Refer to the exhibit. You notice that the email volume history has been abnormally high. Which potential result is true?
A. Email sent from your domain might be filtered by the recipient.
B. Messages sent to your domain may be queued up until traffic dies down.
C. Several hosts in your network may be compromised.
D. Packets may be dropped due to network congestion.
Yeah sure, e-mails will be queued up when the traffic is high, and will take their turns til the traffic dies down, but the keyword is “ABNORMALLY”, if your network traffic is always high, then you know you need to wait for it to come to your inbox, however, if everything is smooth and suddenly or as the keyword (ABNORMALLY) gets high, you better think twice and check because the hosts in the network might already been compromised and are being used in a botnet.
There are 3 different answers given here. Why is/isn’t the answer C?
This is a security class, not a systems administration class…….
I believe “C” is the correct answer……. we can’t overthink these questions……
Several hosts “may” be compromised. Compromised hosts COULD be spewing larger than normal amounts of email.
I’m inclined to agree with you. This is a Security class after all. Other sources also agree that the answer is “C” .
Is ther any posibility that traffic has been tuneled inside the SMTP traffic for exfiltrating?
i think it is B
check this link : https://supportforums.cisco.com/t5/email-security/senderbase-email-volume-history-too-high/td-p/2709910
i concur with B as well
Generally, when email volume is high, messages get queued, so B
Is this answer correct? I think it’s A.
Why are you saying its A?
