(True or False) True False When setting up access and security, SSH credentials (keypairs) must be injected into images after they are launched with a script. (True or False) True False You can track monthly costs with metrics like: (choose all that apply) VCPU QoS Uptime Disks RAM The following OpenStack command-line clients are available. (choose all that apply) python-keystoneclient python-hypervisorclient python-imageclient python-cinderclient python-novaclient To install a client package the following command syntax is used: $ sudo pip install [--update] python-project client (True or False) True False To get a list of images in glance you can use the following command syntax: $ glance image-list True False When troubleshooting image creation you will need to look at which of the following log files for errors? (choose all that apply) Examine the /var/log/nova-api.log Examine the /var/log/nova-compute.log Examine the /var/log/nova-error.log Examine the /var/log/nova-status.log Examine the /var/log/nova-image.log To generate a keypair use the following command syntax: $ nova keypair-add --pub_key ~/.ssh/id_rsa.pub KEY_NAME True False When you want to launch an instance you can only do that from an image. (True or False) True False An instance has a Private IP address which has the following properties? (choose all that apply) Used for communication between instances VMware vShpere 4.1, update 1 or greater Stays the same, even after reboots Stays allocated, even if you terminate the instance To see the status of the Private IP addresses you use the following command: $ nova floating-ip-pool-list To start and stop and instance you can use the following options: (choose all that apply) Pause/Un-pause Suspend/Resume Reboot Evacuate Shutdown/Restart To create a network in OpenStack use the following command: $ neutron net-create net1 (True or False) True False Identity Service provides the following functions: (choose all that apply) Group policy objects Message queuing User management Publishing Service catalog The AMQP supports the following messaging bus options: (choose all that apply) ZeroMQ RabbitMQ Tibco Rendezvous IBM WebSphere Message Broker Qpid OpenStack uses the term tenant but in earlier versions it used the term customer. (True or False) True False Associate Training Guide, Controller Node Quiz Answers B (False) - you can manage images through only the glance and nova clients or the Image Service and Compute APIs. B (False) - Keypairs are SSH credentials that are injected into images when they are launched. For this to work, the image must contain the cloud-init package A, C, D, E - You can track costs per month by showing metrics like number of VCPUs, disks, RAM, and uptime of all your instances A, D, E - The following command-line clients are available for the respective services' APIs: cinder(python-cinderclient) Client for the Block Storage Service API. Use to create and manage volumes. glance(python-glanceclient) Client for the Image Service API. Use to create and manage images. keystone(python-keystoneclient) Client for the Identity Service API. Use to create and manage users, tenants, roles, endpoints, and credentials. nova(python-novaclient) Client for the Compute API and its extensions. Use to create and manage images, instances, and flavors. neutron(python-neutronclient) Client for the Networking API. Use to configure networks for guest servers. This client was previously known as neutron. swift(python-swiftclient) Client for the Object Storage API. Use to gather statistics, list items, update metadata, upload, download and delete files stored by the object storage service. Provides access to a swift installation for ad hoc processing. heat(python-heatclient) A (True) A (True) A, B B (False) - $ nova keypair-add KEY_NAME> MY_KEY.pem B (False) - you can launch and instance from an image or a volume A, B, C A, B, C, D A (True) C, E A, B, E B (False) - Because the term project was used instead of tenant in earlier versions of OpenStack Compute, some command-line tools use --project_id instead of --tenant-id or --os-tenant-id to refer to a tenant ID.
