A company has two sites that host six cache web servers that are used to promote sales information.
Which feature on the NetScaler should an engineer enable to provide faster application performance and also provide additional capacity if the demand increases for one site?
A. Load balancingScenario: A NetScaler Engineer is working with a NetScaler appliance that has two network interface cards (NICs). The first NIC is placed on the DMZ network and the second NIC is on the internal network. The default route is configured to the gateway on the internal network. A virtual server is configured on the DMZ-network and the firewall on the DMZ is using network address translation (NAT) to allow external traffic to the virtual server.
When a user from the Internet attempts to connect to the NAT'd external address, the session never establishes. The engineer performs an nstrace and sees that the user's traffic hits the NetScaler. The engineer then discovers that the problem is an asymmetrical packet flow.
Which two settings could the engineer configure to resolve the issue? (Choose two.)
A. Link load balancing (LLB)Scenario: A NetScaler Engineer is configuring LACP (Link Aggregation Configuration Protocol) on the NetScaler. The engineer adds interface 10/3 and 10/4 to LA/1 (which already contains interfaces 10/1 and 10/2) and is configured for VLAN
500.
VLAN 100 is bound to interface 10/3 and VLAN 200 is bound to interface 10/4.
VLAN 500 is bound to channel LA/1.
Which VLAN is shown with a "show interface" command for interface 10/3?
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
172.10.0.30.
In order to complete this setup, the engineer should create a load-balancing virtual server with IP 172.10.0.30 on TD 3 and use __________. (Choose the correct option to complete the sentence.)
A. TD2 services as a backup virtual serverScenario: A network engineer has installed a NetScaler system into their corporate DMZ and would like to provide access to a web server on the internal LAN. The web server will be accessed by external users through the NetScaler. The
firewall administrator has opened the relevant ports required on the external and the internal firewall.
The engineer notices that the virtual server and services representing the web server are down and the internal web server does NOT appear accessible from the NetScaler.
What could be the cause of this?
A. USIP is not enabled.Which IP address type should be bound to a VLAN in order to isolate traffic to backend services?
A. Virtual IP (VIP)Scenario: A client connecting to an SSL virtual server receives the following error:
"Invalid Server Certificate The server certificate is invalid. Do you wish to accept this certificate and connect to the server anyway?"
What is a possible cause of this error message?
A. The private key is NOT password-protected.A NetScaler Engineer created an HTTP service and did NOT bind any monitors to the service. Which monitor will the NetScaler automatically bind to the HTTP service?
A. tcpA NetScaler Engineer plans to deploy a third-party application that will perform scheduled configuration auditing by using NITRO API with a REST interface. Which management protocol should the engineer enable to allow NITRO API access?
A. SSHScenario: A call center has deployed Access Gateway Enterprise to provide its employees with access to work resources from home. Due to the number of available licenses, only selected employees should access the environment remotely based on their user account information.
How could the engineer configure access to meet the needs of this scenario?
A. Configure a Pre-authentication Policy.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
