Question 590
A two-tier web app fails disaster recovery tests because the web frontend starts before its database service is reachable. Which TWO complementary steps provide the appropriate administrative response and its supporting assessment? Select TWO.
Explanation
Correct Answers
Build an Azure Site Recovery recovery plan that sequences identity, database and application recovery groups with scripts or runbooks where appropriate, and rehearse failover and failback. This response targets the system boundary described in the case. Successful replication of each VM is not sufficient for multi-tier disaster recovery; orchestrated dependency order and test execution are essential. Before applying it, verify: Review service dependencies, recovery plan groups, available recovery points, test failover network, re-protection state, and automation credentials. This is the response half of the pair. Situation: A two-tier web app fails disaster recovery tests because the web frontend starts before its database service is reachable.
Review service dependencies, recovery plan groups, available recovery points, test failover network, re-protection state, and automation credentials. This evidence tests the likely failure point before changing production configuration. Successful replication of each VM is not sufficient for multi-tier disaster recovery; orchestrated dependency order and test execution are essential. The corresponding response is: Build an Azure Site Recovery recovery plan that sequences identity, database and application recovery groups with scripts or runbooks where appropriate, and rehearse failover and failback. This is the verification prerequisite half of the pair. Situation: A two-tier web app fails disaster recovery tests because the web frontend starts before its database service is reachable.
Incorrect Answers
Enable supported Azure Site Recovery replication for eligible VMs and configure target location, replication policies, storage, networking and test failover isolation according to RPO/RTO needs. This step is relevant to Azure Site Recovery policy and network mapping but is not one of the complementary steps this case needs. The intended pair is: Build an Azure Site Recovery recovery plan that sequences identity, database and application recovery groups with scripts or runbooks where appropriate, and rehearse failover and failback. and Review service dependencies, recovery plan groups, available recovery points, test failover network, re-protection state, and automation credentials. Situation: A two-tier web app fails disaster recovery tests because the web frontend starts before its database service is reachable.
Inspect Replica server trust, authentication mode, listener port, VM replication configuration, log size, compression settings, and missed replication cycles. This step is relevant to Hyper-V Replica authentication and replication health but is not one of the complementary steps this case needs. The intended pair is: Build an Azure Site Recovery recovery plan that sequences identity, database and application recovery groups with scripts or runbooks where appropriate, and rehearse failover and failback. and Review service dependencies, recovery plan groups, available recovery points, test failover network, re-protection state, and automation credentials. Situation: A two-tier web app fails disaster recovery tests because the web frontend starts before its database service is reachable.
Eligible domain members establish authenticated traffic where required while untrusted machines cannot silently join the isolated zone. This step is relevant to Windows IPsec connection security and domain isolation but is not one of the complementary steps this case needs. The intended pair is: Build an Azure Site Recovery recovery plan that sequences identity, database and application recovery groups with scripts or runbooks where appropriate, and rehearse failover and failback. and Review service dependencies, recovery plan groups, available recovery points, test failover network, re-protection state, and automation credentials. Situation: A two-tier web app fails disaster recovery tests because the web frontend starts before its database service is reachable.
