Company.com is planning for an HACMP cluster and wants to know more about the network requirements. The plan is to use IPAT via IP aliasing and heartbeating via IP aliasing to preserve the corporate IP addresses. Currently the customer uses a separate VLAN for each individual subnet.  Which statement best describes how HACMP co-exists with VLAN’s in this configuration？（）   

• A、 All subnets in use by HACMP must be in the same VLAN.
• B、 All subnets in sue by HACMP must be in a different VLAN.
• C、 HACMP does not support multiple subnets when using heartbeating via IP aliasing.
• D、 HACMP does not support the use of VLAN.

• B、Export polices can evaluate all routes
• C、Export polices can be applied to the forwarding table
• D、Export polices can be applied to interfaces

What does the Web Session Affinity feature of Active GridLink for RAC provide?（）

• A、It mandates that HTTP sessions must be stored in an Oracle RAC database for the highest  throughput and availability.
• B、It pins a connection to the thread associated with a web session such that subsequent  connection reservations are significantly faster.
• C、It stores a reference to the connection associated with an HTTP session in the session object.
• D、It allows developers to modify how their web application reserves and releases database  connections to allow enhanced performance.
• E、It provides improved performance by associating a database connection with an HTTP session.

Which statement describes VRRP object tracking?（）

• A、It monitors traffic flow and link utilization.
• B、It ensures the best VRRP router is the virtual router master for the group.
• C、It causes traffic to dynamically move to higher bandwidth links
• D、It thwarts man-in-the-middle attacks.

What is the command to configure RSVP to reserve up to one-tenth of a Gigabit link， but only allow each individual flow to use 1 MB/s？（）

• A、ip rsvp bandwidth 10000 1000
• B、ip rsvp bandwidth 100000 1
• C、ip rsvp bandwidth 10 1
• D、ip rsvp bandwidth 1000000 1000

第16题：

What is an advantage of the IntServ QoS model？（）

• A、 It supports admission control that allows a network to reject or downgrade new RSVP sessions if one of the interfaces in the path has reached the limit （that is， all reservable bandwidth is booked）.
• B、 RSVP signals QoS requests per individual flow. In the request the authorized user （authorization object） and needed traffic policy （policy object） are sent. The network can then provide best-effort delivery to these individual flows.
• C、 RSVP streamlines communication by making it unnecessary to inform network devices of flow parameters （IP addresses and port numbers）.
• D、 Because of the stateful RSVP architecture， continuous signaling does not have to occur.
• E、 The flow-based approach is scalable to large implementations， such as the public Internet， because RSVP tracks each individual flow.

第17题：

Which interface tunnel parameter allows an LSP to use a specified explicit route?（）

• A、path-option
• B、route-option
• C、explicit-path-option
• D、explicit-route-option

第18题：

Which two statements are true regarding routing policy processing?（）

• A、The Junos OS verifies the match criteria of each policy in order and performs the associated action when a match occurs.
• B、Policies are evaluated from right to left as displayed in the Junos OS configuration file.
• C、Polices are evaluated based on the order in which they are applied to a routing protocol.
• D、Policy processing stops once the last statement in the policy is evaluated.

第19题：

You are the network administrator for Your network consists of two Active Directory domains. Each department has its own organizational unit (OU) for departmental user accounts. Each OU has a separate Group Policy object (GPO) A single terminal server named TestKingTerm1 is reserved for remote users. In addition, several departments have their own terminal servers for departmental use. Your help desk reports that user sessions on TestKingTerm1 remain connected even if the sessions are inactive for days. Users in the accounting department report slow response times on their terminal server. You need to ensure that users of TestKingTerm1 are automatically logged off when their sessions are inactive for more than two hours. Your solution must not affect users of any other terminal servers. What should you do?（）

• A、For all accounting users, change the session limit settings.
• B、On TestKingTerm1, use the Terminal Services configuration tool to change the session limit settings.
• C、Modify the GPO linked to the Accounting OU by changing the session limit settings in user-level group polices.
• D、Modify the GPO linked to the Accounting OU by changing the session limit settings in computer-level group polices.
