• Question 171:

  When a network engineer logs onto a new NetScaler device in the London datacenter, data output indicates that the device is NOT configured for the local time. How can the network engineer synchronize the correct time with an NTP server in the local data center?

  A. Configure the correct time from the GUI and restart.
  B. Modify the ntp.conf and rc.netscaler files and restart.
  C. Logon using the nsrecover/nsroot credentials and restart.
  D. Configure the NetScaler as a secondary NTP server and restart.
  B. Modify the ntp.conf and rc.netscaler files and restart.

• Question 172:

  Scenario: NetScaler is configured with a Subnet IP (SNIP) 192.168.1.10/24 on VLAN 1 and a SNIP 172.168.1.50/24 on VLAN 100.

  VLAN 100 has been properly associated with interface 1/1 and SNIP 172.168.1.50.

  A user on VLAN 100 is attempting to access a virtual server on 192.168.1.25 and NOT getting a response.

  After troubleshooting the network, an engineer identifies that asymmetric packet flows are NOT using the right interfaces on the return path to the client.

  Which NetScaler setting must be enabled to avoid this behavior?

  A. Layer 3 Mode
  B. Layer 2 Mode
  C. Direct Route Advertisement
  D. MAC-based forwarding (MBF)
  D. MAC-based forwarding (MBF)

• Question 173:

  Scenario: An organization has a fair usage policy that limits each customer to a maximum of five active connections in any given second. A NetScaler Engineer is given the task of implementing the requirements to enforce a policy using the Rate Limiting feature on NetScaler.

  Which commands should the network engineer execute to create a proper selector and limit identifier that fulfills the policy requirement?

  A. add stream selector API_selector CLIENT.IP.SRC add ns limitIdentifier API_limitidf -threshold 5 -mode CONNECTION -timeslice 1000 selectorName API_selector
  B. add stream selector API_selector HTTP.REQ.URL add ns limitIdentifier API_limitidf -threshold 5 -mode CONNECTION -timeslice 1000 selectorName API_selector
  C. add stream selector API_selector HTTP.REQ.URL add ns limitidentifier limit_req -mode request_rate -limitType smooth -timeslice 1000 -Threshold 5 selectorName API_selector
  D. add stream selector API_selector CLIENT.IP.SRC add ns limitidentifier limit_req -mode request_rate -limitType smooth -timeslice 1000 -Threshold 5 selectorName API_selector
  A. add stream selector API_selector CLIENT.IP.SRC add ns limitIdentifier API_limitidf -threshold 5 -mode CONNECTION -timeslice 1000 selectorName API_selector

• Question 174:

  Scenario: A NetScaler Engineer creates a new HTTP VServer using the following command:

  add lb vserver lb_test HTTP 172.20.10.85 80 -lbMethod LEASTCONNECTION -persistencetype COOKIEINSERT -timeout 0 -authentication ON -cacheable YES

  During testing, the engineer notices a cookie named NSC_iuuq2 with a value of:

  ffffffff020a1d1545525d5f4f58455e445a4a423660

  What is the purpose of this cookie?

  A. It indicates that the client has been authenticated.
  B. It indicates that the client has NOT been authenticated.
  C. It is used for persistence, describing only the VServer ID and Service IP.
  D. It is used for persistence, describing the VServer ID, Service IP and Service Port.
  D. It is used for persistence, describing the VServer ID, Service IP and Service Port.

• Question 175:

  A network engineer needs to upgrade both appliances of a High Availability (HA) pair. In which order should the network engineer upgrade the appliances?

  A. Disable high availability and upgrade one node at a time.
  B. Upgrade the primary node first without disabling high availability.
  C. Upgrade the secondary node first without disabling high availability.
  D. Perform the upgrade simultaneously without disabling high availability.
  C. Upgrade the secondary node first without disabling high availability.

• Question 176:

  What are two valid ways of checking that a back-end web server is reachable from the NetScaler SNIP address using port 80? (Choose two.)

  A. Run traceroute.
  B. Run telnet using the -srcip option.
  C. Bind a DNS monitor to a service group containing the web server.
  D. Bind a HTTP monitor to a service group containing the web server.
  E. Run the ping command between the NetScaler and the web server.
  B. Run telnet using the -srcip option.
  D. Bind a HTTP monitor to a service group containing the web server.

• Question 177:

  Scenario: A network engineer has created and bound an UDP-ECV monitor to identify the status of a UDP service. However, no matter what the response is, the service is always marked as UP. A possible cause of this behavior is that the network engineer __________. (Choose the correct option to complete the sentence.)

  A. forgot to add a receive string
  B. added the string ns_true as receive string
  C. added a string that is invalid and thus skipped
