A customer portal runs from a primary data center. Management wants the secondary site to take over within minutes if the primary site loses power, and the secondary site should already have current systems and data ready to serve users. Which design best fits this requirement?

A customer portal runs from a primary data center. Management wants the secondary site to take over within minutes if the primary site loses power, and the secondary site should already have current systems and data ready to serve users. Which design best fits this requirement?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

A single backup server with larger disks and more memory

Extra capacity on one server does not create site-level resilience. If the facility loses power, the larger server fails with everything else.

B

Distractor review

A cold site with nightly backups stored offsite

A cold site is inexpensive, but it requires substantial setup time before it can serve production traffic. That would not meet a failover-in-minutes requirement.

C

Best answer

A hot site with synchronized data replication and automated failover

A hot site is already prepared to operate and can receive traffic quickly when the primary site fails. Synchronized replication keeps data current, and automated failover minimizes manual intervention and recovery time. This is the best match for a near-immediate continuity requirement.

D

Distractor review

RAID 0 across two storage arrays in the primary data center

RAID 0 improves performance but provides no fault tolerance. It also does not protect against a total site outage.

Common exam trap

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Technical deep dive

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ

Questions learners often ask

What does this SY0-701 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: A hot site with synchronized data replication and automated failover — A hot site is the best option when the organization needs rapid site-level failover with current data and systems already prepared. Synchronized replication helps ensure the secondary site is usable with minimal data loss, and automated failover reduces the time and manual steps required to restore service. This is much closer to the stated requirement than a cold site or a single-server solution. Why others are wrong: Option A can be economical, but it takes too long to rebuild after a disaster. Option C addresses storage redundancy only and does nothing for a data-center outage. Option D is still a single point of failure because it does not provide an alternate operational site.
