SwiftCache Overview and Deployment

Part 1 - Cache Overview and Deployment

Which product would be used to save bandwidth for generic HTTP traffic?

  • SwiftCache
  • SwiftServe
  • SwiftCDN
  • SwiftCoder

What is required to cache HTTPS traffic?

  • Nothing, SwiftCache can do it out of the box
  • A special flag set on the SwiftCache
  • A letter of permission from the content provider
  • A Certificate Authority installed on every client device

How does caching benefit the end user?

  • Faster delivery
  • Access to more content
  • Lower bandwidth usage over the user ---> Cache link
  • Less media loaded

What happens when the cache hits it’s soft throughput limit?

  • The cache sends an email to the support system
  • The cache stops caching any bandwidth over the limit, bypassing some new connections
  • The cache stops caching anything, bypassing all new connections
  • The cache starts dropping connections until the throughput decreases again
  • The cache starts dropping connections until reset manually

What happens when the cache hits it’s hard throughput limit?

  • The cache sends an email to the support system
  • The cache stops caching any bandwidth over the limit, bypassing some new connections
  • The cache stops caching anything, bypassing all new connections
  • The cache starts dropping connections until the throughput decreases again
  • The cache starts dropping connections until reset manually

When would you recommend a smaller SC 1100? (Multiple Choice)

  • Schools
  • Small Universities
  • Large Campuses
  • Enterprises
  • ISPs

What factor affects the throughput performance of a cache?

  • Power supply
  • Connection to SwiftSense
  • Traffic profiles
  • Country of origin

What is the potential danger of Explicit mode? (Multiple Choice)

  • Will let explicit content through
  • Might create an open proxy
  • Will not perform as well
  • Both parties will see the IP of the cache

In which mode do both the server and the user NOT see the cache’s IP?

  • Fully-transparent mode
  • Semi-transparent mode
  • Explicit mode
  • Hidden mode

Why is an out-of-path deployment better than an inline deployment?

  • Better performance
  • Cache failure doesn’t always mean a service outage
  • It sounds more impressive
  • It requires less configuration

What isn’t a reason to use a load balancer?

  • Allows higher performance than a single cache
  • Allows a cache to fail without affecting delivery
  • It is more cost efficient in CAPEX
  • Allows a cache to be serviced without affecting delivery

What advantage does routing requests to load-balanced caches based on URL or domain give (i.e. URL hash based routing)?

  • Caches can learn policies better for fewer sites
  • Fewer sites handled per cache means better use of storage
  • Better reliability if a cache fails
  • Makes the caches harder to hack
