration aligns with the recommendation to prevent tunnel drops, making option C the most effective choice.

Question 4 of 172

On a FlexVPN hub-and-spoke topology where spoke-to-spoke tunnels are not allowed, which command is needed for the hub to be able to terminate FlexVPN tunnels?

interface virtual-access

ip nhrp redirect

interface tunnel

interface virtual-template

Correct Answer: D

In a FlexVPN hub-and-spoke topology where spoke-to-spoke tunnels are not allowed, the hub needs the capability to efficiently manage multiple connections from spokes. This requires the use of a virtual template interface. The 'interface virtual-template' command is utilized for creating and managing these interfaces, enabling the hub to terminate multiple FlexVPN tunnels. This is important for managing a large number of spokes efficiently and dynamically, which is the core requirement in such a topology.

Question 5 of 172

Which statement about GETVPN is true?

The configuration that defines which traffic to encrypt originates from the key server.

TEK rekeys can be load-balanced between two key servers operating in COOP.

The pseudotime that is used for replay checking is synchronized via NTP.

Group members must acknowledge all KEK and TEK rekeys, regardless of configuration.

Correct Answer: C

GETVPN uses pseudotime for replay checking, and this pseudotime is synchronized via NTP (Network Time Protocol). This ensures that all group members have a consistent time reference to prevent replay attacks. This synchronization is crucial for maintaining the integrity and security of the encrypted communications within the group.
