• Question 142:

  An engineer must configure HSRP for VLAN 1000 on SW2. The secondary switch must immediately take over the role of active router If the interlink with the primary switch fails.

  Which command set completes this task?

  SW2(config)#track 1000 interface gigabitEthernet0/0 line-protocol

  SW2(config-track)#exit

  SW2(config)#interface vlan 1000

  SW2(config-if)#ip address 10.23.87.3 255.255.255.0

  A. SW2(config-if)# standby version 2 SW2(config-if)# standby 1000 ip 10.23.87.1 SW2(config-if)# standby 1000 priority 95 SW2(config-if)# standby 1000 preelept SW2(config-if)# standby 1000 track gigabitethernet0/0
  B. SW2(config-if)# standby 1000 ip 10.23.87.1 SW2(config-if)# standby 1000 priority 95 SW2(config-if)# standby 1000 preempt SW2(config-if)# standby 1000 track 1000
  C. SW2(config-if)# standby version 2 SW2(config-if)# standby 1000 ip 10.23.87.1 SW2(config-if)# standby 1000 priority 95 SW2(config-if)# standby 1000 preempt SW2(config-if)# standby 1000 track 1000
  D. SW2(config if)# standby version 2 SW2(config-if)# standby 1000 ip 10.23.87.1 SW2(config-if)# standby 1000 priority 95 SW2(config-if)# standby 1000 track 1000
  C. SW2(config-if)# standby version 2 SW2(config-if)# standby 1000 ip 10.23.87.1 SW2(config-if)# standby 1000 priority 95 SW2(config-if)# standby 1000 preempt SW2(config-if)# standby 1000 track 1000

• Question 143:

  You need to weigh the pros and cons of deploying a premise-based data center versus using a cloud-based data center deployment.

  What is an advantage of using a premise-based solution? (Choose two.)

  A. Lower application latency for end users
  B. Easily scalable
  C. Lower capital costs
  D. Reduced deployment times
  E. Increased control over the environment
  A. Lower application latency for end users
  E. Increased control over the environment

  ---

  Explanation

  AE sounds like the only two correct-ish answers in this one, but A is kinda debatable since especially with Work from home culture / VPN's, it doesn't really matter anymore since you'd always connect either to on-prem, or to a cloud environment.

• Question 144:

  Refer to the exhibit.

  

  After configuring the BGP network, an engineer verifies that the path between server1 and server2 is functional, why did RouterSF choose the route from RouterDAL instead of the route from RouterCHI?

  A. BGP is not running on RouterCHI
  B. The Router-ID for Router DAL is lower than Router-ID for RouterCHI
  C. There is a static route in RouterSF for 10.0.0.0/24
  D. The route from RouterDAL has a lower MED
  B. The Router-ID for Router DAL is lower than Router-ID for RouterCHI

  ---

  Explanation

  All things being the same, we see that DAL has the lower router ID. C does not make sense, as the med value is stripped when crossing AS's and is only useable for iBGP peers.

• Question 145:

  Which protocol is responsible for data plane forwarding in a Cisco SD-Access deployment?

  A. VXLAN
  B. IS-IS
  C. OSPF
  D. LISP
  A. VXLAN

  ---

  Explanation

  In SD-Access the control plane is based on LISP (Locator/ID Separation Protocol), the data plane is based on VXLAN (Virtual Extensible LAN), the policy plane is based on Cisco TrustSec, and the management plane is enabled and powered by Cisco DNA Center.

• Question 146:

  Which AP mode analyzes the spectrum to detect sources of interference?

  A. Monitor
  B. Rogue detector
  C. SE-Connect
  D. Sniffer
  C. SE-Connect

• Question 147:

  Which line must be added in the Python function to return the JSON object {"cat_9k": "FXS193202SE")?

  

  A. return (json.dumps({d['hostname']: d['serialNumber'] for d in json.loads(test_json)['response']}))
  B. return (json.dumps({for d in json.loads(test_json)['response']: d['hostname']: d['serialNumber']}))
  C. return (json.loads({d['hostname']: d['serialNumber'] for d in json.dumps(test_json)['response'}))
  D. return (json.loads({for d in json.dumps(test_json)['response']: d['hostname']: d['serialNumber']}))
  A. return (json.dumps({d['hostname']: d['serialNumber'] for d in json.loads(test_json)['response']}))

  ---

  Explanation

  json.loads = from json to python json.dumps = from python to json

• Question 148:

  An engineer must configure a GRE tunnel interface in the default mode. The engineer has assigned an IPv4 address on the tunnel and sourced the tunnel from an ethernet interface.

  Which additional configuration must be made on the tunnel interface?

  A. (config-if)#tunnel destination <ip address>
  B. (config-if)#keepalive <seconds retries>
  C. (config-if)#ip mtu <value>
  D. (config-if)#ip tcp adjust-mss <value>
  A. (config-if)#tunnel destination <ip address>

  ---

  Explanation

  A GRE interface definition includes:

  + An IPv4 address on the tunnel + A tunnel source + A tunnel destination

  Below is an example of how to configure a basic GRE tunnel:

  interface Tunnel 0 ip address 10.10.10.1 255.255.255.0 tunnel source fa0/0 tunnel destination 172.16.0.2

  In this case the "IPv4 address on the tunnel" is 10.10.10.1/24 and "sourced the tunnel from an Ethernet interface" is the command "tunnel source fa0/0". Therefore it only needs a tunnel destination, which is 172.16.0.2.

  Note: A multiple GRE (mGRE) interface does not require a tunnel destination address.

• Question 149:

  SIMULATION

  Guidelines

  This is a lab item in which tasks will be performed on virtual devices.

  1. Refer to the Tasks tab to view the tasks for this lab item.

  2. Refer to the Topology tab to access the device console(s) and perform the tasks.

  3. Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

  4. All necessary preconfigurations have been applied.

  5. Do not change the enable password or hostname for any device.

  6. Save your configurations to NVRAM before moving to the next item.

  7. Click Next at the bottom of the screen to submit this lab and move to the next question.

  8. When Next is clicked, the lab closes and cannot be reopened.

  Tasks

  Configure HSRP between DISTRO-SW1 and DISTRO-SW2 on VLAN 100 for hosts connected to ACCESS-SW1 to achieve these goals:

  1. Configure group number 1 using the virtual IP address of 192.168.1.1/24.

  2. Configure DlSTRO-SW1 as the active router using a priority value of 110 and DISTRO-SW2 as the standby router.

  3. Ensure that DISTRO-SW2 will take over the active role when DISTRO-SW1 goes down, and when DISTRO-SW1 recovers, it automatically resumes the active role.
