Enterprise

Subnet

VLAN ID

User

NEW QUESTION 20
Which of the following is a host-centric overlay solution for a modern data center?

SPBM

TRILL

VXLAN

VPLS

Modern data center, traditional technologies are limiting the speed, flexibility, scalability, and manageability of application deployments. There is emerging interest in the industry in overlay technologies (such as MPLS, VXLAN, LISP…)

NEW QUESTION 21
What is the function of a Virtualized Services Gateway (VSG)?

To interconnect a VLAN network with a VXLAN network.

To interconnect multiple data centers.

To extend a data center to the internet.

To enable MPLS over GRE tunneling

NEW QUESTION 22
What statement is TRUE regarding multiple virtual IP addresses assigned to a single vPort?

The virtual IP addresses can be in a different subnet than the VM interface IP address.

All virtual IP addresses of a vPort must be in the same subnet.

One of the virtual IP addresses can be the same as the VM interface IP address.

Every virtual IP address must be associated with a virtual MAC, which differs from the VM interface
MAC address.

Explanation
If you have only one public IP address available, and you want to host multiple servers, use aVIP.

NEW QUESTION 23
What statement regarding active/standby VSD cluster is TRUE?

Both the primary and secondary cluster are running all VSD services.

XMPP connections to the secondary cluster are blocked.

The active/standby mode is also supported in standalone VSD.

VSP components (eg: VSCs) need reconfiguration after failover.

NEW QUESTION 24
What statement about statistics rules on Nuage VCS is FALSE?

Users can define statistics rules for domain/zones/subnets/vPorts. The rule applied to the most granular
object is the one used.

Statistics are collected in an Elasticsearch statistics engine and are aggregated over hours, days, and
months.

Statistics are pushed from VRS up to VSC, which in turn sends them to the VSD stats engine.

When a TCA threshlod is exceeded, an event is displayed in the UI and a message is sent on the JMS
bus.

NEW QUESTION 25
If we compare a Nuage Virtual Service Node to a physical service router, which module is VSC mapped to?

Switch fabric

Line card

CPU module

Internal clock

Explanation
The switching fabric is independent of the bus technology and infrastructure used to move data between nodes and also separate from the router. The term is sometimes used to mean collectively all switching hardware and software in a network.

NEW QUESTION 26
The ML2 plug-in is part of which OpenStack project?

Neutron

Ironic

Nova

Heat

NEW QUESTION 27
Refer to the diagram.

Which statement is describing a step incorrectly?

Step a, which consists of defining network domain and policy templates on VSD, must be performed first in all situations.

Step d, which refers to the VRS agent informing the VSC of the placement of a new VM, is triggered by step f in which the VM is instantiated on a hypervisor.

Step b, in which the VSC queries VSD on network service and policies required for a new VM, is triggered either by API calls from the CMS or by manual configuration.

Step e, in which the forwarding tables are deployed, consists of the VSC sending them not only to the VRS agent hosting the new VM, but to all applicable VRS agents.

NEW QUESTION 28
What statement about policy groups is FALSE?

Several vPorts ( in the same or different subnets) can be associated with one policy group.

One vPort can be associated with multiple policy groups.

For an ingress security policy, if a hardware endpoint policy group is chosen as the source, the destination must also be hardware endpoints.

The policy group is the syntactic equivalent of the security group used by cloud management systems.

NEW QUESTION 29
What statement regarding VSD user management is TRUE?

We can create CMS user groups for each enterprise.

Each enterprise user belongs to only one user group.

Open LDAP and Active Directory can be integrated into VSD.

LDAP integration is configured at the VSD global level, and it is not configurable enterprise.

Easy as adding them to a specific user group.

NEW QUESTION 30
When using a VXLAN gateway to connect VLAN-based equipment with VMS inside a VXLAN data center, what types of vPort can be used on the VSD GUI to connect those VLAN-based devices?

VM vPort and host

Host vPort and bridge vPort

Bridge V vport gateway vPort.

Gateway vport and VM vPort.

NEW QUESTION 31
Which four Openstack projects implement Nuage integration?

Keystone, Heat, Neutron, Nova

Ironic, Heat, Horizon, Neutron

Cinder, Horizon, Neutron, Nova

Ironic, Heat, Neutron, Nova

NEW QUESTION 32
What statement regarding VSC deployment is TRUE?

VSC can be deployed in standalone mode or in high-availability cluster mode.

VSC can only be installed as virtual machines.

VSC is based on SR OS, and thus can be integrated module on the 7750 SR.

XMPP is used to synchronize the active and standby VSCs.

NEW QUESTION 33
What use case does not apply in virtual machine migration?

Optimization of East-West traffic flows.

Maintenance and upgrading of the servers.

Avoidance of disaster caused by a power outage or hardware failure.

Entry saving by shutting sown under-utilized servers after moving all their VNs.

NEW QUESTION 34
What statement is TRUE regarding a redundant redirection target?

By default, high availability is enabled for all redirection target.

A redundant redirection target can have only 1 virtual IP.

We can associated at maximum 2 vPorts with a redundant redirection target.

Traffic will be redirected to all of the vPorts within a redundant redirection target.

NEW QUESTION 35
To auto-instantiate services on a 7750 DCI, which protocol needs to be enabled between the 7750 SR and VSD?

SNMP

Openflow

XMPP

BGP EVPN

Explanation/Reference:

NEW QUESTION 36
What statement correctly describes the difference between a managed Layer 2 domain and an undamaged
Layer 2 domain?

A managed L2 domain has one or more zones and each zone can have multiple subnets, each with its
own IP address pool, while an unmanaged L2 domain does not have zones or subnets.

Managed L2 domains can have overlapping IP address pools, while unmanaged L2 domains are not
allowed to have overlapping IP address pools.

In a managed L2 domain, Nuage VCS manages security policies, while in an unmanaged domain,
Nuage VCS cannot manage the security policies.

In a managed L2 domain, Nuage VCS performs DHCP and ARP proxy functions, while in an
unmanaged domain VCS has no visibility of IP addresses.

NEW QUESTION 37
Which statement correctly describes cloud computing?

Services are statically provisioned by a cloud service provider.

Services are offered as needed through the Internet.

SDN is the key enabler for cloud computing.

It provides convenient, permanent network access to a shared pool of computing resources.

Explanation
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of
configurable computing resources

NEW QUESTION 38
What statement regarding Openflow sessions in data center networks is TRUE?

By default, the Openflow session is established with TCP port 6633.

Openflow sessions run between VSCs.

Security is mandatory with SSL encryption.

Openflow sessions can be established over either the data plane or the management plane.

SSL (Secure Sockets Layer) is the standard security.

NEW QUESTION 39
What statement is TRUE regarding the security policies provided by Nuage VCS?

The match criteria in security policies can be based on MAC address, IP address and TCP/UDP port
number.

Each policy entry has an associated priority that defines the order in which policy entries are evaluated.

Ingress security policy controls the traffic flowing into the virtual machine.

The default ingress security policy allows all traffic to be forwarded.

NEW QUESTION 40
Which statement correctly describes cloud computing?

Services are statically provisioned by a cloud service provider.
