Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 199

A developer must deploy a containerized application for network device inventory management. The developer sets up a Kubernetes cluster on two separate hypervisors. The SLA is not currently meeting a specified maximum value for network latency/jitter. CPU/memory and disk I/O are functioning properly. Which two design approaches resolve the issue? (Choose two.)

Answer options

• A. Enable IPv6 within the cluster.
• B. Upgrade the server NIC card.
• C. Deploy the cluster to a bare metal server.
• D. Replace the HDD drives with SSD drives.
• E. Collocate services in the same pod.

Correct answer: B, E

Explanation

Upgrading the server NIC card can improve network performance, thus addressing latency and jitter issues. Collocating services in the same pod reduces inter-pod communication overhead, further enhancing network efficiency. The other options do not directly address the specific network latency/jitter concerns.
