Question 1

What is a benefit of deploying an on-premises infrastructure versus a cloud infrastructure deployment?
A) ability to quickly increase compute power without the need to install additional hardware
B) less power and cooling resources needed to run infrastructure on-premises
C) faster deployment times because additional infrastructure does not need to be purchased

Question 9

Which LISP device is responsible for publishing EID-to-RLOC mappings for a site?
A) ETR
B) MR
C) ITR
D) MS

Accepted Answer

The Egress Tunnel Router (ETR) is responsible for publishing Endpoint Identifier (EID) to Routing Locator (RLOC) mappings for a site in LISP (Locator/ID Separation Protocol).

Question 10

On which protocol or technology is the fabric data plane based in Cisco SD-Access fabric?
A) VXLAN
B) LISP
C) Cisco TrustSec
D) IS-IS

Accepted Answer

The fabric data plane in Cisco SD-Access is based on VXLAN (Virtual Extensible LAN), which is used for network virtualization and to extend Layer 2 networks over Layer 3 infrastructure.

Question 11

What does this EEM applet event accomplish? "event snmp oid 1.3.6.1.3.7.6.5.3.9.3.8.7 get-type next entry-op gt entry-val 75 poll-interval 5"
A) Upon the value reaching 75%, a SNMP event is generated and sent to the trap server.
B) It reads an SNMP variable, and when the value exceeds 75%, it triggers an action.
C) It issues email when the value is greater than 75% for five polling cycles.
D) It presents a SNMP variable that can be interrogated.

Accepted Answer

The event monitors an SNMP OID and triggers an action when the value exceeds 75%.

Question 12

Which method displays text directly into the active console with a synchronous EEM applet policy?
A) event manager applet boom event syslog pattern 'UP' action 1.0 syslog priority direct msg 'logging directly to console'
B) action 1.0 gets 'logging directly to console'
C) action 1.0 string 'logging directly to console'
