5 Answer: A QUESTION NO: 8 A site has six members in a pool. All of the servers have been designed, built, and configured with the same applications. It is known that each client's interactions vary significantly and can affect the performance of the servers. If traffic should be sent to all members on a regular basis, which load-balancing method is effective if the goal is to maintain a relatively even load across all servers? A. Priority B. Observed C. Round Robin D. Ratio Member Answer: B QUESTION NO: 9 Which statement accurately describes the relation between the two load-balancing modes specified as "member" and "node"? A. There is no difference; the two terms are referenced for backward compatibility purposes. B. When the load-balancing choice references "node", priority group activation is unavailable. C. Load-balancing options referencing "nodes" are available only when the pool members are defined for the "any" port. D. When the load-balancing choice references "node", the address' parameters are used to make the load-balancing choice rather than the member's parameters. Answer: D QUESTION NO: 10 Which two properties can be assigned to a pool? (Choose two.) A. ratio values B. priority values C. health monitors D. connection limits E. load-balancing mode Answer: C, E

6 QUESTION NO: 11 Click the Exhibit button. A virtual server is defined per the charts. The last five client connections were to members C, D, A, B, B. Given the conditions shown in the exhibit, if a client with IP address opens a connection to the virtual server, which member will be used for the connection? A :80 B :80 C :80 D :80 E :80 Answer: B QUESTION NO: 12 Which two can be a part of a pool's definition? (Choose two.) A. rule(s) B. profile(s) C. monitor(s) D. persistence type E. load-balancing method

7 Answer: C, E QUESTION NO: 13 A site would like to ensure that a given server's IP address is reachable prior to sending it client traffic. Which monitor template would be the simplest to use? A. TCP B. PING C. ICMP D. HTTP E. SNMP Answer: C QUESTION NO: 14 The current status of a given pool member is nknown? Which condition could explain that state? A. The member has no monitor assigned to it. B. The member has a monitor assigned to it and the most recent monitor was successful. C. The member has a monitor assigned to it and the monitor did not succeed during the most recent timeout period. D. The member's node has a monitor assigned to it and the monitor did not succeed during the most recent timeout period. Answer: A QUESTION NO: 15 When defining a monitor based on the HTTP template, which two options can be specified? (Choose two.) A. Send string B. Server name C. Timeout value D. Pool association E. Pool member association Answer: A, C QUESTION NO: 16 When configuring a pool member's monitor, which three association options are available? (Choose three.)

8 A. inherit the pool's monitor B. inherit the node's monitor C. configure a default monitor D. assign a monitor to the specific member E. do not assign any monitor to the specific member Answer: A, D, E QUESTION NO: 17 A monitor has been defined using the HTTP monitor template. The send and receive string were customized, but all other settings were left at their defaults. Which resources can the monitor be assigned to? A. any pool B. any node C. any virtual server D. only specific pool members Answer: A QUESTION NO: 18 A site is load-balancing to a pool of web servers. Which statement is true concerning BIG-IP's monitor's ability to verify whether the web servers are functioning properly or not? A. Web server monitors can test the content on any page on the server. B. Web server monitors always verify the contents of the index.html page. C. Web server monitors can test whether the server's address is reachable, but cannot test a page's content. D. Web server monitors can test the content of static web pages, but cannot query pages that would require the web server to dynamically find content. Answer: A QUESTION NO: 19 You need to terminate client SSL traffic at the BIG-IP and re-encrypt it after using an irule to choose a pool to process the data. Which two are profile types that would normally be associated with such a virtual server? (Choose two.) A. FTP B. UDP C. HTTPS D. ClientSSL

9 E. ServerSSL Answer: D, E QUESTION NO: 20 When can a single virtual server be associated with multiple profiles? A. Never. Each virtual server has a maximum of one profile. B. Often. Profiles work on different layers and combining profiles is common. C. Rarely. One combination, using both the TCP and HTTP profile does occur, but it is the exception. D. Unlimited. Profiles can work together in any combination to ensure that all traffic types are supported in a given virtual server. Answer: B QUESTION NO: 21 You need to terminate client SSL traffic at the BIG-IP and also to persist client traffic to the same pool member based on a BIG-IP supplied cookie. Which four are profiles that would normally be included in the virtual server's definition? (Choose four.) A. TCP B. HTTP C. HTTPS D. ClientSSL E. ServerSSL F. Cookie-Based Persistence Answer: A, B, D, F QUESTION NO: 22 You have created a custom profile named TEST2. The parent profile of TEST2 is named TEST1. If additional changes are made to TEST1, what is the effect on TEST2? A. All changes to TEST1 are propagated to TEST2. B. Some of the changes to TEST1 may propagate to TEST2. C. Changes to TEST1 cannot affect TEST2 once TEST2 is saved. D. When TEST1 is changed, the administrator is prompted and can choose whether to propagate changes to TEST2.

10 Answer: B QUESTION NO: 23 Why is persistence an important feature of a load-balancing product? A. Persistence is only important when load-balancing HTTP applications. B. Client performance is enhanced when clients are sent to the same server over and over again. C. Some applications behave better when clients return to the same server rather than any server in the pool. D. Persistence features allow clients to bypass security features and therefore decrease client response time. Answer: C QUESTION NO: 24 Click the Exhibit button. A virtual server is defined using a source-address based persistence profile. The last five connections were A, B, C, A, C. Given the conditions shown in the exhibit, if a client with IP address opens a connection to the virtual server, which member will be used for the connection?
