14 Questions4 MinutesCreated by ConfiguringShield42

Which of the following could be part of both an IKEv1 Phase 1 and IKEv1 Phase 2 policy? (Choose all that apply.)

MD5

AES

RSA

How is it possible that a packet with a private Layer 3 destination address is forwarded over the Internet?

It is encapsulated into another packet, and the Internet only sees the outside valid IP destination address.

It cannot be sent. It will always be dropped.

The Internet does not filter private addresses, only some public addresses, based on policy.

NAT is used to change the destination IP address before the packet is sent.

What is the method for specifying the IKEv1 Phase 2 encryption method?

Crypto ACLs

Crypto isakmp policy

Crypto ipsec transform-set

RSA signatures

Which of the following potentially could be negotiated during IKEv1 Phase 2? (Choose all that apply.)

Hashing

DH group

Encryption

Authentication method

Which of the following is never part of an IKEv1 Phase 2 process?

Main mode

Specifying a hash (HMAC)

Running DH (PFS)

Negotiating the transform set to use

Which encryption method will be used to protect the negotiation of the IPsec (IKEv1 Phase 2) tunnel?

The one negotiated in the transform set.

The one negotiated for the IKEv1 Phase 2 tunnel.

The one negotiated in the ISAKMP policy.

There is no encryption during this time; that is why DH is used.

Which is the most secure method for authentication of IKEv1 Phase 1?

RSA signatures, using digital certificates to exchange public keys

PSK

DH group 5

Symmetrical AES-256

Which of the following would cause a VPN tunnel using IPsec to never initialize or work correctly? (Choose all that apply.)

Incompatible IKEv1 Phase 2 transform sets

Incorrect pre-shared keys or missing digital certificates

Lack of interesting traffic

Incorrect routing

What is the purpose of NAT exemption?

To bypass NAT in the remote peer

To bypass NAT for all traffic not sent over the IPsec tunnel

To bypass NAT for traffic in the VPN tunnel

To never bypass NAT in the local or remote peer

Which of the following commands are useful when troubleshooting VPN problems in the Cisco ASA? (Choose all that apply.)
