Formative 9 Flashcards
How do cybercriminals make use of a malicious iFrame?
The iFrame allows the browser to load a web page from another source.
The attacker embeds malicious content in business appropriate files.
The attacker redirects traffic to an incorrect DNS server.
The iFrame allows multiple DNS subdomains to be used.
The iFrame allows the browser to load a web page from another source.
In which way does the use of HTTPS increase the security monitoring challenges within enterprise networks?
HTTPS traffic is much faster than HTTP traffic.
HTTPS traffic enables end-to-end encryption.
HTTPS traffic does not require authentication.
HTTPS traffic can carry a much larger data payload than HTTP can carry.
HTTPS traffic enables end-to-end encryption.

Which statement describes the function provided by the Tor network?
It distributes user packets through load balancing.
It allows users to browse the Internet anonymously.
It conceals packet contents by establishing end-to-end tunnels.
It manipulates packets by mapping IP addresses between two networks.
It allows users to browse the Internet anonymously.
How can NAT/PAT complicate network security monitoring if NetFlow is being used?
It changes the source of destination MAC addresses.
It conceals the contents of a packet by encrypting the data payload.
It disguises the application initiated by a user by manipulating port numbers.
It hides internal IP addresses by allowing them to share one or a few outside IP addresses.
It hides internal IP addresses by allowing them to share one or a few outside IP addresses.
A cyberanalyst is reviewing an entry-point ACL. What three types of ICMP traffic should be allowed to access an internal network from the internet? (Choose three.)
request
reply
time exceeded
squelch
ping

A company decides to purchase a device capable of managing load balancing so that traffic will be distributed between their servers. What could be a potential problem using the new device on the network?
It will require the purchase of more servers so that existing servers are not overwhelmed.
The LBM probe messages may appear as suspicious traffic.
The traffic will require more bandwidth to send to multiple servers.
All links to redundant servers will require encrypted tunneling protocols.
It will cause extra traffic going to a server resource that is not available.
The LBM probe messages may appear as suspicious traffic.
