Question 97
Which two criteria must a certificate meet before the WSA uses it to decrypt application traffic? (Choose two.)
Correct Answer: B,E
The WSA uses a root certificate and a private key to decrypt HTTPS traffic. The root certificate must reside in the trusted store of the WSA, and it must be able to sign server certificates on the fly. The server certificates that the WSA generates must contain a SAN (Subject Alternative Name) field, which specifies the hostnames or IP addresses that the certificate is valid for. The SAN field is required by modern browsers and applications to verify the identity of the server. If the WSA does not include a SAN field in the server certificate, the browser or application may reject the connection or display a warning message. The other options are not correct because: * A. The current date is not a criterion for the WSA to use a certificate to decrypt application traffic. The WSA checks the validity period of the certificate, which includes the start date and the end date. The current date must be within the validity period, but it does not have to be the same as the start date or the end date. * C. The root certificate that the WSA uses to decrypt HTTPS traffic does not have to reside in the trusted store of the endpoint. However, the endpoint must trust the root certificate in order to accept the server certificate that the WSA generates. This can be achieved by manually installing the root certificate on the endpoint, or by using a group policy or a certificate management system to distribute the root certificate to the endpoints. * D. The root certificate that the WSA uses to decrypt HTTPS traffic does not have to be signed by an internal CA. The WSA can generate its own self-signed root certificate, or it can use a root certificate that is signed by an external CA. However, the root certificate must be trusted by the endpoints, as explained in option C.

Question 98
DoS attacks are categorized as what?
Correct Answer: B
DoS attacks are categorized as flood attacks or crash attacks. Flood attacks are the more common form of DoS attacks. They occur when the attacked system is overwhelmed by large amounts of traffic that the server is unable to handle. The system eventually stops. Some examples of flood attacks are ICMP flood, SYN flood, and UDP flood. Crash attacks are less frequent and they exploit flaws in the targeted system. The result is that the system crashes. Some examples of crash attacks are Ping of Death, Teardrop, and Land.
