CompTIA 220-1201 Practice Test 57
Question 560
During Stonebridge Research's cloud and desktop infrastructure review, the technician encounters this condition: A seasonal ticket service needs temporary compute capacity only during sale windows. The desired outcome is to recognize elasticity as capacity adjustment to changing utilization. The customer requires a verified fix rather than a guess based on one symptom. Which configuration or repair action best addresses the stated requirement?
- Describe the combination as hybrid cloud rather than calling it wholly public or wholly private
- Deploy a supported VDI solution with centrally hosted desktop sessions
- Configure supported autoscaling rules with limits for traffic-driven elasticity
- Select dedicated hosting only when explicitly required and otherwise verify tenant isolation controls
Explanation
Correct Answer
C:
Configure supported autoscaling rules with limits for traffic-driven elasticity. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that a seasonal ticket service needs temporary compute capacity only during sale windows. The support goal is to recognize elasticity as capacity adjustment to changing utilization; this design action specifically addresses cloud elasticity versus fixed provisioning without confusing a different subsystem.
Incorrect Answers
A:
Describe the combination as hybrid cloud rather than calling it wholly public or wholly private. That action is appropriate for public versus private versus hybrid cloud, normally when an enterprise must keep one legacy regulatory workload in its own datacenter while scaling an unrelated web front end in a public provider. Here the observed facts require cloud elasticity versus fixed provisioning instead.
B:
Deploy a supported VDI solution with centrally hosted desktop sessions. This action is appropriate for vdi versus local desktop processing, normally when a company wants centrally managed user desktops accessed from inexpensive endpoints. Here the observed facts require cloud elasticity versus fixed provisioning instead.
D:
Select dedicated hosting only when explicitly required and otherwise verify tenant isolation controls. That action is appropriate for multitenancy versus dedicated cloud resources, normally when an organization uses a SaaS platform shared with several customer organizations. Here the observed facts require cloud elasticity versus fixed provisioning instead.
Question 561
A support request at Stonebridge Research presents this problem: A customer receives a fiber-to-the-premises service but attempts to connect the optical fiber directly to a DOCSIS cable modem. The supporting record states that the provider hands off optical PON through an optical network terminal. The desired outcome is to choose access equipment that terminates the actual carrier medium. The goal is to restore required function without creating a new security or safety problem. Which configuration or repair action best addresses the stated requirement?
- Use a switch or injector capacity that satisfies the combined supported PoE draw
- Provide a suitable router or Layer 3 routing function with permitted inter-subnet paths
- Use the provider-approved ONT for fiber access and connect a router to its supported handoff
- Repair the DNS server or client DNS setting rather than rebuilding the DHCP address pool
Explanation
Correct Answer
C:
Use the provider-approved ONT for fiber access and connect a router to its supported handoff. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that the provider hands off optical PON through an optical network terminal. The support goal is to choose access equipment that terminates the actual carrier medium; this design action specifically addresses ont versus cable modem access equipment without confusing a different subsystem.

Here the observed facts require ont versus cable modem access equipment instead.
B:
Provide a suitable router or Layer 3 routing function with permitted inter-subnet paths. This action is appropriate for router versus layer 2 switch forwarding, normally when two PCs on separate IPv4 subnets can communicate within their own LANs but not across subnets. Here the observed facts require ont versus cable modem access equipment instead.
D:
Repair the DNS server or client DNS setting rather than rebuilding the DHCP address pool. This action is appropriate for dns resolution versus dhcp address assignment, normally when a workstation has a valid IPv4 address, gateway and lease but cannot reach services by hostname. Here the observed facts require ont versus cable modem access equipment instead.
Question 562
A support request at Granite Capital presents this problem: A high-end PC unexpectedly restarts only when a new graphics card is heavily used. The desired outcome is to differentiate load-related power failure from random OS application crashes. Service work must follow power isolation, ESD, and manufacturer instructions when applicable. Which inspection most directly confirms the likely cause before changing components?
- Inspect UEFI boot entries, disk detection and approved operating system bootloader
- Check documented beep codes, DIMM seating, and one-module test configuration
- Correlate reboot timing with power demand and inspect PSU rating and connector seating
- Check the exact board beep code table, GPU seating and required GPU power
Explanation
Correct Answer
C:
Correlate reboot timing with power demand and inspect PSU rating and connector seating. It checks the likely failure boundary before altering working parts or settings. The relevant observation is that a high-end PC unexpectedly restarts only when a new graphics card is heavily used. The support goal is to differentiate load-related power failure from random OS application crashes; this diagnose action specifically addresses psu instability under peak component load without confusing a different subsystem.

Here the observed facts require intermittent monitor image due to video cable instead.
B:
Inspect channel use, signal strength, client retries and non-Wi-Fi interference sources. This action is appropriate for intermittent wi-fi due to channel interference, normally when users near a lunchroom suffer slow 2.4 GHz Wi-Fi at peak periods while wired links stay normal. Here the observed facts require intermittent monitor image due to video cable instead.
D:
Confirm selected input, cable path, external display detection and output mode. This action is appropriate for projector wrong input versus computer failure, normally when a conference room projector displays a no-signal message while the laptop works locally.

Question 568
At Amberline Finance, a technician working in cloud and desktop infrastructure review identifies this issue: An engineer keeps only hypervisor checkpoints on the same datastore and assumes disk failure cannot lose them. The desired outcome is to differentiate state rollback checkpoints from separately stored recoverable backups. User data and business service continuity must be preserved. What should the technician recommend as the corrective approach?
- Select a supported Type 1 bare-metal hypervisor for the production host requirement
