Scenario: A Citrix Architect has set up NetScaler MPX devices in high availability mode with version 12.0.53.13 nc. These are placed behind a Cisco ASA 5505 Firewall. The Cisco ASA Firewall is configured to block traffic using access
control lists. The network address translation (NAT) is also performed on the firewall.
The following requirements were captured by the architect during the discussion held as part of the NetScaler security implementation project with the customer's security team:
The NetScaler MPX device:
1.
should monitor the rate of traffic either on a specific virtual entity or on the device. It should be able to mitigate the attacks from a hostile client sending a flood of requests. The NetScaler device should be able to stop the HTTP, TCP, and DNS based requests.
2.
needs to protect backend servers from overloading.
3.
needs to queue all the incoming requests on the virtual server level instead of the service level.
4.
should provide protection against well-known Windows exploits, virus-infected personal computers, centrally managed automated botnets, compromised webservers, known spammers/hackers, and phishing proxies.
5.
should provide flexibility to enforce the decided level of security check inspections for the requests originating from a specific geolocation database.
6.
should block the traffic based on a pre-determined header length, URL length, and cookie length. The device should ensure that characters such as a single straight quote ("); backslash (\); and semicolon (;) are either blocked, transformed, or dropped while being sent to the backend server.
Which security feature should the architect configure to meet these requirements?
A. Global Server Load balancing with Dynamic RTTScenario: A Citrix Architect needs to deploy SAML integration between NetScaler (Identity Provider) and ShareFile (Service Provider). The design requirements for SAML setup are as follows:
1.
NetScaler must be deployed as the Identity Provider (IDP).
2.
ShareFile server must be deployed as the SAML Service Provider (SP).
3.
The users in domain workspacelab.com must be able to perform Single Sign-on to ShareFile after authenticating at the NetScaler.
4.
The User ID must be UserPrincipalName.
5.
The User ID and Password must be evaluated by NetScaler against the Active Directory servers SFO-ADS-001 and SFO-ADS-002.
6.
After successful authentication, NetScaler creates a SAML Assertion and passes it back to ShareFile.
7.
Single Sign-on must be performed.
8.
SHA 1 algorithm must be utilized.
The verification environment details are as follows:
1.
Domain Name: workspacelab.com
2.
NetScaler AAA virtual server URL https://auth.workspacelab.com
3.
ShareFile URL https://sharefile.workspacelab.com
Which SAML IDP action will meet the design requirements?
A. add authentication samIIdPProfile SAMI-IDP -samISPCertName Cert_1 -samIIdPCertName Cert_2 -assertionConsimerServiceURL “https://auth.workspacelab.com/samIIssueName auth.workspacelab.com -signatureAlg RSA-SHA256digestMethod SHA256-encryptAssertion ON -serviceProviderUD sharefile.workspacelad.comWhich NetScaler Management and Analytics System (NMAS) utility can a Citrix Architect utilize to verify the configuration template created by the NMAS StyleBook, before actually executing it on the NetScaler?
A. Dry RunWhich encoding type can a Citrix Architect use to encode the StyleBook content, when importing the StyleBook configuration under source attribute?
A. HexScenario: A Citrix Architect needs to configure a full VPN session profile to meet the following requirements:
1.
Users should be able to send the traffic only for the allowed networks through the VPN tunnel.
2.
Only the DNS requests ending with the configured DNS suffix workspacelab.com must be sent to NetScaler Gateway.
3.
If the DNS query does NOT contain a domain name, then DNS requests must be sent to NetScaler gateway. Which settings will meet these requirements?
A. Split Tunnel to OFF, Split DNS BothA Citrix Architect needs to configure advanced features of NetScaler by using StyleBooks as a resource in the Heat service.
What is the correct sequence of tasks to be completed for configuring NetScaler using the Heat stack?
A. 1. Install NetScaler Bundle for OpenStack 2. Deploy the Heat stack 3. Register OpenStack with NMAS 4. Add NetScaler instances (Optional) 5. Prepare the HOT by using the NetScaler heat resources and NetScaler Network Resource 6. Create service packages (Add OpenStack tenants)Which step does a Citrix Architect need to ensure during the Define phase when following the Citrix Methodology?
A. Testing steps were integrated.Scenario: Based on a discussion between a Citrix Architect and team of Workspacelab has been created across three (3) sites.
They captured the following requirements during the design discussion held for NetScaler design projects:
1.
All three (3) Workspacelab sites (DC, NDR, and DR) will have similar NetScaler configuration and design.
2.
Both external and internal NetScaler MPX appliances will have Global Server Load balancing (GSLB) configured and deployed in Active/Passive mode.
3.
GSLB should resolve both A and AAA DNS queries.
4.
In the GSLB deployment, the NDR site will act as backup for the DC site. whereas the DR site will act as backup for the NDR site.
5.
When the external NetScaler replies to DNS traffic coming in through Cisco Firepower IPS, the replies should be sent back through the same path.
6.
On the internal NetScaler, both front-end VIP and back-end SNIP will be part of the same subnet.
7.
USIP is configured on the DMZ NetScaler appliances.
8.
The external NetScaler will act default gateway for back-end servers.
9.
All three (3) sites (DC, NDR, and DR) will have two (2) links to the Internet from different service providers configured in Active/Standby mode.
Which design decision must the architect make to meet the design requirements above?
A. Interface 0/1 must be used for DNS traffic.For which three reasons should a Citrix Architect perform a capabilities assessment when designing and deploying a new NetScaler in an existing environment? (Choose three.)
A. Understand the skill set of the company.A Citrix Architect needs to make sure that maximum concurrent AAA user sessions are limited to 4000 as a security restriction.
Which authentication setting can the architect utilize to view the current configuration?
A. Global Session SettingsNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
