Cisco CCNA and CompTIA Practice Questions – SYN Attacks, VLANs, And More
Let’s take a look at your knowledge of topics consisting of SYN assaults and VLANs to your Cisco CCNA, CCNP, and CCENT exam prep. There are questions for the Network+ and Security+ exam as well, and A+ questions are on the manner!
CCNA / CCENT / CompTIA Network+ Certification:
Host A and Host B are inside the identical VLAN. Host C and Host D are in a exceptional VLAN. Host A sends a published. How many other hosts will get hold of it?
Answer: B. The different host in the same VLAN, Host B, will acquire it. Broadcasts are not forwarded to other VLANs.

These unfinished connections result in the network tool now not being capable of take delivery of SYN request from legitimate network hosts, in view that its buffers may be overwhelmed with the fake (and unfinished) requests.
