Question 89

An attacker with access to the inside network of a small company launches a successful STP manipulation attack. What will he do next?

Options:

He will create a SPAN entry on the spoofed root bridge and redirect traffic to his computer.

He will activate OSPF on the spoofed root bridge.

He will repeat this action so that it escalates to a DoS attack.

He will repeat the same attack against all L2 switches of the network.

Question 90

What is one of the advantages of using both symmetric and asymmetric cryptography in SSL/TLS?

Options:

Supporting both types of algorithms allows less-powerful devices such as mobile phones to use symmetric encryption instead.

Symmetric algorithms such as AES provide a failsafe when asymmetric methods fail.

Symmetric encryption allows the server to security transmit the session keys out-of-band.

Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to securely negotiate keys for use with symmetric cryptography.

Question 91

What is a “Collision attack” in cryptography?

Options:

Collision attacks try to get the public key

Collision attacks try to break the hash into three parts to get the plaintext value

Collision attacks try to break the hash into two parts, with the same bytes in each part to get the private key

Collision attacks try to find two inputs producing the same hash

Question 92
