220-1101 Which Command Should the Administrator Use Practice Questions

Common Traps on Which Command Should the Administrator Use Practice Questions

·Separate verification commands from configuration commands.
·Read whether the question asks to identify, verify, fix, permit or deny.
·Small command keywords often change the correct answer.

Sample Questions

A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?

Explanation: The workstation is assigned to VLAN 10 via the switch port configuration, but the default gateway is on a different VLAN (20). Without proper inter-VLAN routing (e.g., a router-on-a-stick with ACLs permitting traffic between VLANs), devices in VLAN 10 cannot reach the gateway on VLAN 20. The DHCP server provided an IP within VLAN 10's subnet, which is correct for that VLAN, but the gateway is in another subnet. The switch port VLAN assignment is the root cause; it should be on VLAN 20 to match the gateway, or inter-VLAN routing must be configured correctly.

A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?

Explanation: This scenario requires a balance between control and reduced overhead. Infrastructure as a Service (IaaS) provides virtual machines where the user manages the operating system and software, while the cloud provider handles the underlying hardware. This allows full control over the software stack. PaaS would typically abstract away the OS and restrict customization, while SaaS delivers a fully managed application. FaaS (serverless) offers even less control over the runtime environment.

A company hosts a legacy application on a virtual machine. The application's license is tied to the MAC address of the virtual machine's network interface. The administrator needs to migrate the VM to a different host server without breaking the license. Which of the following virtualization features should the administrator use?

Explanation: Most hypervisors allow setting a static or custom MAC address for a virtual NIC, rather than using the automatically generated one. By configuring the VM's network adapter to use the same MAC address after migration, the licensing software will see the same identifier and continue to work. Features like VLAN tagging, jumbo frames, and network bonding do not affect the MAC address seen by the application.

A company hosts a production database on a public cloud IaaS platform. The database requires consistent low-latency access to a storage volume that can be attached to a single virtual machine. The volume must persist independently of the VM's lifecycle, meaning data should remain intact even if the VM is stopped and started. The workload requires up to 10,000 IOPS. Which of the following cloud storage types should the technician configure to meet these requirements?

Explanation: Block storage (such as Amazon EBS) provides persistent, high-performance storage volumes that can be attached to a single VM. It offers configurable IOPS levels and data persists after the VM is stopped. Object storage (A) is designed for unstructured data and accessed via API, not as a block device. Instance store (B) is ephemeral storage tied to the VM's lifecycle; data is lost when the VM is stopped or terminated. Network File System (D) is a file-level protocol that typically has higher latency and is shared among multiple VMs, not ideal for low-latency database storage requiring high IOPS.

A company hosts a critical application on a public cloud provider. The solution is designed with a set of pre-configured virtual machines that are kept powered off in a different availability zone. In the event of a failure in the primary zone, the standby VMs are automatically started, and traffic is rerouted. This design primarily addresses which of the following cloud computing characteristics?

Explanation: Disaster recovery (DR) involves replicating data and systems to a secondary site and activating them after a disaster. In this scenario, the standby VMs are powered off and started only when needed, which is typical of a cold standby DR solution. High availability (HA) implies immediate failover with no downtime, often using active-active or hot standby configurations. Fault tolerance means the system continues to operate without interruption despite component failures. Scalability is about adjusting resources to handle varying load. Therefore, the correct answer is disaster recovery.
