Free Cisco ENCOR 350-401 MCQ Question and Answers

Question 1

What are the primary advantages of hosting an application on the cloud?

Accepted Answer

Scalability

Answer

Scalability is the key advantage of installing an application in the cloud. On-premises installations need more hardware to scale up while cloud deployments can swiftly scale up or down to suit the demands of an application.

Question 2

Wireless LAN (WLAN) communication is done using a technique called orthogonal frequency division multiplexing (OFDM). Which three WLAN protocols among the following support OFDM?

Accepted Answer

all of the above

Answer

Both 802.11b and 802.11g feature Direct-Sequence Spread Spectrum (DSSS). 802.11a, 802.11g, and 802.11n all enable orthogonal frequency division multiplexing (OFDM). Keep in mind that 802.11g can support DSSS or OFDM. Using a collection of symbols referred to as "chips," DSSS modulates data over a wide frequency range. Because a chip lasts less time than a bit, chips are transmitted more quickly than actual data. These chips additionally encrypt what seems to be random data in addition to the data that will be transferred. In spite of the fact that both parties to a DSSS communication are aware of which chips represent valid data and which do not if a third party were to intercept a DSSS transmission, it would be challenging for them to eavesdrop on the information because they would not be able to quickly identify which chips contained valid bits. OFDM employs a relatively moderate modulation rate for its symbols compared to DSSS's high modulation rate. OFDM is able to sustain high data rates thanks to its slower modulation rate and the simultaneous delivery of data over 52 data streams.

Question 3

What is the proper mapping between IP Prec 4's Flash Override and DSCP Codepoint?

Accepted Answer

AF41, AF42, AF43

Answer

The only response that exclusively maps to Flash Override is AF41, AF42, and AF43.

Question 4

Which levels of logging are turned on by default?

Accepted Answer

0 - 7

Answer

Debugs are only logged when they are activated with a debug command, however, the console, vty lines, and buffer will log all messages from all severity (logging) levels by default.

Question 5

The orchestrator is known as __________________ in Cisco's Enterprise NFV.

Accepted Answer

Cisco DNA Center

Answer

The VNF administration and NFV orchestration capabilities are provided by Cisco DNA Center. The deployment of virtualized network services made up of numerous VNFs can be easily automated. No longer included in the Enterprise NFV solution are APIC-EM and ESA.
