Q21. Scenario: A NetScaler Engineer has created a local account for a user according to the below configuration: add system user NSUser userpassword -timeout 900 add system group "NetScaler users" -timeout 900 add system cmdPolicy netscaler-users ALLOW "(^man.*)|(^show\\\\s+(?!system)(?!configstatus)(?!ns ns\\\\.conf)(?!ns savedconfig)(?!ns runningConfig)(?!gslb runningConfig)(?!audit messages)(?!techsupport).*)|(^stat.*)" bind system group "NetScaler users" -userName NSUser bind system group "NetScaler users" -policyName netscaler-users 100 The user is able to log on but is NOT able to execute certain commands. The engineer goes back and looks at the logs, and the following is displayed: Oct 6 13:34:15 <local0.info> 192.168.10.50 10/06/2014:13:34:15 GMT ns1 0-PPE-0 : CLI CMD_EXECUTED 4303 0 : User NSUser - Remote_ip 192.168.10.10 - Command "show ns runningConfig" - Status "ERROR: Not authorized to execute this command" Why is the command NOT working for the user?
A. cmdPolicy is NOT configured to allow the command
B. cmdPolicy should be set to DENY, instead of ALLOW
C. The user should be bound to the cmdPolicy netscaler-users
D. The priority of the cmdPolicy bound to the group "NetScaler users" should be higher
Q22. Which two of the following settings could be configured using a TCP profile that is bound to a service? (Choose two.)
A. TCP buffer size
B. Window scaling
C. TCP Server time-out values
D. Source IP for specific subnet
E. Allowed bandwidth throughput
F. Number of max concurrent TCP connections
Answer: A, B
Q23. Scenario: A NetScaler Engineer needs to enable access to a load-balancing virtual server from two customers that belong to different VLANs, VLAN500 and VLAN600. Each customer must access the services and servers specific to their VLAN and should never be able to reach another customer service or servers. Traffic Domain (TD) 1 has been created for VLAN500 and Traffic Domain (TD) 2 for VLAN600. Load-balancing services have also been created for each server on TD1 and TD2. The TD for the virtual server is TD 3 and IP address
184.108.40.206. In order to complete this setup, the engineer should create a load-balancing virtual server with IP 220.127.116.11 on TD 3 and use . (Choose the correct option to complete the sentence.)
A. TD2 services as a backup virtual server
B. TD1 and TD2 services on one virtual server C. TD1 and TD2 services on two virtual servers D. TD1 on one virtual server and TD2 on second
Q24. Scenario: A company is hosting an external, Internet-facing website that is load balanced by a NetScaler. The backend servers are on a 1 Gbps network and clients connect over 3G connections. The Server Administrator reviewed the performance metrics on the backend servers and noticed a lot of overall network retirements and retransmissions. Which NetScaler feature would help improve the network performance of the backend servers in this scenario?
C. TCP Buffering
D. Surge Protection
Q25. Which two content types are, by default, compressible content on the NetScaler? (Choose two.)
Answer: C, E
Q26. Which feature could a Network Engineer configure in order to restrict client connections to a specific bandwidth limit?
B. Rate Limiting
D. Filter Policies
Q27. Which setting would a NetScaler Engineer disable in order to stop the NetScaler from acting as a router for non-NetScaler owned IP addresses or entities?
A. Layer 2 mode
B. Layer 3 mode
C. MAC-based forwarding
D. Use Subnet IP (USNIP)
Q28. An engineer is checking that ports are configured correctly between the NetScaler system and a back-end web server. Which command should the engineer use to test that the web server is responding on port 80?
A. telnet webA.example.com 80
B. telnet webA.example.com:80
C. telnet webA.example.com port=80
D. telnet webA.example.com -port 80
Q29. Which two virtual servers could a NetScaler Engineer configure to redirect GET requests to application servers? (Choose two.)
A. Load balancing
D. Content switching
Answer: A, D
Q30. Scenario: A NetScaler Engineer has discovered that the object home.php is NOT found in the cache on the system. Below is the relevant configuration: add cache contentGroup cache_content_group_1 -relExpiry 0 add cache policy cache_pol_1 -rule "http.REQ.URL.CONTAINS(\\"home.php\\")" -action MAY_CACHE -storeInGroup cache_content_group_1 add cache policy cache_pol_2 -rule "http.REQ.METHOD.EQ(\\"GET\\")" -action NOCACHE add cache policy cache_pol_3 -rule "HTTP.RES.HEADER(\\"Set-Cookie\\").EXISTS" -action CACHE bind cache global cache_pol_1 -priority 90 -gotoPriorityExpression END -type REQ_OVERRIDE bind cache global cache_pol_2 -priority 100 -gotoPriorityExpression END -type REQ_OVERRIDE bind cache global cache_pol_3 -priority 100 -gotoPriorityExpression END -type RES_OVERRIDE The data from the client and the server are as following: GET /home.php HTTP/1.1
