  A. Generator
  B. Cold site
  C. Redundant power supplies
  D. Uninterruptible power supply

  A. SNMP
  B. NX-API
  C. REST
  D. RESTCONF
  D. RESTCONF

  ---

  Explanation

  YANG (Yet another Next Generation) is a data modeling language for the definition of data sent over network management protocols such as the NETCONF and RESTCONF.

• Question 113:

  Which protocol is used by vmanage to push centralized policies to vsmart controllers?

  A. NETCONF
  B. TLS
  C. STUN
  D. OMP
  A. NETCONF

• Question 114:

  Which feature must be configured to allow packet capture over Layer 3 infrastructure'?

  A. VSPAN
  B. IPSPAN
  C. RSPAN
  D. ERSPAN
  D. ERSPAN

  ---

  Explanation

  Encapsulated remote SPAN (ERSPAN): encapsulated Remote SPAN (ERSPAN), as the name says, brings generic routing encapsulation (GRE) for all captured traffic and allows it to be extended across Layer 3 domains.

• Question 115:

  What happens to the signal strength of an RF signal due to wave spreading?

  A. The signal strength of the RF signal will fall off equally near the transmitter and also farther away
  B. The signal strength of the RF signal will fall off quickly near the transmitter but more slowly farther away
  C. The signal strength of the RF signal will fall off slowly near the receiver and more quickly farther away
  D. The signal strength of the RF signal will fall off slowly near the transmitter but more quickly farther away
  B. The signal strength of the RF signal will fall off quickly near the transmitter but more slowly farther away

• Question 116:

  DRAG DROP

  Drag and drop the characteristics from the left onto the corresponding switching architectures on the right.

  Select and Place:

  

  

• Question 117:

  A network engineer configures BGP between R1 and R2. Both routers use BGP peer group CORP and are set up to use MD5 authentication. This message is logged to the console of router R1:

  `May 5 39:85:55.469: %TCP-6-BADAUTH` Invalid MD5 digest from 10.10.10.1 (29832) to 10.120.10.1 (179) tebleid -0

  Which two configurations allow a peering session to form between R1 and R2? (Choose two.)

  A. R1(config-router)#neighbor 10.10.10.1 peer-group CORP R1(config-router)#neighbor CORP password Cisco
  B. R2(config-router)#neighbor 10.120.10.1 peer-group CORP R2(config-router)#neighbor CORP password Cisco
  C. R2(config-router)#neighbor 10.10.10.1 peer-group CORP R2(config-router)#neighbor PEER password Cisco
  D. R1(config-router)#neighbor 10.120.10.1 peer-group CORP R1(config-router)#neighbor CORP password Cisco
  E. R2(config-router)#neighbor 10.10.10.1 peer-group CORP R2(config-router)#neighbor CORP password Cisco
  A. R1(config-router)#neighbor 10.10.10.1 peer-group CORP R1(config-router)#neighbor CORP password Cisco
  B. R2(config-router)#neighbor 10.120.10.1 peer-group CORP R2(config-router)#neighbor CORP password Cisco

  ---

  Explanation

  The log is on R1.The question states the console output is from R1, which means that R1 is 10.120.10.1, and R2 is 10.10.10.1. If you missed that you may have assumed the reverse and picked DE.

• Question 118:

  Which characteristic applies to the Cisco SD-Access solution?

  A. Dynamic routing is used to discover and provision border and edge switches.
  B. The control plane is based on VXLAN.
  C. The data plane is based on VXLAN.
  D. GRE is used as the policy plane.
  C. The data plane is based on VXLAN.

  ---

  Explanation

  The correct answer is Option C. The data plane is based on VXLAN.

  Cisco SD-Access uses the following fabric architecture:

  Control plane: LISP

  Data plane: VXLAN

  Policy plane: Cisco TrustSec / Scalable Group Tags

  VXLAN is used to encapsulate and transport user traffic across the SD-Access fabric overlay. Therefore, the SD-Access data plane is based on VXLAN.

  Option A is incorrect because dynamic routing may be used in the underlay, but it does not discover and provision SD-Access border and edge nodes. Provisioning is handled through Cisco DNA Center / Cisco Catalyst Center.

  Option B is incorrect because the SD-Access control plane is based on LISP, not VXLAN.

  Option D is incorrect because the policy plane is based on TrustSec and Scalable Group Tags, not GRE.

• Question 119:

  Refer to the exhibit.

  

  Which EEM script generates a critical-level syslog message and saves a copy of the running configuration to the bootflash when an administrator saves the running configuration to the startup configuration?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 120:

  Refer to the exhibit.

  

  An engineer entered the command no spanning-tree bpduguard enable on interface Fa 1/0/7.

  What is the effect of this command on Fa 1/0/7?

  A. It remains in err-disabled state until the shutdown/no shutdown command is entered in the interface configuration mode.
  B. It remains in err-disabled state until the errdisable recovery cause failed-port-state command is entered in the global configuration mode.
  C. It remains in err-disabled state until the no shutdown command is entered in the interface configuration mode.
  D. It remains in err-disabled state until the spanning-tree portfast bpduguard disable command is entered in the interface configuration mode.
  A. It remains in err-disabled state until the shutdown/no shutdown command is entered in the interface configuration mode.

  ---

  Explanation

  Seems someone maybe trying to insert a switch into that port which sends bpdu packets. The port is configured to not allow this so it goes into an error disable mode and shuts the port down. You have to do a shut and no shut on the port to bring it back up. However, it may go down again if the device sending bpdu's is still active on the port.
