Q348. Deploying a wildcard certificate is one strategy to: 

A. Secure the certificate’s private key. 

B. Increase the certificate’s encryption key length. 

C. Extend the renewal date of the certificate. 

D. Reduce the certificate management burden. 

Answer:

Explanation: 

A wildcard certificate is a public key certificate which can be used with multiple subdomains of a domain. This saves money and reduces the management burden of managing multiple certificates, one for each subdomain. 

A single Wildcard certificate for *.example.com, will secure all these domains: payment.example.com contact.example.com 

login-secure.example.com 

www.example.com 

Because the wildcard only covers one level of subdomains (the asterisk doesn't match full stops), 

these domains would not be valid for the certificate: 

test.login.example.com

Q350. Which of the following is described as an attack against an application using a malicious file? 

A. Client side attack 

B. Spam 

C. Impersonation attack 

D. Phishing attack 

Answer:

Explanation: 

In this question, a malicious file is used to attack an application. If the application is running on a 

client computer, this would be a client side attack. Attacking a service or application on a server 

would be a server side attack. 

Client-side attacks target vulnerabilities in client applications interacting with a malicious data. The 

difference is the client is the one initiating the bad connection. 

Client-side attacks are becoming more popular. This is because server side attacks are not as 

easy as they once were according to apache.org. 

Attackers are finding success going after weaknesses in desktop applications such as browsers, 

media players, common office applications and e-mail clients. 

To defend against client-side attacks keep-up the most current application patch levels, keep 

antivirus software updated and keep authorized software to a minimum.
