Tested Questions & Verified Answers | Latest Update |
Graded A+
1. What is the primary role of the Celiometer module in OpenStack?
Monitors the NFVI and helps identify bottlenecks and resource
optimization opportunities.
Manages user authentication and access control.
Facilitates network routing and switching.
Provides storage management for virtual machines.
2. In a scenario where a cloud service provider is experiencing limitations in
network scalability due to an increasing number of tenants, how could
implementing VXLAN help?
By allowing the provider to create virtual networks that can span
multiple physical networks, thus accommodating more tenants.
By reducing the number of physical servers needed for each tenant.
By enforcing stricter security protocols for each tenant's data.
By limiting the number of virtual machines each tenant can deploy.
3. What type of installation does the Ironic module in OpenStack facilitate?
Baremetal installation
Virtual machine installation
Container orchestration
Network configuration
4. In a scenario where multiple clients are using the same network resources,
how would implementing isolation improve the overall network
, performance?
By allowing all clients to share the same bandwidth equally.
By preventing resource contention and ensuring dedicated
bandwidth for each client.
By centralizing all network traffic through a single point.
By increasing the number of clients on the network.
5. Describe how the Congress module contributes to the overall functionality of
OpenStack.
The Congress module authenticates users in the OpenStack
environment.
The Congress module is responsible for data storage within
OpenStack.
The Congress module monitors network traffic in OpenStack.
The Congress module helps enforce and manage policies across
the OpenStack environment.
6. Which is true about a network host?
A host is an endpoint device that hosts or accesses a resource on
the network
A host is any computer or device that can be addressed on the
network.
A host is fundamentally the same thing as a network node
None of these are true of hosts
,7. If a company implements encryption as a security measure, what specific
benefit does it provide against cyber threats?
It increases the speed of network traffic.
It eliminates the need for firewalls.
It ensures all network devices are updated.
It protects sensitive data from being accessed by unauthorized
users.
8. What is the Log Forwarder?
A component of the DP or a Sensor that collects data from various
cloud sources, converts it to metadata, and forwards to the DP.
A component of the Windows Server Sensor that parses the Win Event
Log, converts it to metadata, and forwards to the DP.
A component of a Network Sensor or a Modular Sensor that
receives SYSLOG or other logging streams, converts them to
metadata, and forwards to DP.
A component of the Container Sensor that receives SYSLOG or other
logging streams, converts them to metadata, and forwards to DP.
9. Describe how NFV differs from traditional network management approaches.
NFV differs from traditional network management by utilizing
software to manage network services instead of relying on
dedicated hardware.
NFV is limited to a single type of network service.
NFV requires more physical devices than traditional methods.
NFV uses only hardware components for network management.
, 10. OpenStack Block Storage enables you to add extra block-level storage to
which component?
OpenStack Identity Manager
OpenStack Compute Instances
OpenStack System Architecture
OpenStack Object Storage
11. What does the term 'delivery' refer to in the context of the Cyber Kill Chain?
The initial reconnaissance of the target
The exploitation of a vulnerability
The installation of malware on the victim's system
Transmission of the attack to the intended victim(s)
12. A VPN is a/an:
Personal network for your only.
Communication tunnel between VLANs.
Encrypted connection across the Internet.
Virtual network within your local area network (LAN).
13. Which OpenStack unit allows different computer instances and storage
nodes to communicate?
Cinder
Neutron
Nova
Keystone
