A company implements a web farm with 100 servers behind an application load balancer. Dunng scaling events, new web servers that are placed in service have not loaded all their modules, which causes some requests to the web farm to fail.
Which of the following should the cloud engineer implement to address the scaling issue?

  1. Instance warm-up
  2. Scheduled scaling
  3. Event-based scaling
  4. Load balancer passthrough

Answer(s): A

Explanation:

Implementing an instance warm-up period can address the issue of new web servers not having all modules loaded during scaling events. This warm-up period allows new instances to fully initialize and start serving traffic only when they are ready, preventing failed requests.


Reference:

Scaling strategies and their operational impact, including the concept of instance warm- up, are covered under cloud infrastructure management in the CompTIA Cloud+ curriculum.



Which of the following is the most cost-effective way to store data that is infrequently accessed?

  1. Cold site
  2. Hot site
  3. Off-site
  4. Warm site

Answer(s): C

Explanation:

The most cost-effective way to store data that is infrequently accessed is typically an off-site storage service, often referred to as cold or archival storage. This type of storage is designed for data that is rarely accessed, providing lower storage costs.


Reference:

Data storage solutions and their cost implications, including off-site (cold or archival) storage for infrequently accessed data, are part of the cloud storage options discussed in CompTIA Cloud+.



Which of the following provides secure, private communication between cloud environments without provisioning additional hardware or appliances?

  1. VPN
  2. VPC peering
  3. BGP
  4. Transit gateway

Answer(s): B

Explanation:

VPC peering provides secure, private communication between cloud environments without the need for provisioning additional hardware or appliances. It allows direct network connectivity between two Virtual Private Clouds (VPCs), enabling resources in either VPC to communicate with each other using private IP addresses.


Reference:

Cloud networking options such as VPC peering and its benefits are included in the networking concepts of cloud environments in the CompTIA Cloud+ certification.



Which of the following network protocols is generally used in a NAS environment?

  1. BGP
  2. RDP
  3. TCP/IP
  4. iSCSI

Answer(s): C

Explanation:

The network protocol generally used in a NAS (Network Attached Storage) environment is TCP/IP (Transmission Control Protocol/Internet Protocol). NAS devices are accessed over a network rather than being directly connected to the computer, and they utilize the TCP/IP protocol to enable this network communication.


Reference:

Understanding of networking protocols, including TCP/IP in the context of NAS environments, is part of the foundational networking knowledge for cloud services in CompTIA

Cloud+.
