About the Exam 70-345: Designing and Deploying Microsoft Exchange Server 2016 Exam

Exchange design decisions connect recipient needs with mailbox configuration, transport behavior, and access paths. Relevant concepts include user, shared, and resource mailboxes; receive connector IP restrictions; message-size limits; and controls that distinguish internal delivery from external sending. Client-access work involves setting Outlook on the web virtual-directory host names and placing a reverse proxy between internet users and internal Exchange servers. Administration also requires understanding role-based access control for separating server administration from recipient support. Troubleshooting scenarios may require checking whether a mailbox database is mounted or inspecting directory recipient objects when address resolution fails. These skills support planning and operating messaging services while balancing availability, access, and policy requirements.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A company needs an Exchange mailbox to send and receive messages for a service account, but the mailbox should not be associated with a person's interactive sign-in. Which mailbox type best fits?

  1. AEquipment mailbox
  2. BRoom mailbox
  3. CShared mailbox
  4. DDiscovery mailbox
Show answerCorrect answer: C

A shared mailbox is intended for access by multiple users and commonly does not require its own direct sign-in for routine use. Room and equipment mailboxes represent reservable resources; discovery mailboxes support eDiscovery search results.

Question 2

A company needs to control which servers can submit messages through a receive connector by matching the connecting systems' IP addresses. Which connector property is central to this design?

  1. ARemote IP address ranges
  2. BMailbox database name
  3. CAccepted domain type
  4. DRetention policy tag
Show answerCorrect answer: A

Receive connectors use remote IP address ranges to identify which source systems may connect through that connector, alongside other connector settings such as permission groups and authentication. The other options are unrelated to receive-connector source restrictions.

Question 3

A company needs to publish Outlook on the web and Exchange ActiveSync through a reverse proxy while keeping the internal Exchange servers off the public Internet. Which design is most appropriate?

  1. AExpose the Mailbox servers directly and rely only on client-side antivirus
  2. BPlace a supported reverse proxy or load-balancing layer in front of the Exchange client-access namespace
  3. CPublish the Active Directory domain controllers as the external endpoint
  4. DRoute all client traffic through the Edge Transport server as an HTTP proxy
Show answerCorrect answer: B

A reverse proxy or suitable load-balancing layer can publish Exchange client-access services while separating the public endpoint from the internal Mailbox servers. Edge Transport is designed for mail-flow functions, not as an HTTP reverse proxy.

Question 4

An organization wants to prevent a user from sending messages larger than a defined limit while leaving the organization-wide transport limits unchanged. Where should the limit be set?

  1. AOn the user's mailbox message-size settings
  2. BIn the accepted domain configuration
  3. CIn the database copy configuration
  4. DOn the organization's address book policy
Show answerCorrect answer: A

Mailbox-level send and receive size limits can apply a narrower limit to an individual mailbox without changing broader organization or transport settings. Accepted domains, database copies, and address book policies do not set an individual sender's message-size limit.

Question 5

An organization wants to allow Exchange administrators to manage servers while keeping routine recipient-management tasks delegated to a separate support team. Which Exchange capability is designed for this separation of duties?

  1. ARole Based Access Control (RBAC)
  2. BDatabase availability groups
  3. CAddress book policies
  4. DTransport high availability
Show answerCorrect answer: A

RBAC assigns administrative permissions through management roles and role groups, allowing organizations to delegate specific tasks without granting full administrative access. The other choices address availability or recipient views rather than administrative delegation.

Question 6

A user reports that messages addressed to a particular recipient are rejected because Exchange cannot resolve the recipient to a mailbox or contact. Which directory object should be checked first?

  1. AThe recipient's mail-enabled user or mailbox object and its proxy addresses
  2. BThe server's database availability group membership
  3. CThe organization's federation trust
  4. DThe mailbox database's circular logging setting
Show answerCorrect answer: A

Exchange resolves recipients using directory recipient objects and their email addresses, including proxy addresses. Checking the recipient object and address configuration is a direct first step for an address-resolution problem.

Question 7

An administrator is troubleshooting a mailbox database that will not mount after a service restart. Which Exchange component should be checked first to confirm the database's current mounted state and related status?

  1. AThe mailbox database status in Exchange management tools
  2. BThe organization's email address policy
  3. CThe global address list membership
  4. DThe Outlook profile's cached mode setting
Show answerCorrect answer: A

Exchange management tools expose mailbox database state, including whether a database is mounted, which is a direct first check in this scenario. Address policies, address lists, and client cache settings do not establish database mount state.

How to use this practice test

The free practice bank contains 50 questions, with up to 20 random questions in a session. Complete a session to see your results, then use missed items to identify which Exchange configuration or troubleshooting decisions need further review.

Preparation tips

  • Compare user, shared, and room mailbox purposes, including how resource mailboxes support calendar-based reservations.
  • Trace how receive connector remote IP ranges restrict connecting systems, and distinguish that control from message-size limits.
  • Map Outlook on the web and Exchange ActiveSync publishing through a reverse proxy without exposing internal Exchange servers directly.
  • Review how role-based access control separates server administration from recipient-management tasks.
  • Practice diagnosing recipient-resolution failures and database mount status using the relevant Exchange directory and database information.
