Let's mental measurement your awareness of UDP, TCP, smurf attacks, EIGRP, and more than near these questions designed to facilitate you concoct for natural event on your CCENT, CCNA, CCNP, Network , and Security citations exams!
CCENT Certification / Network Certification:

Answer: C. DNS runs on left 53, some on TCP and UDP.
Briefly limit the permanent status "smurf attack". (Not too briefly, though!)
Answer: Basically, a smurf invasion involves sends ICMP Echo packets (pings) next to the meant victim's IP computer address fixed as the fountain of the Echo packets. This transference takes the type of a orientated broadcast, which implementation that quite a few hosts can get it - and then retort next to ICMP Echo Replies, which will all be sent to the ordained subject.
R1 and R3 are head-on together at their individual Serial1 interfaces via a DTE/DCE cable. What tell will explain to you whether the interface is related to to the DTE or DCE end of the cable?
Answer: Run spectacle businessperson sequent 1 on either skilled worker - the DTE / DCE hearsay is adjacent the top of the product.
CCNP Certification / BSCI Exam:
DUAL has unconcealed four at all paths to a faraway network, near the stalking metrics: PathA, 1500. PathB, 1500. PathC, 2600. PathD, 3100. What instruct will let EIGRP to use the archetypal cardinal paths lacking victimisation the fourth?
Answer: divergence 2 would do the job. Any path beside a metric linear unit of 3000 or lower will be utilized; locale it to 3 would bring on PathD into the equation.
CCNP Certification / BCMSN Exam:
What is the prime goal of IEEE 802.3ac?
Answer: The IEEE 802.3ac normal allows the peak skeleton length to be lengthy to 1522 bytes, which implementation the dot1q 4-byte header doesn't impose complications in transfer.
CCNP Certification / ONT Exam:
Which queueing plan of action gives superiority to interactive, low-bandwidth communication theory by default?
Answer: Weighted Fair Queueing (WFQ) gives priority to interactive, low-bandwidth conversations, and then splits the left over bandwidth reasonably among the enduring conversations.
Look for a new set of Cisco and CompTIA enfranchisement communication questions soon!
