• Question 455:

  An engineer must configure Interface and sensor monitoring on a router. The NMS server is located in a trusted zone with IP address 10.15.2.19. Communication between the router and the NMS server must be encrypted and password-

  protected using the most secure algorithms. Access must be allowed only for the NMS server and with the minimum permission levels needed.

  Which configuration must the engineer apply?

  A. ip access-list extended nms permit 1 host 10.15.2.19 any snmp-server view ro internet included snmp-server view ro ifEntry included snmp-server group nms v3 priv notify ro access nms snmp-server user user1 nms v3 encrypted auth md5 Password1 pri 3des Password123
  B. ip access-list standard nms permit 10.15.2.19 0.0.0.0 snmp-server view ro iso included snmp-server view ro ifEntry included snmp-server group nms v3 priv read ro access nms snmp-server user user1 nms v3 auth sha Password1 pri aes 256 Password123
  C. ip access-list standard nms permit 10.15.2.19 0.0.0.0 snmp-server view rw iso included snmp-server view rw ifEntry included snmp-server group nms v3 auth write rw access nms snmp-server user user1 nms v3 auth des Password1 pri des Password123
  D. ip access-list standard nms permit 10.15.2.19 255.255.255.255 snmp-server view ro iso included snmp-server view ro ifEntry included snmp-server group nms v3 priv read ro access nms snmp-server user user1 nms v3 auth 3des Password1 pri aes 192 Password123
  B. ip access-list standard nms permit 10.15.2.19 0.0.0.0 snmp-server view ro iso included snmp-server view ro ifEntry included snmp-server group nms v3 priv read ro access nms snmp-server user user1 nms v3 auth sha Password1 pri aes 256 Password123

• Question 456:

  Which configuration enables a successful login?

  A. R1#aaa new-model aaa authorization exec default local enable aaa admin privilege 15
  B. R1#username admin privilege 15 aaa authorization exec default local netconf-yang
  C. R1#netconf-yang username admin privilege 15 secret cisco123 aaa new-model aaa authorization exec default local
  D. R1#username admin privilege 15 aaa authorization exec default local
  C. R1#netconf-yang username admin privilege 15 secret cisco123 aaa new-model aaa authorization exec default local

• Question 457:

  Which technology uses network traffic telemetry, contextual information, and file reputation to provide insight into cyber threats?

  A. threat defense
  B. security services
  C. security intelligence
  D. segmentation
  A. threat defense

  ---

  Explanation

  The initial version of the Cisco Cyber Threat Defense solution was introduced in 2013, with a Cisco Validated Design (CVD) to bring together NetFlow telemetry from the Cisco network infrastructure, the Cisco Identity Services Engine (ISE) for user and device identity, and the StealthWatch System through a partnership with Lancope, Inc. to provide network behavior analysis and threat detection in the interior of the network.

• Question 458:

  Which statements are used for error handling in Python?

  A. try/catch
  B. try/except
  C. block/rescue
  D. catch/release
  B. try/except

  ---

  For example:

  try:

  print 1/0

  except ZeroDivisionError:

  print 'Error! We cannot divide by zero!!!'

• Question 459:

  What does the Cisco WLC Layer 3 roaming feature allow clients to do?

  A. maintain their IP address when roaming to an AP or controller with a different client VLAN assignment
  B. maintain their connection between APs even when the AP management VLANs are different
  C. maintain their connection even if the client IP address changes when roaming
  D. roam seamlessly between controllers even when the controller management VLANs are different
  A. maintain their IP address when roaming to an AP or controller with a different client VLAN assignment

  ---

  Explanation

  When a client initiates an L3 intercontroller roam, the two controllers involved can compare the VLAN numbers that are assigned to their respective WLAN interfaces If the two VLAN IDs differ, the controllers arrange a Layer 3 roam (also known as a local-to-foreign roam) that will allow the client to keep using its IP address.

• Question 460:

  What is the result of this Python code?

  >>> (3 * 5) % 2

  A. 1
  C. 7
  D. 7.5
  A. 1
