Cisco 200-301 Practice Test 41

Question 400

A Cisco PAT rule is `ip nat inside source list 10 interface Gi0/1 overload`. The ACL permits 10.25.30.0/24, but one host 10.25.31.17 remains untranslated even with correct inside/outside markings. What policy detail explains the symptom?

  1. An IPv4 address must be changed to match the public interface before NAT can operate.
  2. The overload keyword disables address translation for all TCP sessions.
  3. The NAT source ACL does not match 10.25.31.17, so that host is outside the eligible translation set.
  4. A router can perform NAT only if OSPF is disabled on the inside interface.

Explanation

Correct Answer

C:

An ACL named in an IOS inside-source NAT overload statement selects which inside-local sources may be translated. Host 10.25.31.17 is outside the permitted 10.25.30.0/24 network, so the rule will not create the expected translation for it. Update the approved source match only if this subnet is authorized to use PAT.

Incorrect Answers

A:

NAT is designed to translate internal sources to a global address, not require the host to use the outside IP. Its source selection is determined by the ACL.

B:

Overload permits many inside sessions to share the outside address using translated identifiers. The observed exclusion is the mismatched source ACL.

D:

Routing protocols do not inherently prevent PAT. The relevant evidence is the NAT statement’s source ACL and interface roles.

Question 401

A branch reports that NAT is enabled but operators need to know how many translations are active, whether a pool is exhausted and which interfaces are marked inside/outside. Which IOS verification view is useful?

  1. Use only `show spanning-tree` to count public NAT allocations.
  2. Increase the device hostname length until translations become visible.
  3. Use `show vlan brief` as the sole proof that a session has been translated.
  4. Inspect `show ip nat statistics` alongside the current NAT translation table.

Explanation

Correct Answer

D:

The statistics view summarizes NAT activity, configured pool or overload use and related counters on supported IOS platforms. The translation table provides concrete inside-local and inside-global entries for active flows. These operational checks distinguish a source-match issue from pool capacity or interface-marking problems without changing configuration.

Incorrect Answers

A:

STP displays Layer 2 loop prevention state and does not report IP NAT pool capacity or active translation entries. It is a different subsystem.

B:

Hostname formatting has no influence on NAT hit counters or pool allocations. Read the operational NAT commands instead of making unrelated changes.

C:

VLAN membership cannot display actual IP source and port mappings. A client can be in the correct VLAN and still fail NAT selection.

Question 402

A network team changes a PAT rule from outside interface Gi0/1 to Gi0/2 but existing session mappings still reference the former outside global address until they expire. What is the appropriate operational consideration?

  1. Existing stateful NAT translations may need controlled expiry or selective clearing before all new sessions reflect the revised outside mapping.
  2. A new NAT rule immediately changes all previously transmitted packets at remote hosts.
  3. Changing the outside port also automatically changes every client’s assigned IPv4 address.
  4. Switching PAT interfaces requires disabling Layer 2 spanning tree across all VLANs.

Explanation

Correct Answer

A:

NAT translations maintain state for active conversations and can outlive a change to the configured overload interface. An engineer should inspect the current translation table, consider active session impact, and allow expiration or clear only the necessary entries under approved maintenance. Editing the CLI rule alone does not rewrite the history of every open session instantaneously.

Incorrect Answers

B:

Previously sent packets cannot be rewritten retroactively. Existing translations may persist until removed or expired, so client sessions may need to reconnect.

C:

PAT modifies session mappings at the border router, not DHCP leases on every inside host. Client addressing remains a separate service.

D:

STP protects switch topology and has no role in the lifetime of NAT session entries. Disabling it adds risk without fixing stale mappings.

Question 403

An access switch’s event logs are ten minutes behind the rest of the infrastructure. A trusted time source exists at 192.0.2.50. Which client-side IOS configuration directly synchronizes its clock?

  1. Configure `ntp server 192.0.2.50` and verify synchronization status.
  2. Configure `ip name-server 192.0.2.50` instead.
  3. Change the SSH session timeout to ten minutes.
  4. Enable CDP advertisements toward the NTP server.

Explanation

Correct Answer

A:

An NTP client exchanges timing messages with an identified server and adjusts its clock according to the protocol’s time-selection mechanisms. The `ntp server` command makes the switch a client of the approved source, improving consistency of log timestamps. Network reachability and security or authentication constraints still need validation.

Incorrect Answers

B:

The name-server command configures DNS resolution, not time synchronization. It will not align the switch clock with the time source.

C:

An SSH idle timer limits management sessions, not clock drift. It cannot correct log timestamp differences.

D:

CDP is local device discovery and does not synchronize clocks over NTP. The time source is reached using IP/NTP services.

Question 404

A network has several possible NTP sources with different stratum levels. The local device currently uses one valid source. What does stratum primarily describe?

  1. The relative number of timing levels between a system and a reference clock.
  2. The TCP window size used for log transfers.
  3. The number of Ethernet VLANs traversed by timing packets.
  4. The router’s OSPF cost toward the server.

Explanation

Correct Answer

A:

NTP stratum is a measure of a time source’s position in the reference hierarchy, with lower nonzero values generally closer to a reference clock. It is not a generic signal quality grade or Ethernet speed metric. Clock choice also involves reachability, correctness and selection rules, not stratum alone.

Incorrect Answers

B:

NTP ordinarily uses UDP timing messages rather than a TCP flow-control window. A transport window has no direct relationship to clock stratum.

C:

VLAN count is a network topology measure and is not the NTP reference hierarchy. Stratum relates to timing ancestry.

D:

Routing metrics influence network path choice but do not define the NTP timing hierarchy. A network path can be short while its clock source is unsynchronized.

Question 405

An engineer has configured `ntp server 198.51.100.10` on a router. The router can ping the server but its NTP peer state is not synchronized. What should be verified next?

  1. Declare synchronization complete because ping succeeded.
  2. Change the switch native VLAN to the NTP server IP.
  3. Configure an OSPF stub area for the router’s management interface.
  4. Check NTP association status, server synchronization and whether required UDP NTP traffic is permitted.

Explanation

Correct Answer

D:

ICMP reachability alone does not establish a valid NTP relationship. The server may not be synchronized, NTP packets may be blocked or authentication may be incompatible. Inspect NTP association and status outputs, peer health and transport policy rather than assuming ping proves time selection.

Incorrect Answers

A:

Ping proves limited IP reachability, not successful NTP message exchange or selection of a valid time source. The clock can still be unsynchronized.

B:

A native VLAN is a numeric Layer 2 tagging configuration, not an IP NTP association target. It cannot repair UDP timing exchange.

C:

OSPF area design does not guarantee NTP peer synchronization. Check the application’s timing protocol and packet reachability first.

Question 406

A Cisco switch is an NTP client and needs timestamps to remain consistent with its monitoring server for incident correlation. Why is merely setting `clock set` once insufficient for long-term operation?

  1. Changing the VLAN ID once causes automatic clock correction.
  2. ARP cache aging performs time synchronization with adjacent hosts.
  3. A manual clock always stays synchronized to UTC without a reference.
  4. A manually set clock can drift; continuous NTP synchronization tracks an approved reference.

Explanation

Correct Answer

D:

Local oscillator clocks drift due to hardware and environmental effects. Periodic NTP exchanges estimate offset and help maintain consistent time across devices, improving log correlation. A one-time manual setting may look correct initially but lacks a continuous mechanism for adjusting later deviations.

Incorrect Answers

A:

VLAN numbers are segmentation identifiers; they do not set or maintain time. Clock synchronization uses a time protocol.

B:

ARP removes stale IPv4 neighbor mappings but does not exchange reference-clock offsets. Its timer role is unrelated to NTP.

C:

No ordinary device clock is guaranteed never to drift after one adjustment. A maintained time reference is required for consistent multi-device logging.

Question 407

A Cisco router is intended to provide time to many access switches after it has synchronized to a trusted upstream source. Which server-side role must be verified?

  1. The router advertises an SSID containing the current time.
  2. The router uses a lower OSPF administrative distance than its peers.
  3. The router is reachable and responding as a supported NTP server to authorized downstream clients.
  4. The router disables inbound UDP traffic from every managed switch.

Explanation

Correct Answer

C:

A device that supplies time to others must have a valid reference time and permit client NTP exchanges on the intended interfaces. Downstream switches then configure it as their time source. Simply setting a calendar display manually may not provide traceable synchronized time to the rest of the network.

Incorrect Answers

A:

An SSID is a wireless network name and cannot convey NTP time service to wired switches. A time protocol endpoint is required.

B:

Route source preference does not mean the device is synchronized or serving NTP requests. IP reachability is only one prerequisite.

D:

Blocking all NTP client exchanges would prevent downstream synchronization. Access controls should permit authorized requests while restricting untrusted sources.

Question 408

A client already has working IP connectivity to a web server’s address 203.0.113.50 but cannot resolve `app.example` to that address. Which infrastructure service should be investigated?

  1. DNS name resolution and its records or configured resolver.
  2. NAT overload port preservation only.
  3. Ethernet duplex negotiation as the sole explanation.
  4. OSPF DR election between the client and server.

Explanation

Correct Answer

A:

DNS converts domain names into resource records such as A and AAAA addresses. Reaching the destination by numeric IP while a hostname lookup fails points toward resolver settings, authoritative records or DNS transport. DHCP may have supplied a DNS server option, but it does not itself answer the application name query.

Incorrect Answers

B:

PAT controls address and transport-port translation, not the content of DNS zone records. An IP-reachable server with failing hostname resolution needs resolver investigation.

C:

A physical duplex failure would usually impair numeric-IP connectivity too. The stated selective hostname failure implicates the name-resolution process.

D:

A normal web client does not form OSPF neighbors with the remote server, and the IP path already works. The missing mapping is DNS.

Question 409

A service administrator wants a hostname to resolve to a different name managed by the same operations team rather than to a literal IP address. What DNS record supports the alias?

  1. An MX record selecting the service’s default gateway.
  2. A CNAME resource record pointing the alias toward the canonical hostname.
  3. A PTR record linking the alias to an IPv4 mask.
  4. A DHCP pool option that renames every destination hostname.

Explanation

Correct Answer

B:

CNAME records alias one DNS name to another canonical name, allowing clients to follow the target record set to find the service address. This separates presentation names from A/AAAA endpoint records under normal DNS constraints. It is not a way to create network routing or allocate DHCP leases.

Incorrect Answers

A:

MX records indicate mail exchangers, not a general name alias or IP next hop. The request concerns one hostname resolving via another.

C:

PTR records serve reverse address-to-name lookup rather than ordinary forward aliasing. They cannot substitute for CNAME alias semantics.

D:

DHCP assigns client network configuration, not authoritative aliases for arbitrary service names. DNS holds the alias relationship.

Question 410

A DHCP server has sufficient free addresses but clients in a separate VLAN cannot reach it because DHCP discovery is initially broadcast within their local subnet. What network feature is needed on the routing boundary?

  1. A static DNS A record for every client.
  2. An authorized DHCP relay agent configured to forward requests to the server.
  3. A CDP neighbor command between the clients and router.
  4. A larger client subnet mask without changing the router.

Explanation

Correct Answer

B:

DHCP clients typically begin IPv4 address discovery with local broadcasts that routers do not forward as ordinary broadcasts. A relay receives the client request and forwards it toward the DHCP server using routable IP communication, preserving relevant relay information. Its configuration belongs on the client VLAN gateway or supported relay interface.

Incorrect Answers

A:

DNS maps names to addresses but does not transport the DHCP broadcast to another subnet. The clients need a lease transaction.

C:

CDP is local device discovery, not the mechanism for forwarding DHCP messages to a remote server. The relay feature is required.

D:

Altering the client subnet definition can create addressing conflicts and does not implement cross-subnet DHCP relay. The existing routing boundary still separates broadcasts.
