QUESTION 8 NMAP and NESSUS both can be used for port scanning. NESSUS also gives an output about the vulnerabilities. But it's not free, like NMAP. The NMAP can get information about OS and Application versions this information can be used along with CVE to find 0-day vulnerabilities in the OS and applications this information can be used along with CVE to find known vulnerabilities in the OS and applications. this information can't be used to find known vulnerabilities in the OS and applications this information is useful for an attacker but can't help in patch management. QUESTION 9 0-day vulnerabilities should be checked for a patch on NVD. do not have a patch. are due to buffer overflow can't result in attacks
