Question 1

Mesa needs an IPv4 default route through next hop 192.0.2.1. Which command is correct? Choose ONE.

  1. ip default-gateway 192.0.2.1
  2. ip route 0.0.0.0 0.0.0.0 192.0.2.1
  3. ipv6 route ::/0 192.0.2.1
  4. ip route 255.255.255.255 0.0.0.0 192.0.2.1

Correct Answer: B

Correct Answer

 

 

Answer B is correct because An IPv4 default static route uses destination 0.0.0.0 with mask 0.0.0.0 and the desired next hop. For CHG-7824 at Mesa, the branch administrator checks Mesa’s protocol state; CHG-7824 is judged from the observable result at Mesa. For CHG-7824, this choice fits Mesa: the branch administrator gets the required Mesa outcome and can verify CHG-7824 directly.

Incorrect Answers

 

Answer D is incorrect because 255.255.255.255 is not the IPv4 default-route destination. For CHG-7824 at Mesa, the branch administrator checks Mesa’s protocol state; CHG-7824 is judged from the observable result at Mesa. For CHG-7824, this choice fails Mesa: the branch administrator leaves the required Mesa condition unmet and, under t11-pt1-q01, should reject it for chg-7824.

Answer A is incorrect because `ip default-gateway` is not the routed-device static route used when IP routing is operating. For CHG-7824 at Mesa, the branch administrator checks Mesa’s protocol state; CHG-7824 is judged from the observable result at Mesa. For CHG-7824, this choice fails Mesa: the branch administrator leaves the required Mesa condition unmet and, under t11-pt1-q01, should reject it for chg-7824.

Answer C is incorrect because That is IPv6 route syntax and cannot install an IPv4 default route. For CHG-7824 at Mesa, the branch administrator checks Mesa’s protocol state; CHG-7824 is judged from the observable result at Mesa. For CHG-7824, this choice fails Mesa: the branch administrator leaves the required Mesa condition unmet and, under t11-pt1-q01, should reject it for chg-7824.

 

Question 2

Pioneer needs an IPv6 default static route through 2001:db8:1::1. Which command fits? Choose ONE.

  1. ip route 0.0.0.0 0.0.0.0 2001:db8:1::1
  2. ipv6 route ::/0 2001:db8:1::1
  3. ipv6 default-gateway 2001:db8:1::1
  4. ipv6 route 2001:db8::/128 2001:db8:1::1

Correct Answer: B

Correct Answer

 

 

Answer B is correct because The IPv6 default prefix is ::/0; associating it with the next-hop address creates the requested default static route. For CHG-7841 at Pioneer, the change reviewer checks Pioneer’s protocol state; CHG-7841 is judged from the observable result at Pioneer. For CHG-7841, this choice fits Pioneer: the change reviewer gets the required Pioneer outcome and can verify CHG-7841 directly.

Incorrect Answers

 

Answer A is incorrect because IPv4 `ip route` syntax cannot use an IPv6 next hop. For CHG-7841 at Pioneer, the change reviewer checks Pioneer’s protocol state; CHG-7841 is judged from the observable result at Pioneer. For CHG-7841, this choice fails Pioneer: the change reviewer leaves the required Pioneer condition unmet and, under t11-pt1-q02, should reject it for chg-7841.

Answer D is incorrect because A /128 defines one host destination, not the IPv6 default. For CHG-7841 at Pioneer, the change reviewer checks Pioneer’s protocol state; CHG-7841 is judged from the observable result at Pioneer. For CHG-7841, this choice fails Pioneer: the change reviewer leaves the required Pioneer condition unmet and, under t11-pt1-q02, should reject it for chg-7841.

Answer C is incorrect because Routed IPv6 forwarding uses an IPv6 static route rather than this as a general routed default. For CHG-7841 at Pioneer, the change reviewer checks Pioneer’s protocol state; CHG-7841 is judged from the observable result at Pioneer. For CHG-7841, this choice fails Pioneer: the change reviewer leaves the required Pioneer condition unmet and, under t11-pt1-q02, should reject it for chg-7841.

 

Question 3

Summit must reach network 10.40.0.0/16 through 192.0.2.9. Which IPv4 static route is appropriate? Choose ONE.

  2. ip route 10.40.0.0 255.255.255.0 192.0.2.9
  3. ip route 10.40.0.0 255.255.0.0 192.0.2.9
  4. ip route 192.0.2.9 255.255.255.255 10.40.0.1

Correct Answer: C

Correct Answer

 

 

Answer C is correct because The destination network, correct /16 mask, and reachable next hop create the required network static route. For CHG-7858 at Summit, the branch administrator checks Summit’s protocol state; CHG-7858 is judged from the observable result at Summit. For CHG-7858, this choice fits Summit: the branch administrator gets the required Summit outcome and can verify CHG-7858 directly.

Incorrect Answers

 

Answer B is incorrect because A /24 mask describes only 10.40.0.0/24 and does not cover the full /16 requirement. For CHG-7858 at Summit, the branch administrator checks Summit’s protocol state; CHG-7858 is judged from the observable result at Summit. For CHG-7858, this choice fails Summit: the branch administrator leaves the required Summit condition unmet and, under t11-pt1-q03, should reject it for chg-7858.

Answer D is incorrect because This reverses destination and next-hop roles and creates a host route for the upstream address instead. For CHG-7858 at Summit, the branch administrator checks Summit’s protocol state; CHG-7858 is judged from the observable result at Summit. For CHG-7858, this choice fails Summit: the branch administrator leaves the required Summit condition unmet and, under t11-pt1-q03, should reject it for chg-7858.

Answer A is incorrect because A default route is broader than the specified destination and uses a next hop from the remote network. For CHG-7858 at Summit, the branch administrator checks Summit’s protocol state; CHG-7858 is judged from the observable result at Summit. For CHG-7858, this choice fails Summit: the branch administrator leaves the required Summit condition unmet and, under t11-pt1-q03, should reject it for chg-7858.

 

Question 4

Vector needs a static IPv4 host route only to 203.0.113.77 via 192.0.2.1. Which mask should be used? Choose ONE.

  1. 203.0.113.77 255.255.255.255
  2. 203.0.113.0 255.255.255.0
  3. 203.0.0.0 255.255.0.0
  4. 0.0.0.0 0.0.0.0

Correct Answer: A

Correct Answer

 

 

Answer A is correct because An IPv4 /32 host route uses mask 255.255.255.255, matching only the single specified address. For CHG-7875 at Vector, the change reviewer checks Vector’s protocol state; CHG-7875 is judged from the observable result at Vector. For CHG-7875, this choice fits Vector: the change reviewer gets the required Vector outcome and can verify CHG-7875 directly.

Incorrect Answers

For CHG-7875, this choice fails Vector: the change reviewer leaves the required Vector condition unmet and, under t11-pt1-q04, should reject it for chg-7875.

Answer D is incorrect because The default prefix matches all otherwise-unmatched destinations, not one host. For CHG-7875 at Vector, the change reviewer checks Vector’s protocol state; CHG-7875 is judged from the observable result at Vector. For CHG-7875, this choice fails Vector: the change reviewer leaves the required Vector condition unmet and, under t11-pt1-q04, should reject it for chg-7875.

 

Question 5

Which prefix length creates an IPv6 host static route to 2001:db8:50::25 at Yarrow? Choose ONE.

  1. 2001:db8::/32
  2. 2001:db8:50::25/128
  3. ::/0
  4. 2001:db8:50::/64

Correct Answer: B

Correct Answer

 

 

Answer B is correct because An IPv6 /128 prefix identifies exactly one address and is the IPv6 host-route equivalent of an IPv4 /32. For CHG-7892 at Yarrow, the branch administrator checks Yarrow’s protocol state; CHG-7892 is judged from the observable result at Yarrow. For CHG-7892, this choice fits Yarrow: the branch administrator gets the required Yarrow outcome and can verify CHG-7892 directly.

Incorrect Answers

 

Answer D is incorrect because A /64 describes an entire IPv6 subnet, not one host. For CHG-7892 at Yarrow, the branch administrator checks Yarrow’s protocol state; CHG-7892 is judged from the observable result at Yarrow. For CHG-7892, this choice fails Yarrow: the branch administrator leaves the required Yarrow condition unmet and, under t11-pt1-q05, should reject it for chg-7892.

Answer A is incorrect because A /32 is an aggregate prefix and is far broader than one destination. For CHG-7892 at Yarrow, the branch administrator checks Yarrow’s protocol state; CHG-7892 is judged from the observable result at Yarrow. For CHG-7892, this choice fails Yarrow: the branch administrator leaves the required Yarrow condition unmet and, under t11-pt1-q05, should reject it for chg-7892.

Question 6

Birch has OSPF route 10.60.0.0/16. Which static-route distance would make a backup route float behind OSPF? Choose ONE.

  1. 1
  2. 200
  3. 110
  4. 90

Correct Answer: B

Correct Answer

 

 

Answer B is correct because A static AD of 200 is less preferred than OSPF AD 110, so it becomes eligible only when the preferred OSPF route disappears. For CHG-7909 at Birch, the change reviewer checks Birch’s protocol state; CHG-7909 is judged from the observable result at Birch. For CHG-7909, this choice fits Birch: the change reviewer gets the required Birch outcome and can verify CHG-7909 directly.

Incorrect Answers

 

Answer A is incorrect because The normal static AD 1 would beat OSPF and become primary. For CHG-7909 at Birch, the change reviewer checks Birch’s protocol state; CHG-7909 is judged from the observable result at Birch. For CHG-7909, this choice fails Birch: the change reviewer leaves the required Birch condition unmet and, under t11-pt1-q06, should reject it for chg-7909.

Answer D is incorrect because AD 90 is still lower than 110, so the static route would be preferred. For CHG-7909 at Birch, the change reviewer checks Birch’s protocol state; CHG-7909 is judged from the observable result at Birch. For CHG-7909, this choice fails Birch: the change reviewer leaves the required Birch condition unmet and, under t11-pt1-q06, should reject it for chg-7909.

Answer C is incorrect because An equal distance can create ambiguous competition and does not clearly establish the static route as less preferred backup. For CHG-7909 at Birch, the change reviewer checks Birch’s protocol state; CHG-7909 is judged from the observable result at Birch. For CHG-7909, this choice fails Birch: the change reviewer leaves the required Birch condition unmet and, under t11-pt1-q06, should reject it for chg-7909.

 

Question 7

Elm wants a directly attached static route to 10.70.0.0/16 out GigabitEthernet0/1. Which route element can identify the egress? Choose ONE.

  1. The NTP source interface
  2. The OSPF router ID
  3. The exit interface GigabitEthernet0/1
  4. The DNS server address

Correct Answer: C

Correct Answer

 

 

Answer C is correct because A static route can identify an outgoing interface as the forwarding path, especially on point-to-point links or where that use is operationally appropriate. For CHG-7926 at Elm, the branch administrator checks Elm’s protocol state; CHG-7926 is judged from the observable result at Elm. For CHG-7926, this choice fits Elm: the branch administrator gets the required Elm outcome and can verify CHG-7926 directly.

For CHG-7926 at Elm, the branch administrator checks Elm’s protocol state; CHG-7926 is judged from the observable result at Elm. For CHG-7926, this choice fails Elm: the branch administrator leaves the required Elm condition unmet and, under t11-pt1-q07, should reject it for chg-7926.

Answer A is incorrect because NTP source selection does not create a route to a destination prefix. For CHG-7926 at Elm, the branch administrator checks Elm’s protocol state; CHG-7926 is judged from the observable result at Elm. For CHG-7926, this choice fails Elm: the branch administrator leaves the required Elm condition unmet and, under t11-pt1-q07, should reject it for chg-7926.

 

Question 8

A Highland Ethernet static route should specify both GigabitEthernet0/1 and next hop 192.0.2.2. What type of statement is that? Choose ONE.

  1. A fully specified static route
  2. A floating static route
  3. A dynamic route
  4. A local host route

Correct Answer: A

Correct Answer

 

 

Answer A is correct because A fully specified static route names both the egress interface and next-hop address, making both forwarding elements explicit in the route configuration. For CHG-7943 at Highland, the change reviewer checks Highland’s protocol state; CHG-7943 is judged from, under t11-pt1-q08, the observable result at highland. For CHG-7943, this choice fits Highland: the change reviewer gets the required Highland outcome and can verify CHG-7943 directly.

Answer B is incorrect because Floating describes an intentionally higher administrative distance, not the presence of both interface and next hop. For CHG-7943 at Highland, the change reviewer checks Highland’s protocol state; CHG-7943 is judged from the observable result at Highland. For CHG-7943, this choice fails Highland: the change reviewer leaves the required Highland condition unmet and, under t11-pt1-q08, should reject it for chg-7943.

Answer C is incorrect because Dynamic routes are learned by routing protocols rather than entered with a static destination/interface/next-hop statement. For CHG-7943 at Highland, the change reviewer checks Highland’s protocol state; CHG-7943 is judged from the observable result at Highland. For CHG-7943, this choice fails Highland: the change reviewer leaves the required Highland condition unmet and, under t11-pt1-q08, should reject it for chg-7943.

Answer D is incorrect because Local routes are created automatically for interface addresses and are not defined by this static syntax. For CHG-7943 at Highland, the change reviewer checks Highland’s protocol state; CHG-7943 is judged from the observable result at Highland. For CHG-7943, this choice fails Highland: the change reviewer leaves the required Highland condition unmet and, under t11-pt1-q08, should reject it for chg-7943.

 

Question 9

A Kodiak recursive static route points to 192.0.2.9, but the router loses every route that can reach 192.0.2.9. What happens to the static path? Choose ONE.

  1. Its OSPF cost became too high
  2. The next hop can no longer be resolved to an egress path
  3. The NTP clock changed
  4. Its DNS record expired

Correct Answer: B

Correct Answer

 

 

Answer B is correct because A recursive static route depends on reachability to its next-hop address; losing that resolution prevents the route from being usable for forwarding. For CHG-7960 at Kodiak, the branch administrator checks Kodiak’s protocol state; CHG-7960 is judged from, under t11-pt1-q09, the observable result at kodiak. For CHG-7960, this choice fits Kodiak: the branch administrator gets the required Kodiak outcome and can verify CHG-7960 directly.

For CHG-7960 at Kodiak, the branch administrator checks Kodiak’s protocol state; CHG-7960 is judged from the observable result at Kodiak. For CHG-7960, this choice fails Kodiak: the branch administrator leaves the required Kodiak condition unmet and, under t11-pt1-q09, should reject it for chg-7960.

 

Question 10

Nimbus intends to route 172.20.0.0/16 but configures mask 255.255.255.0. What is the main effect? Choose ONE.

  1. The route becomes a default route
  2. The route covers only 172.20.0.0/24 instead of the required /16
  3. The route becomes a host route
  4. The route automatically summarizes to /16

Correct Answer: B

Correct Answer

 

 

Answer B is correct because Mask 255.255.255.0 creates a /24, so destinations outside the first /24 do not match the intended 172.20.0.0/16 route. For CHG-7977 at Nimbus, the change reviewer checks Nimbus’s protocol state; CHG-7977 is judged from, under t11-pt1-q10, the observable result at nimbus. For CHG-7977, this choice fits Nimbus: the change reviewer gets the required Nimbus outcome and can verify CHG-7977 directly.

Question 15

Orchid uses IPv6 link-local FE80::2 as a static next hop on an Ethernet link. What additional information is normally necessary? Choose ONE.

  1. The NTP source
  2. The DNS domain name
  3. The outgoing interface
  4. The OSPF process ID

Correct Answer: C

For CHG-8113 at Xenon, the change reviewer checks Xenon’s protocol state; CHG-8113 is judged from the observable result at Xenon. For CHG-8113, this choice fails Xenon: the change reviewer leaves the required Xenon condition unmet and, under t11-pt1-q18, should reject it for chg-8113.

 

Question 19

Aspen configures two static routes to the same prefix with identical administrative distance and valid independent next hops. What can the router do? Choose ONE.

  1. Choose the path with the numerically smaller next-hop IP
  2. Always reject the second static route
  3. Install multiple equal-cost static paths if supported
  4. Convert both routes to OSPF

Correct Answer: C

Correct Answer

 

 

Answer C is correct because Equal-cost static routes to the same destination can coexist and provide load sharing when both next hops are valid and the platform permits multiple paths. For CHG-8130 at Aspen, the branch administrator checks Aspen’s protocol state; CHG-8130 is judged from, under t11-pt1-q19, the observable result at aspen. For CHG-8130, this choice fits Aspen: the branch administrator gets the required Aspen outcome and can verify CHG-8130 directly.

Incorrect Answers

 

Answer B is incorrect because A second equal-cost static path is not inherently rejected simply because the first exists. For CHG-8130 at Aspen, the branch administrator checks Aspen’s protocol state; CHG-8130 is judged from the observable result at Aspen. For CHG-8130, this choice fails Aspen: the branch administrator leaves the required Aspen condition unmet and, under t11-pt1-q19, should reject it for chg-8130.

Answer D is incorrect because Static routes do not become dynamic OSPF routes automatically.

For CHG-8130, this choice fails Aspen: the branch administrator leaves the required Aspen condition unmet and, under t11-pt1-q19, should reject it for chg-8130.

 

Question 20

A Drift recursive static route uses next hop 198.51.100.9, which is reachable through a connected 198.51.100.0/24. What enables the route to forward traffic? Choose ONE.

  1. The routing table can resolve the next-hop address to an egress interface
  2. DNS learned a hostname for 198.51.100.9
  3. NTP synchronized the router clock
  4. HSRP elected 198.51.100.9 as active

Correct Answer: A

Correct Answer

 

 

Answer A is correct because The connected route supplies recursive resolution for 198.51.100.9, allowing the static destination route to determine where packets should leave. For CHG-8147 at Drift, the change reviewer checks Drift’s protocol state; CHG-8147 is judged from, under t11-pt1-q20, the observable result at drift. For CHG-8147, this choice fits Drift: the change reviewer gets the required Drift outcome and can verify CHG-8147 directly.
