Demo Questions

Question 1
What information is included in the VTEP (virtual tunnel endpoint) forwarding table? 
  1. The remote VM IP addresses, the VXLAN ID (VNI) and the remote VTEP.
  2. The remote VM MAC addresses, the VXLAN ID (VNI) and the remote VTEP.
  3. The remote VM IP addresses, the VXLAN ID (VNI) and the local VTEP.
  4. The remote VM MAC addresses, the VXLAN ID (VNI) and the local VTEP.
Correct answer: A
Explanation:
IP address is the remote VTEP IP address or the IP Multicast group address Reference: https://sites.google.com/site/amitsciscozone/home/data-center/vxlan

Question 2
What statement about virtual switches is FALSE?
  1. A virtual switch is typically implemented within the hypervisor so that the network is extended onto the server.
  2. Virtual switches are VLAN capable.
  3. Typically, virtual switches are as capable as physical switches, eg: LAG, hardware-based QoS.
  4. If a virtual switch is not on the hypervisor, all traffic will go out of the physical NIC.
Correct answer: D
Question 3
What is NOT a requirement for modern data center networks to facilitate cloud computing?
  1. Multi-tenancy
  2. Network automation
  3. Virtual machine live migration
  4. Network function virtualization
Correct answer: D
Question 4
What statement regarding active/standby VSD cluster is TRUE?
  1. Both the primary and secondary cluster are running all VSD services.
  2. XMPP connections to the secondary cluster are blocked.
  3. The active/standby mode is also supported in standalone VSD.
  4. VSP components (eg: VSCs) need reconfiguration after failover.
Correct answer: C
Question 5
What function is NOT supported on the Nuage 7850 VSG?
  1. Hardware VXLAN/VLAN gateway
  2. Cloud orchestration
  3. Top of Rack switch/Leaf router
  4. VSC functionality 
Correct answer: B
Question 6
What statement regarding VSD user management is TRUE?
  1. We can create CMS user groups for each enterprise.
  2. Each enterprise user belongs to only one user group.
  3. Open LDAP and Active Directory can be integrated into VSD.
  4. LDAP integration is configured at the VSD global level, and it is not configurable enterprise.
Correct answer: B
Explanation:
Easy as adding them to a specific user group. Reference: https://docs.adobe.com/content/help/en/target/using/administer/manage-users/enterprise/property-channel.html

Question 7
What statement regarding the VRS-G is FALSE?
  1. The VRS-G is the software VXLAN/VLAN gateway of the Nuage VCS solution.
  2. The VRS-G is deployed on a hypervisor, following the same deployment requirements as a regular VRS.
  3. Virtual machines created on the hypervisor are attached to access ports on VRS-G.
  4. The network ports on VRS-G point towards the Nuage overlay VXLAN network.
Correct answer: B
Explanation:
This permits the bridging of the hypervisor-focused overlay networking and physical devices in the data center. Reference: https://jujucharms.com/nuage-vrsg/

Question 8
What is NOT a function of VRS? 
  1. VxLAN tunneling
  2. Detecting VM events
  3. DHCP and ARP proxy
  4. Libvirtd
Correct answer: B
Question 9
Which protocol is used for VSC federation?
  1. BGP VPN-IPv4
  2. BGP EVPN
  3. Openflow
  4. XMPP
Correct answer: C
Explanation:
The VSC uses standard protocols to peer with existing networks, allowing it to discover full network topology and reachability. Through Openflow, it distributes relevant switching and routing information to hypervisors within the virtualized datacenter network.   Reference: http://www.nuagenetworks.net/wp-content/uploads/2015/08/NuageNetworks-Architecture-White-Paper.pdf

Question 10
Refer to the diagram. 
  
What is the correct sequence of events for a VM to be instantiated, and for its required network connectivity to be created with the Nuage VCS solution? 
a. Network domain and policy templates are defined on VSD. 
b. VSC queries VSD on network service and policies. 
c. VSD provides VSC with network service and policies. 
d. VRS agent informs VSC of the new VM placement. 
e. VSC deploys policy to applicable VRS agents. 
f. VM instantiated on the hypervisor.
  1. a->b->c->d->e->f
  2. a->b->c->f->d->-e
  3. a->f->d->b->c->-e
  4. f->d->b->a>c->-e
