Scenario:
CGE's CIO asks a Citrix Architect to design its Hypervisor networking solution. The storage team informs the architect that they have purchased a new 10GB iSCSI SAN array that the XenServer hosts will use for SAN storage. They would like the solution to meet all outlined requirements.
What should the architect recommend?
A. Each XenServer host should be configured with six 10GB network interfaces - four dedicated for storage traffic, one for management traffic, and one for guest virtual machine (VM) network traffic.
B. Each XenServer host should be configured with four 10GB network cards - two bonded for storage and management separated by separate VLAN, and two bonded for guest VM networks.
C. Each XenServer host should be configured with two bonded 10GB NICs for storage, management, and guest VM networking.
D. Each XenServer host should be configured with four 10GB NICS - two dedicated for storage, and two bonded for guest VM networks and management separated by VLAN.
Why would the architect choose active-active bonding when configuring network interfaces for guest VM networks?
A. It provides load balancing of VM traffic across multiple physical NIC interfaces at a per guest basis, and offers improved distribution of traffic across physical interfaces in the bond.
B. It sends all guest VM traffic in the bond to an active interface, which provides the best distribution of network load.
C. It uses a hashing algorithm, which provides better distribution of traffic across the interfaces in the bond.
Why is configuring an iSCSI LUN on a SAN the best design choice for vDisk storage?
A. It is the least expensive solution.
B. It is a highly scalable and resilient solution.
C. It creates the least amount of administrative overhead.
D. It reduces the system footprint.
Why is configuring CIFS on a NAS the best design solution for vDisk storage?
A. It is the least expensive solution.
B. It is a highly scalable and resilient solution.
C. It creates the least amount of administrative overhead.
D. It reduces the system footprint.
How should the architect configure high availability (HA) on a Windows File Server so that Provisioning Services always has access to the Provisioning Services images?
A. By using Distributed File Services
B. By using Clustered File Services
C. By using DNS Round Robin
D. By using XenServer with HA enabled
Why deploying two NetScaler appliances - one in the primary and one in the secondary datacenter, configured with a backup vServer the best design solution?
A. It allows end users to connect to their primary datacenter through a secure, reliable, and cost-effective solution.
B. It provides redundancy, while optimizing external WAN traffic.
C. It segments the Gateway and load-balancing features of the NetScaler appliances.
D. It allows for the expected expansion of remote access usage and provides SSL VPN functionality for future needs.
Why is creating six NetScaler virtual servers in HA pairs, configured with the subnets of the three sites and binded to redirection policies, the best design solution?
A. It provides intrasite redundancy in case of appliance failures, while enhancing performance through an active/active configuration.
B. It provides redundancy in case of site failures, while optimizing external WAN traffic.
C. It protects against WAN failures and connects end users to their home datacenter.
D. It allows for the expected expansion of remote access usage and provides functionality for future needs.
146 of 254 Why is deploying four NetScaler appliances - two in the primary and two in the secondary data center with four NetScaler virtual servers for each appliance binded to a session policy, the best remote access design?
A. It allows end users to connect to their primary datacenter through a secure, reliable, and cost-effective solution.
B. It provides redundancy, while optimizing external WAN traffic.
C. It segments the Gateway and load-balancing features of the NetScaler appliances.
D. It allows for the expected expansion of remote access usage and provides SSL VPN functionality for future needs.
Why is configuring regional shared storage locations on a CIFS server using DNS Round Robin the best design choice for vDisk storage?
A. It is the least expensive solution.
B. It is a highly scalable and resilient solution.
C. It creates the least amount of administrative overhead.
D. It reduces the system footprint.
Scenario:
Each XenServer host is configured with two bonded 10GB NICs for storage, management, and guest VM networking. The CIO would like to see network traffic distributed across all links to maximize the utilization of each link. All switches support 802.3ad and adaptive load balancing.
How should the architect configure XenServer?
A. Using active-active bonding
B. Using active-passive bonding
C. Using XenSever MPIO redundancy
D. Using LACP bonding
